Anyone still using Samsun NX series of mirrorless camera in 2019 ?

OIS on the 16-59 S is a total disappointment. It does not function properly on the majority of copies.

16-50S yes, not 16-59S...

I never was aware of this, also from first moment I engaged OIS.
And I never had that blur kind of shoots, and I shoot mostly manual in hands, with exceptions of using touch AF (my eyes...). Also I shoot in less than a minute, usually turn it on, set F, set time and I mostly underexpose between 0 for video and - 2-3EV for stills, check ISO since try to keep it lowest, all this about 15-20 seconds, set the frame, so I say most of the time in 1/2 minute is done. Well, I'm not a street/sport photo guy...
The shot somewhere above was converted from RAW with IrfanVier no other corrections. It is not original size, but it took me around 30s to shoot somewhere -15C, not quite time to warm up. I do process with LR only when serious work is required.

I did had some blur images with a forest patch in background, where the main color was green (no clear leaves even they were very large - tropical vegetation), but this never happened with other backgrounds.

But the second moment I get the NX1 kit (with 16-50s and power grip) was to "check" BIOS, and to my surprise they were the last, both camera and lens, and I change other settings from "default" Korea.

Checking old DPR threads, seems like the issue was solved with BIOS updates, also you might need a "warming" time which can be up to a minute.
As I said, without some exceptions (green leaves in background), with my operation "speed" of about half minute, everything was and is OK.

Sure, some lens can be lower quality, after all they are made in China not in Korea.
