5 out of 5 eggsLOVE IT

This review is from: Sony Alpha NEX-7K/B Black 24.3MP DSLR Camera With SEL1855 Lens

Pros: I love you SONY.

Cons: Don't think if you want one.

5 out of 5 eggsBest ILC on the Market!

This review is from: Sony Alpha NEX-7K/B Black 24.3MP DSLR Camera With SEL1855 Lens

Pros: 24.3 MP
ILC - interchangeable lens camera
APS-C sensor
Compact form factor
Decent battery life

Cons: There's some loss of image clarity in very low light situations that I've noticed does not occur with my friend's D7000, but other than that I've found no real cons.

Other Thoughts: This camera is listed as a DSLR in the product title - this is false. This is not a single lens reflex camera; the camera is an ILC (see pros), with an APS-C sensor (same sensor found on mid-range DSLRs). The viewfinder is electronic.
