Neuro - Thanks so much for the reply.
Yes - it is the green characters to which I am referring. They are not just dark by the way (I have just tried the camera in complete darkness and there is isn't even a sniff of a green character)!
I had sent it in as the camera had been behaving a bit oddly. The errors I mailed to them at the time were:
1) The camera switched on and was being used. It suddenly became unresponsive to any button being pressed on the camera. The top LCD display was showing as off. (To clarify, the camera was switched on and was not asleep.)
I took the CF card out and then put back in. The top LCD display then came on but all buttons were still unresponsive.
The large battery was taken out and immediately put back in. All buttons were then responsive.
2) Focusing has been erratic:
a) On occasion the camera will not focus, becoming totally unresponsive to the focus button. When this happens, the focus button needs to be pressed a few times to get the camera to begin to focus.
b) At times focussing is pin point accurate. At other times the focus point is completely out of focus, although other areas of the photograph are then pin point accurate.
c) On occasion, the whole image is blurred.
d) On occasion, exposure is way off - very overexposed images. This can happen in the middle of a burst of exposures (where other images are correctly exposed) or on one shot.
Initial lens used Canon 24-105mm IS L. Results repeated with Canon 70-200mm mk II IS L f2.8 and Canon 16-35mm IS L f4.0
Until the above issues, the camera had been superb. Thankfully, it is under a repair warrantee.
So you think they have botched the repair……..?
