Oh, that effort.

I’ve been thinking about putting an MFT mount on my RX100 to use it with more interesting lenses (I have it for the high frame rate capability) but concluded it to be way too much effort and risk.

And then along comes a person with enough determination to build an entire custom case! Truly impressive.

I saw footage someone captured when they modified their Canon 1D to use a PL mount. They then mounted a 17mm, iirc, that in a slow shutter could capture as many photons as my shitty 20mm EF mount could do in a 5s long exposure in bulb mode. The front piece of glass on that 17mm was ginormous. I really wish I could remember the guy's name to find a link. He mounted that camera to the front of a fishing boat down the canyon river pushed by the current navigating in the dark with night vision goggles. The resulting timelapse was glorious.

There was something specific to the body of the 1D that allowed for the proper flange depth of PL lenses that the other Canon bodies did not work for this mod.
