Hi there everyone, I am in the process of building up a stable of vintage lenses to use on my gh2 (primarily for video). when either the speedbooster or lens turbo or whatever comes out for m43. I want to try to get one copy and then use regular adapters to fit different families of lenses. so as of right now I have all M42 Takumar 28 3.5 Takumar 50 1.4 Mamiya-Sekor 60mm 2.8 Macro Takumar 135 3.5 Vivitar 135 2.8

I am looking to get a zoom range to cover everything as well, parfocal and good iq. so far it looks like some studs might be the minolta 35-70 f3.5 and its brother the 70-210 f4 (although if there are any longer range zooms that don't have the focus and zoom features on the same ring please let me know)

So if I get an MD lens turbo/speedbooster I could then get a m42 to MD adapter and use all my lenses on the lens turbo correct?

Also please feel free to critique my collection and let me know if I have any major gaps you think I should cover. I do have the Panny 20mm 1.7 to fill the wide end, and I will only keep one of the two 135mm's
