Interesting read - yes Techno Geek here (I also used to sell them at a pro-shop before going freelance). Oddly, the first digital cameras used video CCDs which is why they have the same aspect ratio as a TV (1:1.33). Kinda funny to remember a 2MP DSLR that cost $12k! If you have a full-frame DSLR, your 35mm lenses will behave like always with the correct focal lengths - it's just the APS sized sensors that will change things for you. There's a good amount of wide-angle (though expensive) lenses for the APS sized DSLR sensors. I've been curious about this one - trying to use the lenses made for APS SRL cameras... Nikon and Canon kept their standard lens mounts - Minolta made a new one for the camera, and I can't remember what Pentax did - if they even HAD APS SLR cameras as well...? And yes, LostPatrol is right - making smaller sensor technology just mean they'll be able to fit more in the same amount of space, with hopefully less power needs. Hence, Nikon's new D2x 12.4MP camera - with an APS sized chip! Same space/higher res! And calling the x3 chip 10MP is a bit misleading. It's actually a 3MP sensor 3 layers deep (unless they actually MADE a 10MP sensor that I haven't read about yet). At best it competes with 6MP cameras for resolution and sharpness. If they actually made a 10MP sensor 3 layer deep that would blow the doors off of pretty much everything out there! Something to dream about... And save every penny for... Because it's gonna hurt in a 2nd mortgage or business loan kinda way! -Lew ;-)
