I'm planning to sell some gear very soon, various bits and pieces, so I was taking some pics of them when I thought it might be interesting to show a couple of pics of the camera I use for product shots. Its a 5D2 adapted to the back of a Sinar P view camera. The lens is a Rodenstock Sironar-N 150/5.6 which is quite sharp but gets a tad soft when stopped down to the sort of apertures you need for depth of field but the movement on the Sinar allow you to control the focus plane extremely well so there isn't as much need to stop down.
The camera (shot with Canon 10D and Canon 100/2.8 Macro USM);
A few of the pics shot with it (just a few where the tilt movements came in handy to help with focus plane).
It makes a fair macro rig too. The same basic camera/lens was used for this a while ago;
