Philip Reeve posted all the test samples and final conclusion at SystemKameraForum.de. I kindly invite you kindly to visit the site. If you don’t speak German I got his permission to repost the results on SAR (translated by me):

Philip is extremely pleased by the lens performance on the A7r. Most lenses work extremely well on the Sony and here is the single evaluation of them:

Sigma 24/2.8: From f/11 you have very sharp corners..

Carl Zeiss Biogon 2.8/28: A real disappointment. Massive Vignetting, Color Shift and Smearing on corners.

Canon FD 35/2: The center is sharp wide open. At medium aperture corner sharpness is increases and shows decent results.

Minolta MD 35/2.8: A real surprise! The Full Frame is sharp at f/2.8. Sharpness increases at f/8.0. Impressive for a lens that costs 15 Euro.

Carl Zeiss Planar 2/45: At f/5.6 the image is perfect.

Carl Zeiss FE 55/1.8: One word: Wow! At f/1.8 very sharp in the center and in corners. At f/5.6 an astonishing performance.

Minolta MC 58/1.2: Wide open it shows a certain” character” (not sharp but has a certain flair). Center sharpness is ok from f/2.0. At f/8.0 also corners are sharp.

Samyang 85/1.4: Already good at f/1.4. But corners never are truly impressive even at medium apertures.

Minolta MC 100/2.5: The lens is 45 years old but shows a very decent result at f/2.5 aperture (even corners are ok!). You will get the best results at f/5.6 aperture.

Minolta MD 100/4: Very good results at f/4.0. Improves a tiny little bit at f/5.6. A very solid performance for a 80 Euro lens.

Minolta MD 135/2.8: A disappointment. Corners are never sharp at any aperture.

Again Thanks Philip and SystemKameraForum.de for posting such an interesting test!

DxOmark (Click here) just published the full Sony A7r sensor test. And according to their measuresand ranking system the camera scores the same points as the Nikon D800-D800E (and that for $500 less). And it literally kicks the Canon5DIII in the butt (DxO comparison here). This is what DxO writes about the A7r:

“Although we can’t provide any commentary on image sharpness at this stage in our tests, the sensor in the Sony Alpha 7R performs exceptionally and is on a par with that found in the D800 models. Given the Sony’s small size, low weight and outstanding sensor performance, it’s one of the most intriguing and compelling new additions in recent times.”

And here are more brand new A7r tests:

Cameras.reviewed published their first impression review:

“At first glance, it’s really hard to find fault with the package Sony has put together. Admittedly, the company’s lens roadmap is very ambitious, and Sony has a spotty track record when it comes to actually getting its high-profile releases on store shelves. But if the launch goes smoothly and the A7s are well-received, Sony has a real chance to steal Canon and Nikon’s thunder.”

Sony A7R vs Nikon D800: which full-frame camera should you buy? (Digitalcameraworld):

“It’s easy to scoff at a comparison of a new, as-yet-unproven full-frame mirrorless interchangeable lens camera and a full-frame DSLR that has set the benchmark for sensor performance.
However, it becomes less of a laughing matter when you consider that the Sony A7R delivers the same sensor resolution of the Nikon D800, but in a camera body that’s cheaper and easier to carry (with the right lens), and comes with a wealth of tech that makes it easy to take and share photos.”

What We’re Finding Wrong With the Sony A7 and A7r So Far (ThePhoBlographer):

“When it comes to focus peaking, the accuracy isn’t perfect. Unfortunately, when we use full auto focusing, spot focusing zone, multi, etc. And based on the way that someone would compose a scene, the focusing can be hit or miss. Metering: we’ve found that the system underexposes by a full stop. We’ve been using the A7r a lot. It’s by far our favorite for the image quality that it can deliver when you nail the image absolutely perfectly. However, nailing that image is tougher because the sensor amplifies the slightest issue (such as camera shake) and any other problem by ten fold. We almost feel like anything we do with it requires a tripod.“
