I just returned from a week in the high country in Colorado, Using the A7r and the A6000. I initially thought the shutter vibration problems was a non issue, but after seeing it myself and reading multiple articles, I found this to be irritating. I do not want to have to shoot at 1600 or above to get exposures above the affected exposure times range during the day--all the time. In addition I struggled with the limited DOF that comes with full frame sensors--it was hard to get everything sharp, near to far I decided to use the A6000, and put the A7r aside and give it a workout.
I found the image quality to very good, especially when using good glass like the SOny 10-18 zoom.-- I got many razor sharp images, excellent DOF, and very good colors. The camera was not perfect or as accurate and the A7r image colors, but it got me to 90-95% the way in my judgement. The noise level were very small and less than what I was getting with A7r set to 1600 -3200.
WHy should I have to deal with Noise on every image taken in bright daylight with an expensive camera to avoid the shutter vibration problem.
Once I customized the buttons, the camera was a pleasure to use and I could concentrate on image making without the above issues with the A7r noted above lurking in my thoughts and interfering with the creative process. I realize I will be giving up a small amount of IQ, but for my type of usage and print making, the compromise is acceptable and small. I also enjoyed the ability to get many excellent hand held images
As a result I am seriously considering trading in the A7r and getting excellent zoom lenses for the A6000 and getting a second body.
If you can I suggest renting, testing and judging for yourself.
