Luminous Landscape (Click here) posted their full A7rII review. They conclude:

With so many cameras crossing my desk each year it’s hard not to cozy up with the prettiest new face on the street. But the A7RII is more than just a pretty face. It’s a highly competent tool for creating images that gives up almost nothing to any competitor, and while it doesn’t win every race, it places in the top three if not the very top in every category.
It’s now only August, and there’s a long way to go until December 31st. But, unless another company pulls the proverbial rabbit out of a hat I wouldn’t be at all surprised if when year-end comes that the Sony A7RII doesn’t become most reviewer’s “2015 Camera of The Year“.

They also shared some “impression” about the A-mount future:

I can’t give a definitive answer, but when I met with the senior Sony executives in Portland, and asked this question, I found their responses evasive and vague. In my experience this usually means “No“, but with no one really wanting to actually say so. It may well be that the answer is yes. I just can’t be sure.
More informative was the unsolicited comment from one of the people at the table. The gentleman said…”The A7RMII would make an excellent camera for anyone invested in A mount lenses. Just add one of the inexpensive mount adapters, such as the LEA-3 and all A series lenses will work perfectly”. This adapter sells for about $199. The more expensive LEA-4 isn’t needed because the A7RII has Phase Detection AF built into the sensor itself and doesn’t need the Translucent Mirror Technology of the LE-A4.

An interesting comparison has been made with the Pentax 645Z medium format camera using the large 50MP Sony MF sensor:

Colour rendition differs (both were set to Daylight WB) but most obvious is that the Sony with its 90mm Macro has higher internal contrast. When subjected to ultimate pixel peeping (200X and 300X) it is extremely hard to see any difference in resolution, which really is a testament to the Pentax 120mm Macro. Subjectively, overall, I give the win to the Sony, but only slightly, showing that the 50MP over 43Mp sensor size is a quibble.

Yannick Ciancanelli (Click here) posted a long Canon EF lens with A7rII autofocus performance test. Along all “normal” Canon lenses tested by Yannick he also had the chance to play with the massive [shoplink 39571 ebay]Canon 600mm EF lens (over $10,000 price here on eBay)[/shoplink]. Yannick writes:

“This stunning lens’ AF, sadly, does not work that well. Focus picks up sometimes. It depends on contrast and subject. Face detection helps a lot. Without it the lens would be lost, but when faces show up then boom it’s nailed. Does not focus in-between shots (High Burst rate of 5fps).”

And here is the video showing the A7rII with the lens:

Kai from Digitalrev tested the new Sony A7rII. And he surprisingly has really nothing negative to say about the A7rII. For him the camera it’s just ” bloody awesome!”.

Dpreview posted their big autofocus Sony A7rII test and their conclusion is absolutely sensational:

The a7R II, when paired with a bright lens, can match or exceed the performance of the best DSLRs with respect to low-light AF ability. And we haven’t even shared the most exciting thing with you yet: although in this video we show you results at -2EV, our ‘extinction’ tests measured -3EV as the failing point of phase-detection with the a7R II + 35mm F1.4 combo. That’s very dark, and represents potentially game-changing performance, in our opinion.4

Sounds like for the very first time Canon and Nikon managers will REALLY have to worry about Sony taking away the spotlight from their Full Frame Pro market!
