Upload & Sell: Off
Godfather - you are brilliant! I put the original foot back on and it had slightly shorter screws and eureka, it turns!
Jason - Nope, kind of out of my price range. How about when you are ready to sell one of yours at a good discount you let me know? I am going back to Kenya with a side trip to Rwanda for gorillas this June so thinking maybe I might rent a 1dx to go with the 1d4 & 5d3.
Dolina - I had taken the CR-80 off the 800mm just to go try, but it is not ideal (beyond the too long screw issue). One of the things I have noticed is with the lens back weighted I think I will go with new 4th generations foot since you can adjust the weight back of where the foot attaches to the lens. With the CR-80 it was balanced if I put the back of the lens plate at the very end of the wimberley plate to were you couldn't scoot up the any further and then if I added an extender it wouldn't balance on the wimberley unless I kept tension on it, otherwise it would point to the sky. I don't buy RRS, but even if I did it seems like all the weight is in front of where it attaches to the lens so I can't see how you would get proper balance. Greg at Naturescapes is supposed to get one in this coming week, not sure what it is going to look like - if it variable like 4th generation I might try, but I am on the waitlist for the 4th generation to come back into stock. Spoke to him on Friday and they should be back in stock in a few weeks.
Guys - thanks for all the help and so glad I don't have to send my new baby to canon tomorrow!
