I have been getting some weird reddish dots and blobs in most of my shots with my old Yashica Super FX-3. They seem to appear with any lens and using film rolls with different ISOs (200/400), and also produce a general loss in sharpness and color quality.
Do you think this can be due to a leak somewhere in my camera body? I used to think that leaks would cause a more "rectangular" while halo, rather than these arbitrary patterns. However, this seems to be the only possible cause as I have tested different lenses and used film rolls with different sensitivities.
