Cheap Lens

I got a Nikon 135mm 3.5 lens for £34 on eBay. Very nice. It turned up last night and is in good condition for its age. The focus feels a bit stiff but that will loosen off as it's used. It has probably sat neglected for many years. I plan to try it on the F3 for some casual portrait work. I'm still on the lookout for a cheap 85mm or 105mm.
