18 Feb

$ (document).ready(function() { SampleGalleryV2({“containerId”:”embeddedSampleGallery_9106999890″,”galleryId”:”9106999890″,”isEmbeddedWidget”:true,”selectedImageIndex”:0,”isMobile”:false}) });

Leica has introduced the APO-Summicron-SL 28mm F2 ASPH lens for full-frame L-mount bodies. It features 13 elements, 6 of which are aspherical; several of the elements are of the anomalous partial dispersion type to reduce chromatic aberration.

The lens can focus as close as 24cm (9.5″) and the maximum magnification is 0.2X. The focus group is driven by a stepping motor that Leica calls ‘Dual Syncro Drive’. The 28mm F2 has a newly designed manual focus ring that uses magnetic fields to improve responsiveness and precision.

The 28mm F2 is weather-sealed and weighs in at 700g (1.5lbs) without its hood. It accepts 67mm filters.

The APO-Summicron-SL 28mm F2 ASPH is now available for $ 5195.

Press release:

Leica Launches the APO-Summicron-SL 28 f/2 ASPH.:

Exemplifying A Commitment to Developing High-Performing Innovative Technologies in the World of Camera Optics

February 18, 2021. With the APO-Summicron-SL 28 f/2 ASPH., Leica Camera presents yet another high-performance wide-angle lens for the Leica SL-System. The APO-Summicron-SL 28 f/2 ASPH. is the latest addition to the ever-expanding APO-Summicron-SL series that includes a lens range renowned for its top-level optical performance and extremely fast and reliable autofocus.

Following the existing focal lengths of 35, 50, 75 and 90 mm, the APO-Summicron-SL 28 f/2 ASPH. is the first true wide-angle prime lens in this series, making the APO-Summicron-SL 28 f/2 ASPH. especially suitable for reportage, interior and architectural photography. Its maximum aperture can be used without any loss of image quality and offers additional creative possibilities through the exquisite balance of sharp subjects and lovely soft background blur. Thanks to the L-Mount standard, the APO-Summicron-SL 28 f/2 ASPH. is equally compatible with cameras made by other partners of the L-Mount Alliance that have been equipped with the Leica-developed lens mount.

As is universally appreciated with all Leica lenses, the fastest aperture delivers maximum performance. As a result, reducing the aperture is only necessary for compositional and creative purposes. Leica lenses always deliver an exceptional quality of natural skin tones, soft transitions into creamy bokeh, contrast-rich details and edge-to-edge sharpness across a distortion-free image. Yet the APO-Summicron-SL 28 f/2 ASPH. is further distinguished by its apochromatic correction, which is a notable feature in a lens of this focal length, and its six aspherical lens surfaces. To ensure the optimal correction of chromatic aberrations, the majority of the grouped lens elements feature anomalous partial dispersion and are made of high-quality specialized glass. The end result is a wide-angle lens that delivers impeccable images complete with the “Leica Look” to help realize a creative vision in any avenue of photography.

The autofocus drive of all APO-Summicron-SL lenses utilizes extremely robust and high-performance stepping motors with DSD® (Dual Syncro Drive™). This enables the AF to travel the entire focusing range in around 250 milliseconds. Leica Camera also takes an innovative approach to manual focusing technology, including an entirely new manual focus ring construction in the form of an embedded ring magnet with alternating north-south polarization. When the ring is turned, the magnetic field changes its polarity. A sensor monitors the status of the magnetic field and sends the data to the main processor. The drive then shifts the lens to the corresponding focusing position based on the angle of rotation and the rotational speed, delivering even faster and more precise manual focusing to match the lens’s quick and accurate autofocus.

Both the construction and design of the cutting-edge APO-Summicron-SL series represent the next step forward in the development of lenses for the Leica SL-System. New, extremely precise manufacturing methods and measuring technologies have been developed specifically for the production of these lenses, resulting in more compact dimensions as well as truly outstanding imaging performance. In the construction of the APO-Summicron-SL lenses, particular attention has been paid to the prevention of stray light and reflections by applying a high-quality coating to the lens surfaces. Thanks to their effective sealing against dust, moisture, and water spray, as well as the Aquadura coating of the exposed lens surfaces, these extremely durable lenses can be used in nearly any weather condition without any cause for concern. The ever-expanding portfolio of Leica SL lenses are built to withstand the elements and the test of time, matching its futureproof counterparts in the SL2 and SL2-S with their rugged construction and continuing firmware development ensuring a long service life.

