Although some cameras are better for some people than others (I personally could not shoot with a camera that doesn't have an eye level viewfinder) and some camera systems are a bit better in certain areas than others; I really don't think that a person (especially a new shooter) can go wrong with purchasing virtually any DSLR on the market today. Or even a fairly recent model used DSLR camera in decent condition. I shoot infra red with an "old" Canon D60 (not the 60D) modified for full-time IR which still takes very decent pictures.
We are fortunate in having a plethora of great cameras and lenses available both new and on the used market. We are fortunate in having the Internet (caveat: beware of scams) on which to select our gear and forums such as this to answer our queries and to post our images. We are fortunate in having an imense selection of lenses that allows the photographer to shoot in virtually any venue.
However, most of all, I consider myself fortunate that I don't hear the jingle of a cash register (remember those things?) every time I press the shutter button. I can also save my images to a computer and not have to keep them in a shoebox.
I wish I had been fortunate enough to have done all of my photography digitally. I can just imagine what a wonderful collection of images (most of which have been lost to time and several moves to different homes) I would have now. If I had owned a digital P&S camera, and kept it in my shirt pocket, during my years as a Navy motion picture photographer, I could have documented events which are only retained in my memory now.
These thoughts have been stirred up because I just bought a thirty-year old Kodak book on close-up photography which brought me on a trip down "memory lane". It was only twenty-five cents from my local public library's book shop. Taking a trip back in time while reading this book started me thinking about how much easier we have it now than photographers of not that long ago had it.
The Full-frame vs. Crop arguments or the Prime vs. zoom cat fights are really nothing in comparison to the trials and tribulations (as well as the expense) of the earlier film photographers.
