first, its really lame. I've found an XT with Lense for $639 before shipping, but its silver, and I also noticed the black, for $769 . Why such a large price difference? regardless of place, its usually 50-100 difference for the color. Myself, I am partial to black, but I'm not sure if I should justify spending the extra cash just for a color... and the second question... after looking at a few sigma lenses, there are two kits I noticed, at first glance, I thought they were the same, but the #'s are different. Amazon lists the kit for $229, another place i looked was $199. Amazon ~ Sigma 28-80 F 3.5-5.6 Autofocus Zoom, and 70-300 F 4-5.6 Autofocus Zoom Other Place ~ Sigma 18-50 F 3.5-5.6 DC, and 55-200 F 4-5.6 DC now I am just assuming that the DC = Digital Camera, since there is somewhat of a rant of what the circle is made to match smaller dimensions, etc. but the main question is, whats different between the lenses? is one right and one wrong? or are they two completely different pairs of lenses?
