Review of the Tamron 18-400mm F/3.5-6.3 DI-II VC HLD Zoom Lens

22 Nov

Tamron has been specializing in super-zoom lenses for the last few years. You may be familiar with their 16-300mm, 18-270mm or 150-600mm lenses. Their newest super-zoom is an even more astonishing focal length, the Tamron 18-400mm. I recently had a chance to review this lens for a few weeks so I thought I’d give you an idea of who this lens is for, the good, the not-so-good, and my overall recommendation.

About this review

I know you already know this (because you read ALL my pieces for dPS, right? Right?!) but my lens reviews are pretty real world. I don’t sit in a lab or use techy gizmos to measure sharpness. I actually hold a lens in my hands and shoot with it. This lens was tucked in my favorite bag for most of August.

That said, my intention was to see how a lens holds up for an actual shoot. I used this lens to photograph Lipizzan horses at a dressage performance as well as at the racetrack. Then I used it on a mission to photograph old barns and finally to make some macro flower images.

The goal was to make images at most focal lengths with a variety of apertures, but a few might have been skipped because I was really out there shooting. I shoot at the focal length, shutter speed, ISO and aperture that each situation calls for. So let’s just say I apologize in advance if I’ve skipped something important to you. Give me a shout in the comments if that’s the case. I’ll dig through my notes and image archives to see if I can answer your question.

Lens specs

Let’s start off with a quick overview of the lens specs. This lens is for Nikon and Canon APS-C (crop sensor) cameras only. I tested the lens on a Canon 7D Mark II.

The Tamron 18-400mm super-zoom is a variable aperture lens. Meaning that at 18mm, the maximum aperture (largest opening) is f/3.5. But when you zoom into 400mm, the maximum aperture is f/6.3. The minimum aperture (smallest opening) is f/22 at all focal lengths.

The lens has an HLD Autofocus Motor that is quick and quiet for a consumer lens at this price. It also has Tamron’s standard VC Image Stabilization. This feature enables you to get sharper shots while hand-holding at longer focal lengths. The lens also has what Tamron calls Moisture-Resistant Construction. I’m relieved to tell you I didn’t get to test this feature.

The minimum focusing distance – important especially if you want to try your hand at making macro images – is 17.72″ (45 cm). Macro is usually a 1:1 ratio and this lens only produces 1:2.9, but I was pleasantly surprised with my macro results.

If you use screw on filters, like a circular polarizer, the front thread is 72mm. The lens is 1.56 pounds (710 g) and approximately 3.11” in diameter by 4.88″ in length (79 x 123.9 mm). It’s an incredibly compact lens for this focal length range.

The price, at the time of publication of this article, is $ 649.00 USD.

Who is this lens for?

I would describe the ideal user of this lens as an amateur or enthusiast. If you’re an amateur photographer who travels but doesn’t want to carry more than one or two lenses, this is the perfect choice for you.

With an 18-400mm focal length, you might not need to ever change the lens, except in a dark indoor situation, when you need either flash or perhaps the fast f/1.8 maximum aperture of a nifty fifty.

This lens would also be great for a busy parent who needs more than a smart phone to capture pictures of soccer matches and dance recitals but who doesn’t have a ton of extra room in her carryall bag. The compact size and weight of the Tamron 18-400mm make it an easy addition to any parent’s standard kit.

What’s good about this lens

The size of this lens just can’t be beat. At only a pound and a half and less than 5 inches long, it’s a lot of focal length in a very small package. I was really taken with how small it was since I normally shoot with such large neck-and-shoulder-busting glass.

Hand-holding this lens for an afternoon at the race track wasn’t even remotely painful. With the insane focal length capabilities, I didn’t even bother to carry a second lens with me (or even my camera bag!) and that made for a really care-free afternoon.

Great for landscape images

It’s also a pleasure to catch a pretty landscape out of the corner of your eye and to simply zoom out to 18mm to capture it. Typically if you’re shooting with a long lens, you have to take the time to switch over to your wide-angle lens, take the shot and then switch back to your longer focal length lens again. Well, actually, if you’re me, you see that landscape and think ooh, pretty and then walk away without taking the shot.

