Samsung continues to provide significant FW updates, similar to Fuji.
The latest for the NX1 has significantly buffed up the low light focusing which I considered a weak area.
I have not fully tested it but I already see very good improvement. Enough so that the NX1 will be my main travel camera this summer.
In the old digital days I carried an Olympus E-1.
I replaced that with a Nikon D700.
Then I travelled with a digital Leica, most recently the M9.
When the Olympus EM-5 came out I felt it was more robust, reliable and versatile than the Leica so it became my travel kit.
The fabulous Sony A7 replaced all my micro4/3's gear even though it has a few shortcomings.
Now the Samsung NX1 has pushed aside the A7.
Far better AF, incredible 4K video with 8MP frame grabs, butter smooth 120fps HD video, terrific stills that have gorgeous color and are nearly grain free at low ISO, weather sealing, very good connectivity, this camera can do so much.
For example, just put it on Face Detection and use a wide lens then by holding the camera out in front of me a bit I get wonderful, spontaneous shots of kids and their friends or parents while we are walking, sitting, playing or whatever. At 15fps I usually get at least one shot where the micro expressions are completely charming. I don't have to use the viewfinder or back screen at all.
Or, if they are kicking around a ball, just a few seconds of 4K video will generally provide at least one or two really nice frame grabs that show some peak action. The NX1 has pretty fast and accurate AF during video.
Of course, I also use the single shot mode where I carefully frame and focus for each capture. Even there, the ability to move the focus point anywhere in the screen is a welcome feature.
Highly underrated, the NX1 is, IMO, the best all-around interchangeable lens camera available at any price.
Best,
Bill
