Fuji xt5 with 7artisans 35mm f1.4

[zoelivrose]

I just got the 7artisans 35mm f1.4 lens for my camera. Problem is, the aperture dial on the lens isn't changing aperture but shutter speed. The aperture is just set at f 0. Does anyone have any idea on what might be wrong?

Hi, if its the manual focus one, there is nothing wrong, I guess, there is no electronic contact between lense and camera so camera cannot know aperture. Shutter speed will adjust according to the aperture you chose if in aperture priority mode.

To go along with this, unless the camera is in full manual mode, the “auto” algorithms will notice sensor changes caused by rotating the lens’ aperture ring and make adjustments to other settings, most likely adjustments to the shutter speed. The f-stop is changing, but not being recorded. Try setting the iso and shutter speed manually, you will have to remember what you put the f-stop setting to though.
