I bought my F2A new in 1979. Aside from replacing the seals two years ago, it's been an incredibly reliable piece of equipment. Electronics in the camera are limited to the metering head, which has performed without any problems over the years. I was going to say flawlessly, but I'll have to think about that.

... yes, flawlessly.

I agree that there is a huge amount of Nikon manual-focus glass available for reasonable prices.
