Thanks Leonard. I appreciate the comment. I'll keep practicing and showing.
As for stopping down, I?definitely need to do more of it. Lesson learned 
with this outing.
I've found that TS is always a compromise?of chosing what you want to be the 
sharpest. The liveview really?helps as with my camera you can magnify 
the?scene and really check out what's in focus and what's not.
The biggest problem is I tend to put the camera down very low. After 
about?10 minutes, I don't?feel my legs anymore!?:-)
Thanks again,
Bob

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
