Well... I went and bought FoCal today. Previously I had set up a test rig for my 100-400L and after a fair amout of set up and testing I determined I needed a +5 at 400mm (unfortunatly I put all this effort into figuring out a testing scheme before John published his set up
). So that lens was the one I started with when I got the FoCal loaded up. I did the fully automated test and it came up with a +5 adjustment (and it repeated several times). So it looks like it worked well on that.
I did 3 other lenses today also, and the big supprise was my 100mm L Macro... it showed it needed a +19 (very supprised). I think I need to do some more testing up close to see if that still holds true with less than a foot focus depth. I have some real sharp photos up close and I do not want to screw that up.
Edit:
By the way, the lighting does matter. I ended up putting a couple halegen lights from the garage on the target, and that worked fine.
