Yesterday, Canon set the local forums alight with speculation when it was noticed that their EOS 5DMkII full-frame DSLR now goes for <S$3,200. This is a >$500 price drop.
Do note that the 5DMII is a full-frame camera.
Some may prefer the APS-C cameras as they offer a 1.6x magnification. (better than FF, IMO, for planetary/moon/DSO shots)
