mttran -- I can see the first photo is way out of focus, and the second one is sharp. But I don't get what a "focus screen aid" is, or how it improved the AF. You saying you used the "S" screen for the second shot, and it nailed focus, or is there some firmware I don't know about?
I've always been reluctant to install and "S" screen due to slower lenses I routinely use. I understand the S improves MF of fast lenses, but noticeably darkens slower ones, and I need the best light on slow ones for AF and MF.
