Sony alpha 900
The Alpha 900 represents in a nutshell the almost schizophrenic nature of Sony's digital camera division, which can market compact cameras with smile detection and a Playstation style user interface at the same time as this, perhaps the most pared-down, frill-free and unashamedly 'serious' DSLR we've seen in a long time. You can't help feel that Sony's long-held worry that as a consumer electronics giant it will never be totally accepted as a serious camera manufacturer has been instrumental in shaping a flagship camera that studiously avoids the creeping 'gadgetization' of DLSRs and concentrates on old fashioned stuff like picture taking.
