I have two questions about the 11x14 format. First,what is the minimum amount of image cirlce to cover this format with little movement. And which of these len' s would be able to cover this format with moderate movements if stopped down to f45 or f64? Caltar-S II 300mm f5.6, Rodenstock 480 mm Ronar,and Rodenstock Roag on 360mm f6.8(enlarging lens). I could not find information in the previous thre ads. Thanks for any feed back you can help me with.

Diagonal with a Fidelity 11x14 holder is 443mm. Sorry I can't help with the lens part of your query. Unless the mfr. claims a lens has enough coverage it's hard to know if a given lens will cover a particular format unless you actually try the lens on that format or the next larger format.

Note, though, that "moderate movements" require a lot more inches in 11x14 than they do in 4x5; assuming it means 110-120% of the diagonal, in 11x14 that's 487-532mm (did I mention that I have for sale a 210SA with a 500mm image circle?). It's also not ideal to stop down to f45 or f64 all the time, but I'm guessing that you probably knew that already.

Take a look at the following site: http://www.bostick-sullivan.com/Alt_cameras/large%20format%20lenses.ht m

You will find a list of lenses that cover the format with an image circle of at least 452mm. The lenses you list may be included in the table, particularly section 2 which covers modern lenses.

By the way, are you looking for a lens that will cover 11x14 or are you trying to determine whether your current lenses will work?

Hi Dan,

None of your three lenses will cover 11x14 at infinity with moderate movements. Rodagon might just cover the format at f45 without movement. But they all should cover 11x14 at 1:1. Are you looking for lenses which cover 11x14 at infinity? Cheers,

Thanks for all your help. From the answers of Micah,Dave and Geoffrey I came to the conclusion my three lenes I mentioned will not cover 11x14. Dave, thanks loads for the lens url. Micah, I need a wheel barrel to carry around my 165 s/a and the 210 s/a is a beautiful 100 degree w/a like the 165 but with 500mm of i/c yet its twice the size. I will be looking for an older barrel lens or a copy lens like a 355 G Clairon. I am looking to go into an 11x14 format for contact printing only in the alternative process, palladium and platinum.

The 355 G Claron has a good reputation but I seldom see one for less than $1,000. When I started with 11x14, I bought a 19" Goerz Red Dot Artar. The Red Dot Artar enjoys a similar following but is often available in a barrel mount for under $500. I've even seen a 24" Artar without stops for around $100. Considering the cost of a new fidelity holder or a custom made one from Wisner, AWB, Great Basin, etc., the Artars are quite a bargain. Good luck with 11x14!

Speaking of 19" RD Artars, I picked one up on eBay for $163, delivered. Still need to get it mounted in shutter, but that'll happen one of these days.
