I own the Enna 24mm F4 Lithagon in Praktina mount. It's a beautifully made lens, somewhat uncommon these days. It makes sharp images with sort of a pleasant vignette common on early very-wides - reminescent of the first version of the 21mm Super-Angulon.The CZJ wide angle lenses are all great performers, remarkable given how early they appeared on the scene.
I've recently acquired an Enna 4/24 and need to properly test it. It is a very compact design when compared to the CZJ 4/25 or the ISCO 4/24, so I'll be pretty impressed if it can outperform those lenses.
In fact I'm starting to conclude that many of these early post-war German SLR lenses are underrated!
