Hi everyone,

I recently shot a roll of Fujifilm 200 film and noticed some unusual marks/artifacts on the developed photos. I'm trying to figure out whether the issue was caused by a defective film roll or by a light leak somewhere in the camera.

I've attached photos of the camera's edges and seals in case that helps identify any potential points where light could be entering.

Thanks for any advice.
