You could use more zoom to get the same picture, and you would have more information from which to work. You also would have more issues with DOF compression and other issues you use with any other zoom lens. With the zoom what you see in the view finder would look the same though How ever if you used an 80mm lens on an APS sized sensor, and an 80mm lens on a full frame, though it would look different in the view finder after cropping it should be the same. Now you bring up other things with pixels. You are exactly right not all pixels are the same. These 5 and 6 mp cameras with a sensor the size of a pin head simply isn't that effective. Lots of issues come into play. Noise is one, just like you mentioned but its a total package. Everything has to work together. Technology is still improving. Stuffing the same number of pixels into an APS size sensor is more ofa challenge than putting them in a full frame one and still keeping other things equal. Trouble is that if you can put X pixels in an APS size sensor, you can put Y in a full frame with the same technology. The more information available the more youhave to deal with which means different software in the camera. The 5D isn't as fast as many and lots of sports work needs speed and quality. That's why those guys typically go top of the line. An $8000 body isn't so bad if it keeps youfrom spending $40,000 in processing. The 5D is popular with those that don't need as much speed and is a fine camera. So are lot of APS sensor cameras. It just a matter of what you need. --- On Sat, 4/19/08, PhotoRoy6@xxxxxxx <PhotoRoy6@xxxxxxx> wrote: > From: PhotoRoy6@xxxxxxx <PhotoRoy6@xxxxxxx> > Subject: Re: APS vs Full Frame?
