THE NEW XCD 3,5-4,5/35-75 – PRIME LENS PERFORMANCE IN A COMPACT ZOOM

The ninth addition to the X System lens range is the eagerly awaited XCD 3,5-4,5/35-75 Zoom Lens. Delivering the same superb image quality from edge-to-edge as the XCD prime lenses, this extremely high performance, compact mid-range zoom covers moderate wide angle to short telephoto focal lengths. Its internal focusing keeps the lens’ dimensions constant, delivers quick autofocus and additionally keeps the overall weight down. Ideal for shooting anything from wide angle landscapes to portrait images, this lens is perfect for photographers who are looking to keep the amount of equipment they carry when travelling to a minimum but don’t want to compromise on image quality. “This really is the best lens Hasselblad has developed – its performance is extremely high, competing with our prime lenses. I can even go as far to say that it’s probably the best zoom lens currently available on the market,” says Per Nordlund, Hasselblad Lead Optical Designer.

Like the rest of the XCD lens range, the XCD 35-75 features an integral central lens shutter, offering exposure times from 68 minutes to 1/2000s with full flash synchronisation throughout.

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

09 Feb

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.

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

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. 

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

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″).

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

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.

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

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. 

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

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. 

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

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).

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

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.

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

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.

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

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 70-200mm F2.8 and 10-24mm F3.5-4.5 updates

07 Feb

$ (document).ready(function() { SampleGalleryV2({“containerId”:”embeddedSampleGallery_8028434815″,”galleryId”:”8028434815″,”isEmbeddedWidget”:true,”standalone”:false,”selectedImageIndex”:0,”startInCommentsView”:false,”isMobile”:false}) });

Tamron has announced updates to two of its zoom lenses. The full-frame Tamron SP 70-200mm F2.8 Di VC USD G2 improves on its predecessor with faster autofocus and better stabilization. Tamron claims its boosted Vibration Correction provides 5 stops of stabilization. The lens is moisture and dust-resistant, and has received a thorough overhaul of optical and mechanical designs. The new optical design consists of 23 elements in 17 groups, and includes extra low dispersion and low dispersion elements to reduce chromatic aberrations. Tamron claims the inclusion of two microcomputers and a new AF algorithm has improved focus speed and accuracy. Minimum focus distance is also improved, reduced to 37.4in from the previous model’s 50.7in. The 70-200 also supports Tamron’s 1.4x and 2x teleconverters/

Meanwhile, the Tamron 10-24mm F3.5-4.5 Di II VC HLD adds stabilization and refined optics to the company’s wide-angle zoom for APS-C introduced in 2008. It features LD, XLD, aspherical and hybrid aspherical elements, as well as a Broad-Band Anti-Reflection coating. Tamron was able to add Vibration Correction without increasing the size of the lens, and the company claims up to 4 stops of shake reduction. It also uses a new HLD (high/low torque-modulated drive) motor that allow for smooth control over the lens’ heavy elements. The lens is sealed against moisture and has a fluorine coating to keep oil and water off of the front elements.

Both of the new lenses use electromagnetic diaphragm control on Nikon mounts.

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.

Press releases:

TAMRON REDEFINES THE FAST TELEPHOTO ZOOM CATEGORY WITH THE INTRODUCTION OF THE NEXT GENERATION 70-200MM F/2.8 ZOOM

All-new optical design delivers a dramatically faster autofocus speed and image stabilization performance of 5 stops

SP 70-200mm F/2.8 Di VC USD G2 (Model A025) 

February 6, 2017, Commack, NY – Tamron, a leading manufacturer of optics for diverse applications, announces the launch of SP 70-200mm F/2.8 Di VC USD G2 (Model A025), a new telephoto zoom lens product for full-frame and APS-C DSLR cameras. Model A025 was developed by substantially enhancing the features of its predecessor.

These include a thorough review of the optical, mechanical and electronic designs to increase autofocus speed and precision, reinforce VC (Vibration Compensation) functions and to shorten the MOD. New features include eBAND Coating, Moisture-Proof and Dust-Resistant Construction, Fluorine Coating and compatibility with teleconverters. The lens design features a metal-based barrel for improved handling and ease-of-use. The result of this dramatic evolution is Model A025, a high-speed telephoto lens that widens the scope of expression for photography in a broad range of genres, such as portraits, landscapes, sports and photojournalism. The lens is expected to be available in the U.S. in March at $ 1299.

