More news continues to roll in regarding the Sony Alpha a7RII and its features and compatibility.
As a Sony shooter myself, I have truly experienced first hand the frustration of using adapters to migrate my Canon glass to the E-Mount. Specifically, autofocus always gave me trouble.
According to a hands on review of the a7RII done by the people at DPReview, the on sensor phase detection AF works, “very well”, and that’s big news!
This also has been tested on multiple different adapters, such as Metabones EF to E Mount Mk. IV and the Sony A-Mount to E-Mount adapter.
The problem in the past with using such adapters has been that the distance between the lens mount, sensor and phase detection sensor had to be identical. Since the phase detection was functioning without factoring the extra distance of the adapter, autofocus became a lengthy, difficult and sometimes impossible task.
All reports tend to point to an end to this frustration on the Sony Alpha a7RII.
“Focus appeared to be on par with OVF focus on a native Canon body, and the AF experience itself didn’t appear to be limited simply because you’re using a third party lens (full coverage and tracking are available).”
This means that shooters can take a more comfortable step away from the bodies that they’re more used to (Canon or Nikon specifically) and not have to abandon their high quality glass along the way. Sony is just making the path away from your old body easier and easier to navigate.
The list of reasons to not shoot Sony are becoming thinner and thinner.
Sony a7RII on-sensor PDAF Works “Very Well” with Canon Lenses via Metabones Adapter!
According to DPReview Administrators (who just wrote a hands-on Preview with Sony a7R II article), the new announced Sony Alpha a7R II (B&H Photo / Adorama)’s on-sensor phase-detection AF works “very well” with Canon EF lenses via Metabones Adapter.

“Agreed. PDAF works with Canon lenses via Metabones adapter, and A-mount lenses via the LA-E3. We’re checking to see if you actually get the full AF coverage with subject tracking, but for now, consider our minds blown. :)”
“It works, and it works very well. And yes, I just saw it demonstrated.”

Via Youtube Description:
Your shots of action can look clearer than ever, thanks to a new full-frame image sensor that assures wide-area coverage with 399 focal plane phase-detection AF points. With its accelerated readout and an advanced algorithm to anticipate subject movement, the sensor also makes it possible for the Fast Hybrid AF system to raise speed, accuracy, and tracking performance to incredible heights. These smart capabilities outperform those of conventional AF systems to deliver crisper images that make the most of the camera's unprecedented 42.4-megapixel potential

With the world's highest* magnification at 0.78x (full-display diagonal field of view: approx. 38.5 degrees; live-view-display diagonal field of view: approx. 37.2 degrees) among digital still camera viewfinders and a new four-lens optical system with double-sided aspherical elements, the XGA OLED Tru-Finder provides views of cutting-edge clarity and contrast throughout the entire width and length of the display. Better yet, ZEISS T* Coating ensures absolutely minimal surface reflection.

α7R II – Product Design | α | Sony
Via Youtube Description:
See reality as your mind's eye envisions it with the incredible new Sony α7R II. The world's first*1 back-illuminated 35mm full-frame CMOS image sensor gives this camera capability to deliver 42.4-megapixel*2 resolution, high sensitivity and fast response that are apparent in every amazing picture. The Fast Hybrid AF system's extra-wide dense focal plane phase-detection AF coverage keeps subjects in sharp focus, while 5-axis image stabilization reduces blur which otherwise tends to affect handheld shots. High-resolution imaging is further enhanced by 4K movie recording now featuring full pixel readout without pixel binning. With so much innovation packed into such a compact form, it's clear that there is more to life than meets the naked eye.
