    What is the effect of megapixel count on the maximum size print one can make from a picture?

    I'm trying to decide between a used EOS-1D and a new 20d, and I'm concerned with the small pixel count on the 1D. I have a rebel now which of course is 6.3 Thanks

    It depends on the sensor. I've heard that you can get just as good of pix from the 1D as from the 20D, but I'm not convinced. If it were me, I'd either get the 1D MK II or the 20D. Not the 1D itself. :)

    Megapixels directly affect print size. If you want a high res 16x20 print, it's 4800 x 6000 pixels at 300dpi. An 8 mp camera won't have to stretch as far to get those dimensions.

    However, if a 6.3mp jpg has less noise and is sharper than an 8mp one, it will look better at a bigger size.

    A lot of it will be specific to what you are shooting, but in general, more megapixels make larger prints easier.

    Matt,

    That was my understanding as well. I wish I could afford an mkII but alas even on an IT salary that is out of reach :( Looks like the 20d is my best bet. I have read it's pretty good for sports, but not what most of the pros use. One step at a time I guess, thanks

    Ryan,

    I suspect that pros do use a 20D, and the only reason that they wouldn't is because they already have a 1D, or 1D MKII. I'd still be willing to be that a lot of them bought one as backup.

    How big are you gonna print?

    I've done 13*19 prints from the rebel.

    I've printed 20x30s that look amazing.

    That's only true if the sensor sizes are the same dimensions but different pixel counts. If the actual sensor of the 8mp is larger, than it can be just as clear and noise free as the 6.3mp one.

    You can look up actual sensor sizes for your camera at dpreview.com. The bigger the pixel the better.

    My boyfriend printed a 20x30 from his rebel that looked awesome too. It's of Chicago from the Sears Tower...really awesome stuff.

    The only real avenge of the 1D MKII 8mp or 1D 4mp (old model) is speed, they both shot at 8fps, on the 1D MKII the bursts is 40 frames, good for sports or models on the runway. D20 is basically just slower and about 2000 dollars less. The older 1D is still a good option for sport reporting, because the 4mp is fine for newspapers

    Now 1Ds MKII is hold differ story 16.7mp, 4fps, burst 36 frames

    Personally I would like a 1D MKII for shooting baseball.

    I'm talking on a picture to picture basis. An 8mp shot at ISO 800 and 4 seconds will not look as good at 20x30 as a 6mp shot at 1/200 and ISO 100. Or if the the 6.3mp is just a sharper image. 90% of getting good large prints is having a tack sharp (tripod sharp) image that is very clean.