I’m lazy that way so this was the first time I’ve actually made images of the racetrack itself. The lens performed really well in the 18-50mm focal range. It was both sharp and relatively distortion free. Lightroom’s Lens Correction easily managed the slight distortion there was too.

Things to be careful of

Remember I said we’d talk about the not-so-good too? It is a touch tricky to twist the lens in order to zoom in past 200mm to get to the 400mm focal length. First, your hand gets a bit “stuck” since anatomically, your wrist only twists so far before you have to reposition in order to continue the twisting motion.

Second, the lens has what I call a “hiccup” where you need to exert more pressure to push it past this point. I missed a few shots because the twisting motion wasn’t smooth enough and I jerked the lens a bit as I zoomed in from 200mm to 400mm.

Softness around the edges

There is a definite softness (or loss of sharpness) at the longer end of the lens, especially when your aperture is wide open, e.g., 400mm at f/6.3. If you crop in too much during post-processing or print too large, you’ll start to see the loss of fine details in your image since they weren’t tack sharp to start. You won’t see this loss of detail in a small 5×7″ print, or if you post to social media – so for many people, this actually won’t be a big issue.

Tamron 18-400mm lens Review - Riders up

Riders up at the paddock, Arlington Park IL. Canon 7D Mark II, Tamron 18-400mm lens @ 18mm, f/5, 1/500th, ISO 640, handheld.

Use the center focus point

The lens tends to be softest in the corners so sharpness improves if you use your camera’s center focus point. It also improves if you close down your aperture to f/8, f/9, or smaller. Because the lens is not tack sharp all the way through the focal length spectrum, I’m not recommending this lens for super serious wildlife shooters or anyone who likes to print really large. For you guys, I’m going to suggest sticking with a more standard zoom lens like a 100-400mm or 200-400mm. (I apologize in advance for the wear and tear this recommendation will cause your shoulders.)

If you predominantly shoot wide-angle images, like landscapes, and only occasionally shoot long, this lens will be a good fit for you when you don’t want to carry a ton of gear.

Final thoughts

Ultimately there were a number of things I really liked about this lens. The small size and super-zoom focal length make it a very practical tool to have in your bag. At $ 649.00 USD, it’s also a great value.

However, the softness at the long end of that focal length can become a real issue if you’re not careful. Because of that, I’m cautiously going to rate this lens 3.5 stars out of 5.

I’d love to hear your opinions too. Have you tried super-zooms lenses? Do they work for your type of photography? Which is your favorite one and how does it compare to the Tamron 100-400mm lens? Please share your thoughts with the dPS community in the comments below.

Field Test and Thoughts: Tamron 24-70mm F/2.8 Di VC USD G2 Lens

15 Nov

Ask any experienced photographer what his or her all around go-to lens is, and odds are high that the response will be the 24-70mm f/2.8. Not only does it cover a useful range, but the fast aperture makes it ideal for shooting in low lighting conditions when you don’t have a prime lens handy. The long-standing problem with this lens? It is notoriously pricey. Enter the new Tamron 24-70mm f/2.8 G2 lens!

Tamron 24-70mm

Along with Sigma, Tamron has been upping its lens game recently by offering high-quality budget versions of popular lenses. In fact, the original Tamron 24-70mm f/2.8 lens (Model A007) was first announced in February 2012 and has been on the market for awhile. This year, a highly anticipated second version was released. Here’s what the specs are and what I think after comparing it to my Canon 24-70mm f/2.8 II.

Tamron 24-70mm

The Specs

The official name of this lens is a mouthful: Tamron SP 24-70mm F/2.8 Di VC USD G2 (Model A032). Let’s dissect some of that terminology.

SP is Tamron’s version of high-end lenses, similar to the Sigma Art series. The Tamron SP 24-70mm joins a handful of mostly prime lenses with this designation. Di stands for Digitally integrated, meaning the lens will perform well on full-frame and APS-C format cameras. VC refers to Vibration Control, which Tamron says is much improved in this new lens, offering around 5-stops of compensation, a big boost over its predecessor. USD stands for Ultrasonic Silent Drive, which is reasonably quiet. Finally, G2 is short for Generation 2; this, along with the model number, differentiates this lens from the original.

