I am looking at purchasing the Canon EOS-300D Rebel w/lens kit. I would like to hear from the owners what they think of this particular SLR and what problems and frustrates them the most about this camera. Do the the majority of the lenses cannon makes fit this model?

Thanks
Mark

I have the 10d but he 300d can handle any of these lenses :)

Read THIS, and then check out the other three reviews listed at the bottom of the page. That should be more than you ever wanted to know about the Rebel.

how do you measure zoom on a certain lens...i know the digicams just say 3x optical, but is there a way to know with the slr interchangable lenses

I think 35mm is considered 1X. On a DSLR, you have to multiply the focal length of the lens (100mm or whatever) by the crop factor for that camera (1.6 on the Rebel, 1.5 on the D70) to get the effective focal length. Example: 100mm lens x 1.6 on a Rebel = 160mm = 4.5x zoom (160mm/35mm).

Check out //www.dpreview.com - they have a huge forum on the 300d which is very helpful.

Good luck

PS - I love my 300D.

there are two ways to consider the zoom factor using the nX standard. The first and most common with digicams is simply to compare the smallest focal distance to the longest focal length.
Examples:
Canon G5 (7.2mm-28.8): 4x
Canon slr 70-300mm lens on a 300d or 10d: 4.29x
[where both are derived from dividing the larger focal length by the smaller]

The second way is to compare the "normal" focal length with the largest zoom focal length. (giving you an overall idea of magnification potential)
Examples:
Canon G5: 2.8x
Canon slr 70-300mm lens on a 300d or 10d: 9.6x

(Explanation: normal focal length for the G5 is considered 10mm therefore 28.8/10= 2.8; whereas normal for canon 300d/10d with 1.6 cropping factor is 31.25mm therefore 300/31.25=9.6)

What is interesting to note is that digicams are always touting their focal length comparison stats...i.e. the 4x for the G5 but never the normal/magnification stats. The 70-300 seems almost the same in the first comparison but is seen to be vastly different in the normal versus comparison. It's a little confusing at first, but then again, it's really like trying to compare vests to bicycles :)
