I have a question about different digital camera models?

I am looking to buy a Canon digital camera. I realize that there are many different models. I was wondering if the later models, or the ones with higher numbers (ex. SD1000 & SD850) are better than the others. Also, I am looking for very good image quality, reletivley small sized,at least 7 mega
pixels, and the option to enlarge pictures without them losing their quality. Which Canon model do you think I would be best off buying?

There is no definite rule for determining quality or features, especially from a company that makes so many models. The best thing to do is compare reviews of the models that have a feature set you are interested in. To see a fairly objective review of different camera models try some of the on line web sites.

I like Steve's Digicams because there are reviews of many cameras, it is pretty open minded (fair) and has a very consistent testing method. Each review is divided into sections and has one called Steve's Conclusion that summarizes the good & bad features of the camera.

The site is also very well organized so you can find cameras by mfg., no of MP or when it was reviewed and there are many links to additional information.

Hope this helps. Good luck!

sd850 is your best choice
if you wait about a month
the sd870 is coming out

You might want to check the Sept. 2007 issue of Shutterbug magazine for their review of five 10 mega pixel digicams..From my reading, the Canon G7 was the better of the group. You can also go to shutterbug.com and read it.

My absolute favorite Canon is the G7. Superior photo quality, small and easy to use while still offering full control. The price is a bit high now, but in October the G9 will be released so the G7 price will drop quite a bit. I am a pro photographer and this is THE camera I take with me almost everywhere when I can't take my huge dSLR. Check out some of the photos taken with the G7 on Flickr and if you can, click on the "see all sizes" button on top of the photos to see larger sizes.
