I've got an SX10 (as well as an A630) and I rate its macro capabilities well above my photographic skills to utilize them.
In addition to the normal macro mode, the SX10 has a super macro mode which will focus on objects *touching* the lens.
This picture...
was taken with the cube touching the UV filter I use to protect the main lens. The filter is perhaps 5 mm from the main lens.
The real advantage of the SX10 is its 20X optical zoom (28-500 mm equivalent) in a compact package. It's smaller and, naturally, lighter than an SLR so much less onerous to carry about. Here's an example...
of its telephoto capability. The cranes were about 40 yards from me when I took this shot at near maximum lens extension.
I'm of the opinion that, like lathes, no one camera will satisfy all my needs. The A630 is a great camera, perfect when even the SX10 is too much to lug and I want better performance than I can get with the new SD780.
I just wish I were a better photographer. While I understand the physics and mechanization, I lack the artist's eye needed to do really good work. I keep promising myself to take some classes but I never get around to it.
