>>3603081Oh, yeah, forgot that I read about it a while ago. It's 500$ speedboster, so your ef lenses perform without crop on rf body. (actually a little bit of crop stays, going from 1.63x to 1.15x on rf, and a little higher on r)
I don't think that's the wisest financial decision, then again I know that people mount priceless retro zeiss glass to gh5, so I guess someone would find a valid use for it.
