The images below are shot using Olympus E-520 with Zuiko Digital 50-200 f2.8-3.5
Focusing was fast. Exposure is good. but the problem is i did notice the picture did came out softer than i thought i should be..if i shoot it with e3 the 50-200 will give me sharp picture ..however on e520 if give a much overall softer feel..but the pros side is the image look more natural..
Therefore i recommend +1 sharpness if using normal mode in E-520
