Kerry Thalmann calls it one of the "future classics". You can read about it on his web site, but I've copied what he has to say:
"240mm f9 Fujinon A (245g, 52mm, 336mm) -
This, my friends, is an absolutely amazing gem of a little lens. It's the longest non-telephoto focal length ever offered in a #0 shutter, yet it can hit the corners of 8x10 with a little to spare. As an APO process type plasmat, performance, as you would expect, at close distances is outstanding. I have also used this lens extensively for distant subjects, and it is also an excellent performer for that application. Although, it is a stop slower than the 210mm f5.6 plasmats, for hiking and backpacking, I greatly prefer it due to its compact size, light weight and smaller filter size. Unfortunately, Fuji decided to discontinue this little beauty during the summer of 1998. As of this writing, there are still a VERY limited number of new samples available from existing dealer stock. If you're lucky enough to find one, I recommend snapping it up. If not, they should be available occasionally on the used market."
You're lucky to have found one..........
