Hi Vinny,

Thanks for the tips. I do have a portable Epson storage drive. I was reading an on-line review of the new 5D and found this interesting (in light of your saying how much memory those 21mp shots eat up. See his comments below on resolution. I suppose one would have to know how much cropping would be done. I don't crop that much with landscape shooting so lower res. might be an option. Evelynn : )

Resolution
No one needs 21MP. All it does is slow everything and clog your hard drive.
Try shooting your 5D Mark II at it's M (11MP) or S (5MP) settings. If you look at your images at 100%, you'll see that the lower resolution shots are sharper!
Why? Because they use less, or no, Bayer interpolation. No digital camera really resolves its rated resolution; they cheat and interpolate up, so at 100% at its rated resolution, no digital camera image is as sharp as a true scan from film.
At the 5MP setting, you have 100% R, G and B pixels, exactly as if you were using a Sigma Foveon sensor. If Sigma was selling this, they'd sell the 5MP (S) setting as if it were 15MP (also a lie).
What this means is that the lower resolution settings actually pack away lot more detail than you think. The S (5MP) setting of the 5D Mark II is a lot sharper than any 5MP camera.
When I'm photographing family and friends, I shot at S!
Likewise, there may be very little extra real definition gains by shooting at L, as opposed to M. M many be all anyone needs for any size enlargement.
If you're testing lenses, sure, shoot at L, but for everything else, try the settings for yourself, You'll probably get what you need at the smaller settings. For instance, the 11MP setting of the 5D Mark II has way more detail than any of the 12MP (native) Nikon cameras.
The resolution advantage of the 5D Mark II is obvious, even at lower settings. Try them.
JPG Compression
Canon defaults to the FINE (quarter circle icon) setting.
I prefer the NORMAL (stair-step icon) setting. It gives me files which look the sam as at FINE, but take up half the file space.
Canon cameras are extremely smart; much smarter than Nikons. The file sizes are all automatically optimizes for each shot, using more or less bits as needed to retain quality based on the detail content of the image.
