Please don't reply if you don't own the camera. Thanks.

Yesterday I noticed that my center focus point is not directly in the center of my spot metering circle when I look through the viewfinder. It's a little bit to the left. When I check my focus point in Zoombrowser, it confirms that where I tried to focus was actually focused a little to the right.

Upon checking other points, it seems all the points in the viewfinder are shifted to the left of where the camera is focusing according to Zoombrowser.

My question is, is your center point right in the middle of your spot metering circle?

I made this picture to kind of show how it's shifted. The red is where the focus points in the viewfinder are compared to the black which is where they should be. I'm not a paranoid whiner. I'm just wondering...

... removable screen cameras. Simply pop your focusing screen and reseat it. there is a bit of play in the screens in the frame that can make the circle on the screen appear offset.

That's great news. Now, if I can only figure out how to do that. Thank you.

The focusing screen being a little off center makes sense, but how do I account for the fact that the focus point that shows up in ZoomBrowser is to the right of where I had focused, which makes me think the box that lights up in the viewfinder is actually not alligned with the af sensor? Hmm.

Ben, as best as I can tell, mine looks to be right in the center. I looked at it extra carefully after reading your message.

The 1 series may be different, but on a 5D, 20D, etc. there are usually two plates. One is the focusing screen that has grid lines, micro prism , etc. This plate is user changable. The other plate is the Superimposition Plate (SI) that is between the focusing screen and the pentaprism. The SI plate is not designed to be user changable and contains the little focusing rectangles. Aligning this plate requires a screwdriver ans/or a small pick.

Thanks for the info, Jerry. I'm pretty sure that it's the SI plate you describe that's out of alignment because when I focus on an object, then move left and right of it until I lose focus, there's more "play" on one side than the other. I'm not sure if it's a big deal or not, but for $4500, I really don't like it.

If it is the in the top of the prism, its a simple alignment for a Canon service center.

I don't blame you for not liking it. It should be an easy fix. I pulled the SI plate from my 5D and it took about 2 minutes.
