I mostly lurk here, however I do have a question that I have had answered is two different ways, and always by someone who knows more than me.
The Pentax dslr's have a 1.5 crop factor, so this means either: 1) A 50mm focal length is still a normal perspective only with the sides cut off, because the sensor is smaller than a 35mm negative, and so the recorded image is simply smaller because of that. ....or.... 2) A 50mm focal length is now a medium telephoto perspective, with the same effects, with regard to image compression (from front to back) and depth of field, in the same way that on a large format camera a 50mm focal length is a wide perspective. So.... I feel like there is some concept about the mechanics of a lens that I do not understand, but both explanations make sense to me, so I don't know. Russell
