I love the X-T2, it's such a great all round camera and very capable of handling pretty much anything you through at it. Video wasn't really something I expected to be doing with it, but it happens now and again. I had a video shoot at the weekend with the X-T2 and I ran into a potentially disastrous problem. Thankfully it's something that could be easily fixed in the next firmware update.
WHAT'S THE PROBLEM?
With the latest firmware update (v2.10) for the X-T2, we got the ability to set one of the front or rear command dials to control ISO. Fantastic! Here's how to:
Go to Setup Menu (the spanner) - Button/Dial Settings - ISO Dial Setting (A) The options are Auto and Command. Choose Command. Set the top plate ISO dial on the X-T2 to A. Now ISO can be adjusted by either the front or rear command dials. The Command Dial Settings Function in the same menu allows you to choose front of rear dial.
Shutter Speed (front) F. (rear)
With this configuration, the back command dial does nothing (unless you have a lens attached that doesn't have an aperture ring, like the 27mm). Both ISO and Shutter Speed are assigned to the front command dial and you toggle between which one is active by pressing the dial. The problem is that one of them is always live and can be knocked off easily.
F. (front) Shutter Speed (rear)
With this configuration, shutter speed is changed by the rear command dial and ISO by the front. The upside is that the ISO can be changed using the front dial and then locked by pressing the command dial. Unfortunately the shutter speed is always live and so easily knocked by a third stop or two, causing rolling vertical lines that cannot be fixed in post. Video footage is useless if this happens. I must have knocked my shutter speed of at least 6 times at the weekend and will be taping the rear dial down from now on.
THE FIX
F. (front) Shutter Speed (rear) is the ideal choice in my opinion. When shooting video, I like to chose my aperture on the lens and select my shutter speed on the top plate SS dial, then make minor adjustments using the rear command dial (for instance: Set the top plate SS dial to 1/60th and then adjusting the SS to 1/50th using the rear command dial when shooting at 25 fps).
update the firmware to allow the rear command dial to be locked by pressing it (just like the front dial for ISO), we could lock both ISO (front dial) and shutter speed (rear dial).
No more moving dials by mistake!
