In particular, informal head and shoulders shots look a bit odd if I'm close to the subject. The shoulder may seem enlarged if I'm taking a profile, for example. Whereas a 50mm would compress this distance more. I thought I would be at home with the 31mm limited on the D, but using a wide angle lens to achieve a normal-length crop is a bit wonky to me. I still like it, I wish I was using a 50mm focal length instead of a 31mm lens cropped. -R -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
