Many thanks
No it is actually a F6.3 lens, next stop down if F8 and so on. It does seem to be an unusual f ratio lens. Its "Flexar" brand, and I got it from Ebay from QLD for $130. Its a good lens though shows some purple haloes around stars (chromatic abberation) when iused for astrophotography. It has front elements and 2 more small ones at the rear (field flattener I think)
