Product Highlights

  1. State-of-the-art optical design technology delivers superior image quality
    The advanced optical construction of this lens includes four elements of LD (Low Dispersion) glass, three Molded-Glass Aspherical elements, one Hybrid Aspherical element, one XR (Extra Refractive index) glass element, and one element of UXR (Ultra-Extra Refractive Index) glass, which has greater refractive index than XR. The full use of specialized glass elements in its design contributes to making this outstanding lens as compact and lightweight as possible, while minimizing aberrations, resulting in superior image quality. Particularly impressive is the thorough compensation of chromatic aberrations at the telephoto end, yielding images of enhanced clarity and crispness.
  2. Focus on portability – The lens is now even smaller and lighter
    In addition to state-of-the-art optical design that facilitates downsizing of the lens body, the mechanical design, which incorporates a highly sophisticated multi-stack-cam layout that takes up far less space, and PZD (Piezo Drive), an autofocus drive system with a simpler, more compact structure, has made it possible to reduce the overall dimensions of this lens compared to the existing Tamron 28-300mm (Model A20). These technologies are the fruit of Tamron’s more than 20 years of research and development in the high-power zoom lens field.
  3. Advanced anti-reflection coating
    The application of BBAR (Broad-Band Anti-Reflection) coatings for suppressing reflections on lens element surfaces minimizes unwanted flare and ghosting to deliver sharp, crisp, high-contrast images.
  4. Upgraded cosmetic design – Elegant tungsten silver brand ring
    Tamron has upgraded the cosmetic design and finish of this lens to create a more sophisticated, high-end look in keeping with the demands of discerning full-frame DSLR users. Employing a sophisticated linear pattern rubber grip on the zoom and focus rings and an elegant tungsten silver name-brand ring, this newly designed model accentuates its visceral presence with understated elegance and class.
  5. PZD (Piezo Drive) delivers faster, quieter autofocus action
    The PZD (Piezo Drive)*1, a standing-wave ultrasonic motor system, delivers faster, quieter, more precise action when the autofocus is engaged. The full-time manual focus system is easy and intuitive, enabling quick and convenient manual focus at any time.
  6. VC (Vibration Compensation)
    Tamron’s acclaimed VC (Vibration Compensation)*2mechanism reduces image blur caused by camera shake to deliver significantly sharper images even when shooting handheld.
  7. Circular diaphragm facilitates achieving spectacular blur effects
    Using a circular diaphragm*4, this lens achieves spectacular background blur effects that enable creative use of depth of field.
  8. Moisture-resistant construction for outdoor shooting
    Moisture-resistant construction helps prevent moisture from penetrating the lens.
*1 PZD (Piezo Drive) is a standing-wave type ultrasonic motor system developed by Tamron. It delivers outstanding speed and quiet operation in the AF mode. It also provides greater flexibility in design compared with ring-type ultrasonic motors, thus contributing to reduced lens size.
*2 VC (Vibration Compensation) is Tamron’s proprietary tri-axial image stabilization mechanism.
*3 The Sony mount model does not include VC, since the bodies of Sony DSLR cameras include built-in image stabilization functionality. The name of the Sony mount model is “28-300mm F/3.5-6.3 Di PZD” without the VC designation.
*4 This circular diaphragm retains a nearly circular shape even at two stops down from its maximum aperture.

Tamron Announces APS-C 16-300mm F/3.5-6.3 Di II VC PZD MACRO

February 6, 2014, Saitama, Japan – Tamron Co., Ltd. (President & CEO: Morio Ono), a leading manufacturer of precision optics, has announced the development of an advanced new all-in-one™ zoom lens exclusively for digital SLR cameras with APS-C size image sensors that provides an amazing 18.8X zoom ratio. The lens sample will be on display at the Tamron booth at the CP+ 2014, which will be held from February 13 to 16 in Yokohama, Japan.

Since the launch in 1992 of the 28-200mm (Model 71D) high-power zoom lens – which featured a revolutionary compact, lightweight design – Tamron has been continually expanding its portfolio of world-class optics to benefit consumers.

Tamron previously launched an 18-270mm (Model B008) all-in-one™zoom lens exclusively for digital SLR cameras with APS-C size image sensors that features a 15X zoom ratio, superior image quality, swift, quiet AF, and Tamron’s acclaimed VC (Vibration Compensation) mechanism, in an ultra-compact package. This ground-breaking lens has been winning plaudits throughout the world.

