Thanks for the help, everyone! I didn't get anything out of the ordinary with the focusing sheet, and I've noticed some shots are getting a bit sharper now, perhaps as a result of my moving the lens a bit further away. So that's good--the images are looking better.

The viewfinder, however, never seems to be in focus. I've taken a look through it once I get a very sharp shot on the LCD (after zooming way in), and the viewfinder is fuzzy... when I get the viewfinder in focus, the result is out of focus. I have tried changing the diopter setting, but I can't ever make it as sharp as when I focus by hand (and then find the shot to be out of focus)... it's always at least a bit off...

That still sounds like Front Focus/Back Focus. I'm surprised that the focus test chart didn't show anything.

I can try using the chart again, but I'll have to switch lenses... the one problem with the 180mm is that I couldn't fit much of the chart in the frame--just the center text and a few of the lines on the side.

To use the focus test chart, you need to shoot at it at a 45 angle. The camera focuses on the focus target in the center of the chart, and the scale shows the amount of front focus/back focus. If you left the camera on the copy stand pointing straight down at the focus test chart, it wouldn't tell you anything. If you take the camera off the copy stand, you should be able to get as close or as far away as you need to.

I did angle the chart... it may not have been perfectly 45 degrees, but it was close. I used the copy stand because I don't have a tripod and it was my only shot at a steady image. Unfortunately, even 3 feet will only get me a small portion of the chart with my lens (on the flip side, that's great for closeups )