This lens is available in both Canon and Nikon DSLR mounts.

Tamron 24-70mm

Price

First of all, let’s talk about price. The original Tamron 24-70mm f/2.8 was announced in 2012 with a price of $ 1,300. Somehow, version II came out several years later with the even lower price of $ 1,199.00. Compare that to the current prices of the Canon ($ 1,699)and Nikon ($ 2,397) versions. Price-wise, it even beats out the Sigma version ($ 1,299). While Tamron’s version is still pricey, it’s the least expensive option on the market. That’s good news for photographers on a budget.

Lens Hood

This feature was so good it deserves its own heading.

Like most lenses, the Tamron 24-70mm f/2.8 G2 comes with a lens hood. Unlike most other lenses, the hood is solidly built and snaps into place very tightly. Once the hood is on, there’s almost no way that it will accidentally fall off as it inevitably does when shooting with other lenses.

Tamron 24-70mm

Build Quality

Following in the tradition of other Tamron SP lenses, the 24-70mm f/2.8 G2 is very solidly built. Its outer barrel is made mostly of metal instead of plastic and has moisture resistant construction. As a trade-off for the lens’ solid build, it is pretty big and bulky at nearly 11 cm (4.3″) long and 900 grams (approx. 2 lbs) in weight. That’s 75 grams (2.6 oz) heavier than the original! As a result, this lens might be tough to balance on small, lightweight camera bodies. During this test, the lens was paired with a Canon 5D Mark III, where it felt reasonably well-balanced.

Lens Switches

There are several switches located on the sides of the lens. One is an AF/MF switch making it easy to go from Autofocus to Manual focus. Nearby is the Vibration Control (VC) switch. Whether you choose to turn VC on or off depending on what you’re shooting, but it definitely helps with handheld shots.

The final switch is unique to Tamron zoom lenses: a Lock switch that holds the lens at 24mm, preventing it from extending. I have this unintended lens extension problem (it’s called zoom creep) with my Canon 24-70mm f/2.8 II (probably from prolonged use) and would love to see this feature on every zoom lens.

Tamron 24-70mm

Image Quality

Tamron’s SP lenses come with a special coating that significantly reduces ghosting or lens flare. In the case of the 24-70mm f/2.8, there was little evidence of flare when shooting into the sun or into bright light.

Tamron 24-70mm

When shooting wide open at f/2.8, there’s noticeable light fall-off in the corners of the image. It’s hard to get rid of the vignette without using an f-stop of f/5.6 or smaller.

Tamron 24-70mm

Shot wide open at f/2.8, there is a noticeable edge vignette on the corners of the image.

Tamron 24-70mm

Shot at f/11. Little to no vignette.

Image sharpness was comparable to what you would get from a 24-70mm f/2.8 of another brand. Shooting handheld wide open at low shutter speeds produced a reasonably sharp image with the Vibration Compensation activated.

Tamron 24-70mm

Shot handheld at 1/15th shutter speed and f/2.8.

Below, the lens was used in a controlled studio environment with off-camera flash, thus reducing camera shake and noise. The resulting images are sharp with nice coloring.

Tamron 24-70mm

Food Photography Tamron 24-70

Some users have reported distortion from shots taken at the 24mm focal length. When shooting interiors, I did notice a bit of distortion on the edges, but it’s nothing that can’t be fixed in post-processing if you really wanted to.

In Conclusion

If you’re on the hunt for a great 24-70mm lens, the Tamron 24-70mm f/2.8 G2 is a great option. It produces great image quality with a solid build, and most importantly, it won’t break the bank.

Do you own a 24-70mm lens? Would you try Tamron’s version? Or do you prefer to stick with your camera’s name brand lenses? Tell us about your experience below.

