Ok, so after much deliberation, I bit the bullet and purchased a Minolta MD focal adapter for the A7R. One thing I noticed right away was the heavy vignette effect the adapter had, which was something not present on the non-focal adapter. I had to use the crop feature on the camera as not to get the vignette effect. My main question is... which is better? Having all 36mp without the Focal adapter or 24mp with the focal reducer II? Thanks for the help.
