Originally posted by jtkratzer I looked at the crop factor making the DA15 a 22.5~23mm lens and I'm hoping the 24 is comparable on my film bodies. I don't know that I'd want to go that wide (A15/3.5) on film, especially with how soft that 15 seems to be across the frame.
I was talking more about how the DA15 is necessary for an APSC shooter since there aren't many other wide angle options. People can setup the rest of their kit to be FF compatible but they are probably going to have to pick a non FF lens for the wide angle.
I would probably pick a 20mm lens since it would create better spacing from the plentiful 28's, the magical 31 and the 35's. Of course I don't own a 20 because they are also more expensive (not ridiculously so) than the 24's. I'm also struggling to fit everything into the frame with the DA15 so being a little wider (20mm on FF) would be a benefit for me.