Tamron unveils lightweight 100-400mm F4.5-6.3 ultra-telephoto zoom for $800

29 Oct

Tamron just revealed its newest ultra-telephoto zoom. Meet the Tamron 100-400mm F4.5-6.3 Di VC USD (Model A035) for full-frame Canon and Nikon DSLRs—a lens that combines compact, lightweight construction with ‘superior’ image quality and ‘fast and precise AF’, according to Tamron. The lens’ tagline: heavyweight performance in a lightweight lens.

The new lens was revealed this morning, and its claim to fame is its size and weight. At just 39.3 oz., the new 100-400mm lens is the lightest in its class thanks to the use of magnesium allow in ‘key areas’ of the lens barrel. Inside that barrel you’ll find 17 lens elements in 11 groups—including three low dispersion (LD) elements—and Tamron’s high-speed Dual MPU that allows for ‘fast and precise AF’ as well as four stops of stabilization.

Below are some sample photos captured with the new Tamron 100-400 F4.5-6.3 Di VC USD at the racetrack by photographer Takahito Mizutani for Tamron:

$ (document).ready(function() { SampleGalleryV2({“containerId”:”embeddedSampleGallery_8730107360″,”galleryId”:”8730107360″,”isEmbeddedWidget”:true,”standalone”:false,”selectedImageIndex”:0,”startInCommentsView”:false,”isMobile”:false}) });

The Tamron 100-400mm F4.5-6.3 Di VC USD will be available starting November 16th, in both Canon and Nikon mounts, for $ 800. To find out more or see more impressive sample photos, read the full press release below or head over to the Tamron website.

Press Release

100-400mm F/4.5-6.3 Di VC USD (Model A035)

Tamron announces the launch of a new ultra-telephoto zoom lens with fast and precise AF, superior image quality and a lightweight, compact design

October 26, 2017, Commack, New York— Tamron USA, Inc. , announces the launch of a new ultra-telephoto zoom lens, 100-400mm F/4.5-6.3 Di VC USD (Model A035), for full-frame Canon and Nikon DSLR cameras. The Model A035 delivers fast and precise AF performance and consistently powerful VC (Vibration Compensation) 4 stops*1 benefits thanks to the high-speed Dual MPU (Micro-Processing Unit) control system that is found in the latest Tamron lens models. The advanced optical design of Model A035 includes three LD (Low Dispersion) lens elements for aberration reduction and Tamron’s original eBAND Coating for superior anti-reflection performance. At 1,115g (39.3 oz), the new lens is the lightest in its class*2 and features magnesium alloy in key areas of the lens barrel to ensure weight reduction, and improve strength and portability. Model A035 is compatible with Tamron’s 1.4X tele converter and the Tamron TAP-in ConsoleTM that enables lens customizations for focus adjustments, VC mechanism adjustments and more. Additionally, an Arca Swiss compatible tripod mount is available as an optional accessory. The new Tamron 100-400mm will be available in both Canon and Nikon mounts on November 16th at $ 799.

PRODUCT HIGHLIGHTS

1. High-speed Dual MPU (Micro-Processing Unit) control system delivers quick and highly responsive autofocus performance plus outstanding VC image stabilization

The Dual MPU system includes an MPU dedicated to vibration compensation processing, enhancing the computational capacity of the entire system. An MPU with built-in DSP (Digital Signal Processor) provides high-speed digital signal processing and achieves outstanding autofocus performance and vibration compensation, both indispensable for ultra-telephoto photography.

2. Superb image quality in an ultra-telephoto zoom lens

The Model A035 includes three LD (Low Dispersion) lens elements for optimal optical design and aberration correction. Lighter weight, increased light transmission and crisp images with excellent contrast are achieved by reducing the number of lens elements while ensuring an appropriate balance with aberration correction. The A035 has minimum object distance (MOD) of 1.5 m (59 in) and a maximum magnification ratio of 1:3.6 for close-up work.

3. Exclusive eBAND Coating reduces flare and ghosting

The new A035 features Tamron’s eBAND (Extended Bandwidth & Angular-Dependency) Coating, which has an extremely low refractive index and fine multiple-layer coating technology, to achieve outstanding antireflection performance. BBAR (Broad-Band Anti-Reflection) Coating, with excellent antireflection characteristics, increases light transmission. These coating technologies greatly reduce the ghosting and flare that can occur when subjects are backlit.

