Hands on with Tamron 70-200mm F2.8 and 10-24mm F3.5-4.5 ‘G2’ zooms

Tamron announced two zoom lens updates at this year’s WPPI show in Las Vegas – the full-frame SP 70-200mm F2.8 Di VC USD G2 and the APS-C format 10-24mm F3.5-4.5 Di II VC HLD. Technically, both are ‘updates’ to older products, but the improvements are fairly significant. This is the 70-200mm F2.8, mounted on a Canon EOS 5D Mark II.

The ‘G2’ 70-200mm F2.8 now carries the ‘SP’ designation, which Tamron reserves for its highest-end lenses. The lens has been completely redesigned, and the new optical design consists of 23 elements in 17 groups. These include extra low dispersion and low dispersion elements to reduce chromatic aberrations.

Mechanically, there have been some changes too. Like Nikon’s new 70-200mm F2.8E, the Tamron 70-200mm F2.8’s zoom ring can be found near the front of the lens, while the focus ring is positioned closer to the camera. Feel free to argue about whether this is a good idea or not in the comments. Minimum focus distance is unequivocally improved, being reduced to 95cm (37.4″) from the previous model’s 130cm (50.7″).

Autofocus performance has also been improved, thanks (according to Tamron) to the inclusion of two microcomputers and a new AF algorithm. Vibration Compensation (VC) is enhanced too, and can now compensate up to a claimed 5 stops.

The removable tripod collar can be loosened and removed over the lens mount (as opposed to clamshell designs which can be attached and detached when the lens is mounted to a camera). The Nikon mount version of this lens now offers electronic aperture actuation, which is becoming standard on all newer Nikon lenses and should improve exposure accuracy, especially during high framerate burst shooting.

Build quality seems excellent, as we’ve come to expect from all of Tamron’s new generation of ‘SP’ lenses. Dust and moisture seals (including a grommet around the lens mount) help to keep the 70-200mm safe when shooting in tough conditions. The front element is fluorine coated, which should make it easy to quickly clean off water or oily fingerprints.

And here’s the 10-24mm F3.5-4.5 Di II VC HLD. Designed for APS-C format DSLRs, this wide-angle zoom covers an equivalent focal length range of 15-36mm (16-38mm equiv on Canon).

The biggest change in this lens compared to its 2008 predecessor is the addition of Vibration Compensation. Tamron claims 4 stops of compensation, which means that in theory, it should be possible to hand-hold exposures of up to ~1 second at 10mm. Don’t quote us on that, though.

The 10-24mm zoom features Tamron’s new HLD (High/Low torque modulated Drive) AF motor, for smooth and fast autofocus. We’ve only had a few minutes with a prototype lens, but just anecdotally, focus certainly seems fast. Optically, this new lens differs from its predecessor by offering more elements (16, as opposed to 12) in more groups (11, compared to 9) including one LD (Low Dispersion) lens element, one XLD glass element, one molded glass aspherical element, and one hybrid aspherical lens.

Again, the 10-24mm is sealed against dust and moisture, and build quality is excellent. Like the 70-200mm F2.8 G2, versions of this lens for the Nikon mount now feature fully electronic aperture actuation, allowing aperture to be changed during live view.

We’re looking forward to getting our hands on a production sample to see whether the various upgrades have made a significant difference to image quality. 

The Tamron 70-200mm F2.8 Di VC USD G2 is expected to arrive in March for $ 1299. The Tamron 10-24mm F3.5-4.5 Di II VC HLD is slated for availability this spring for $ 499.

Tamron announces 2nd generation SP 150-600mm Di VC USD ‘G2’

01 Sep

Tamron has announced a new version of its popular 150-600mm telezoom – the SP 150-600mm F5-6.3 Di VC USD G2. The ‘G2’ stands for second generation, reflecting several improvements to the design.

