Hi,
I´m using a Sigma 18-35 1.8 with a Metabones Speed Booster on my BMPCC.
What I noticed is that the left side of the image isn´t perfectly in focus while the right side is spot-on.
If I try to get the left side as sharp as possible, the middle of the picture and the right side will be slightly out of focus.
Please take a look at the pictures below. Notice how the very left side seems to be quite blurry, while the right side isn´t that bad. The aperture was 2.5. '> '>
I´ve tried two Sigma 18-35 and two different Speed Boosters, but the results were exactly the same.
Has anyone else noticed similar effects?
I would be very happy if someone with a Sigma 18-35 and a SB tried to shoot something outside with the lens wide open and focus set to infinity.