4. Lightest weight, 1,115 g (39.3 oz) lens in the ultra-telephoto zoom lens class*, and only 196.5 mm (7.7 in) long

Magnesium alloy is used in key areas of the lens barrel to improve weight reduction, strength and portability. Total length of 196.5 mm (Nikon mount) means a compact size for an ultra-telephoto zoom lens covering up to 400 mm, and the A035 can therefore be easily carried in a standard camera bag. Combined with excellent vibration compensation functions, the compact size enables successful handheld ultra-telephoto photography.

*Length is the distance from the front tip of the lens to the lens mount face.

5. Optional accessory tripod mount is Arca-Swiss compatible

An Arca-Swiss style tripod mount is available as an optional accessory. Designed exclusively for Model A035, it provides quick and secure attachment to a tripod and greater stability. An easy-to-hold grip shape includes an expanded mounting plane, and the use of magnesium helps achieve lighter weight, thereby further facilitating handheld photography.

6. Compatible with tele converters and TAP-in Console

Model A035 is compatible with tele converters designed exclusively for Tamron lenses to achieve 1.4X and 2X the original focal length*. It’s also compatible with Tamron’s TAP-in Console (Model TAP-01), an optional accessory enabling users to update lens firmware and customize the lens settings, including adjustments of focusing positions for autofocusing and the operation modes for the lens’s Vibration Compensation system.

*Use of the 1.4× tele converter results in light reduction of 1 F stop; use of the 2× tele converter results in the loss of 2 F stops

7. Moisture-Resistant construction and fluorine coating for enhanced weather protection

The surface of the front element is coated with a protective fluorine compound that has excellent water- and oil-repellant qualities. The front surface is easier to wipe clean and is less vulnerable to the damaging effects of dirt, dust, moisture or oily fingerprints, allowing for much easier maintenance. Also, with active use of the A035 for outdoor photography likely, sealant is used in each of the movable and joining areas of the lens barrel to resist the intrusion of moisture.

8. Electromagnetic diaphragm system now used also for Nikon-mount lenses

An electromagnetic diaphragm system, which has been a standard feature for Canon-mount lenses, is now employed in Nikon-mount lenses*. More precise diaphragm and aperture control is possible because the diaphragm blades are driven and controlled by a built-in motor through electronic pulse signals.

* Available only with cameras compatible with the electromagnetic diaphragm (D5, D4s, D4, D3X, Df, D850?D810, D810A, D800, D800E, D750, D600, D610, D300S, D500, D7500, D7200, D7100, D7000, D5600, D5500, D5300, D5200, D5100, D5000, D3400, D3300, D3200, D3100). (As of October, 2017; Tamron)

9. External design places importance on functionality and ease of use

While inheriting the design that makes use of many organic curves and the delicately polished form down to fine details that characterize the SP lens series, the new Model A035 comes with a highly sophisticated design that also places a lot of importance on the lens’s functionality and ease of use, featuring an overall form that faithfully encompasses the internal structures within, a slim Luminous Gold brand ring and the switch shape design.

Hands-on with new Tamron 100-400mm F4.5-6.3 Di VC USD

27 Oct

Hands-on with new Tamron 100-400mm F4.5-6.3 Di VC USD

The new Tamron 100-400mm F4.5-6.3 Di VC USD is a lightweight telezoom aimed at enthusiast full-frame and APS-C DSLR users. The lightest zoom in its class (minus the optional tripod foot) the 100-400mm trades brightness for portability, weighing in at 40 ounces (roughly 1.1 kilograms).

Hands-on with new Tamron 100-400mm F4.5-6.3 Di VC USD

Optical construction comprises 17 elements in 11 groups, including extraordinary LD (low dispersion) elements. Minimum focus is a respectable 59 inches (1.5m) which works out at a a maximum magnification ratio of 1:3.6.

The optical Vibration Correction system offers the equivalent of 4 stops of correction, which should make a big difference to usability for telephoto shots, at and around 400mm. We’ve been impressed by the performance of Tamron’s stabilization in the past, and in theory, the new 100-400mm should be hand-holdable down to 1/60sec at 400mm.

