Originally posted by UncleVanya I like the perspective of the 40 on APSC - I'm honestly amazed by people who say it is awkward - older cameras often came with 58mm "normal" lenses and the 40 is roughly a 60mm equivalent which says to me people are looking for reasons to dislike it.
But going by your signature line, you're a significantly older photographer with significantly more ocular mileage who probably has a lot of working familiarity with that focal length. Others, raised on 50mm as normal, possibly find the 58mm FOV a bit "tight" in that context.
I must admit, though, it seems like a very odd focal length - significantly longer than "physiological normal (43mm)" - and sometimes I wonder if there's truth to the rumour that it was chosen because the optical-design mathematics fortuitously worked out more easily for that FL than any other.
When I first bought the DA40 Limited, I was ignorant of crop factor; I just thought it was a really neat short (in the physical sense) prime that took great photos. The more you know, the more you can get paralysed by (in)decisions sometimes.
