Don't think I ever posted any footage samples of the vintage 85mm F/1.2 on the GH2, so here it is if you're curious. Old lenses are a great alternative to getting DOF on a budget. There's a variety of different adapters to mount just about any lens type to any camera. For a list of old Vintage lenses, check out the eBay auctions. Just make sure you choose the right adapter for the Lens you choose to fit your camera body.

Here i'm using an FD adapter without glass to make this 85mm F/1.2 work on the Panasonic GH2. At F/1.2 there's a soft glow, but step it down to F/1.8 and it's plenty sharp. They will never be as sharp as true lenses designed for Digital, but that's the whole allure about them. Sometimes they give off a really vintage feel. Oh and I didn't bring an ND filter out so the shutter speed was quite high on this footage. Might look at bit jittery...
