Anybody have good resources to read up on how all these affect digital SLRs?
I thought I got it already. But the more articles I read around. The more confused I am.
First I thought the 1.5x crop factor in DLSR on your yesteryear lenses gives you a 1.5x magnification as well. E.g. 100mm becomes a 150mm lens. But after reading an article by Thom Hogan (could be somebody else out there.) I was told there is no magnification at all. You just get the Field of View of 150mm from a 100mm lens. E.g. If you shoot a pic in Film scanned it at 6mp. Then shoot another pic in digital 6 mp. Your digital is bascially a crop of the film version.
Then again today. I was reading Focus mazagine while attending to some business. The article regarding the AF-S 300mm VR lens states clearly on a digital body, the focal length will be increased to 1.5x and the Field of View is reduced (not in the exact same words.)
Am I missing a dimension here?
