Got a brilliant gift from my grandmother. It's a Hasselblad 500 C that she found in a camera shop. It looks to be in relatively great condition. This is my first MF camera. I'm used to 35mm only. Can anyone tell me anything about this camera, and Medium format in general? Does anyone have a link to an instruction manual or something similar on the net for this camera? All these controls controls are new to me. Also, what are my lens options with this camera? How wide can I go? I'm excited.
