Hi Mic,
Excellent review. Thank you for sharing your work.
On my way to visit one of the 7 (sic!) Sony Centers in my city I passed by a Samsung shop, and
stopped to have a look at the NX500. I spent only an hour and I found it quite impressive. I went to the Sony shop to experiment with the AXP33 4K BOSS videocamera (nearly twice as more expensive than NX500) with money in my pocket to buy one if I like it. My experimenting with the NX500 (for much less money than th price of AXP33) was enough to decide to postpone my 4K camera purchase for a couple of months.
Interestingly, the Samsung store didn't have the NX1, the flagship: "it's too expensive for their market", was the shop assistant's reply.
Since Xmas 2014 I have a Sony A5100 as my main camera, which is an excellent HD camera for the price, but since the NX500 is available for about the same price, the NX500 might be (nearly) as great camera. The A5100 has extremely snappy,
accurate and quick auto focus in AF-C, which is especially important in movie mode for my solo shooter jobs). The NX500's AF-C was not as quick as the A5100's: when I touched the screen on the A5100 (with PZ1650) it locked immediately, at the same time, same place in the dimly lit Samsung showroom, the NX500 was always a tad bit hesitant to focus. My quick conclusion was that A5100 AF-C in low light is a tad bit better than NX500.
Touch to magnify while recording in manual focus mode. In your review you mentioned that MF support is not really great on the NX500. What I was looking for in the shop when experimenting with the NX500 was touch to magnify to confirm focus in MF mode. Somehow this feature is missing or I wasn't able to find/enable it: on the A5100 when I switch to MF, touch-to-magnify as well as focus peaking are automatically enabled.
I have an Atomos Ninja2 to use the A5100 for long-taking videos (events, conferences, concerts, interviews). Can you test if your NX500 can output
clean 1080p HDMI in liveview mode or while recording? My Nikon V1, for example was crippled by Nikon in this regard. BTW, the Ninja2 has no touch-to-magnify feature either.
As for stills photography. I mostly skipped those parts of your review: I think
today's cameras are so great with still images (starting with Nikon V1 and up) that I cannot see any real diferences. I have Nikon V1, Sony A5100, I used Olympus PEN EP5 (with external EVF), Fujifilm X-A1, Sony A7 (that was a beast!) for months, and all were excellent for photos.
The real discriminating factors are
video and special features: high resolution tilting touch screen, high resolution fast EVF, accurate and fast focus peaking, Speed Boosters and adapters for high quality Canon (EOS and FD), Nikon, Olympus OM, Minolta MD and Leica lenses. Kipon tilt-shift adapters for Nikon lenses, and so on and forth.
Investing into
expensive high quality Samsung lenses is another big dilemma. Canon EF, Sony E mount, Micro 4/3, Leica M mount (even Fujifilm X mount), are much more established than the Samsung mount, and I am a bit hesitant to go into the Samsung tunnel. Canon makes interchangeable lens cameras from APS-C, full-frame, cinema cameras all using the EF mount. Even Blackmagic makes cameras with EF mount. Metabones makes Speed Boosters for EF mount for nearly every mount (except Samsung). When I buy an EOS lens, it can be mounted on practically any cameras (except Nikon and Samsung). Sony makes interchangeable lens cameras from APS-C, full-frame, consumer and professional cinema cameras all using the E mount. If and when I buy a Sony or Zeiss E-mount lens, I can use it on a hell lot of cameras in this range. Samsung: they have only two decent cameras NX1 and NX500 both APS-C still image cameras, that's all. I see no system here, at least not now. I jumped out of the Fujifilm camp because it was really a very small market and limited support.
Just some additional thought to extend the scope of your review in case you wanted to continue your brilliant work.
BTW, the form factor of
Samsung NX30 was very clean, I loved the tilting huge EVF. If only Samsung made an NX30 mark 2 camera with all the new features from NX500. I am quite happy with the A5100, and when I upgrade, my next camera (Sony, Canon, Samsung) must be absolutely much better than the A5100 in that price range. I don't think Nikon will ever make a Nikon 1 model that is significantly better than the V1 I have for three years now.

April's Greetings
