Fuji GF 100mm lens question

[felix5616]

I recently purchased a used, mint condition Fuji GF 110mm f/2 lens. When I tested it this morning I had the camera set to electronic shutter, shot hand held and when I examined the shots there was significant bending in the image, not out of focus but severe distortion on all the images. I went back and shot hand held and tripod, the same images but with the mechanical shutter and saw no distortion.  I have included an example. Is this a known problem? Images was captured in RAW format.

The sensor readout of the IMX161 sensor (found in both the GFX/X1D) is really slow, about 1/3 to 1/4 of a second.  Motion blur, bending, warping, handshake, etc.  Hence you should always use the mechanical/focal shutter in every case...

it is known. It is not a problem, necessarily. It is not related to the lens.

Here's an explanation of what's going on:

If you want to experiment, you can produce some interesting effects:
