Crop Factor Confusion Help! When I look through My Nikon D50 viewfinder, will I see the exact image my sensor will capture or the non-cropped version? Yes, I know I can just take a photo and find this out, but I need someone to tell me. Are there any rules of thumb to account for crop factor other than just remembering it?

When you look through the viewfinder on your D50, you see the same image(*) that your sensor will see. If you put the same lens on a Nikon 35mm film body or full-frame digital body, you will see the non-cropped view of the lens, and it will be the same image that will be recorded by that camera. If the D50 is the only camera that you use, then you really don't need to remember anything about the 1.5x crop factor, or field-of-view factor as it is also called. The crop factor is only meaningful to describe the view through a certain focal-length lens on a reduced-sensor digital camera as compared to the view through the same lens on a 35mm camera. So, unless you have a "preconceived notion" of what the view through a certain focal length lens would be on a 35mm camera, you don't really need to worry about the crop factor at all. You should remember though, that lens descriptions like wide-angle, normal, and telephoto as they have been applied to 35mm cameras for many years, are a bit different for a reduced-sensor digital SLR. Instead of 28mm being a standard wide-angle lens, you should use about 18mm. Instead of 50mm being a normal lens, you should use about 30-35mm. Hope this helps, Chris A.

Thanks chris it is becoming clearer. I am basically learning that I can trust that what I see through the lense will be my shot.

Correct, Michael: "WYSIWYG". I.o.w. What You See Is What You Get. IF you look through a lens, though. Without an "e" at the end....

Michael, although not an issue about crop factor your view finder may not totally represent exactly what the picture will look like. Even in the D2x, the viewfinder is only about 98% of what the sensor actually captures. I know the D70 was less than that. I am not sure what % the viewfinder on your camera shows. You might want to play around by taking pictures of something that you are very familiar with and immediately what you saw in the viewfinder with what shows up on the LCD. This will give you a feel for how much extra space you will have at the edges of your composition. Bill
