Very, very nice 10" f/6.3 Ilex-Caltar for 8x10. No mark on the lens anywhere. Coating is excellent. Had it on the 2-D this morning and it covers 8x10 with movements just fine. Shutter tested today and was smooth. Flash sync is working as it should. All speeds work and results of test are as follows:

1=.7sec
2=.4sec
5=dead on
10=dead on
25=dead on
50= 1/30
100=1/50
150=1/60

Asking $275.00 with shipping in the US/insurance included. Great little lens for 8x10. If it isn't as described, send it back to me in exactly the same shape I sent it (you pay shipping back). Retaining ring included, lens board is not.
