Yup like kel77 said, the function will comes to black X-T1 via firmware hehehe...
Need to google a little bit about this electronic shutter, about how it works. I'm kinda confused at the 1/32000 speed being not suitable for fast-moving object. There's always new thing to learn hahaha
How amazing is Google?
"Instead of the physical shutter closing, opening, then closing again to control the exposure, the camera simply reads the data off the sensor, one row at a time, and writes that data to memory. The advantages are that it's silent, and there's no shutter induced vibration.
1. The drawbacks are actually quite a few. Because the data is read out one row at a time, as opposed to a mechanical shutter which acts on the whole sensor (more or less) at once, the actual exposure takes much longer, about 1/10th of a second between the readout of the first row and the last. That means the moving subjects have moved during that 1/10th of a second, so they get distorted in the image. For example, if the camera is still, and someone is running in front of the camera, from left to right. At the beginning of the exposure, they are in one location; at the end, they've moved further to the right. So the subject is sort of stretched, left to right, from top to bottom.
Also, electronic flashes have a duration of less than 1/1000th of a second. In some cases, much, much shorter. With a 1/10th second elapsed time, only part of the frame will be exposed by the flash.
Under some lighting conditions (primarily flourescent), there may be some banding. And ISO's are limited to no higher than 1600.
2. I believe you can use any shutter speed, or at least most of the range. How does this work when I said it takes 1/10th second to expose the whole frame? The shutter speed is the effective speed of each individual row, not the total for all rows. So a faster shutter speed will freeze motion for that row, but you still have the stretching effect described above. The holy grail of electronic shutters is the "global shutter," which will read out all rows at once. No one has yet produced a photo-quality sensor capable of this, however.
3. You can't use flash with electronic shutter, for the reason described above."
