The concept camera, one of which is pictured here with a large lens, features a larger image sensor than is found in most compact cameras. Some are calling this category of cameras "EVIL," short for Electronic Viewfinder Interchangeable Lens compact cameras. Sony hasn't announced a timeline for manufacturing the concept camera yet.
Speculation is that Sony is trying to compete with the Micro Four Thirds format for advanced cameras. Olympus has released three PEN model cameras in this category, and I really enjoyed trying the compact Lumix DMC-GF1 DSLR camera from Panasonic recently. The idea of smaller interchangeable lens cameras is certainly becoming more popular, and Sony's concept camera looks a lot like those Olympus and Panasonic models.
Samsung's NX10 model is another smaller-than-normal advanced camera, and it recently won a DIMA 2010 Innovative Digital Product Award. It's worth keeping a close eye on the development of all of these compact interchangeable lens cameras.
