In what way did you think they were bashing the camera, jules?

We want to be a friendly and helpful forum. A bit of tolerance goes a long way.

You almost seem to be taking the position, John, that since before we had digital cameras and the internet (and hence the ability to analyse and communicate problems such as these), we wouldn't have known about the problems, therefore we shouldn't be making such a fuss now.
Well good on the Internet then
It took a long time for people to become aware that after leaving a film camera for some time the first shot or two would be blurred. Why? Because of the kink in the film where it left the non-tangential film trap on the 35mm cassette. This eventually led to the redesign of the exit on the cassette, but it took over 40 years before it was realised.
Take the issue of exposure errors with M series and earlier lenses - film cameras were the same throughout the 1990s and the digital models have the same problem still. In this case it seems that it's something that cannot so easily be addressed.
So the question was a reflective have we been suffering from BF and FF focus errors for years and just been dismissing it as user error? We've all had less sharp images from time to time...

Add to that the increasingly widespread hacking of camera systems and the ability in later models to fine-tune focus and there could be quite a lot a variables.
I don't know what answer to this there could possibly be, but returning a camera for service people to deal with is one way of hopefully ensuring an accurate result. Otherwise, we may be better just doing our own testing until we as individuals are satisfied.
An example is the firmware upgrade. Some say it works, some say it doesn't and some say it's partially successful. It may be that there are other variables, it may be that some don't test properly, who knows....but in the end all that counts is whether or not our cameras focus accurately.
One thought is that this may never have been any different. No magazines have reported this as an issue, and it only becomes one at very low EV values. Before the internet, this would just not have circulated and it would have taken a very long time indeed for any issues to become common knolwedge. Are the same issues present in AF film cameras?
Unfortunately, waiting for film processing would mean that meaningful testing would be very laborious.

Maybe John will sell you his..?

All in a bit of a state, but working. So now the job of cleaning it all up and we'll see what it's like!

Reviewers are allowed to have their opinions, otherwise they're not doing their job. If that's what the reviewer honestly thought, then those are his or her conclusions.
I have seen truly biased reviews elsewhere and that's another matter altogether!
