I purchased this lens to use with my Sony A57 (16.1 megapixel APS-C, 1.5x crop). I have three other Tamron SP lenses (A16, A005 and B01) and chose them because I felt their image quality was as good, maybe even better than the comparable Sony or Sigma lenses.

solid build, good fit & finish, very sharp at f/2.8-f/3.1 and tack sharp at f/3.5-f/16, no lateral chromatic aberration, no distortion, IF, quiet af, no front/back focus issues, smooth focus ring, moisture resistant, 6 yr warranty

a-mount connector a bit loose; sharpness declines after f/16; minor bokeh fringing from f/2.8-f/7.1; minor vignetting from f/2.8-f/3.5; lens flair; Sony version lacks VC; AF slower than expected; no case/pouch

The 90mm f/2.8 Di USD VC updates Tamron's ‘classic' 90mm macro, and comes bursting with new features. It comes in Nikon, Canon and Sony mounts and fits APS-C and full-frame D-SLRs, although the Sony version doesn't feature Vibration Compensation (VC) due to the built-in IS in Sony bodies.

Extremely sharp even when used at its maximum aperture, the Tamron SP 90mm F2.8 Di VC USD Macro 1:1 is one of the best macro lenses on the market, comfortably outperforming its legendary predecessor with the same focal length.

Handling and features Tamron's 90mm Macro lenses have earned an enviable reputation for optical quality and value for money over the years. With this new 90mm Macro optic, Tamron have brought their 90mm up to date with the latest technology by incorporating Vibration Compensation, silent internal...

This full-frame, high-speed, short telephoto is Tamron's tenth 90mm macro since 1979, but its first 1:1 close-up lens with Vibration Compensation-the only one of Tamron's five true macros to offer it.

Since 1979, Tamron has produced 90mm macro lenses whose optical quality has rivaled the extraordinary Micro-Nikkors. Some photographers claim to have preferred the Tamron over the Nikkor because of its superior handling of out-of-focus areas ("Bokeh").

I purchased this lens as I have been wanting one for a while now and have been extremely happy with it. I am yet to find anything that I am not happy with. Love the ease of use and the results I have achieved since purchasing this lens.

Tamron's 90mm macro lenses have been held in high regard by photographers for many years and the company has updated them regularly, the most recent in September 2012. While the new lens has been designed primarily for 'full frame' DSLRs, as a 'Di' lens it is also usable on cameras with APS-C sized...

The Tamron SP 90mm F/2.8 Di MACRO 1:1 VC USD is an excellent update of Tamron's very popular 90mm lens, with the new optical construction offering great image quality and lovely smooth bokeh, and the built-in image stabilisation increasing its versatility to include hand-held as well as...

I love this lens. It does everything I need it to do and never gets in my way. The lens has all the features I need and offers flawless handling. The optical performance leaves nothing to be desired.