Hands-on with new Tamron 100-400mm F4.5-6.3 Di VC USD

Despite being a full-frame zoom, the 100-400mm feels relatively light, and very well-balanced. In the 100mm zoom position, the lens is 7.8 inches long.

Hands-on with new Tamron 100-400mm F4.5-6.3 Di VC USD

Zoomed out to 400mm, the 100-400mm gets longer by roughly 50%, but still feels well-balanced. The large zoom ring moves smoothly throughout the zoom range. A smaller focus ring is positioned behind it, but separated by enough space that you probably won’t grab the wrong ring by mistake.

Automatic focusing is powered by twin processors, and judging from a very quick test on the show floor (with a Nikon D500) AF seems fast and positive, at least in single-shot mode.

Hands-on with new Tamron 100-400mm F4.5-6.3 Di VC USD

Although the sample we tried out didn’t display any ‘zoom creep’ there is a lock on the barrel to prevent the lens extending when carried.

Hands-on with new Tamron 100-400mm F4.5-6.3 Di VC USD

The tripod ring is optional, but recommended. Although it makes the 100-400mm slightly heavier, it offers a very solid platform for tripod use. Although you can’t tell from this image, the base of the foot is Arca-SWISS compatible.

Hands-on with new Tamron 100-400mm F4.5-6.3 Di VC USD

The Tamron 100-400mm F4.5-6.3 Di VC USD is fully compatible with Canon and Nikon DSLRs, both full-frame and APS-C. We had the chance to use it (briefly) on a Nikon D500 and it balances well, both at 100 and 400mm positions. This view gives a sense of the relatively small size of the lens. Despite its telephoto reach, it’s about the same size and weight as a typical 70-200mm F4.

As we’d expect, the Tamron 100-400mm F4.5-6.3 Di VC USD is compatible with Tamron’s TAP-in Console and 1.4X and 2X teleconverters (although don’t expect stellar AF performance at the long end of the zoom with either!). It will be available starting November 16th for $ 800.

Tamron developing lightweight, compact 100-400mm F4.5-6.3 lens

18 Sep

Third-party lens maker Tamron has officially announced that it is working on a new tele-zoom lens for full-frame cameras: the 100-400mm F/4.5-6.3 Di VC USD (Model A035).

Thanks to the use of magnesium in key areas of the barrel, Tamron claims the lens is both durable and, weighing in at just 1.12kg, the lightest in its class. The optical design incorporates three low dispersion elements to control chromatic aberration and Tamron’s eBAND (Extended Bandwidth & Angular-Dependency) coating to minimize reflections and flare.

Tamron also included a high-speed Dual MPU (Micro-Processing Unit) control system, which works in conjunction with Tamron’s Ultrasonic Silent Drive focusing motor to deliver AF speed and precision.

The lens will be compatible with Tamron’s 1.4X teleconverter and the Tamron TAP-in Console that lets you fine-tune and adjust focus and stabilization, among other parameters. An Arca Swiss compatible tripod mount will be available as an optional accessory.

If everything goes to plan, the 100-400mm F/4.5-6.3 Di VC USD will be available by the end of 2017 in Canon and Nikon mount versions.

28 Jul

The Tamron 18-400 F3.5-6.3 wants to be the only lens you’ll ever need. In my experience, lenses of this nature tend to offer zoom versatility at the cost of sharpness, especially at the telephoto end of the zoom range. But I was pleasantly surprised by how solid this ‘ultra-telephoto’ performs at all focal lengths in bright, direct light.

More specifically, I found it produced adequately sharp images throughout the zoom range with acceptable levels of CA, distortion and vignetting. It’s also a fun lens to use, given its focal length range and reasonable size. As a bonus, it also offers a surprisingly close focus distance at the long end (see image at the bottom of this page).

