Samsung is certainly an ambitious company, and its efforts have paid off with a global mirrorless market share that only falls behind Sony. It's done some experimentation (DualView, Galaxy Camera) and made some more conventional cameras (NX30, NX3000). With the NX1, Samsung is trying to appeal to the enthusiast market, with a spec sheet that surpassed my expectations. And, based on my initial experiences with the camera, it's done an impressive job.
The first time I picked up the NX1 it had Samsung's beastly 16-50mm F2-2.8 premium 'S' lens attached, which weighs 622g (1.4lbs). After taking that off, I found the camera to be quite light and well built. That is, with the exception of the various dials, which feel cheap. The NX1 feels just right in my hands, with a perfectly sized grip and easy access to the two main control dials. I'm less of a fan of the four direct buttons that sit above the Nikon-style drive switch on the left of the viewfinder hump, for a few reasons. For one, they're small and out of the way, and I found myself having to move the camera away from my eye to use them. The dial on the bottom is nice, though I'm not a big fan of the locking mechanism.
Actually taking photos is a pleasant experience. The camera starts up fairly quickly, and focus speeds are impressive, though I'm not convinced that it's the fastest system out there (those claims are usually made under very controlled conditions). Given the NX1's Hybrid AF system, which has phase detect points over 90% of the frame, I expected it to be pretty good at subject tracking, and when fooling around the office it seems to work well. The NX1's 15fps burst mode is quite impressive, as well.
Both the OLED display and EVF are fantastic, and the user interface is very pretty. The touch features work as you'd expect, and I prefer using them for navigating the menus, as using the directional buttons is a bit sluggish.
Video is a huge part of the NX1's story, with 4K support and the use of the new H.265 codec. The usual manual exposure controls are there, as well as focus peaking and zebra pattern, as well as mic and headphone ports. It's too early to evaluate video quality (and photo quality, for that matter), but we're looking forward to it - right after we buy that 4K TV.
Samsung has made improvements to their already elaborate Wi-Fi system with the addition of 802.11ac and Bluetooth. Unfortunately I wasn't able to try them out, but the idea of using Bluetooth to speed up camera-to-smartphone pairing is intriguing.
The NX1 finds itself amongst some fierce competition, both from mirrorless and DSLR cameras. Olympus, Sony, and Fujifilm have established themselves as leaders in the mirrorless space, and all offer excellent enthusiast products. And let's not forget about DSLRs such as the Canon 7D and Nikon D7100, which have a similar price tag and also have a lot to offer. On paper at least, the NX1 surpasses those cameras in terms of continuous shooting speed, movie recording, and Wi-Fi functionality, while image quality and AF performance remain to be seen.
While I don't believe that the majority of enthusiasts who are already invested in other systems will suddenly sell everything and jump ship to Samsung, those who own a more basic ILC with a lens or two may well find the NX1 to be a very compelling product, if it lives up to its significant promise.
