X-T2 manual shutter speeds

[TSmith]

Sometimes when I shoot on manual the shutter speed will change by itself. I was shooting some volleyball last night. Poor lighting so ISO 12800. 16-80mm @ f4. Shutter speed set at 1/500 sec. Every now and then it would be at 1/400 sec even 1/320 sec., all the while the shutter speed dial would be still set to 1/500 sec. I rotated the shutter speed dial back and forth and it would go back to 1/500 sec. Has anyone had this happen to them?

It sounds like you may have your front or rear command dial set to work with the shutter. Probably the front dial. If you roll the dial one way or the other, you can get the in-between shutter speeds, that is the shutter speeds in-between the ones listed on the top shutter speed dial. In between 1/250 and 1/500 are 1/320 and 1/400.

I'll check this out the next time I use it in manual control. Thank you.

I had this problem shooting two different X-E3's (hardware similar to X-T2). When set to fixed aperture, fixed shutter speed, and fixed ISO, the shutter speed would very often be something other than its manual setting. Exposure was frequently way off, and the speed to make the shot was noticeably slower, which was very unfortunate since these were action jobs.

Rather than spend too much time under the hood trying to out-think firmware code, I tried using auto ISO, and it's all good now. The ISO varies to no detriment, response is improved, and I get the aperture and shutter speed I selected.
