Currently Steve is using a Canon EOS 5D digital SLR, pictured above. This camera is one of the first reasonably priced digital SLRs with a full size sensor equivalent in size to a 35mm film frame. At 12.8 megapixels it takes very satisfactory photos.
If you are considering buying a digital SLR camera, Steve certainly recommends the Canon line. Of course if you already have a collection of lenses for another brand of camera, perhaps from an older 35mm SLR, you might want to go with that brand in order to continue using your lenses.
Many people report complete satisfaction with Nikon cameras. There are other well respected brands too.
It is extremely easy to use a digital camera. And it's easy to muck about with the images later on your computer too. Most digital cameras include photo editing software on a CD.
