Spirit level

Following on from Darkmunk's comment:
I was photographing some finds the other day with the camera pointing vertically downwards, shake reduction turned off. I carefully placed the scale parallel to the edge of the frame looking through the viewfinder. In every single shot the scale slopes to the right. This is with me changing the height of the camera fairly regularly, and recomposing every shot through the viewfinder. I, too, am beginning to wonder if the viewfinder and the sensor have different ideas as to what constitutes "level" Given the sensor can move, it wouldn't surprise me if in some cameras they aren't quite square.
Cheers, Kris.

It is an illusion that photos are made with the camera… they are made with the eye, heart and head. Henri Cartier-Bresson
Lots of film bodies, a couple of digital ones, too many lenses (mainly older glass) and a Horseman LE 5x4.

It's well known that not all sensors are level.
Later cameras may be better.

I queried whether the sensor sat square in a previous post and was assured that it did.
I'll let you know when the level arrives and I've played a bit.

Mustn't forget the Zenits, or folders, or...
PPG entries.

A better test would be to set the camera on a copy stand, then align something with the edge of the frame. I have always had suspicions about the sensor on my K10D as I never had problems getting horizons straight with my film cameras.

Does anyone know what the chances of the focus screen on a K10 being misaligned are?
Tried a quick test with the screen markings lined up along a horizontal spirit level. Both the image and a spirit level on the camera indicate a clockwise rotation to correct the image.
My conclusion is the screen is off not the sensor??

It very often is poor alignment of the viewfinder assembly or possibly screen. The sensor can be positioned fairly well during assembly. Take the screen out and see if you can rotate it a bit.

As your shot shows, the veiw finder frame says "level"
The sensor says "HA HA HA gotcha!"
So with a spirit level we'll see what happens.
edit:
I forgot to mention the cost of postage from Amazon, on a small item £4 is very high!
