PETE - Nikon/Sony Shooter
Finally got my custom ext tube back from my engineer pal, and have already flocked the inside.
In the non CPU lens data of my Nikon D300, there is no option to set 700mm focal length on manual lenses. I could either have 600mm or 800mm. So i set it for both and took 2 identical shots.
For the 600mm focal length, i chose f6.3 aperture in the set up, and for the 800mm focal length i chose the f7.1 aperture, to see which came out best.
The 200mm ext tube with Nikon F mount grafted on ( using tapped threads and 2mm stainless steel counter-sunk machine screws )