See our Tamron 18-400mm F3.5-6.3 sample gallery

Available for both Canon and Nikon APS-C camera bodies (it offers an equivalent zoom range of 27-600mm on Nikon’s DX format, and 29-600mm on a Canon) I used the 18-400mm with the Canon EOS 80D, and and in terms of size and balance, it proved a good pairing. Despite having a plastic housing, the 18-400mm is reassuringly solid, and unlike some cheaper zooms the mount is made of metal. A small rubber ring around the mount is a reminder that the lens is also moisture-resistant.

Vibration Control is a useful feature given the insane zoom range – I definitely noticed it kicking in while shooting.

The wide, 27mm equivalent. And the tele, 600mm equivalent.

The lens also offers a nifty locking mechanism when zoomed to 18mm. This is a great way to avoid the dreaded ‘lens creep,’ though I found even without using the lock, the lens never crept when left at or near 18mm. The body also offers an AF/MF toggle, in addition to a VC on/off switch.

Overall, the Tamron 18-400mm F3.5-6.3 strikes me as a great and versatile lens for most daylight shooting scenarios. Travelers in particular will find it useful. And though it is heftier than your average kit lens, at 24.9oz / 705g, it shouldn’t weigh you down too much.

I was impressed by the close focus distance when shooting at the tele end.

Press Release

INTRODUCING THE WORLD’S FIRST1 ULTRA-TELEPHOTO ALL-IN-ONE ZOOM LENS WITH AN EXTENDED RANGE THAT COVERS 18-400MM

Dramatic extended range achieved by combining cutting-edge optical design and other new breakthrough technologies including a redesigned cam structure

18-400mm F/3.5-6.3 Di II VC HLD (Model B028)

June 23, 2017, Commack, NY – Tamron, a leading manufacturer of optics for diverse applications, announces the launch of the new 18-400mm F/3.5-6.3 Di II VC HLD (Model B028), the world’s first ultra-telephoto all-in-one zoom lens for APS-C DSLR cameras, which covers a focal length range of 18-400mm. Since the 1992 launch of its AF28-200mm F/3.8-5.6 Aspherical (Model 71D), Tamron has dominated the all-in-one zoom category and has produced many lenses that cover wide-angle to telephoto zoom ranges. Tamron has now developed an ultra-telephoto all-in-one zoom that extends to 400mm (35mm equivalent of 620mm) and a 22.2x zoom ratio. Packed in a light, compact body (4.8in./24.9oz.)2 is Tamron’s accumulated knowledge and experience for all-in-one zoom lenses, including the most advanced optical and mechanical designs, an HLD (High/Low torque modulated Drive) for the AF system and the Vibration Compensation system. Photographers can now enjoy wide-angle to ultra-telephoto photography using one lens, which is ideal for travel photography and eliminates the need to carry extra lenses. The new Model B028 lens enables photographing a wide variety of ultra-telephoto images including everyday casual scenes. The 18-400mm will be available in the U.S. at the end of July at $ 649.

PRODUCT HIGHLIGHTS

  1. The world’s first3 ultra-telephoto all-in-one zoom lens to achieve 400mm telephoto

The new Model B028 is the world’s first lens for APS-C DSLR cameras that covers a focal length range of 18-400mm and achieves a zoom ratio of 22.2x. The focal length of 400mm on the telephoto end enables the capturing of ultra-telephoto pictures with the 35mm equivalent of 620mm angle of view. Now, with just this one lens, a photographer can readily enjoy the power of ultra-telephoto to bring distant subjects closer as well as the perspective-flattening effects that only extreme telephoto settings can achieve. This all-in-one zoom lens is ideal for travel and everyday shooting. It allows a photographer to switch from wide-angle to ultra-telephoto without changing lenses, making it faster and easier to capture a much wider range of subjects including travel scenes, wildlife, action sports, landscapes, cityscapes, portraits and food.

  1. Excellent image quality across the entire zoom range, from wide-angle to ultra-telephoto and macro

The optical construction of the B028 consists of 16 lens elements in 11 groups. The use of specialized glass elements such as LD (Low Dispersion) and aspherical lens elements effectively minimizes wide-ranging aberrations, including chromatic aberrations and distortion, thereby assuring outstanding image quality. Optimum power distribution among the individual lens element groups achieves both the optical performance and the compact size necessary for an ultra-telephoto all-in-one zoom lens that boasts 400mm focal length. Also, it enables tele-macro photography with a maximum magnification ratio of 1:2.9.