Responding to consumers’ demand for expanded focal lengths both at the wide-angle end of the zoom range and the telephoto end, Tamron has begun developing a completely new all-in-one™ zoom lens design that provides an impressive focal length range extending from 16mm true wide-angle to 300mm super-telephoto.

Highlights and specifications after the break

Product Highlights

  1. A further expansion of the imaging range. With a minimum focal length of 16mm (35mm film equivalent: 24.8mm) at the wide-angle end of the zoom range, and a maximum focal length of 300mm (35mm film equivalent: 465mm), this remarkable new lens provides a zoom ratio of approximately 18.8X.
    Responding to requests from consumers who wanted to be able to photograph subjects with a wider viewing angle than is possible with conventional high-power zoom lenses, Tamron has begun developing a unique lens with a minimum focal length of 16mm. At the telephoto end, the maximum focal length has been increased to an impressive 300mm. Users of this new lens can enjoy unprecedented framing flexibility by easily adjusting the angle of view using the convenient zoom ring.
  2. Superior, reliable image quality with a universal lens.
    The lens construction features 16 elements in 12 groups. This includes three Molded-Glass Aspherical elements, one Hybrid Aspherical element, two LD (Low Dispersion) elements, one XR (Extra Refractive Index) glass element, and one element of UXR (Ultra-Extra Refractive Index) glass, which has greater refractive index than XR. The full use of specialized glass elements in the design contributes to thorough compensation of optical aberrations. In addition, the use of the latest coating technology for suppressing reflections on lens element surfaces minimizes unwanted flare and ghosting and assures sharp, crisp, high-contrast images.
  3. Using a new design approach to create an ultra-compact lens.
    The latest optical technology has been used to provide an expanded zoom range (compared to the B008) at both the wide-angle and telephoto ends, without necessitating the use of an oversized lens body. By employing UXR glass (which helps to reduce the size of the front lens diameter), an optimized layout of the Molded-Glass Aspherical elements, and adopting a 5-lens-group zoom system approach to provide enhanced design flexibility, the new lens embodies the fusion of state-of-the-art optical design, sophisticated mechanical design, and high-precision lens manufacturing technology, thereby attaining a compact size, an unprecedented zoom range, and superior image quality.
  4. A minimum focusing distance of just 0.39 meters supports an extensive range of macro photography capabilities.
    The new lens provides a minimum focus distance of 0.39 m over the entire zoom range, with a maximum magnification ratio of 1:2.9. This makes it possible to get right up close to the subject of the photo to enjoy easy, stress-free macro photography.
  5. PZD (Piezo Drive) delivers faster, quieter autofocus action.
    The PZD (Piezo Drive)*1, an advanced standing-wave ultrasonic motor system, delivers faster, quieter, more precise AF action when the autofocus is engaged. There is enhanced support for contrast-detection AF capabilities, and focusing when in live-view mode has been made smoother. The new lens also features full-time manual focus, a function that was not provided by B008, making manual focusing more convenient.
  6. Sharper images with VC (Vibration Compensation).
    Tamron’s acclaimed VC (Vibration Compensation)*2 mechanism is incorporated into the new lens.*3 VC reduces image blur caused by camera shake to deliver significantly sharper images even when shooting handheld at long telephoto settings

Sigma to Add Second MTF Chart for Lenses

Sigma to Add Second MTF Chart for Lenses

Sigma Corporation of America to Release Two MTF Charts for Measurement of Lenses

Company releases the data of Geometric and Diffraction MTF charts for Global Vision Lenses

RONKONKOMA, N.Y., — February 3, 2014 – Sigma Corporation of America, a leading researcher, developer, manufacturer and service provider of some of the world’s most impressive lines of lenses, cameras and flashes, today announced that the company will now release a Geometrical MTF (Modulation Transfer Function) chart in addition to a Diffraction MTF chart when measuring the performance of all new Global Vision lenses.

MTF charts are important because they help photographers better understand the optical quality of lenses. Sigma has traditionally released Diffraction MTF data because it takes the diffraction quality of light into consideration, which can dramatically affect the data outcome. Diffracted light exists at every aperture, giving photographers a more accurate measurement of how the lens will perform in real life. Although Geometric MTF data is easier to measure and calculate since it does not consider the diffraction quality of light, it tends to show higher values in the graph and less defined results.

“As a family-owned organization, we hold ourselves and the products we design to a very high standard,” said Mark Amir-Hamzeh, president of Sigma Corporation of America. “Our customer’s expect high quality products and by sharing both MTF charts for all our new lenses, we are able to help guide them in making the most informed purchase decisions based on how our lenses will perform in actual photography situations.”

