Hi, A 50 mm. lens, either a macro or plain version, will 'make the effect' of a 75 to 80 mm. lens with a DX format. Does that mean that I'll also get noses a bit wide when doing prtraiture with a 50 mm. lens?? Has your experience being positive with this focal lens on a DX body? Thank you, kind regards, igmolinav : ) !!
