Real Quick...am designing an 11x14 horizontal enlarger and will need a lens for this. Preferably something slightly "wide" so that I can project to reasonable sizes (30x40 to 40x60-ish) within the confines of a 15'x16' room.

My 305 G-Claron has been working fine for making images with the 11x14 - but I'm not sure about its appropriateness for making enlargements from this format.

I'm thinking that something around 14 to 18 inches would work...but if anyone with some real-world experience could chime in - I'm all ears!
