Yeah, It's actually quite good wide open too (or is that that what you meant seeing how WO is f/6.3?). IMHO, this model represents the best 500mm zoom one can buy for $450 ~ $500 which is what this lens often sells for in the same condition as above.
The $25 Sony-Alpha/Minolta adaptor allows aperture control on my GH1 and other M4/3 cameras too, so this guy is like an APO 240~1000mm f/5.0-6.3 when mounted on M4/3. Simply amazing resolution at that reach! I was impressed.
