Advice on what digital camera to buy
I do enough photography that people ask me for advice on cameras. Some time ago I wrote an article about what lenses should I buy for a Canon DSLR which has turned out to be fairly popular. The thrust of that article, by the way, is to convince you that there is only minimal point in buying a DSLR that can changes lenses and getting only one lens for it, even if you plan to get another lens later (after your camera has depreciated plenty without using its real abilities.)
However, many people come with the higher level question of which digital camera to get. There are many cameras, and lots of right answers, but hopefully I give a few in "What Digital Camera Should I Buy?."
Here, the advice has some specifics and some generalities. Both Canon and Nikon are good, but stick with the major brands so you get accessories and an aftermarket on eBay. And the answer, if you are serious about your pictures, may be to buy more than one. We've got three -- plus another 2 we don't use.
