I downloaded the beta version of Focal for Mac to use on my MBP.
It seems to work ok on most of my Canon lenses: 35 f2, 135, 70-200 F4is, 17-55
but could not calibrate a Tamron 17-50 at all. Forgot to say, using a 7D.
I'll be using it today, coincidentally to check out a 15-85 and compare it to my sharp 17-55. If anything unusual occurs, I'll report back.
