Adapter for Samsung NX to use Canon/Nikon lens

[Elvis Peckeliunas]

Hey, Samsungers!

So, i used these two cheap adapters:

Canon: http://www.ebay.com/itm/Canon-EOS-EF-Lens-to-Samsung-NX-Mount-Adapter-NX5-NX10-NX100-NX200-NX300-NX1000-/191627462262?hash=item2c9de30676:g:2FAAAOSw8vZXNFgW

Nikon: http://www.ebay.com/itm/Roxsen-Nikon-F-mount-AF-S-G-Lens-To-Samsung-NX-Mount-Adapter-NX5-NX11-NX20-NX200-/400912526863?hash=item5d583fae0f:g:9rgAAOSwv0tVRvyt

And i'm not satisfied neither from these two. Canon adapter isn't stiff with body, it moves from side to side 1 millimeter when i rotate focus. Nikon with my Sigma 18-35, fastest aperture is about 2.2, i can see that's closed a little bit and when i rotate more than it should be, then aperture is opened, and also it isn't fit perfectly, feeling looseness.

So, friends, did you discovered some really nice adapters and can recommend to others? I wanna that lens would be stiff as native ones :D

I use the cheap K&F Concept EOS-NX adapter, it's 21,- EUR on Amazon. I use it very often, even with big tele lenses like the Canon 300mm F2.8 and it works perfectly. All Canon lenses are still stift after one year of use. I hope this helps.

I second that, K&F have been very nice to me, and not very cheap, but not expensive at all either.
