Fuji x1t jpg compression is too serious.

the absolute ISO of Fuji x1t should not be too high. Another estimate is that the aperture is very small. If the aperture is large, the ISO and shutter speed will also increase. If the aperture ring is A, the aperture is 5. 6 can't turn either.

the two main parameters are the external intuitive pulsator. When the lens rotates the aperture size, the upper pulsator rotates the shutter speed, and press Q, there will be ISO. This problem will occur when the camera is in poor light. However, the fully manual camera is suitable for walking to shoot fast films, with high film output rate and in-focus in any environment.
