I've only tried Industar-26 and Industar-69 on my mirrorless Sony. The 26 works great, though it gives you a 75mm equivalent on a cropped sensor and cannot be used when you want some wide FOV for your picture.
 
While the 69 taken from a half-frame camera gives you somewhat 40mm and is generelly okay, but... It either has too poor lens quality or its thread needs to be machined just a little bit deeper to give you proper focusing to infinity on a longer focal lengh.  
here's a shot made with i-26
