Originally posted by rayallen Dave, it might not be your focusing screen that is tilted. With my K10D I was having a problem with tilted horizons and after doing much testing with a spirit level and a known level subject (metal window sill) and a level camera on a tripod with a levelling base I found that the sensor in the camera is tilted. Further investigation revealed that it is a known problem with some K10Ds. As it was way out of warranty by the time I found the problem I just live with it and fix it in post.So, my advice is to test first to determine just where the problem is.

Thanks, Ray and Paul. Looks like you've saved me from the (probably futile) task of trying to straighten a focusing screen that actually might not be tilted after all.
Since I hardly ever shoot anything with any obvious verticals or horizontals, it'll be easier to just correct it in post when needed as you both say.
Ironically, because almost every photo around here is taken on at least gently sloping ground (and sometimes far from gently), I often have to adjust shots to make the ground seem level when in reality it isn't. But if I leave it looking the way it actually is in real life, it just looks like a photo taken with the camera accidentally tilted. Ah the subtle joys of modern photography.
