240 mm G-Claron for 8X10?

kcrisp · April 9, 2001

Has anyone tried an older (1967) G Claron 240mm lens with 8X10 film? If so, does it cover and is there any room for movements? Thanks.

There is a ton of lens info on this website. Check this out.

I use a 210 mm G Claron for 8x10. Although its specs would indicate

that it doesn't cover 8x10, in fact it does when stopped down to F 22

or smaller. I'm not much of a lens technical type but my

understanding is that the G Claron design is of a type that results

in gradually increasing coverage as the lens is stopped down so that

at F 22 it reaches 8x10 coverage and as you go smaller the ooverage

continues to increase so that at F 45 or 64 there's room for a good

bit of movement. I would assume the same is true of the 240 and that

it would cover 8x10 with room sto spare at smaller apertures but I

don't know for sure. I've been very pleased with the 210 - small,

light, and very sharp at least with the contact prints I make.

I have used this lens for 8x10. It covers and there is room for

limited movements. I found myself running out of image circle, so I

switched to a 270mm G-claron, which I am happier with. It has enough

coverage, and I don't mind the longer lens.
