Just curious, If anyone having one the affected bodies has actually experienced the problem(s)? If so, what was your shutter count?
As I mentioned in an earlier post I only got the camera in March, but have shot over 20,000 images thus far and I have a funny feeling I may have seen the issue the advisory refers to, but can't be certain.
I have had times when the AF would not lock and the image in the viewfinder was blurry, but I always put the former down to poor skill, and the latter down to bad eye sight (even though I am 20/20), fatigue, a dirty viewfinder or something else. It is difficult to explain, but if you are shooting an important match, you are sweating and/or it is raining etc it is difficult to know what is happening.
If, as I suspect, I did have the AF lock and blurry view finder issue, then it was not constant, but intermittent in that it would come and go, which is another reason I did not suspect the camera.
I will be sending mine to CPS as soon as I am able, so probably in a week or two. Have been told they need it for around 3 working days.
