You can, they're the same media. But the question would be "why bother?", when the price of standard SDXC cards aren't exactly wallet-melting. Agreed with the prior post citing issues of fitment inside the adapter having the propensity to cause issues. I just don't trust it in the same way as a card designed to fit in that slot, you know?
You're right, the phrasing of the question is still confusing me, lol.
So, you're right. When shooting video I usually (and probably obviously) just select my framerate in settings and then double my selected shutter speed using the T(time) selector on my wheel, then fine tune to whatever I want it to be using the command dials. It's really not that big a deal for me to take the extra few seconds to select the shutter speed, but everyone has different degrees of need in this regard, I suppose.
The issue I see with making it automatic in settings is that the amount of users with this particular need is probably very low. I'm personally all over the map in video depending on the scene in question and not always using a specific framerate AND shutter speed every single time I shoot video.
Are you sure?
What you read on the top of LCD is only the video frame rate, not the shutter speed. It's completely different. The shutter speed is shown below, if you put 180 on the dial, the shutter speed is at 1/180th even the frame rate is at 24 or 25 or 50.