These improvements include more effective image stabilization (to a claimed 4.5 stops of benefit), faster AF speed and compatibility with Tamron’s ‘TAP-in’ Console, for lens firmware updates and customization. A ‘Flex Zoom Lock’ mechanism has also been added to keep the lens barrel fixed at any focal length. Flourine coating has been added to the front lens element, and the entire lens barrel offers greater moisture resistance.

The SP 150-600mm F5-6.3 Di VC USD G2 will sell for $ 1399 and will go on sale in Japan starting September 23rd in Nikon and Canon mounts, arriving in the US soon after. A Sony A-mount version will follow later. A pair of new teleconverters designed for use with the 150-600mm have also been announced.

Press release

INTRODUCING THE PINNACLE OF ULTRA-TELEPHOTO ZOOMS WITH ADVANCED FEATURES, ENHANCED PERFORMANCE, AND IMPROVED ERGONOMICS

New generation “G2” lens boasts faster AF speed and enhanced VC

SP 150-600mm Di VC USD G2 (Model A022)

September 1, 2016, Commack, New York – Tamron, a leading manufacturer of optics for diverse applications, announces the launch of the SP 150-600mm F/5-6.3 Di VC USD G2 (Model A022). This second generation “G2” lens builds upon the success of the SP 150-600mm F/5-6.3 Di VC USD (Model A011), which launched in December 2013 and continues to successfully meet photographers’ needs in the ultra-telephoto category. The new G2 version was developed to provide superior optical performance with today’s high resolution DSLRs and to add improvements to several features including speed and accuracy of AF and VC (Vibration Compensation). Also, several new features have been added: FLEX ZOOM LOCK mechanism, Fluorine Coating and optional teleconverters. The new lens delivers outstanding performance and a luxurious, upscale appearance, including a metal lens barrel.

Delivery of the new lens in Canon and Nikon mounts will start on September 23 in the Japanese market and soon thereafter in the U.S. market (Sony A-mount to be delivered at a later date) at a price of $ 1399.

PRODUCT HIGHLIGHTS

1. Optical design refreshed to achieve even higher performance
Three LD (Low Dispersion) lens elements completely eliminate axial and transverse chromatic aberrations. The design also features an upgraded optical construction (21 elements in 13 groups) and leverages improvements in manufacturing technology. As a result, the lens delivers high resolution, improved sharpness and overall better performance.

2. Tamron’s sophisticated eBAND Coating for eliminating ghosting and flare
eBAND (Extended Bandwidth & Angular-Dependency) Coating is a nano-structured layer deployed on the lens element surface. In addition to regular anti-reflection coatings, eBAND Coating offers higher light transmission and significant improvement in anti-reflection characteristics, especially against angulated incident rays. Combined with BBAR (Broad-Band Anti-Reflection) coatings, flare and ghosting are reduced to imperceptible levels.

3. MOD reduced to provide optimum tele-macro photography
Tamron’s advanced manufacturing technology has made it possible to reduce the MOD (Minimum Object Distance) to 86.6 in (2.2m), compared to 106.3 in (2.7m) for Model A011, and has allowed for the wonders of tele-macro photography with its 1:3.9 Maximum Magnification Ratio.

4. AF speed is faster and much more responsive with moving subjects
The Model A022 is equipped with a USD (Ultrasonic Silent Drive) ring-type motor that delivers excellent responsiveness and control. AF speed is significantly improved from the current model, and it enables accurate high-speed focus even when capturing moving subjects. When shooting with AF, the Full-time Manual Focus override allows you to instantly make fine-focusing adjustments manually, without having to switch between modes.

5. VC performance is now 4.5 stops and offers 3 modes optimized for different situations
The VC (Vibration Compensation) effectiveness is equivalent to 4.5 stops, based on image stabilization performance levels established by CIPA (Camera & Imaging Products Association) when using VC MODE 3. Model A022 now has three types of VC modes, and it is possible to choose the optimum VC mode according to the situation for taking a photograph, such as when panning.

