I have a Nikkor 50mm f/1.8D that I bought for about $100 five or so years ago to use with my D50. I recently bought a D3200, though, so the old D lens is now a manual focus. Should I bother getting the G version just for the autofocus? In exchange, I'd be giving up the ability to stop down to f/22 (the G only goes to f/16). I haven't used my nifty fifty in a long while, but I recently bought the 35mm f/1.8G and I love it, and have decided to shoot with primes only for a while. It's not like it's an expensive lens to buy, but $200 is $200, money I could put towards am 85mm or something else.
