Digital crop factor, what's up? OK, so a digital SLR that has a CCD (or CMOS) smaller than film will give a cropped image when shot through a lens designed for film. A 28mm wide becomes about a 45mm (1.6x factor), meaning that the angle of coverage more resembles that of a 45 than a 28. If a I try to take a portrait with a 28 (I know better than to do this), the nose becomes rather disproportional. When I use this 28 for a portrait on a digital, do I still end up with the same schnozzola effect in my portrait, only cropped so it looks like a 45? I'm told to use a 50mm on a digital SLR to get the portrait effect of an 85-100 short tele. When I do this, am I getting merely a cropped image through a 50 or am I getting the flattering perspective one usually associates with short teles? OK, here's what I'm getting at. It seems to me that if I shoot digital, then I should be using lenses designed for the small collection device of digital. OTOH, pros shooting weddings are coping quite well with the crop factor, without dropping 8 grand for aa 35-frame-sized sensor. Where's the disconnect between their apparent success and my thinking?
