Drove across the state today to visit my dad. I showed him my new E-M1. As I was leaving he handed me a bag. It was full of camera gear he picked up from a yard sale that I didn't even know he had. Inside was an OM-10, OM-1 Grip, a Crown Electronic Flash 172 and the following lenses: - Cimko 80-200 F4.5 - Auto Makinon mc zoom 28-80mm 3.5-4.5 - Olympus 35-70 F4 - Mitsunon Auto 2X Teleconverter (which came attached to the 80-200 F4.5). Are any of these lenses worth getting an OM to M43 adapter to use? I realize it's only about $10 to $15, but if the lenses (specifically the 80-200) aren't that great, it's $10 to $15 I'd never find a use for.
