Like many of you here, my main goal with the X cameras aren't video recording. But occasionally I'd like to record video. And as I've invested too much in the Fuji X system I wouldn't want to buy other cameras for my video needs. Are there any improvements on the video side compared to the previous X cameras (X100/X-Pro1/X-E1)? I've read that you can somehow change film simulations during video recording. Can you change aperture during video recording? What do you guys know about the video recording features on the X100S? I've preordered the Fujifilm mic; MIC-ST1 for my video needs (the USB adapter is included for the X100S). I hope that I at least can record acceptable video.
