The few reviews online looked favorable and unlike most people, I like the effective 60mm FOV. My favorite lens for 4/3 (when I had the a full kit) was my ZD 35/3.5 macro. I'll still use this with the DMW-MA1. However, I was looking for a 'faster' native lens for m4/3. I had very few options for this focal length. Actually, I had none. The Panasonic 20/1.7 is just a bit wide...the Panasonic 14/2.5 and the Oly 17/2.8 would be even wider still. I couldn't afford the 25/1.4. I could have purchased and adapted the ZD 25/2.8 pancake, but the Sigma 30/2.8 is ideal for me. Anyway, I had a gift certificate to B&H, so I bit the bullet and just ordered it. It should arrive on Friday. I'll post pictures and a impressions when I get it.
