How's Your 75/1.8 Oly Wide Open?
I've had my black version for a few days now shooting with my GH-2. Wide open it has just a hint of CA in the RW2 files that is easy to correct. The excellent wide open sharpness improves only slightly stopping down.
I find that mine appears to be slightly decentered as the top left corner is just slightly less sharp than the others - though this could be the mount on my GH-2 I suppose. I may replace it with another copy since I plan on using it for landscapes and corner sharpness matters to me.Up close wide open it seems slightly less sharp than at distance, but it's still very very very good.
It has made me wish for IBIS on my GH-2, hence a black GX7 may be in my future if I dare order one from Canada.
What's your experience been?
