Coming Soon: Tamron 100-400mm Super Zoom for DSLRs


For those looking to get into the super-telephoto game, Tamron has just announced the development of the 100-400mm f/4.5-6.3 Di VC USD Lens for full-frame Canon EF- and Nikon F-mount DSLRs. Packing a variety of specialized elements, including three Low Dispersion (LD), along with an eBAND Coating, this lens aims to provide aberration- and flare-free imagery throughout the impressive range. Also, Tamron has managed to keep it relatively lightweight, at less than 2.5 lb, for easier transport and less strain during shooting.

For fast-moving subjects, the 100-400mm uses a high-speed Dual Micro-Processing Unit and Ultrasonic Silent Drive autofocus system that ensures fast, responsive focusing and effective Vibration Compensation. Also, the lens can focus as close as 4.9' to achieve a maximum magnification ratio of 1:3.6 that is useful for close-up shooting. Employing magnesium in key areas of its construction, this optic is moisture resistant, as well, for use in less than ideal weather, and the front element has a fluorine coating that makes it easier to clean. Additionally, the lens is compatible with Tamron’s 1.4x Teleconverter and TAP-in Console. An optional Arca-type compatible tripod mount is available.


I had the opportunity to use this lens while visiting Santa Fe with the Tamron VIP group. The lens was tack sharp and the lightness was very comfortable indeed. I own a Canon 100-400mm L, and the sharpness of the Tamron was equal to it. If I had not previously purchased the Canon I would definitely buy the Tamron. I am even considering buying it anyway because of it's price of $799.00 compared to Canons 1899. Wish I could post some pictures to prove my point.

I have used a number of Tamron lenses over more than 30 years, mostly on Canon bodies, and unlike the critics who appear to take pleasure in finding fault, have had favorable experiences with the company and the performance and durability of the lenses.  I note that this 100-400 is intended for the full frame market, and as such is larger and heavier than it would need to be if designed for the aps-c sensors.  Rather than compete with the body manufacturers' high priced lenses— and even more demanding body-build standards— I would like to see Tamron do what Olympus has done for its smaller yet high res sensor, refine the resolution, contrast, accutance, freedom from flare, weather resistance, and near focus distance (and include a positive infinity stop) complimentary to the superior-per-area resolution opportunities offered by the 24mp sensors found in the newest Canon, Nikon, and Sony bodies.  One lens design, complimented by well made intermediate units, could be made to be useful on say, my Rebel optical viewfinder & LCD body, my M bodies, and my Sony a bodies— and would lighten the load of gear I adapt to different shooting circumstances.

Good luck! At least both Sigma and Tamron are now making lens of such quality as to rival the chilling costs of both Nikon & Canon native lens. Am using a variety of Sigma Art zooms & primes on a Canon 6D. Would greater skills than I have to extract better results.
