Hello zoners,
I received my 45-200 yesterday knowing fully it's not the greatest lens ever but that it can produce decent results when used with care and I intend to take it along to my scotland trip next month.MUDGES.
Still, I'm not entirely convinced about it with regard to its output.
I find that CA are a bit too much although I know that most reviews were on G1 and its CA auto correction. Something lacking on my E-P1. And I find it quite soft too, not really comparing well to PZone samples.
I don't think there are many mFT shooters around PZone, and probably even less with a 45-200 but I wanted to ask if anybody could relate to the following :
-It needs extremely high shutter speeds at 200mm, something like 1/800s @200mm with mega OIS activated and clearly active on the lcd. I'm aware that the arm heavy holding position of the E-P1 (away from the body) makes it less stable than the typical holding position but it seems to me rather incredible to be this sensible.
-strong exposure shifts while changing the aperture. I've tested the DOF preview to check if the aperture had any problem, it seems it's moving properly on every 1/3 of a stop. It seems partly due to the vignetting correcting itself from wide open to one stop down, but could it make such a difference?
-doesn't seem to be improving at all when stopping down on longer focal lengths, confirmed by Klaus' test.
-the obligatory "full size samples check" : would you rate these acceptable?
All unprocessed RAW from LR3 converted to JPEG 90% quality, 200mm @f/5.6

Here's the same with some edits.I added a hint of sharpness and tried to suppress (slider set to -75 on the Blue/Yellow slider, didn't need to touch red/cyan, surprisingly) on the 7 & 10.
