<p>Hello!<br>
Now, I am not posting this to seek help, because I am already pretty much sure that the only decent answer to my problem could only be "repairs are not worth", and I'd be keen on agreeing. However, I am sharing this because I find my old NEX-5 camera misfunctioning in a really bizarre way and I just wonder if you have already seen something like this.<br>
Well, you can see the darker strip in the right. I photographed this target onto a black curtain. <br>
The first thing that popped up in my mind was: some trouble with the flash synchronization speed (because yes, I was using flash: to be precise, some external Elinchrom units piloted by the small on-camera flash). However, this is not the case. Apart from the obvious fact that I was using a slow enough speed, as you can see the strip is not black - it is just darker (and there was not enough ambient light to show the target without flash light).<br>
But, there is more to it. I have done some experiments that make this defect more intriguing.<br>
First: it only appears with vertical shots! It sounds bizarre, I know. I suspect, in fact, some sort of interference with the sensor that tells the camera whether it is in vertical or horizontal position.<br>
Second: it only appears if I am photographing something very dark. You might object: "no, it is just that the band is more visible if the object is dark!" Well, no. You see the white strip of fabric: I cannot see on it any discontinuity of illumination, yet I have tried (even on the original RAW file) to increase locally the contrast. Nope! The dark band only appears if I am photographing something that would result dark or black in the photo.<br>
Finally: it only happens if I am shooting with flash! If I photograph something very dark/underexposed, without flash, I won't have the band.<br>
So, to recap: dark things, photographed vertically, with flash.<br>
For the moment the only solution I found is shooting in horizontal position :-\</p><div></div>
