I’m generally not afraid of attempting to fix things myself - especially if it is a mechanical film camera. With Hasselblad though - which is still by far my favourite setup - I was largely staying away with my screwdriver. But it might be time to step up, watch some tutorials and finally fix some light seals here, a jammed lens shutter there. Anything with Hasselblad on it is too expensive right now, and proper service is far and remote - and also not cheap.