As a leader in technology and innovation, Sigma Corporation is committed to showing the true value and quality standards of all Sigma Global Vision lenses. Every lens is tested with Sigma’s proprietary modulation transfer function (MTF) “A1” measuring system before being shipped from the factory in Japan. By making both MTF charts available, Sigma is providing its customers with accurate measurements of its lenses and giving photographers a chance to see the full potential of Sigma’s lenses.

In-Depth Review: Tamron 150-600 f/5-6.3 VC

In-Depth Review: Tamron 150-600 f/5-6.3 VC

Dustin Abbott has sent us his in-depth review of Tamron’s brand new 150-600 f/5-6.3 VC super telephoto zoom lens. This lens is receiving a lot of press for it’s range and killer price of $1069 USD.

Most everyone that is reviewing lens has been giving it very good reviews. No, it’s not going to perform as well as Canon’s 200-400 f/4L IS 1.4x, but that lens costs about 10 times more!

CR’s Take
I get asked a lot about what lens to buy, and one of the most asked is what super telephoto zoom to buy. Since the announcement and reviews  of the Tamron 150-600 f/5-6.3 VC, I have had a hard time recommending Canon’s long-in-the-tooth 100-400 f/4-5.6L IS. This is a great starting point for anyone wondering if or how they’d use the super telephoto focal lengths. Some people may find they sit in the 300mm range, others may find they never leave 600mm. If you spent a year with this Tamron, you may then have a better idea as to whether or not investing in one of the big Canon L’s is the right decision for your situation and pocketbook.

I think it’s very interesting watching Sigma and Tamron release lenses that are priced extremely competitively and give wonderful bang-for-the-buck performance. Your move Canon….

Says Dustin
“I simply don’t have the budget to purchase many of the super-teles that cover this focal range, and furthermore, I don’t shoot this style of photography often enough to justify the expense even if I did.  But this lens hits a sweet spot for me.  It’s price is low enough to not only be affordable but also a small enough investment that you won’t feel like you have wasted your money if you aren’t shooting long distance every day.  So if you can’t afford a “super-tele”, how about an “ultra-tele” (that’s what Tamron is calling this lens segment)?  The preorder price in the United States is only $1069.  It is about $180 more here in Canada, but this lens represents such a tremendous value that I have had a serious conversation with a friend in the industry about how it is even possible for Tamron to make a profit at this price.  I personally wonder if they are not selling this lens at a loss to drive brand recognition.  It’s that good.”

Tamron 150-600 Shootout via LensRentals.com

Tamron 150-600 Shootout via LensRentals.com

Roger and Aaron over at LensRentals.com have completed their resolution testing of a host of supertelephoto zoom lenses. The Sigma 50-500 OS and Canon 100-400 were the two big competitors to the new Tamron 150-600 VC.

The Tamron is the least expensive of the bunch and held up very well against others in its class. While it’s not clearly the best resolving lens. The price, focal range & performance will be a big winner for a lot of people.

Summary from LensRentals.com
“My summary would be that the selection between a Tamron 150-600, Canon 100-400 IS, and Sigma 50-500 OS should be made on criteria other than MTF 50. There are some minor differences in resolution, but nothing that makes one clearly better than another. Price, weight, autofocus accuracy, effectiveness of vibration control, and a number of other factors (did I mention price?) are more important considerations when choosing among these lenses.

It’s pretty obvious that the Tamron has both 600mm range and the lowest price. These tests, and everything I see from photographers using the lens in the field, support that it’s of at least equal image quality. Some people will prefer the extra wide range of the Sigma, others the lighter weight of the Canon. But for a lot of people, the Tamron is going to be the best bang for the buck.”

Sigma 50 f/1.4 Art Lens Should be Amazing

Sigma 50 f/1.4 Art Lens Should be Amazing

Imaging-Resource sat down with Sigma at the CES show that wrapped up last week in Las Vegas to talk about the new Sigma 50mm f/1.4 Art lens they announced.

It turns out Sigma’s goal isn’t to top the Canon 50′s in performance, but to get as close as possible to the new king of resolution, the $4000 Zeiss Otus 55 f/1.4.

From Imaging-Resource
“But the most impressive information we gleaned? When discussing their goals of image quality and sharpness for the lens, Sigma mentioned they’re confident they’ll surpass competitive products from Canon and Nikon and are instead gunning for Zeiss’s new 55mm Otus lens. It’s a serious claim. The Zeiss 55mm f/1.4 Otus lens – with its $4000 price tag — is squarely aimed at high-end professional shooting such as fashion, advertising and editorial work.”

