I had some inquiries at my recent workshop about the kind of digital camera I use, so I thought I would post that information here:
What I use is a Canon G5 Digital Camera . I am no expert on these kinds of things, but I did a lot of research before purchasing, and this is a good 5 mega-pixel camera. At the time of purchase it was NOT cheap, but it had the highest number of mega-pixels on the market in an attainable price range. This is no longer so. There are many other very good cameras on the market, but the G-5 is still very good, so I will have to stick with this one for a while longer.
It is not compact, but more like a traditional body single lens reflex camera. This is something I will need to reconsider in the future because I travel so much and now long for something more compact. It does have a good zoom and can shoot macros (for close up shots) which were the two criteria that were high on my list of priorities. But it is not good at all for action shots (something I don't really need for landscapes and city shots).
The only thing I really don't like about my camera is the lens cap. It would be much better if it had an automatic retractable lens, as the cap can sometimes fall off and you end up needing to clean the lens a lot. (I had a time when I was in Italy trying to figure out how to say, "do you have any lens paper?" in Italian. I think I ended up saying like "Do you have anything for to clean this?" pointing at my lens.) This problem may have been remedied in the next generation of this camera though. There is a newer version out now (the Canon G6Â ) that has 7 megapixels. There are also other cameras that have 8 MP and more, so one has a lot of choices, depending on the budget of course. Basically the more MP's you have the higher resolution images you can shoot. The G5 has been discontinued, but is still sold through various outlets. Here is a VERY detailed review of the G5.
You can read more about newer Canon cameras, including the next release of my model (the G6) here.
If you have an opinion about a good digital camera with good zoom and macros, feel free to post a comment about it!
