<p>Sujan, I have been using a 450D (XSi) since about three years now, with the 18-55 kit lens. Unless you are limited by need for fast auto focus, faster raw buffer frame rate, or higher resolution (pixel counts) I see little need to upgrade to a 7D or 5DMKII. If you find the 450D's body to be a bit too small for your hands, consider purchasing a used extra battery pack- that makes the camera much more comfortable to hold (at the cost of weight). Actually the 450D body is quite light weight (I do not have either 7D or 5D but I have tried each of these cameras from friends and they are both quite a bit heavier). My suggestion is to consider upgrading to better lenses rather than body. For the cost of either of these bodies you are considering, you can purchase a 70-200 f4 L _and_ a 17-40mm f4L (both non-IS) lenses. Since you already have a 50mm prime, you will be all set with the focal length coverage, and with excellent optics. In future if you upgrade to a full-frame body, both these lenses will carry over nicely. I am sort of half-way through the upgrade I am suggesting: I got a 70-200 f4L lens six months ago- am really happy with it- great performance and not too heavy. I will get a wider L lens 17-40 or 24-70 sometime next year as budget permits- presently still using the kit lens and 50mm f1.8 which is great for portraits. Hope this helps. Good luck!</p>

<p>Hope I am not too late. <br>

<p>Graham, where do you get your roll developed and scanned, and what is the scanning resolution (dpi)? I have been using a canoscan flatbed scanner ewith MF negative adapter but the results are not that great; and I spend too much time with dust-removal etc. Thanks. </p>

<p>Thank you all very much for your replies. I admit not reading the user manuals for either of the lenses. </p>

<p>I have just recently moved over to Canon (XSi) from Nikon (D70S) and I have the 18-55 and 55-250 IS lenses.<br>

I noticed that with image stabilizer turned ON, while the camera is mounted on a tripod, there is a slight image-shift (mostly appears to be an upward shift) on pressing the shutter-release half-way. The shift is absent with IS turned OFF. There is no need for IS to be on of course, while on tripod, but I am just curious why the IS behaves this way. Should the IS necessarily be turned OFF while on tripod? Thanks.</p>
