negative:Build Quality
Autofocus noise (sounds like an aircraft)
comment:Wonderful colour and image quality, but the most dreadful build and autofocus. Infact, I don't use autofocus due to its noise and hunting, instead preferring manual (especially for macro). Easy to buy one without the 1:1 macro adapter, but luckily my came with it: should be easy to find a suitable adapter if it doesn't. I fully endorse buying this lens as it's fantastic for macro, but also wonderful for a portrait lens without the adapter. Incidentally, although the lens is quoted as f/3.5 on both cameras it was measured as f/3.2
