Also does it Dual Pixel AF through it after conversion or are the electronic contacts completely useless? I've been very lightly toying with the idea of an M50 but only for my Super 16 glass which adapts and matches the 4K crop factor. If it becomes a Super 35mm camera, that means it goes from nearly 3x crop to 1.5x crop with your Speed Booster - which would need a reduction factor of 0.5x!!... Seems a bit of a hefty step? Isn't the Speed Booster 0.71x for APS-C? Which would mean 2x crop like Micro Four Thirds on the M50...

I just base on it on calculation, though I need to test it vs gh5s regarding crop factor to see which have narrow view.

tweak Posted May 22, 2018 Share Posted May 22, 2018 Neither of those lenses are particularly great. Fun to mess around with for a stylised look though if you're after that. (I've had both). Dave Maze 1 Quote Link to comment Share on other sites More sharing options...

Django Posted May 22, 2018 Share Posted May 22, 2018 not to mention i'm seeing some pretty severe spherical abberation from the sample pics of that custom adapter.. usually result of poorer quality focal reducers.. https://www.popco.net/zboard/view.php?id=dica_forum_canon&page=1&sn1=&divpage=3&sn=off&ss=on&sc=off&keyword=부스터&select_arrange=headnum&desc=asc&no=10172 Quote Link to comment Share on other sites More sharing options...

There are some machine vision C-mount lenses that do resolve 4K but they are fairly expensive and certainly not worth buying for the M50. That being said, even if a lens does not resolve the 4K resolution, it can still create a very nice filmic image since you won't notice any aliasing artifacts and there is going to be a gradual decrease in amplitude of the higher spatial frequencies.

Dave Maze Posted May 22, 2018 Share Posted May 22, 2018 I guess the ideal would be Veydra with EF-M Mount. I could do C mount but I’m not seeing C mount veydras anymore on their site. Yeah totally. The vintage look would resolve nicely. Quote Link to comment Share on other sites More sharing options...

mercer Posted May 23, 2018 Share Posted May 23, 2018 @DaveAltizer so is your buddy right... is the 1080p with the M50 really good? Quote Link to comment Share on other sites More sharing options...
tweak Posted May 23, 2018 Share Posted May 23, 2018 I'd recommend the Fujinon CF primes, best bang for buck and look, although some need work adapting them. Some of the Canon and Fujinon zooms for 1inch are nice but they never rival primes from the era really and the best ones are still expensive. C-mount primes in Wide angles are pretty hard to come by (especially so for decent prices). You could go the Kowa 6mm or 8mm if you want a proper wide angle, then pair it with some longer fujinon primes. Quote Link to comment Share on other sites More sharing options...
mercer Posted May 23, 2018 Share Posted May 23, 2018 If you want sharp and vintage, go with Kerns or Zeiss Tevidon. The Kerns should fit in most c-mount adapters, the Tevidons may need to be modified using one of those kits they sell on eBay. But Tweak is right, the Fujinon C-Mounts are awesome. There’s a guy in England that will modify all of them and declick them. Also, I wonder if the old Arri S16mm or Schneider Lenses can adapt to EF-M Mount. I also think the Schneider c-mounts are supposed to be that good. Quote Link to comment Share on other sites More sharing options...
