Sony A7 with Pentax Full-frame Glass - Performance / Handling of Pentax K-mount Lenses - PentaxForums.com
"While the image quality is not the issue, manual focusing on the A7 is the Achilles heel of using this camera in connection with Pentax lenses.
- Even with focus peaking, depending on the brightness of the scene, it can be difficult to impossible to achieve spot-on focus
- Focus peaking is overly optimistic as to what is in focus
- It is not possible to focus manually with any accuracy if focus peaking is deactivated"
the magnify function is more accurate than focus peaking, but as you can see, adam never even tried it.
don't quote a bogus review as if it was fact.
fyi, that magnify functionality will give you better focus accuracy than anything that pentax has ever put on the market.

Don't understand how shooting video came into the discussion either.
i suspect that multiple people in this thread are comparing different technologies?
Originally posted by cali92rs Sony could've had 14-bit lossless RAW which wouldve resulted in higher IQ files, but they didn't, why not?
pentax could have given us a full-frame sensor years ago, but they didn't, why not?
"The Sony A7R is in a totally different league in regards to dynamic range at base ISO 100. This image reveals the exceptional signal to noise ratio and high IQ RAW performance.
It's no secret that the Canon 5D Mark III does not have the cleanest shadows at base ISO. Canon shooters have adapted to its shortcomings by bracketing and exposing images to the right (ETTR). It's usually unnoticeable in good light if you don't start playing with the shadows too much in post. But, even perfectly exposed shots in high contrast lighting will have color and luma noise in the shadows when pushed one or two stops. To make matters worse, you might even find some banding or visible horizontal and vertical line patterns."
