The 240mm f9 Fujinon A is a great lens that I recommend for 4x5 or 5x7 use, but I don't think the coverage is sufficient for general purpose 8x10 use.

For this reason, I do not recommend the 240mm f9 Fujinon A for 8x10 use. If weight is a concern, the 240mm f9 Germinar-W is a much better choice. If weight isn't a concern, as previously mentioned, the 240mm APO Sironar-S would be my first choice, but any of the multicoated 240mm f5.6 plasmats made in the last 30 years would be better than the 240mm Fujinon A.