A lofty goal indeed.

Sigma Announces the 50 f/1.4 Art Lens & More

Sigma Announces the 50 f/1.4 Art Lens & More

LAS VEGAS– Jan. 6, 2014 – Sigma Corporation of America, a leading researcher, developer, manufacturer and service provider of some of the world’s most impressive lines of lenses, cameras and flashes, today announced the launch of two new Global Vision lenses from the 2014 Consumer Electronics Show in Las Vegas.

The improved and redesigned 18-200mm F3.5-6.3 DC Macro OS HSM and 50mm F1.4 DG HSM lenses are the latest additions to Sigma’s Global Vision lineup. Both lenses’ availability and pricing have yet to be announced.

“These two lenses are among our most popular, and we’re pleased to reintroduce these products by adding them to our Global Vision lineup,” said Mark Amir-Hamzeh, president of Sigma Corporation of America. “The 18-200mm, in particular, is an exciting new lens as it now has macro functionality, updated optics and a Global Vision design, making it a fantastic alternative to the kit lens. As has been the case with our recent Global Vision lenses, we expect an array of photographers to gravitate to their technically advanced features and slick new look.”

The 18-200mm F3.5-6.3 DC Macro OS HSM Contemporary lens, designed specifically for APS-C DSLRs, is the successor to the 18-200mm F3.5-6.3 II DC OS HSM, which was launched in 2011. The smaller and lighter lens (15.2 ounces and 2.8×3.4 inches versus 17.3 ounces and 3×3.5 inches) now macro capabilities with a minimum focusing distance of 15.4 inches and a maximum magnification ratio of 1:3, as opposed to the lens’ earlier minimum focusing distance of 17.7 inches and max magnification ratio of 1:3.8. Its minimum working distance is 14.7 inches, which makes the lens suitable for close-up shooting with natural light, keeping shadows of the camera and lens out of the image.

The 18-200mm F3.5-6.3 Macro has also been updated to incorporate Special Low Dispersion (SLD) glass elements that have a high refractive index and can correct chromatic aberration at the telephoto-end. Moreover, aspherical lens elements, including double-sided aspherical lenses, will ensure a compact size and excellent correction of distortion.

The new Sigma 50mm F1.4 DG HSM Art has been reengineered and redesigned to set a new standard of performance in the Art line. A staple focal length, the new Sigma 50mm F1.4 Art is a pro level performer for full-frame DSLRs great for many different types of photography including portraits, landscapes, studio work and still-life. It has been updated to include SLD glass and optimized for rich peripheral brightness with improved large aperture performance by positioning wide elements into the front groups. Other updates include an optimized autofocus algorithm for smoother focusing and a floating focusing system to reduce lens movement while focusing. Under the Global Vision line, it features a new matte finish, improved AF on/off switch and guarantees every lens is tested with Sigma’s proprietary modulation transfer function (MTF) “A1” measuring system before being shipped. Now with 13 elements in 8 groups compared to the previous 8 elements in 6 groups, it also has improved close focusing at 15.7 inches and a maximum magnification ratio of 1:5.6

Both lenses incorporate Sigma’s Hyper Sonic Motor (HSM) system to produce quiet, high-speed auto focus. In addition, they include Super Multi-Layer Coating to reduce flare and ghosting, and to ensure high-quality images throughout the entire zoom range. The 18-200mm F3.5-6.3 DC Macro OS HSM and 50mm F1.4 DG HSM lenses are also compatible with Sigma’s USB dock and the company’s Mount Conversion Service.

Other recently announced lenses and accessories such as the 24-105mm F4 DG OS HSM, 18-35mm F1.8 DC HSM | ART and USB Dock will be on display at Sigma’s CES booth. Visit Sigma at CES 2014 at booth 10431in Central Hall at the Las Vegas Convention Center from Jan. 7 to 10.

Rumor: Sigma 16-20 f/2 DG Art [CR1]

Rumor: Sigma 16-20 f/2 DG Art [CR1]

Sigma 16-20 f/2 DG Art for full frame
A rumor has surfaced talking about the possibility of a  Sigma 16-20 f/2 DG Art series lens for full frame cameras. We had previously heard about Sigma working on a 24-70 f/2 DG Art lens for full frame cameras, but nothing else has been mentioned about it in a while.

CR’s Take
Possibility of this? I’m not sure, that’s a very short zoom range. I think something like 16-24 would be better and put real pressure on both Canon and Nikon (the Nikon 14-24 is terrific and expensive).
