The new full-frame Sony alpha DSLR-A900 is a great, albeit relatively expensive example when compared to the typical D-SLR with smaller APS-C sized sensors. This beefy camera has a 24.6-megapixel full-frame imaging device, and sells for “only” $2,999. The new Nikon D3X also has a similarly-sized sensor (made by Sony) and it costs a cool $7,999! Yeow! The D3X is an incredibly featured camera, obviously designed for pros whereas the A900 is for well-heeled enthusiasts—but not investors in Bernie Madoff’s funds.
