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.

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.
