Re: Speed-booster causing strange defocused zones?

I tried out this combo with this sample pic from my short break from work. Barrel distortion is minimal to almost none IMHO. C&C are welcome. Thanks

f/8

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.

Anyone else notice this? It's not the first time I've noticed this strange behavior with speed-booster samples.

I noticed that too.  Not sure this happens to all Speed Booster adapters or mine is not normal.  Probably do a few tests soon to find out.  Thanks
