I don't think a slow AF motor is a big problem with a macro lens... BTW, I'm not an expert of macro, but for the kind of macro work I've been doing in the past 18 months I doubt that one can often auto-focus a macro subject without applying manual corrections... Noisy could be a problem? Perhaps... Actually I don't know whether insects are scared by noise. The latest bug I've taken a photo at was a dwarf mantis from 30 cm, she (it was a female) was totally aware of my presence, noise or not, at the point that after a minute of staring at me she attacked the lens and was even capable of stroking the front lens with some karate-like move...
It all boils down to the image quality. I won't dare to interpret the MTF diagram as I demonstrated I'm still incapable of correctly doing that , but if it's good, it's definitely an interesting lens: compact, light and the price sounds reasonable.
