These two lenses are well known for their wide coverage at small apertures.
For the purposes of contact printing, what are the image circles at different apertures for these two lenses?

If you use google and Wikipedia, the 355 should cover 20x24 so says wiki, I'm not sure that's right, or may be at 1:1, but that's what wiki says, certainly 14x17
The 450 M I've been told by a reliable well known person also covers 14x17/12x20 at f/22
Neil, I carry both with my 11x14. Both cover really well. If i had to pick one, It would be the G Claron
Depends on how you shoot, to what degree significant movements are involved. G-Claron specs were originally for process applications, not general photography. But the 355 G should be plenty versatile up thru 11x14. Using a camera point blank head-on, like for portraiture where the corners of the image don't always need
to be immaculate, is a whole different thing.
I carry both for 7x17" and have not come close to finding either's limit.
Whilst I haven't used the 450mm much, the G Claron is probably the sharpest lens that I have (all formats). I have a shot of an old pier's pillions and can see fishing line onside of these at 20-30 metres distance. Also, to my eye, there is not much apparent IQ loss on the edges of the film. Happy to produce images if required to substantiate these claims.

Both should be good for 12x20, the 355 just barely when stopped all the way down and the 450 with some wiggle room.
Yes, as Oren noted, they both cover 12 x 20.

Post #118, Sandy King has used the 450M on 20x24 stopped way down.

Thanks for the information. Let me rephrase a bit. What's the largest aperture (smallest f-stop) with either the 450M or the 355 G-Claron at which you would shoot, say 8x20, or 7x17, or 16x20, or any format with which you have experience? I'm trying to get an inkling of the apertures that tend to get used with different formats.
Wide open for both covers (i.e. usable) 7x17". Usually shot at at least f32.
