This will work, as long as you can make sure the camera only 'sees' your target line, so the measurement lines must be far enough away from the 'target' line. That is why I prefer to have those printed at the sides only, and have ONLY that target line near the center area in my viewfinder. The K3 is probably better at it, but I found it hard to focus exactly on a single small detail with the K10, K7 and K5, when other details are closeby ...
