Conclusion
The Pentax K-30 is basically a pared-down version of the K-5 SLR, with which it shares plenty of basic specs (except its shutter, which is much noisier). Picture quality and general handling are very good, and the K-30 offers plenty of exclusive extras for a camera at this price point. However, the body isn't as pleasant to handle as some competitor models and the video mode really needs updating.
The Sony Alpha 77 is a success on all fronts: its electronic viewfinder is good enough to silence critics (including us) as it avoids most of the usual pitfalls; the camera's performances are at least excellent and sometimes outstanding; and on top of that it has a high-quality build and finish. That said, the 24 Megapixels aren't really all that useful, there's been a slight drop in sensitivity, and some design and handling features could still be improved.

Cons

-

No rubber thumb-rest (comfort is debatable)

-

Live View is still slow

-

DA L 18-55 mm lens can vary in quality from one model to another

-

Shutter release is noisy

-

Limited video mode: no continuous autofocus, mono sound

-

AA battery adapter is an optional extra

-

No major progress in image quality, even a slight regression in sensitivity

-

Interface can sometimes be confusing

-

Buffer memory can be a bit tight (at full speed the bust mode is limited to under 2 seconds)

-

Battery life isn't as good as SLRs with optical viewfinders (approx. 400 photos)

-

Electronic viewfinder: still not quite as sharp as a 24 x 36 mm SLR viewfinder, slight display lag, dynamic range could be better
