I had a Nicca IIIs with the Nikkor f2/50mm. Had Youxin do a full CLA, new curtains, etc. I thought it handled very well, the mechanics and fit and finish are first rate. Unfortunately I just can’t deal with the squinty viewfinders all these old rangefinders have anymore, and I didn’t want an accessory one on top of the camera. No parallax correction either. I have a gorgeous Contax IIa but I always reach for a later model rangefinder with a big viewfinder when I go out.