  • VC MODE 1 is the standard mode that strikes a great balance between the stability of the viewfinder image and the stabilization effects.
  • VC MODE 2 is exclusively used for panning.
  • VC MODE 3 prioritizes the stabilization of the captured images and forgoes the stabilization of the viewfinder image.

A new VC Mode can be programmed with the optional TAMRON TAP-in Console™. You can overwrite VC Mode 1 with a new VC Mode that allows stabilization to be engaged constantly for videography purposes. In this mode, the LCD screen is used.

6. New FLEX ZOOM LOCK mechanism enables locking of the zoom ring at any position
The FLEX ZOOM LOCK mechanism quickly locks or unlocks the zoom at any position simply by sliding the zoom ring. Photographers can shoot from any angle without the zoom extending unintentionally. Additionally, the lens features the conventional Zoom Lock switch to prevent unwanted barrel extension during transportation.

7. Fluorine Coating and Moisture-Resistant Construction for a more user-friendly lens
The front surface of the lens element is coated with a protective fluorine compound that is water- and oil-repellent. The lens surface is easier to wipe clean and is less vulnerable to the damaging effects of dirt, dust, moisture and fingerprints. For greater protection when shooting outdoors, leak-proof seals throughout the lens barrel help protect your equipment.

8. Electromagnetic diaphragm system now used 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[1]. More precise diaphragm and aperture control is possible because the diaphragm blades are driven and controlled by a motor through electronic pulse signals.

9. Lightweight and easy-to-hold tripod mount is compatible with an Arca-Swiss style quick release plate
A new textured grip and Arca-Swiss style tripod interface enhances both speed and utility. And because the tripod mount is made of lightweight magnesium, it is much easier to carry.

10. Compatible with TAMRON TAP-in ConsoleTM, an optional accessory product
The optional TAP-in Console provides a USB connection to your personal computer, enabling you to easily update your lens’s firmware as well as customize features including fine adjustments to the AF and VC.

11. Teleconverters exclusively for the Tamron lens now developed
Two exclusive teleconverters[2], which perfectly match the optics of the new SP 150-600mm G2 (Model A022), offer 1.4x and 2x magnification, and provide a maximum zoom range up to 1200mm. These new teleconverters extend focal length of the master lens, making it possible to take pictures in farther ultra-telephoto ranges.

12. Based on the rigorous quality standards worthy of the SP series, this new lens is manufactured with thorough attention to details
For the SP series products in particular, Tamron has established rigorous design and quality standards. These standards apply to the optical design, mechanical design and the cosmetic appearance, as well as to such wide-ranging areas as the product’s robustness and improvements in various individual functions. Tamron thoroughly reviews of all of the design and manufacturing processes in order to offer products to customers with ever-higher precision and quality levels.

For the SP 150-600mm G2 (Model A022), the optical design was refreshed, mechanical parts were improved and a new exterior design was adopted. To maximize the optical performance intrinsic to this product, Tamron improved the accuracy of component parts and increased the precision of the overall zooming mechanism.

Design Concept
The new design adopted for the four SP series lenses already on the market is essentially the fusion of engineering and style, the pursuit of functional beauty and craftsmanship achieved by giving meticulous attention to minute details. Using metal as the exterior material creates a high-grade design based on the concept that emphasizes “Human Touch” characteristics, and significantly improves user-friendliness. The SP models feature a novel design for the switches, easy-to-read characters, an enlarged window over the distance scale and the adoption of organic forms easy for the photographer’s fingers to hold onto.

This design philosophy-the pursuit of functional beauty with a “Human Touch”-is applied even to the most minute details of the new SP 150-600mm G2 (Model A022) ultra-telephoto zoom. By using metal for the exterior material and adding new functions such as the FLEX ZOOM LOCK mechanism, the Model A022 achieves a size and weight that makes comfortable handheld shooting possible, with a slim and stylish appearance design to top it all off.
