Some help with adapting different lens focal lengths to Micro 4/3...
Hey, it's me again. Kid with the Pentax and the winter movie, except the movie never got made, and the Pentax is dead. I've decided to invest in the Panasonic GH4, because, well, I think it's a good investment. I'm not here to debate over the camera choice itself, so don't try to bring that up. :)
I currently have 3 lenses, with adapters, that I plan to use on my GH4 once I buy it. Just some cheap vintage glass I found on ebay, since I found a couple people on here saying just to do that. Don't worry, I won't stick with them forever, they're just to get me up and shooting.
My deal is, I need help converting the lens focal lengths to micro 4/3, so I know what my actual focal length is, so I don't end up buying the same (cheap vintage) lenses later.
My lenses are:
Minolta MC f1.7 at 55 mm Prime for Sony Nex
Minolta MD f3.5 at 135 mm Prime (I'm assuming for the same mount)
Industar f2.8 at 53(?)mm for M39 mount
All have the correct adapters for their respective native mounts to Micro 4/3. So now my question is, what are my actual focal lengths? If you can get me answers for each one, and/or direct me to a page that has some kind of conversion tool/table, it would be super appreciated.
Thank you all in advance.
