The lightmeter does not seem to work, it did a few days ago. I tried a new battery. In short I don't need it, got another film camera. Lens is fine, comes with filter. Camera still works at 1/1000, 1/90 and Bulb without a battery, so that's more than you would get with a Holga or Diana.
I now figured out it's the ISO dial, might bring it in to a repair shop to get it fixed, seems an easy fix. It's giving a reading again, but the ISO value needs to be set with a work around and checked with a meter/ other camera/ really good guess.
