First, I would like to apologize for keeping it silent for more than 2 hours on a Friday night...some of you states side may forget that here on the island we are some 5-8 hours ahead of you, but anyway.
Anyone who follows this forum, knows that since the first post regarding the "centrefold" issue, I have been passing on any information I had that could have helped, in both directions.
Any current user who contacted us with this issue, has being taken care of in the best possible way under the circumstances, either on or off-line.
There is no magic here and our people are working hard to find a solution, as crude or as elegant as it may be and we are doing our best to keep these customers informed with any updates.
To put things into perspective, off the several hundreds of Aptus 75 backs that were shipped so far, there are only 15-20 cases world-wide that are currently being dealt with. This is by no means to diminish any of these cases.
The ultimate solution has yet to be found. This may turn out to be a design update at the sensor level, or a firmware/ software fix. We currently have several faithful customers helping us in testing a few of these options.
There is a Leaf Custom Gain Adjuster utility that allows the user to correct any effected file. This app not only fixes the "Centrefold", but it also addresses any colour shifts and lens fall-off/ vignetting. This is not the most elegant and straightforward fix - more likely serving as a test bed for a new algorithm later to be implemented into our capture software.
If at any point down the line, a change in sensor design comes up and resolves this issue, this will of course be everyone's most desired solution.
Wide-Angle photography seems to be the most challenging for digital devices, most certainly when non retro-focal lenses are in use and shifts are being applied.
All digital backs suffer from it to some extent, in one way or another. The solutions from the manufacturers are different to one another, some work better than others.
So at the moment, if one is to choose a back for this type of work. The Aptus 75 is still one of the most capable of producing great results. It may require additional steps to achieve that, but this is, as I said before, a temporary measure until a final solution has been set.

Please note that I was never appointed to represent Leaf on this forum. I have started contributing several months ago out of personal interest.
If it turns out that I have to take the fire here, then be it, but I would appreciate it if the discussion can be kept on a professional level, saving any personal attacks. I'd also appreciate it if anyone pointing fingers could post under a real name, makes the conversation allot more comfortable.
Have a good weekend
