For a physically long lens the Tamron 180mm f/3.5 Macro balances surprisingly well on an enthusiast digital SLR like the Canon EOS 20D, or the larger, heavier EOS 5D. For handheld shooting you can shave a few ounces off its weight by removing its tripod platform, which has a hinged collar and a clever twist-and-pull locking knob.

Optically, this lens leaves little to be desired. Sharpness is great down to the diffraction limit, distortion virtually non-existent, chromatic aberrations are practically absent and flare and ghosting are very well controlled.

The Tamron AF 180mm f/3.5 SP Di LD [IF] macro offers a near-flawless performance. Optically it doesn't leave anything to be desired - the resolution is very good to excellent from f/3.5 all the way down to f/16 and vignetting, CAs and distortions are usually non-issues in field conditions. The bokeh (out-of-focus blur), a primary aspect in macro photography, is very smooth and buttery.

This lens is ergonomically well designed and handled nicely. Despite it’s capabilities, it did not weigh heavily on a neckstrap and felt comfortable and intuitive to use.
