Interesting. When will we get to peek on the original sized files?
I switched it on a few min ago
They already tested it on EPZ and it wasn't very good, I wonder what you will find out...
The odd thing is ... the results are consistent when using it from a tripod (thus I got the MTFs and they are Ok).
However, when using it handheld with activated AF, some images show a clear deterioration on the lower left.
I'm slightly wondering now.
Is this a centering defect ?
Or does it relate to using this lens on an Olympus camera where the IS is deactivated ... thus maybe not properly "locked" ?
There's no mechanical switch for the IS after all.
Looks like a broken/loose screw inside the lens had a similar problem, the lens was easily repaired, the lens could have been good when manufactured, such things can happen during shipping/use
As you can see in the picture below depending on the loose/broken screw you can have any kind of image deterioration.
Most likely there's a loose element - which doesn't overly matter on a tripod but handheld it is a problem.
Yep exactly and since it's a mirrorless camera that uses the sensor itself to focus you have no focus issues, the camera will select the area where the picture is sharpest, with a DSLR expect things to be worst with erratic focus added.
