I've considered buying some before because I'm pretty sure they would work for 4k on the NX500 given the camera's extreme 2.4x crop and all, some of them look like they'd be pretty sweet to play around with. Has anyone tried this? C mounts won't focus to infinity on the nx500... I know... I tried. They are cool macro lenses on it though. 38 minutes ago, kidzrevil said: Is there a thread on here that shows all the c-mount lenses that can cover a m4/3 sensor ? I like the look of these lenses but I shoot stills as well so it would be dope if there was a list setup somewhere I don't think there's a list on here for micro 4/3... Other than the c mount list for the BMPCC. Might be a good place to start. Or try Flickr. Parker and kidzrevil 2 Quote Link to comment Share on other sites More sharing options...
Super Members Mattias Burling Posted June 23, 2016 Super Members Share Posted June 23, 2016 BTW, from shooting Leicas the last months I can say I really dig the Voigtlander M lenses. My favorite by far due the to the quality/€ is the 28mm f2.0 Ultron. Gets you really broad and nice zones for zone focus with a pretty wide aperture and the focus is buttery smooth. Not like the 15mm where everything from 0.7m to infinity is in focus at f4.5, but still. Here is a sample, again using T-Max100.

tweak Posted June 23, 2016 Share Posted June 23, 2016 @mercer @Mattias Burling 12.5 Fuji only covers 4K on GH4 not 1080p. Also I feel the 12.5mm is the least impressive of the Fuji line up of lenses sadly. It's still however a decent lens. Quote Link to comment Share on other sites More sharing options...

Hanging Around Down Town by Mattias Burling, on Flickr I had the 35mm f1.2 , 50mm 1.1 & the 70mm voigtlander, super sharp & beautiful OOF rendering. Too bad I could only use em on e mount cams Quote Link to comment Share on other sites More sharing options...

I like it on the BMMCC though, but I would like it better with a different focus distance and if it had a better focus ring. The way the entire front of the lens turns feels odd when pulling focus, but the IQ is nice. Quote Link to comment Share on other sites More sharing options...

It covers my sensor completely. 7 hours ago, kidzrevil said: I had the 35mm f1.2 , 50mm 1.1 & the 70mm voigtlander, super sharp & beautiful OOF rendering.

Preforms way over its price. Super cheap on the used market as well. Quote Link to comment Share on other sites More sharing options...

tweak Posted June 24, 2016 Share Posted June 24, 2016 8mm does for sure, but good luck finding one or modifying it. 9mm wont, it's 2/3 inch. mercer 1 Quote Link to comment Share on other sites More sharing options...

If so, what did you use for a spacer when you modified it? Quote Link to comment Share on other sites More sharing options...

The 25mm is easy to modify (probably the easiest), you can just dremel or file a bit off the corners of the back of the lens until it seats far enough down in the adapter..

Super Members Mattias Burling Posted June 25, 2016 Super Members Share Posted June 25, 2016 I dremeled my adapter instead, keeps the lenses looking nice. Quote Link to comment Share on other sites More sharing options...

That's only possible for some 25mm, others it is impossible to take enough off the adapter to reach infinity. 12.5 and 75 both need no modification if you have the correct adapter. 50mm needs about 1.5mm taken off the back of the lens with a thin adapter. 8, 17 and 35 are all very hard mods and need a lot of work.

But with the 25 and 35, you don't need to dremel or file anything. For the 35mm, you just unscrew the back plate and glue the adapter to the lens. For the 25mm, you unscrew the back plate and then use some kind of spacer that will sandwich in between the adapter and the aperture ring... Very easy to make it clickless as well. I just haven't found a good material to use as a spacer. Quote Link to comment Share on other sites More sharing options...
tweak Posted June 25, 2016 Share Posted June 25, 2016 Depends if you want it to work properly/ be proper or not . If just glue it together you can't change to different mounts. Edward K does an amazing job on these lenses. 8, 17 need more work than removing the rear. 25 and 50 0.7 also need a lot of work. Mine are also all click-less.

Super Members Mattias Burling Posted June 25, 2016 Super Members Share Posted June 25, 2016 I have yet to come across a lens where it wasnt enough to dremel the adapter. Accept for tevidon where you switch the mount instead. Quote Link to comment Share on other sites More sharing options...

Mine are also all click-less. I can easily get infinity focus on the 25mm by taking off the rear ring and using a Fotasy adapter. Even without the spacer it works. http://www.getdpi.com/forum/4-3rds-cameras/13547-czj-tevidon-versus-fujinon-cctv.html#post176111 Quote Link to comment Share on other sites More sharing options...
