I'm using the acratech L-plate as RRS don't make an L-plate for the battery grip on the A7R yet. It's eliminated any shutter shake either with camera or lens mount. Some pics and comments halfway done my review here:

Very interesting. How does the battery grip attach? Do you have to remove the L plate to attach/remove? For me this might be a good combination; remove battery grip/L plate for handholding, attach for tripod photography, and neither should be susceptible to vibration.
Yes you can remove and attach the grip with the L Plate on if you want. Only thing is if you don't have an extra battery, you'll need to take the plate of the grip to retrieve the battery in the grip. If it was me, I'd just take the L plate off and hand shoot with the grip on.
Is the battery grip vibration fix the way to go for longer than 100mm work, has this been verified? Now all we need is Sony to give a discount to all A7r owners on the purchase of the $299 grip. This would give Sony time to work on the firmware update and quiet most all the vibration talk.
I simply couldn't replicate the shake, even when using my longest, heaviest lens, Contax C/Y 180mm f:2.8, shooting a target 25m away. Following the "shake manual", I tried shutter speeds between 1/20s and 1/120s, and couldn't generate it. I tried portrait mode, and still no shake. I tried my lightest tripod, a very flimsy all-plastic Cullmann, fully extended, and still no shake.
From participating to the GetDPI forum on this topic, it was clear that the shake can happen if you connect your camera and lens to the tripod via a lens collar, which basically leaves the camera free to resonate, and the longer the distance between camera and collar, the greater the likely shake.
Those who, like me, connected the camera and lens to the tripod via a baseplate did not get shake. If the contact surface is large, and rubber-covered, all the better.

As I alluded to before, the other alternative is to shoot at a "normal" speed.
Why you want to shoot a 300+ at 1/100 I don't understand
Only situation for me would be panning for motorsports where I use 1/30 - 1/100. I doubt shutter shake would be an issue for these type of images though, no matter what the shutter speed was.
I use a long lens + camera support made with an RRS Y support and some misc. RRS and Hejnar stuff that would probably help to reduce shutter vibration.
Nice Set up! I had shot some test images using my Nikon 70-200 f2.8 lens with the A7r to test for shutter vibrations when all of these discussions first started. Mostly I was satisfied that I could get very sharp images from this combination as long as I anchored the camera body a little more securely or used the battery grip. Below you will see one of my worst images on the left side with the lens at 200mm and on the right side you will see the same image after running it through Photoshop CC's new Shake reduction filter. This was done with one pass totally automatically by Photoshop. I was skeptical about this filters ability to actually do anything that I would use but after seeing the results I feel that it is capable of totally eliminating the A7r shutter shake. I will have to do more tests, but the first ones seem quite positive. The image on the left was done at a 60th of a second only anchored by the foot on the lens with no battery grip.
My RRS L bracket for my A7r arrived on Friday. I will run some additional tests for vibration with the camera particularly in the portrait orientation probably within the next several days or so in an effort to combat/minimize vibration.

There is a program called Piccure that does the same thing but only for lightroom. I have not tested it to see the differences with photoshop CC. http://intelligentimagingsolutions.com/index.php/en/
Thank you for the url. So far nothing for Apple Aperture.
840 grams sure beats the Nikon 70-200 2.8 that I'm using now at 1.54 kg and 8" long. OSS would be sweet. Seems a little high on the price for an f4 though.
It is 840 grams, has a rather meaty lens mounted tripod arm, and OSS.
The kit FE 28-70 does enable OSS on the A7r. I think some of the older NEX lenses disable OSS on both the A7 and A7r. Don't know if anyone really knows why.

For some reason OSS is disabled for the SEL 55-210 on the A7r. The SEL 10-18, 35mm, and 50mm are enabled on the A7r.