PRODUCT HIGHLIGHTS 

  1. Outstanding resolution and contrast reproduction performance, beautiful bokeh and full compatibility with Tamron teleconverters

Based on the current model (A009), the optical design has been revised and improved. Both the resolution and contrast reproduction performance far exceed the present levels. Bokeh has been enhanced and expanded to deliver outstanding background effects across the entire zoom range. Use of a circular diaphragm with nine blades further improves bokeh. The optical design of the new A025 consists of 23 elements in 17 groups. Optimum deployment of XLD (eXtra Low Dispersion) and LD (Low Dispersion) glass elements thoroughly eliminate chromatic aberrations, which tend to become particularly prominent in high-speed telephoto lenses, across the entire zoom range, while ensuring uniform, high-level image quality even on the periphery of the image plane.

The new lens is also fully compatible with the TELECONVERTER 1.4x (Model TC-X14) and TELECONVERTER 2.0x (Model TC-X20)1, which increase the focal length of the lens to 1.4 times and 2 times the original, respectively. Both teleconverters are carefully designed and constructed to provide outstanding high quality.

  1. Improved VC system provides highest Vibration Compensation ability in its class3 (5 stops using CIPA standard compliant) and offers three situation-specific VC modes

Utilizing Tamron’s original VC (Vibration Compensation) system, which uses a moving coil mechanism, further reinforcement of the drive system power and control performance has now achieved the highest VC level in its class, with an image stabilization performance of 5 stops according to the CIPA standard (using VC Mode 3). 

Also, the VC system of Model A025 offers three VC modes, including one mode exclusively for panning. Photographers can freely choose between the different VC modes according to their shooting conditions. Even when telephoto shooting in low light, which tends to be severely affected by camera shake, photographers can now enjoy jitter-free handheld shooting with much greater flexibility. 

  • 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.

With the optional accessory TAMRON TAP-in ConsoleTM, you can customize the configuration of VC MODE 1. Choose the viewfinder view of either standard or image priority.

  1. Demonstratively improved autofocus speed and responsiveness

Model A025 is equipped with a USD (Ultrasonic Silent Drive) ring-type ultrasonic motor, whose outstanding responsiveness and control ensures accurate high-speed focusing. Incorporating two advanced, high-performance microcomputers and optimizing the algorithm has improved both the focusing speed and accuracy compared with SP 70-200mm (Model A009). Additionally, thanks to the Full-time Manual Focus override mechanism, photographers shooting with AF can instantaneously make fine focusing adjustments using MF without wasting time by switching the AF-MF mode back and forth.

  1. Focuses closer (shorter Minimum Object Distance, or MOD) for greater versatility

Improvements made to the focus cam and zoom cam inside the lens barrel have reduced the MOD from 50.7 inches in the older Model A009 to 37.4 inches for Model A025, which has a maximum magnification ratio of 1:6.1. The shorter MOD, coupled with the excellent optical performance of the SP 70-200mm (Model A025), allows photographers to further broaden their range of expression.

  1. Optimized and exclusively designed eBAND Coating

The new A025 features Tamron’s original eBAND (Extended Bandwidth & Angular-Dependency) Coating, a technology that combines a nano-structured layer with an extremely low refractive index with the conventional multiple-layer coatings. Optimized and exclusively designed for this new zoom, the eBAND Coating provides superior anti-reflection performance, effectively reducing any flare and ghosting. Even when taking backlit portraits, the new lens delivers flawless, crystal clear images. 

  1. Moisture-Proof and Dust-Resistant Construction

Ideal for use in outdoor photography, the new 70-200mm telephoto zoom has moisture-resistant construction because special sealants that are dust-resistant and moisture-resistant are used at every joint and seam. The sealant material helps to prevent the intrusion of any dirt, dust or water droplets, compared to conventional Moisture-Resistant Construction. 

  1. Fluorine Coating for greater protection

The front surface of the lens element is coated with a protective fluorine compound that is water- and oil-repellant. The lens surface is easier to wipe clean and less vulnerable to the damaging effects of dirt, dust, moisture and fingerprints.

  1. 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 available for Nikon-mount lenses4. More precise diaphragm and aperture control is possible because the diaphragm blades are driven and controlled by the motor through electronic pulse signals.

  1. Lightweight and easy-to-hold tripod mount is compatible with Arca-Swiss style quick release plates

A new textured grip and Arca-Swiss style tripod interface enhances both speed and utility. Because the tripod mount is made of lightweight magnesium, it is much easier to carry.

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

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

  1. Based on the rigorous quality standards worthy of the SP series, this new lens is manufactured with a 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 the various individual functions. Tamron thoroughly reviews all of the design and manufacturing processes in order to offer products to customers with even-higher levels of precision and quality.

For the SP 70-200mm G2 (Model A025), 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 the component parts and increased the precision of the overall zooming mechanism.

