I just edited my signature and thought for a moment. I've transitioned from primes, to zooms, and seemingly, back to primes. A little more thought, no, I really loved the old MD 50mm I had, and had a hankering to get another 50mm in AF. I absolutely love it. It's sooo fun! Strangely, I can still use sensible shutter speeds, iso100 and whatever f-stop I want, even in fading light. I didn't exactly intend to go into another Primes phase, as I preferred the Minolta 28-70mm G, but the cost was slightly out of my budget, but I'm loving this 50mm phase. But I have to admit, I use the 70-300mm about as much as I do this 50mm at the moment. Hmm... just out of interest, what's everyone else's current preferences?
