As many of you know, I'm a long time owner of an NX200 and a short time owner (3 months) of an NX30. I love both cameras and truly appreciate the image quality, small, lightweight size, and functionality/dollar that each camera offers.
I have been shooting long exposure, light painting photos with the NX30 for the past 3 weeks, or so. In general, there were no problems until about 2 nights ago. I noticed that "hot pixels" suddenly began to appear. These were in every exposure in exactly the same location on the frame. In addition to the hot pixels, there seemed to be more color speckling than usual in the black areas of each frame. All of this was coincidentally occurring when the camera stopped recognizing that I was using manual focusing (the magnified views and focus peaking stopped appearing). Finally, the on/off switch stopped working (I had to remove the battery to return the camera to normal operation).
The camera was sent to the service facility in New Jersey, Wednesday (2 days ago). I expect that they will get it, today. I was a bit miffed that, although the camera is fully under warranty, I had to pay for the UPS shipping for service. After I receive either some communication from the repair shop or the returned camera, I'll report back on the fix. I say this because I know that Nikon will not repair a camera under warranty if there are fewer than "x" amount of hot pixels. I'm not sure about Samsung's policy.
I'm wondering if anyone else has experienced similar issues or has had service work done on their NX30. I need to mention that the manual focus and on/off switch issue was intermittent and, once the battery was removed and replaced, cleared up. It did happen several times over a few days shooting.
One last thing, I used the Samsung service web page to report the incident. Their procedure for reporting is awful. A dropdown list approach that offers only a few choices (none of which were relevant for my issues) and an endless loop approach if you don't answer the irrelevant questions. I ended up writing a note to the service center and adding a photo of my issue to send with the camera since the "official" document transmitted to the service station my Samsung indicated that I was having a problem with my viewing screen. There really needs to be a better system in place.
