I hope I am correct in starting a new thread for this, because my case was so specific and I could not find answers in a forum search.
After recently purchasing a GH2 body, I just got a Sigma 28-80 AF Macro lens with a Minolta Maxxum SLR body. The manual focus is very noisy, and if I hold the lens ass-end upside down, it rotates out quickly. Seems pretty shoddy, but I think it would be good for some static extreme close-ups. I also won an auction for a Nikkor 50mm f/1.8 manual focus lens, which I haven't received yet.
The question is, what mount types are these lenses? How do I find out that info? Nikon has a bunch of mount styles, and this is older glass. The Sigma, I don't even know where to start. All searching has been fruitless or just not exactly sure.
Does anyone know this information? I need to find adapters for M4/3 or GH2. Was thinking of RainbowImaging or Fotodiox brand, unless someone can think of a more reliable choice. Something under $30 really.
Sigma = $10 (with slr cam, infr flash, bag, etc)
Nikkor = $99 (*much* more important to me)
I have two pictures, one of the Nikkor and one of the Sigma.


The ebay seller couldn't even tell me what mount the Nikkor was. And the sigma in the pic is not mine, looks similar, but mine doesn't have aperature control. Any help would be appreciated. Thank you.