The APO-Summicron-SL 28 f/2 ASPH. is available now at Leica Stores, Boutiques and Dealers for $ 5,195.00.

Vazen announces new 28mm T2.2 1.8x anamorphic lens for Micro Four Thirds mount

17 Feb

Chinese cinema lens manufacturer Vazen has announced its latest anamorphic lens for Micro Four Thirds (MFT) cameras and teased another one that’s due out ‘in a few months.’

Vazen’s new 28mm T2.2 1.8x anamorphic lens for MFT camera systems is the second lens in its MFT anamorphic lineup, following up on its 40mm T2, an impressive anamorphic lens we had a little fun with on DPRTV. The new 28mm T2.2 features a lightweight design that Vazen claims makes it the ‘World’s Lightest 1.8x Anamorphic Lens for Panasonic GH5, Z-Cam E2 & Blackmagic Pocket 4k.’

It weighs just 720g (1.59lbs) and measures 80mm (3.15in) diameter and 107mm (4.2in) long. Its T-stop range is T2.2 through T16, it features a 72-degree angle of view and it has a minimum focusing distance of 82cm (2.7ft). Below is a sample video of footage captured with the lens on a ZcamE2(Vazen also shared this slightly NSFW music video captured with the lens):

In addition to the new 28mm T2.2 lens, Vazen also confirmed it’s adding a third lens to this lineup, a 65mm anamorphic lens. No details are given on the specs, but Vazen does not the 65mm lens ‘is expected to have the strongest anamorphic “character.”’

The Vazen 28mm T2.2 1.8x anamorphic lens for MFT camera systems is currently available to purchase through Vazen’s website for $ 3,250. If you purchase both the 28mm T2.2 and the 40mm T2 as a kit, Vazen drops the price for the pair by $ 400.

Review of the Sigma 28mm f1.4 Art DG HSM for Canon

03 Mar

The post Review of the Sigma 28mm f1.4 Art DG HSM for Canon appeared first on Digital Photography School. It was authored by Karthika Gupta.

A couple of weeks ago I got my hands on the Sigma 28mm f1.4 Art DG HSM for Canon (also  available for Nikon, and Sony) and got to play with it for a couple of weeks. Let me tell you; it was a tough one to give back. This lens is quite amazing in terms of build, weight, and, most importantly, performance.

Karthika Gupta Photography Sigma 28mm f1.4 review

Ergonomics and build

The Sigma 28mm f1.4 Art DG HSM is a very standard Sigma lens when it comes to the ergonomics. Many of their primes more or less follow the same formula when it comes to the exterior design. In this case, and with pretty much most cases, there is a large rubber ring that makes up the focusing ring. This rubber ring helps greatly when it comes to the grip and overall ergonomic feel of the lens. The front of the lens has a 77mm filter thread and comes with a lens hood. The side of the Sigma 28mm f1.4 Art DG HSM has a switch for autofocus control.

The Sigma 28mm f1.4 Art DG HSM has weather sealing built into the lens. I was able to test this when I took it out in the snow. We have had an unusual cold spell here in Chicago, and when I was walking around downtown with this lens, the temperatures dipped, and it started to snow. I was a bit apprehensive taking out my gear in the snow, but I am glad I did because this lens performed beautifully with my weather resistant Canon 5D MkIII. Photographers who regularly operate in the outdoors with rain and snow will find this beneficial.

When you hold the Sigma 28mm f1.4 Art DG HSM, you feel a solid lens. My primary everyday lens is a Canon 24-70mm f/2.8. This lens has been in my bag for the past 9 years, and I like the feel of the solid form and am comfortable with the weight. The Sigma 28mm is a bit smaller, and a little lighter than I am used to, so switching to it was a non-issue for me.

Karthika Gupta Photography Sigma 28mm f1.4 review

The canon 24-70mm f/2.8 is on the left and the Sigma 28mm f/1.4 is on the right.

