Very well built mount, it feels secure when attached to my fx6 body.
The extending is a fun feature to have as well!
I bought this to adapt an takomar lens to my sony a6400 camera.
It works flawlessly. The extendable adapter reduces the minimum focus distance which allows for very nice macro shots reducing the minimum distance from 1.5 m to around 0.5 m for a 135mm lens.
This greatly increases the possibilities with the lens.
Was looking for a quality helicoid for close up photography with my vintage M42 lenses and this Urth is perfect. Very sturdy, infinity focus and no play.
A lot of M42 lenses have a less-than-stellar minimum focusing distance, so the extension feature is worth getting even for uses outside of macro photography– I've found it super useful for both portrait photography and filmmaking. Plus, if you're like me and gravitate to lenses like the Helios 44-2 and Mir-1B for their aberrations and the way they affect bokeh, having the ultra-thin focus afforded by the extension helps accentuate those features in lighting conditions where you may not be able to shoot wide open. To be honest, I got this one instead of the non-extendable one on accident, but it's definitely not an accident I regret.
