Bob,

Just keep showing us these photos. They are always great. TS lenses  
take some playing with as you know. I have the Nikon 85mm which goes  
to f45. It's still sharp there. Prior to my getting the D700 I used  
it on my 1DS MK II. It works like a champ. Now I want to get Nikon's  
24mm. Unfortunately I don't think it will work on the Canon because  
of their new E aperture  control which needs power from the camera  
body. I wish they didn't do that. You don't need speed with a TS  
system. It's for slow working, precise photographers.

I love your bird photos by the way.
Best,
Len