TAMRON INTRODUCES ULTRA-WIDEANGLE ZOOM WITH VIBRATION COMPENSATION

Compact, high-performance lens boasts the largest focal length range in its class

10-24mm F/3.5-4.5 Di II VC HLD (Model B023) 

February 6, 2017, Commack, NY – Tamron, a leading manufacturer of optics for diverse applications, announces the launch of 10-24mm F/3.5-4.5 Di II VC HLD (Model B023), a new ultra-wideangle zoom lens for APS-C DSLR cameras. The lens is expected to be available in the U.S. this Spring at $ 499.

Model B023 is a wideangle zoom lens that covers an exceptionally large range—the largest focal length range in its class1 (35mm equivalent is 16mm to 37mm). The lens is ideal for street photography, landscapes, group photos and casual everyday scenes. In 2008, Tamron launched the SP AF 10-24mm F/3.5-4.5 Di II LD Aspherical [IF] (Model B001) that provided an unprecedented focal length range in its class. Building on that lens’s popularity, the successor Model B023 has improved optical performance and new features. It embodies Tamron’s most advanced technologies, including the VC (Vibration Compensation) system, Moisture-Resistant Construction and Fluorine Coating, and the first implementation of Tamron’s new HLD (High/Low torque modulated Drive). Additionally, the Model B023 has a refreshing new design derived from the design of the new product lineup in the SP series.

PRODUCT HIGHLIGHTS 

  1. Inheriting the broadest focal length range in its class of ultra-wideangle zoom lenses

The new Model B023 achieves a broad focal length range of 10-24mm, the largest range among ultra-wideangle zoom lenses for APS-C DSLR cameras. This is the 35mm equivalent of covering a very wideangle of view, from 16mm ultra-wideangle to 37mm semi-wideangle. A photographer can enjoy diverse wideangle expressions with just this one lens, from dynamic landscapes far beyond the normal human field of vision to simple, casual snapshots. 

  1. Improved optical performance across the entire zoom range

The optical design of the new Model B023 consists of 16 lens elements in 11 groups. Special lens elements are utilized in an optimum configuration of one LD (Low Dispersion) lens element, one XLD glass element, one molded glass aspherical element, and one hybrid aspherical lens. While curbing an increase in the size of the optical system, the new lens very effectively compensates for a wide variety of aberrations in the entire zoom range, including transverse chromatic aberration, comatic aberration and distortions that tend to become more prominent with a wideangle lens.

Tamron’s highly regarded BBAR (Broad-Band Anti-Reflection) Coating and the optical design paying close attention to internal reflections in the lens barrel also curb the effects of harmful light rays that tend to occur with a wideangle lens, achieving excellent resistance against ghosting and flare seen in backlighting situations.

  1. 4-Stop Vibration Compensation that is especially useful in low light conditions

In response to the requests of many customers who have asked the company to equip a wideangle lens with image stabilization, we have now installed Tamron’s acclaimed VC (Vibration Compensation) on the new Model B023. Optimizing the actuator and the control algorithm has made it possible to incorporate the VC, while maintaining the compact design of the previous Model B001. The VC especially enhances the photographer’s freedom in handheld shooting at dusk or in a dimly lit room, and under other relatively low light conditions, as the mechanism proves particularly effective in the shooting conditions with slower shutter speeds.

  1. Equipped for the first time with the new HLD with outstanding driving power and stability

Tamron’s new HLD (High/Low torque modulated Drive) has been developed for use as the AF drive system for Model B023. With its outstanding driving power and stability, the HLD is capable of smoothly controlling the AF mechanism of the new Model B023 that is actually equipped with large focusing lens elements. When shooting in AF mode, the Full-time Manual Focus override allows you to instantly make fine focusing adjustments manually, without having to switch between modes.

  1. Compressed into a compact body with structural ingenuity

While enhancing image quality, adding new functions and substantially improving the basic performance, Model B023’s space-saving design has ensured an optimum configuration for components such as the VC and AF unit, thus successfully reducing overall length compared to the previous Model B001. The lightweight and compact body with outstanding ease of use will prove to be very well-balanced when attached to an APS-C DSLR camera.

  1. An even more user-friendly lens with Fluorine Coating and Moisture-Resistant Construction

The front surface of the foremost lens element is coated with a protective fluorine compound that is water- and oil-repellant. The lens surface is easier to wipe clean and is less vulnerable to the damaging effects of dirt, dust, moisture and fingerprints, allowing for much easier maintenance. For greater protection when shooting outdoors, leak-proof seals throughout the lens barrel help protect your equipment.

  1. 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 lenses2. More precise diaphragm and aperture control is possible because the diaphragm blades are driven and controlled by a motor through electronic pulse signals.

  1. 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.

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

While inheriting the design that makes use of a lot of organic curves and the delicately polished form down to fine details that characterize the SP lens series, the new Model B023 comes with a highly sophisticated design that also places much 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, the switch shape and the distance-scale window design.
