​Doesn't make a difference for me as well, the strangest moments are when the camera is mostly still and starts going crazy with the shifting (as seen in one of the videos I've posted earlier on).

I mean, generally, technology nowadays is an uncontrollable beast. Even the forum, at times it just logs me out or doesn't allow me to post saying it's saving.

​Much better, thanks for the effort. Yeah, it's probably like some people said before: issue is not as present with the old firmware. Or even with some units. Oh boy, what a chaos.

But Brian, it's only $1.500! That's quite reasonable for a doorstop with AC wi-fi.

Can't see myself shooting in Auto modes. Hope the firmware comes one of these days, have 5 more on my return policy. After that it's finally a7s and the horrible ergonomics.

I believe it would be hard to see in that example, too shaky, too quick movements, too tele-ish and too low contrast.

Let's wrap this up. This is not bloom, it's the NX1 doing what it wants to do if it doesn't like the exposure. Would be OK for a cell phone, but in a camera with a fully manual video shooting mode I'd rather not have it. It doesn't do it under low exposure.

Sure, might be that not every camera has this issue (though I'd really like to have one that is supposed not to have the issue in my own hands), but apparently lots of units do. So, as has been stated before, this should be a top priority for the software guys, not 1000 new features (that might work as sensationally as the histogram).

Here's the comparison featuring a Nikon D800, a Blackmagic Cinema Camera and the NX1:

Settings of the NX1 definitely all manual, no guides, no auto anything, I spent 5 minutes making sure of that. Firmware 1.10, though. With the other cameras I did what's usually to be done: throw 'em into manual and roll.

Hope I'll manage to get the Vimeo in here, can't seem to get it to work intuitively. Sorry for the bad quality, only one HD upload per week.

To everyone who doesn't see the drifting: I envy you, I'd love not to see stuff as well, life probably would be bearable at last.

​Tried putting it back onto the camera and then removing the lens? Much easier that way.

Welcome back, Ivar.  Yeah, I don't see it fixing anything. Waiting for the 1.2 firmware update and if that doesn't do the trick, I'll return again and stop thinking about the NX1. Got the a7s yet?

Oh and btw, imho it's much more likely on wide shots with a lot of different details, most of the shots that don't show the issue are pretty high focal length.

Just tested it, no real change. It might not be in every shot, but every fourth or fifth is enough for me. Not into playing lottery with the camera. Auto Brightness and all auto stuff off, shot in manual:

@neosushi I see it in most of my shots, so to me it is unusable. Will have to check the new unit out in the open, though when my new Nikon adapter arrives (don't like the Sammy lenses, either).

What the deactivation of the Auto Brightness definitely fixes: the EVF doesn't show these exciting flashes any more when the exposure shifts.

It's a horrible issue still, for me the camera is unusable in video mode.

I have one and a half weeks to return the camera, so if the firmware update comes within that window and fixes the issue, I'm probably going to keep it. Otherwise, it will finally be the a7s. I'm still a bit skeptical though, sure Samsung are featuring a whole lot of stuff within such a short time, but I still have the feeling they might not fix anything but rather add features that sound nice marketing-wise. So probably 1–2 more updates and then nothing much will be happening. We'll see.

Holy cow, just read about the upcoming firmware update, that's serious stuff in so little time. Now I'm definitely waiting it out.

4th post in a row, yeah.

So, I have the replacement body. And, lo and behold, the issue persists, even though it isn't as pronounced (might be the Sammy lenses I got, though, last time I tried with Nikon lenses; switching O.I.S. on and off doesn't seem to make a difference, though). Ordered from a different dealer, so I suggest that a ) only the cameras in Germany or Europe or whatever are affected or b ) the people who don't see it are blind.

I was able to reproduce it with all different kinds of settings, I've updated the firmware and so on, no real changes. It's just that sometimes it's not that pronounced. BUT, I think I found a surefire way to confirm this on your camera. Every time the exposure shifts occur, if you're in a relatively dark setting (being in a relatively dark room and just having a monitor in front of you to pan to for the triggering of the effect helps), anywho; every time this occurs and if the EVF is active, you'll see a flash in it that definitely can't be missed. It's similar to this thing that occurs when the AF has locked on, it makes the screen very bright for a little moment (don't know if this is a setting, it would sure help with night photography which I wasn't able to pull of with a manual lens, because you see almost nothing in the dark). It would be really great if people tried this, so we can know if it's a general issue with this camera. Man, I sure love this thing, especially for shooting photos, but I need a video camera mainly. After all, this might have to do with the backlit sensor and not be fixable via firmware update, dunno.

Besides that I've noticed how warm the camera gets (no wonder with the monster CPU) and even starts so smell like asbestos.  I wonder if that's going to be an issue.

Well, will have to see. One of these days I'm heading off for the field to see if the footage is usable, after all it doesn't seem to be as bad as with the last unit. Might have to do with me using the Sammy lenses now, though.

Still, I'm under the impression that this is a stills camera that had the video mode added hastily. No wonder, too, Nikon and Canon haven't been doing it differently.

Or wait, it's the other way round, isn't it? It's gonna get cropped? Never had extenders, they probably do the same. Focusing would probably be influenced though, I guess. Just speculating, someone who actually knows should chime in.

EDIT: Crop it is, this is from Wikipedia about Extension Tubes:

The farther away the lens is, the closer the focus, the greater the magnification, and also the greater the loss of light (requiring a longer exposure time). 

