Well, I’m starting to think this lens have some issues with its shutter. Second time in a couple days that it miss fires when I load it AND after that, the image is super overexposed, like really overexposed. It shouldn’t have been like this. I’ll do a better test just to be sure it is fine. I wouldn’t like to have it serviced :D, a copal shutters are no longer produced so you just need to rely on people with the knowledge to service them.
