If you look at the pic at 100%, there seemed to be radial out of focus zones. For example, place an imaginary donut on the image. The part covered by the donut are soft and other parts sharp. So working your way out from the center, it starts out sharp, then soft, then sharp again, fnishing with soft corners.

I noticed that too.

Hi Jared and Dan, Here is my challenge: three similar shots one with Speed Booster, another one with regular high-quality adapter, and one with a special adapter containing a glass element.

Can you detect the phenomenon on any of them?

Take care and thank You, Miki

Miki,

thanks for posting this comparison. The slightly blurry edges in #3 (Speedbooster) don't bother me at all as I've seen worse with prime lenses on FF or APS-C in combination with respective normal (glassless) adapters.

Same for me Michael.  Thanks Miki.
