The X100T’s Electronic Shutter: 1/32000s In 1/15 | Nico Janssen

One of the selling points of the Fujifilm X100T, besides being a gorgeous camera that improves on its predecessor in so many ways, is the new Electronic Shutter mode (a feature that’s coming to the X-T1 as well) which enables shutter speeds up to 1/32000s, which is a ridiculously short amount of time. This is possible because the camera is able to turn the sensor on and off that quickly. While normally the camera would turn the sensor on, open the mechanical shutter, close the shutter, turn the sensor off and then read the data, now the mechanical shutter remains open and the sensor is turned on for, say, a ludicrously short amount of time. However! If you’re imagining that all the entire sensor’s switch is flipped on and off to take a picture, you’d be mistaken. Instead, the camera turns on and off each line of pixels in the sensor, one at a time, from the top of the frame to the bottom. So the bottom line of pixels actually records the image a little later, resulting in an effect called rolling shutter. This can be pretty funky, as you can see here.So how long does that actually take? Since there was no official documentation on this topic that I could find, I enlisted my boyfriend’s help. He retired to the attic he calls his Engineering Laboratory and reassembled components he’d been tinkering with for a portable light modifier I’d requested, wrote some code, and an hour later our experiment could start. Here’s the result………