  1. Lightweight and compact design exhibits Tamron’s basic philosophy for all-in-one zoom lenses

Despite being an all-in-one zoom lens that achieves 400mm ultra-telephoto, Model B028 is light and compact with a total length of 4.8in. and a weight of 24.9oz.4 A new lens barrel design utilizing three-step extensions was developed to enable the necessary elongation to produce a 22.2x zoom ratio. Compared to the conventional approach, the division into a larger number of cams ensures comfortable operation and stability while zooming. Tamron’s philosophy for all-in-one zoom lenses is to allow each photographer to casually capture everyday photos with a lens of a practical size, and Model B028 fulfills this philosophy.

  1. HLD motor provides high-precision AF and enables compact lens construction

The AF drive system for Model B028 uses Tamron’s exclusive HLD (High/Low torque modulated Drive) motor. The power-saving HLD motor produces outstanding driving torque, and adjusts motor rotation from low to high speed to enable accurate and quiet focusing. The HLD motor takes up less space thanks to its small size and circular arc shape that allows the size of the lens to be reduced.

  1. Equipped with the Vibration Compensation system necessary for ultra-telephotography at 400mm

Despite its compact size, Model B028 is equipped with Tamron’s proprietary VC (Vibration Compensation) system, which effectively curbs camera shake under low light conditions (such as a dimly lit room or at dusk) and while taking ultra-telephoto pictures. This greatly expands opportunities for casual handheld shooting. The jitter-free stability of the viewfinder image allows for easier framing and enables the photographer to compose the subject quickly and comfortably.

  1. Electromagnetic diaphragm system now used also for Nikon-mount lenses

The electromagnetic diaphragm system, which has been a standard feature for Canon-mount lenses, is now employed in Nikon-mount lenses5. More precise diaphragm and aperture control is possible because the diaphragm blades are driven and controlled by a motor through electronic pulse signals.

  1. User-friendly features for everyday comfortable use

With an eye toward active outdoor photography, Model B028 features Moisture-Resistant Construction to ensure worry-free shooting as well as confidence while shooting under adverse weather conditions. Also, the Zoom Lock mechanism prevents undesired movement of the lens barrel under its own weight when the camera is angled downward while walking.

  1. Compatible with TAP-in ConsoleTM, an optional accessory product

The optional TAP-in Console provides a USB connection to a personal computer, enabling the user to easily update the lens’s firmware as well as to customize features, including fine adjustments to the AF and VC.

  1. External design placing importance on functionality and ease of use

While inheriting the design that makes use of many organic curves and the delicately polished form down to fine details that characterize the SP lens series, the new Model B028 comes with a highly sophisticated design that also places a lot of importance on the lens’s functionality and ease of use, featuring an overall form that faithfully encompasses the internal structures within, a slim Luminous Gold brand ring and the switch shape design.

Lensrentals: Tamron 70-200 F2.8 G2’s resolution is excellent

08 Apr

Roger Cicala over at LensRentals has put Tamron’s new SP 70-200mm F2.8 Di VC USD G2 lens to the test. 

Cicala notes that on its own, the Tamron is impressively sharp all the way to the edges at its wide end, and even better in the middle of its focal range. Sharpness drops a bit at full telephoto, but Cicala still says the 70-200 ‘puts in a very good performance.’

The Tamron SP 70-200 F2.8 G2 impresses at its wide end of 70mm.

The Tamron’s performance is comparable to Canon’s 70-200 F2.8L II, though a bit softer at the wide end. When put up against what Cicala calls ‘the best 70-200 zoom on the planet’ – the Nikon F2.8 FL ED VR – the Tamron struggles to keep up, though the gap narrows at 200mm.

Sample variation from ten Tamron SP 70-200 G2 lenses at 70mm.

In addition to lots of MTF charts, Cicala provides some helpful information about copy variation using ten of the new Tamron 70-200mms.
