I donīt know if any of you try to do any job where vertical lines are important? Recently I was shooting some vertical lines in the facade of a buliding and I find out that: at the corners of the frame, lines were not vertical at all. They curved towards the centre of the image even with a 70-200 2.8 L -IS lens!. With a wide angle lens is very noticeable. You see this effect through the the camera and at the final print.
Does any of you have this same problem? I tested 2 bodies and have the same problem. At the store where I bought the camera told me that this a problem they have been experiencing with other cameras and different sensors, and is a problem of the lenses, not the camera (Eos 1 DS Mark II)..Perhaps.. but what will happen to anyone doing architecture photography.. work with photoshop to get rid of the problem!
How can Canon with this 7,000 Euros camera permit this terrible effect?? I donīt believe it.
Is it there any software that will get around this problem?
Thanks
