The focal length of the Series II, No. 5 is 9 7/8" (250mm). It is not recommended for 8" X 10". The maker stated that at "medium stop" (f16 maybe) it would cover 7" X 9" or 5" X 8" wide open. The Series III, in addition to being a little slower, worked at a wider angle - up to about 90 degrees. It is also, of course, a little smaller and lighter and, when new, was a few dollarsl ess expensive.
