Di: Digitally Integrated Design, is a designation Tamron puts on lenses featuring optical systems designed to meet the performance characteristics of digital SLR cameras.
This lens employs an IF (Internal Focusing) system that maintains the overall length of the lens during focusing. Uses two LD (Low Dispersion) glass elements that effectively compensate for Chromatic aberration. Provides high-Contrast, outstanding image quality and a soft out-of-focus background effect. Incorporates an AF/MF one touch switchover mechanism built into the focus ring(for Canon & Nikon only). Super performance series provides high performance through outstanding design specifications.
FEC (Filter Effect Control): Features the new FEC (Filter Effect Control) function that enhances operational ease of Polarizing Filter use. The new Filter Effect Control is designed to rotate the filter to the desired position while the hood is attached. This is accomplished by turning the FEC ring that in turn rotates the portion of the filter mount where the filter is mounted.
This lens is amazing, I am a commercial shooter specializing in medical, and have been a pro since 1980. My philosophy is real simple, buy the best lens for the purpose, and the money is an important part of this. This lens is sharper then the Nikkor 85 mm 2.8 shift lens, ( I have owned 2 of these lenses). Actually sharper then any Nikkor lens I have owned.

even tho this is my first macro lens, i have already taken fantastic pictures!! this lens would zoom close up into an flower, insect, or any other small things with great detail!!. i love the picture quality. i have to say though i can not compare it to other macro lens out there due to the fact this is my first one. but i could say that its is quite heavy, its long with the hood *this may be a good thing because you could get closer up without scaring the bee or butterfly away*, and the biggest problem with it is that the A-AF is really slow... like REALLY.... you must have alot of light for it to correctly focus it on something. but it dont really matter because you prob would just manual focus it because its faster and more sharp. EITHER WAY i really do love the lens!!

This is a superb lens, with a good solid build and a smooth manual focus. Because it's made from polycarbonate rather than metal, it's also surprisingly lightweight. The tripod collar is easy to remove but solid. The filter effect control is a nice convenience.
The Automatic Focus is not particularly fast, but this is not much of a disadvantage since most photographers use manual focus in macro work anyway.
