I know tha 300mm is considered a normal for 8x10. But does any 300 cover 8x10. I have a Symmar convertible that i use for 4x5, will the 315 cover 8x10? Thanks for the help, from this hopeless weekend warrior.

Tim,

Many modern 300mm lenses cover the 8x10 format (when focused at infinity and stopped down to f/22) with at least some minimum room for movement. Look at the lists on the main page of this bulletin board for listings and ratings. My 300mm is the 300mm f/9 M-Nikkor and I would characterize it as sharp and small; physically it is the smallest lens I carry. I would recommend it over your convertible Symmar if you feel the urge to switch. As to whether your lens covers 8x10, if it is not listed in the lists mentioned above, there is always the acid test: mount one on an 8x10 camera and try it.

Look at the lens specifications listed in this web page. I believe you need a minimum of 325 mm for 8 x 10. Movements are limited by how much coverage over the minimum you have. Not all 300 mm's, however, cover the 8 x 10 format. The lens design is the most important criteria.

Any Rodenstock Apo Sironar-S 210mm and longer will more than cover 8x10. Any Rodenstock Apo Sironar-N 240mm and longer will more than cover 8x1

I have a fuji 300mm f8.5. More than covers 8x10. Uses a 52mm filter too...very light and compact.
