Originally posted by el baroda Thanks a lot for your response. I was considering getting a DA 50mm/1.8 mainly for its AF feature, but I probably don't need AF yet. I am nearly 70 but my sight and hands are still sharp and steady, respectively. Warm regards from Down Under.
I went through 73 in June, and after they operated on my cataracts, I was back to manual focusing well again. You have AF in your lens lineup - the A 50 - the only thing you would gain with the DA 55 would be SDM. Most people (other than the photographer whose ears are two inches from the lens motor) don't even notice gear drive AF.
55 is equivalent to 77, 50 is equivalent to 70, so there isn't even that much difference in perspective.
