it depend from use...

Some bad mistakes on this review.

Pentax K-5 it's not limited at ISO 12K but it's 51K, and have 1080p@25fps, pretty same of 24p.

Nex-7 can shot in 0,0002 seconds, you should check it better, it's a real fast camera, I think a faster one on the market. 

I think I'll get a k-5, but my doubts are abut videos, Nex it's really better (continuous focus, exposure, etc.), with good lens, but at hi-ISO? Which one it's better?

Do some one compared next-7 to K-5 about video performances? I hope K-5 it's not so bad for that.

About Photos, K-5 it's simply one of the best cameras of the world, and Nex-7 may be, it's on the second place.
