birds with sigma 120-300mm f2.8 OS

I bought this lens 2 weeks ago. Did some test and a Micro Adjustment on 300mm at minimum focius distance. Tested the lens with some birds and came till the conclusion the les can be sharp but.....

it is not at 120mm when I do MA at 300 I know that this is impossible for a zoom lens. The MA is arround +3 and +5 so I guess +4 would be enough. But my biggest concern is that when you test at 5 meters at 120mm and 300 there is still a difference between 2 MA but it is higher, at +6 and +8. This is getting worse when you go to 10 meters away.

I will send it back this week and will see when I get it back.

so here some birdshots made with the sigma:


From my trip to Poland last week:

all EXIF is in the photo.