Technical Specifications (from Sigma)

These specifications are from Sigma’s website.
Typical photography applications for this lens is listed as Creative, Travel, Landscape, Wedding & Events, Family. 
  • Best-in-class performance
  • Dust- and splash-proof structure
  • Designed to minimize flare and ghosting
  • Designed to meet all shooting conditions
  • Compatible with Canon Lens Aberration Correction
  • Nikon electromagnetic diaphragm mechanism included
  • Manual Override (MO) capable of switching two full-time manual modes
  • Lens angle is 75.4deg
  • Filter size is 77mm
  • Minimal aperture is f16
  • Minimal focusing distance is 28cm/11in

Performance

I gauged the performance of this lens in three different areas:

  • Low light performance
  • Color output
  • Wide angle

Low light performance

The Sigma 28mm features a very fast lens design at f/1.4. This makes it an ideal low light photography lens. Moreover, the mechanics of the lens also delivers incredible sharpness even at its widest aperture. I love photographing at wide apertures and am generally at f/2.8 or f/4.0. So the f/1.4 was attractive to me, especially in low light. I tested the low light performance at a couple of places in Chicago and was very happy with the results. The lens was also quite fast at focusing in these low light situations.

Thank you to my friend Sandy Noto (www.sandynoto.com) for snapping this photo of me with the Sigma. The wide angle at closeup range did not distort the image at all.

Karthika Gupta Photography - Memorable Jaunts Sigma 28mm lens review Chicago Museum Of Science and Industry Interiors

The interiors of the museum of science and industry in Chicago are quite dark but I was at ISO 320 and f/1.4. The 28mm captured the entire shuttle in the frame.

Color output

Sigma’s Art series is known for its superb color rendition, and the 28mm Art lens did not disappoint in this area. I tested the lens in a variety of lighting conditions, both indoors and outdoors, as well as on bright sunny days and overcast days. In each scenario, the lens output was beautiful.

Karthika Gupta Photography - Memorable Jaunts Sigma 28mm lens review low light Chicago Downtown

Even at f/1.4 the image output and quality was exactly what I was hoping for. The lens is tack sharp even at f/1.4

Karthika Gupta Photography - Memorable Jaunts Sigma 28mm lens review Chicago The Bean wide angle photo Karthika Gupta Photography - Memorable Jaunts Sigma 28mm lens review Downtown Chicago Yellow Taxi Cab

Wide angle

The Sigma 28mm f/1.4 is a fixed zoom lens. Unlike my Canon 24-70mm zoom which gives me more flexibility and freedom in the range of focal lengths, the fixed zoom does take a little bit getting used to. But if you were to use this as a walking-around-everyday-travel lens, which is what I use my 24-70mm, the fixed zoom is not an issue. The wide angle does take a little getting used to, but all the other features like fast focusing, low light, and superb color output make up for the wide-angle fixed zoom.

Karthika Gupta Photography - Memorable Jaunts Sigma 28mm lens review Chicago The Bean Wide Angle Photo in winter

The 28mm focal length was just perfect to get the entire Chicago bean a.k.a as the cloud gate in the frame.

Additionally, I found minimal to no chromatic aberration around the edges of the frame that is predominant in most wide-angle lenses.

Conclusion

Overall, I was very pleased with this lens. It is a good solid lens from the Sigma Art series and well worth the investment, making it an ideal lens for street photography and wide-angle photography.

Sigma announces 28mm F1.4 Art, 40mm F1.4 Art, 70-200mm F2.8 Sport and 60-600mm F4.5-6.3 Sport

26 Sep

Sigma has announced four lenses for Canon EF, Nikon F and Sigma SA mounts. The 28mm F1.4 DG and 40mm F1.4 DG are both part of the company’s premium ‘Art’ range that prioritize image quality over price and weight. These two lenses will also be available for the Sony E mount. The new lenses help round-out the series, which now includes a range of prime lenses extending from the 14mm F1.8 DG HSM up to the 135mm F1.8 DG.

The 28mm F1.4 DG adds a semi-wide option to Sigma’s impressive range of ‘Art’ prime lenses.
The 28mm F1.4 DG | Art has a 77mm filter thread, matching that of the 24mm F1.4.
The 40mm F1.4 DG | Art is a near perfect ‘normal’ lens: a close match for the diagonal length of a full frame sensor. It’s been a historically popular focal length, so we’re pleased to see its return.
The Sigma 40mm F1.4 DG | Art has an 82mm filter thread.

In addition, Sigma has introduced a redesigned, stabilized 70-200mm F2.8. The 70-200mm F2.8 DG OIS is, as you’d expect, part of the company’s Sport range of optics and is likely to offer a less-expensive alternative to OEM 70-200s. We will, of course, be testing its performance as soon as one becomes available.

Finally, Sigma has announced the 60-600mm F4.5-6.3 DG OIS, a monster telephoto lens, also part of its Sport range. Despite the sport designation, we suspect the lens will be used more for birding and airshow shooting.

