I am considering the Nikkor 1200 T. However, I have heard very mixed reviews. The lens tests performed by C Perez shows the Nikor 800 T to perform poorly in resolution test. (This tends to be true with must teles vs. non teles of the same fl, that's one of the trade offs for the Tele's reduced extension) I would assume the 1200 T would perform the same or slightly worse, but not better. at 40 lpmm to film, it would suffice on 8x10, but I had planned to use it on 4x5 more often. I am also concerned about camera shake with 775mm of extension and such a long focal lenght... I can not find this lens at rental houses to test. Any input would be very helpful. thank you...

Mamameea.... I use the Nikkor T 720mm and my yeilds are about 50%. Camera vibration is a biggy. Depth of focus is another. I always shoot at f64. If you talk with a Nikon representative he will tell you the lenses are optiomize for infinity. Any thing shorter or longer than that will be soft. When I get everything right I have found the lens to be razor sharp. To be truthful with you Bill I would say using the 1200mm lens is beyond my abilities. Good luck!
