Yes, I have changed the levels in the NX1.


The GH4 and the LX100 also use sensor-crop for 4K video, but they have a smaller sensor with less pixels. It will be interesting to see if Samsung...

No sensor crop option (yet) for the NX1 - information from the whole sensor (28+ megapixels) is used by sampling to create the 8 megapixel UHD video. For the NX500 you only can use sensor-cropped UHD...

Could you please clarify what "noise" you are talking about? there is acoustic noise that you can hear and there is video noise that you can see. Which are you talking about? If it is acoustic noise,...

This is the problem in PD 13. You cannot change the levels in the NX500, and PD 13 is reading the levels wrong. I do not see how to change that in PD 13 either.


On the level of detail, it is...

The bokeh is purely a function of the lens and maybe the sensor. The lens and the sensor are the same as on the NX1 (if you use that lens, which Ken does). Thus the bokeh is what you would get from...

Yes, that is the crop factor (as opposed to 1.5 in non crop mode).

What's "sensor sound"? If you mean noise, then yes, there is more noise when the sensor is cropped - sampling from the whole...

Thanks. There is no problem with the resolution or color, but the minimum effective focal length (35mm-equivalent) of the 16-50mm lens is only about 45mm, which is hardly wide-angle for landscapes.

Why I prefer the Samsung NX500 to the NX1, Sometimes

The NX500 has two features that the NX1 does not have: 1. compactness, especially with the 16-50mm PZ lens, and 2. the crop factor in 4K. Both of these features makes the camera ideal for run and gun...

Here's another dimension: depth of field with respect to focus. If you use a big sensor camera (which none of you are doing), the dof is shallow. Now, for 2D, shallow dof actually gives the...

Unfortunately, PD 13 only gave me an interlaced render option among the higher bitrate options (1080 60i) in 3D mode. The other videos were all progressive (1080 30p); this was because a native sbs...

Sony HDR-TD10 versus Samsung NX500: 3D Comparison Video

No one is claiming that the semi-pocketable Samsung NX500 with its single-length 2D/3D lens can do what a 3D camcorder can do, but the Samsung NX500 gives a much nicer picture (in terms of color,...

We are both correct on cropping, but are talking about two different aspects of it: Shooting a 16x9 video cannot use all of the sensor if the sensor is 3:2 so there is some cropping, but the...

I agree with most of what you say, except I am confused by your conclusion that the 3D1 is a "superior" 3D camera to the NX500 (with 3D lens). It also has a limited range, but within that range it is...

No, this is one NX500 with a 3D lens. The NX500 + power zoom lens = $699. The 2D/3D lens = $379. You could sell the power zoom lens for, say, $100, so the net cost is <$1000. Of course, still more...

I am sorry, but I do not understand how in software you can get rid of sharpening or most any aliasing artifacts produced in the camera. Let's take one example - halos. They are in the clips. Pulling...