The Sigma 60-600mm F4.5-6.3 DG | Sport is a substantial beast, even at its 60mm setting.
But that’s nothing compared to seeing it at full stretch. It certainly lives up to the ‘Bigma’ nickname of its predecessor.

As you’d expect, it features a focus limiter, OIS control switch. In addition, there’s a ‘Custom mode switch’ that can be used in conjunction with the Sigma USB Dock to access customized adjustments of the lens’s focus and stabilizer behavior.

Kamlan 28mm F1.4 for APS-C sample gallery

21 Jun

$ (document).ready(function() { SampleGalleryV2({“containerId”:”embeddedSampleGallery_6947377912″,”galleryId”:”6947377912″,”isEmbeddedWidget”:true,”selectedImageIndex”:0,”isMobile”:false}) });

The Kamlan 28mm F1.4 is an all-manual prime lens for APS-C (and Micro Four Thirds) mirrorless cameras. Following a successful Kickstarter campaign, it’ll go on sale to the public for $ 200, and after a bit of shooting we’d say that’s not a bad deal. It boasts a solid feel, and rings are smooth to turn and feel well-damped. A lack of optical coatings creates some unusual effects when shooting into the sun, and the lens provides no electronic communication with the attached camera body. That said, it’s hard to argue with a $ 200 price tag.

Take a look through our gallery to see what this budget-priced prime can do on Fujifilm and Sony bodies.

Kamlan 28mm F1.4 APS-C lens unveiled with upcoming Kickstarter campaign

01 Jun

Chinese company Machang Optics is preparing to launch its new Kamlan 28mm F1.4 MFT lens on Kickstarter, where the company currently has its project listed in draft. The latest Kamlan lens is billed as an inexpensive alternative to pricier lenses while offering the same “premium optical quality” paired with a versatile focal length, super-low chromatic aberration, and a full metallic body.

The Kamlan 28mm F1.4 APS-C lens features 7 groups in 8 elements, 11 circular blades, 0.25m minimum focusing distance, 0.15x max magnification, manual focus, 52mm filter thread, and a 348g / 12oz weight. Machang Optics says the manual aperture ring is de-clicked for smooth changes during video recording.

Despite its budget-tier cost, Machang claims its new Kamlan lens provides a “neutral, accurate color rendition” and excellent center sharpness. The company plans to offer its latest model in Canon EOS M, Micro Four Thirds, Sony E, and Fuji XF mounts.

Once live, Kickstarter backers will able to pledge $ 149 USD to the campaign for a single Kamlan 28mm F1.4 lens. Shipping to backers is expected to start in August, and the lens has an anticipated $ 199 USD retail price.

In addition to its new 28mm offering, Machang has revealed a product timeline for future lenses it plans to launch: 21mm F1.8 APS-C, 50mm F1.1 Mark2, 32mm F1.3 APS-C, and 15mm F1.8 APS-C. The company indicates it will launch these new lenses later this year.

A strange shootout: $5,000 Zeiss Otus 28mm F1.4 vs $4,250 Leica Q

31 Jan

PhotoShelter founder and CEO Allen Murabayashi recently decided to pit two unlikely competitors against each other. In a short, unscientific comparison review, Murabayashi wanted to see how the $ 5,000 Zeiss Otus 28mm F1.4 lens stacked up against the almost-as-expensive $ 4,250 Leica Q, which sports a fixed 28mm F1.7 lens.

When you consider the identical focal lengths and “must have deep pockets” price tags, the shootout almost makes sense—so Allen slapped the Otus on a Nikon D850 and went out shooting with both cameras. And despite the fact that Allen admits “it’s impossible to make a straight apples to apples comparison” when it comes to image quality—given the D850’s 45MP resolution compared to the 24MP Leica Q—he was still able to draw a pithy conclusion about who the Otus is made for, and why you might choose the Leica Q instead:

You can certainly make the argument that a 45MP sensor needs great glass, and in this regard, the Otus delivers the goods. But the slow operation of the lens turns a pretty great digital camera into something more like a large format camera.

If you like “slow” photography and have deep pockets, the Otus might be for you. If you just have deep pockets (and a bad back), stick with the Leica.

For a bit more depth, or if you want to check out some side-by-side comparison shots from PhotoShelter’s testing, watch the video above or check out the full written comparison on the PhotoShelter Blog.
