This time playing with the cheap vintage 400mm that did the aggressive repair to, and checking color. Not wanting to do film, figured out how to set up on Sony. Back in the day, the lens was designed for easy transition between camera brands with a "T" adapter and I have the original Pentax screw mount, Canon FD, and Nikon F as I mated it with the three brands of film cameras I owned. For B&W used the Canon FD, so replaced it with the Nikon F and had a Nikon to Sony FE adapter to mount on the Sony. Overall, happy with short range, but focus issues intermediate and long range. On all, vignetting in corners that can easily crop out. Color? balance OK, but some purple/red fringing on some contrast levels to correct.
Next 3 days will be short range.
