Eos 10D Cropping Can anyone please explain the cropping on this camera. Also, when the camera crops the photo does it decrease the megapixels down to 3 megapixels? 7/30/2003 2:13:53 PM |

The 10D uses lenses designed for 35mm film. These lenses are designed to fill the 24mm x 36mm frame of film. On the 10D, however, the digital image sensor is smaller than 24mm x 36mm. Hence the image provided is cropped in comparison to 35mm film. It does not affect the megapixel count.

The actual term is not crop which may be why there is a bit of confusion. It is actually a Focal Length Multiplier. It is similar to cropping a picture (thus the term crop factor' but it is actually because the sensor is smaller than a 35mm frame, it just sees a smaller angle when shooting thru the same lens as a 35mm. Different cameras have different amounts of compensation to figure out the equivalent coverage of a 35mm lens. The Canon EOS-10D for example is 1.6x the focal length of a 35mm lens so that 50mm lens that so many people have would be 80mm on the Canon. If the sensor is 6MP like on the Canon then you get a 6 MP image. It is just not using the complete lens surface available. This is good for most things but bad in another way. The Good is your telephoto/zoom lenses now have a greater reach. Your 200mm lens is now the equivalent of a 320mm. Also the weakest quality of a lens is the corners and because of the smaller CMOS/CCD imager you do not use as much of the corner so you would find sharper corners on a picture taken with the 10D than if that same lens was on a 35mm film or full frame camera (like the 1Ds). The Negative is your wide angle lenses are now not as wide. Your (or my) 15-30mm wide zoom becomes a 24-48mm equivalent lens. Hope this helps you understand the "crop" factor of the new imagers. There is a wonderful article with examples if you care to read more at the Luminous Landscape site: http://www.luminous-landscape.com/tutorials/understanding-series/dslr-mag.shtml 8/13/2003 5:30:43 PM |

I have Canon lenses for my Canon A2 camera. Will they work on the Canon 10D as well?

The 10D is a 6.3MP camera. The pics are 3076x2052. Truly an amazing camera for the price. There is also the new model available which is like $400 less called the 300D or Digital Rebel but is lacking some features. The 10D can use any Canon EOS lens. 8/26/2003 3:18:51 PM |