​Heh, with that flange distance you wouldn't have to worry about focus issues, but rather about vignetting from hell. ; )

I've had it switched to Adobe RGB as well, will try sRGB when I get the new unit. So hope that it's going to work out, the 4k is so sweet for landscapes. I've ordered the kit version with the cheapo 16 50 3.5 lens and battery grip and the 16 50 2.0 separately. Definitely want at least one Sammy lens for the great AF, but I probably won't keep the expensive 16 50, I'd much rather have a Zeiss 21 Nikon, the Sammy distortion on the wide end is unacceptable anyway.

@DigitalEd love the detail on this little camera, that's probably why I'm giving it another try. That and it just feels so great in my hands, especially for photography.

I got the drift without overexposure. It might have to do with the wide angle, dunno.

Here goes:

Ah, darn it, I'm ordering another one. Liking this camera too much to give up already. Already sent it away today, but nvm.

I was thinking: perhaps it's also related to the Exposure/Focus lock and separation thingie (pp. 124 to 125 in the manual). Was confused when I read that first, but didn't mess with it, because I didn't have a native lens. Maybe you can try fiddling with the AEL-button? I do remember pushing it once. Although I did do a reset and everything when I was looking for a fix to the issue. Probably worth a try, though, I guess.

@nougat: Yup, this is exactly it. Tripod-still though, so there goes my assumption.

One more thing. Might be totally unrelated, but here goes:

I was just sitting on the John with my Samsung tablet and when I first got it I used to be annoyed by the strange flickering when there's a very contrasty image. So when I relog into a little game called Dungeon Keeper, there's this message that tells you to be patient with a black border and some brighter gray in the middle. The brightness flickering goes crazy during this time. Probably something like luminosity orbiting (as opposed to pixel orbiting) to protect the screen or whatever. Dunno, this might be the unique Samsung feat. 

Ah, I can finally post, my first post had to be authorized first. It's there now, but probably no one has read it.

I'm the guy who wrote to Andrew on Vimeo about the Frame Guide thingie. Thought it could be fixed by turning it off and using center weighted metering, but of course it couldn't. Strangely enough, I think once or twice, after playing around with all the settings, switching the camera on and off, the problem was gone, but well, I don't feel like doing that every time I need a usable video. What amazes me: that hardly anyone notices it. I could be faulty units, alright, but somehow I have the feeling that it's a general issue.

For instance: the impressive footage that Andrew brought (Lisbon) is mostly tripod-still and here I think the problem doesn't occur. I tried my best to make it reproducible and found the following method: I put a dark turquois background on my PC and had enough white areas for contrast, too, and then I tilted the camera up and down towards it. At one point it starts to shift the exposure and if at that point you stop the tilting and just move the camera ever so lightly, you get the flickering. So the camera probably keeps switching madly between two exposure values. Of course, if it's perfectly still, it wouldn't do that (at least that's my thinking). My impression revolving around that: the NX1 is mainly a stills camera and no video camera. I think they mostly worked on that part (and I really do love it as a stills camera, I find the image not really inferior to my D800 and it has the tiltable screen which makes shooting that much more interesting in terms of framing IMHO). Then they thought: oh look, 4K video is the new hype, let's do it, we have the processing power. See also in terms of the not so great video features. Poor histogram, missing flat profile. So, unless we get some hackers to make a Magic Lantern for the NX1 (for which it would be absolutely marvelous due to the fast CPU), I kind of doubt they will deliver in terms of video. And personally, I'd rather not wait for that, I can always come back later, IF this happens.

Over the last few weeks, I've tested first the GH4 of which I just didn't like the picture and the tiny, plasticky lenses, then the a7s which I thought had terrible ergonomics (and I just don't like Sony as a company with all their attitude towards an exclusive network and such), but a picture you could hardly break. I'm not a great professional in terms of lighting and such, it's just too much for me and with the Sony you can really shoot in every situation and get clean footage. I mean, it IS made specifically for video which the NX1 is not IMHO. So, I will send the Samsung back and rebuy the a7s. 4K is nice and everything, but I really prefer the dynamic range of the Sony (and I really do believe that the NX1 doesn't have impressive DR like many are saying; though it might be software related or even probably is) and the larger sensor for that shallow DoF. I also think that 4K introduces a plethora of problems into the footage once things start moving and that the technology just isn't there, yet. And most cameras probably don't even have the processing power to handle it properly. Which the NX1 would have, but I doubt it will be happening. With the next model possibly, but even with that I'm not too optimistic.

Just my couple of cents.

Ah, funny, finally found this thread. Glad, I'm not the only one with that issue. I'm said above Vimeo user.

So, I'll have to check out my findings in a few hours outside under daylight conditions. But testing inside I was under the impression that it had to do both with the Frame Guide and the metering mode. I seemed to get the best results with Frame Guide disabled and Center Weighted Metering. Choosing Spot Metering you can reproduce the issue best.

It's probably fixable through a firmware update, but I found another thread started by an NX300 user who had a strange issue with footage pulsating, losing sharpness at times. Samsung answered him that it was a feature and wasn't going to be fixed. This doesn't exactly comfort me. http://***URL removed***/forums/thread/3651399

This would really be a deal breaker for me. I like the NX1, it has so good ergonomics compared to the A7S, but with the A7S you can hardly produce bad footage (grading is another thing, of course). So if this issue persists, I'm probably returning the NX1 as long as I can and get the Sony back.
