Like I said in the previous post, if you get the focus right, you cannot complain about image quality (provided you get a good copy of the lens of course). I must admit, I was shooting constantly with the two system I took and I did have a lot of misfocused shots. I deleted a lot of images from this outing. But, the more I used it, the more I knew where to focus to get in focus what I wanted in focus. practice makes perfect the say, and I personally don't shoot often enough to reach perfection with these systems.
