Back to more interesting stuff. Since I have been a slacker, I am going to borrow a little tid-bit from the Digital Photography School blog. If you haven’t been to this site or blog make a must see on your daily surf trip. I have picked up quite a few tips. I even find myself checking the site out and searcher out techniques and how to’s.
DX, full-frame, APS-C, FX, crop factor, 24×36, image circle. Confused yet? Good. With the new Nikon D700
hitting store shelves and the Canon 5D MkII imminent, now is a good time to clear the air on the whole sensor size thing.
Back in the film days, the rectangle that captured the image on a standard SLR (the film) was one size: 24mm x 36mm. That was all there was to it, and nobody really gave it a second thought.
Every camera manufacturer is slightly different; models from the same manufacturer are even different. People usually refer to a sensor’s size by its “crop factor.” That’s the number you use to find the 35mm equivalent of a given lens. It’s just like taking the middle of an image and throwing away the outside edges. If a sensor is 24mm x 36mm
, then there is no crop factor, since it covers the same area as 35mm film.
