I was just checking out the new Canon SD 1100's specs and they seem pretty good. Actually they seem better than the SD850is, SD870is, and SD900s in terms of specs. How come it's cheaper though? Aren't usually models in succession (like the higher the number, the more advanced), better they are and more expensive? The Canon SD1100's are available for about $245, while the SD870is's are about $275. They are both pretty comparable in specs: - Both are 8.3 Megapixels - Both have same ISO settings (80 through 1600) - Both have same Still Image Recording specs - Slightly different focal lengths - 1100's 6.2-18.6mm to 870's 4.6-17.3mm - Same Digital Zoom - Same card types - 1100 has a couple more shooting modes - Almost same shutter speeds - 1100 at 15-1/1500s and 870 at 15-1/1600sec The biggest difference is the screen size - which the 1100 has a 2.5in compared to 3in for the 870. So what's up with the price differences really? Are they the same camera basically except for the screen?
