So I took advantage of the crazy deal here in Switzerland and apparently I got one of the last ones.

I have a question regarding 4k vs uhd.

From what I gathered online 4k apparently has a little less rolling shutter than uhd, but uhd is supposed to be a little sharper.

I tested both and I can't tell the difference in image quality.

They both have the same horizontal FOV, uhd having more room in the height. Uhd also has more height framing adjustments possibilities if you crop to 2.35:1.

Since there is no horizontal FOV gain with the 4k mode,  I don't see the advantage of shooting 4k over uhd? I could not tell visually that the image was higher res as well.

appreciate some input on this thanks

Hey guys, they fucked up, 4K is totally cropped, like m43 or something like that.

Marco.

1) I was clearly describing the 1080p in my post. That is the question I was answering.

2) In your shots, especially the cute baby, there is a huge amount of compression evident in the shadows. Especially the skin tone on the arm and on the right side of his face in shadow. For web at 720p it will look fine, but not even close to good in 4K.

I love my NX1, but lowlight is a significant weakness.

I don't want to sound negative, but what you are looking for will be pretty bad on any camera system, it's only a question of "good enough". These super-zooms are made for convenience, not for absolute image quality. If you shoot for web galleries or comparable use, all of them are sufficient and so will be the samsung 18-200 I would think.

The 16-235 is considered broadcast safe. It should be used in camera only when one is not planning to grade the footage.

The reason is that it DOES change what is recorded, by reducing the discrete steps that the full range of intensities are recorded. When broadcasting the footage most of the times it is not important but during grading the footage will be more prone to banding.

There should also be a flag in the file that some programs use to display the footage correctly. This is a bug in premiere and it is easily fixed by applying an adjustment layer with the levels increased. But adobe should fix it. 

 Yes. Premiere (and most NLEs) work in 0-255 RGB mode. 

i always wondered the same thing. I mean...16-235 is a smaller discrete interval than 0-255. So, it's straightforward that you can map 0-255 exactly to 16-235, but is the opposite possible?

 

What am I missing?

This saves you having to apply the Fast Color Corrector in post but you can of course record in 0-255 and bring back the shadow detail and highlight roll off nicely with that

I've had this same problem, but only when the camera was shut off or went to sleep. I figured it was parking the internals of the lens in a safe position. Is your camera doing this without going to sleep or being turned off?

Imo nx1 could be much improved via a fw update implementing higher bitrates and better encoding algorithm. If I shoot a still at iso 6400 using raw, then apply slight nr and enhance sharpness a little bit in lightroom, then resize it to 8mp (4k like) I get a much, much better image compared to a frame grab from 4k video at iso 6400.

anybody tried a M42 to NX adapter, I got a bunch of excellent M42 optics but I tried it with a GH4 and was very disapointed? It felt like the glass was to far from the sensor and I'm afraid it could be the same with the NX1...
