Hi Last week during a reportage, I shot bursts from about 5 fts with one of my two X-T5s, for a total of about 100 photographs. I had mounted a Fujinon XF8mm. Everything seemed to proceed regularly without any sign of problems. When looking at the sequences in the car I realized that many photos were completely black, that is, as if I had taken with the cap in front, alternating with some perfect ones and others completely white without any detail. Back in the studio I loaded them onto the Mac and noticed that of a sequence of around 100 photographs, 49 were completely flawed, that is, almost all of them were completely BLACK and some were completely WHITE. The problem was present both on the photo of the Slot 1 card (RAF) and on the Slot 2 card (JPG) in unison, so much so that I discarded the hypothesis that it could be a problem with the memory card. So, to recap: the errors on the 49 offending photos are exactly the same, for both cards in RAF and JPG. After turning the machine off and on again, it started working perfectly again, so much so that in the following days I carried out other jobs, even with gusts, without any problem. Obviously I am waiting for a response from the support to which I sent the offending sequences. I would add that if I analyze the EXIFs of the BLACK or WHITE photos, the values and data that appear are completely normal, that is, they report exactly the same information as the photos that came out well, as if nothing had happened. 1) Before each job, I always format the cards in the machine, with the specific function that can be called up from the menu and quick keys of the XT5 2) The XT5 has Firmware version 2.03 3) The Fujinon XF-8mm lens Firmware 1.00 The problem has manifested itself, for now, only once, intermittently, that is, some faulty photos alternated with perfect ones. In the following days, on the advice of the assistance center, I put on the intervalometer and shot the camera until the card was full for a total of 1600 shots. No problems, everything is fine. What do you think about it? Has anyone had this problem?

In manual, exposure compensation is meaningless and the dial doesn't do anything. The exposure compensation display on the rear screen and in the EVF however changes its purpose slightly, and effectively becomes an old fashioned light meter / exposure meter. As you move the camera, it changes dynamically showing you how over/under exposed you are. It is not doing anything active - not changing a setting - simply passively showing you the result of your manual settings of F/SS/ISO you have set on the resultant exposure. You do not want to disable this. Manually change F/SS/ISO until the exposure comp scale reads 0, and you will have a perfectly manually exposed picture. You can, of course, use it to accurately over/under expose by thirds of a stop, depending on your artistic intent.

Not as such. But depending on the precise problem you are suffering from, there may be workaround. In normal shooting operation, pressing the front command dial button cycles between three functions - which you can change. If you are inadvertently switching between say aperture / exposure comp / and ISO - which I think are the default settings - you can simply set the second and third functions to 'none'... Use 'Spanner'->'Command Dial Setting'->'2'->'none', and 'Spanner'->'Command Dial Setting'->'3'->'none' Now the front command dial does nothing in normal shooting operation.

Dynamic range settings of more than 100% cause the 'gain', i.e. ISO, to be lowered locally in bright areas to reduce/prevent clipping and thereby 'protecting your highlights'. SO it does affect RAW. Most other settings only affect RAW processing i.e. the JPEG. Grain affect does not affect the RAW image data, but it stored in the RAW metadata. Beware - it is difficult (arguably impossible) to 'look at a RAW file'. When you try to look at a RAW file, you are either looking at an embedded JPEG thumbnail preview, or the software that you are looking at the RAW file with is processing the RAW file on demand to generate a JPEG that it is displaying on the screen. Depending on the software, and/or its settings, it may be looking at the embedded metadata and taking the original camera settings, i.e. grain affect, into account.
