The 135 Hektor in short mount works well; the 125 Hektor is a little 
bit iffy in the corners. Fairly severe light falloff at wider 
apertures and also not that sharp. Things are OK by f/8. I haven't 
had this lens for 30 years or so, and I'm going by memory, so you 
might want to try it yourself. :-)

I forget which 200 works better, but I seem to recall that the older 
280/4.8 worked better on 6x6 than the later one. Again, time and that 
memory thing...
