Comparisons
Nikon D50 - The low end of the Nikon line is the D50. Like the GX-1S, this is a 6-megapixel DSLR sold with an 18-55mm zoom. The Nikon goes for about $650 online with that lens. For another $150, the D50 comes in a kit with a 55-200mm zoom. Though the Nikon's autofocus looks less sophisticated, with 5 focus points instead of 11, the autofocus on the D50 performed much better for us. The Nikon lacks an ISO 3200 setting, but the GX-1S's performance at 3200 is incredibly noisy. So, for the same $800, with an extra lens, the Nikon looks like a better deal.
Canon EOS Rebel XT - The Canon Rebel XT is an entry-level DSLR with 8-megapixel resolution and image quality that takes advantage of the extra 2 million pixels. For the same $800, it offers better image quality than the GX-1S and somewhat better autofocus, though a less sturdy chassis. The Rebel XT also comes with a lithium-ion battery, which should last longer between recharges than the non-included NiMH AA's in the GX-1S
Pentax *ist DS - As far as we can tell, with the logos covered, the GX-1S and the Pentax *ist DS are virtually the same camera. Spokespeople for Samsung at the Photo Marketing Association convention this February, in fact, said that the GX 1L is a Pentax with their logo on it; Pentax had no comment. We haven't examined an *ist DS, but as far as specifications are concerned, the 2 cameras are a lot alike.
