Sigma 150mm f2.8 macro lens with Olympus E-series

[bushman46]

Hi

Has anyone here used the Sigma 150mm f2.8 macro lens with an Olympus E-series (four-thirds) dslr, especially the E-510? If so, what is your opinion about the lens - IQ, build quality, reliability, AF speed, low light performance, ease of carrying around on/off the camera, etc? Would appreciate some feedback. Currently have the Olympus Zuiko 50mm f2, which is a great lens, but is not really 1:1.

Thanks

I hear it's very nice and the pictures I've seen from them look good but I think it's usually the Nikon mount version I've seen used (not that it'll make much odds!).

I've never used any of the Sigma macro lenses myself but from what I hear the AF isn't very quick. The closest thing I've tried is the Canon 180mm macro and would describe the AF speed as 'amusing'. I cetrainly wouldn't describe it as quick nor have I heard of anyone describing a long macro lens as having quick AF. Accurate maybe, quick no!

PS by long macro lens I mean 150mm+. Canon and Nikon do some shorter macro lenses that still have pretty quick AF but I don't know about Olympus I'm afraid. AF is no real use for macro anyway
