@brianl where did you find brand new Nikon D7100 at 700$ am curious.

• the NX 1 records 4K downscaled from 7K in super 35mm sensor size internally. For me this is the most attracting feature! 1500$ is cheep if the camera performs in 4K as expected. For now, I'm impressed with the jpeg image quality.

3200 on the nx1 is worse than 6400 on the nx1...so don't use 3200 on the nx1

The results are definitely intriguing. You have to consider the well size of the NX1. The results are quite good considering this shouldn't be its strong point. 28MP APS-C vs 24MP FF of the D750

I would like to see a lot more. NX1 tests have been strangely lacking. Considering you can order the thing I would think you would see some more info about it. I'm really most interested in the AF tracking of the camera. They say its the fastest af, but thats in a vary controlled situation. Traditionally mirrorless cams fall behind the DSLRs with the dedicated af module. At 15fps af tracking needs to be right on or you'll end up with a lot of misses and trash on your card. Comparatively the D750's af is great, its only 6.5fps but the video looks great too.

@DrDave there is a difference, NX 1 ISO 6400 looks like D7100 ISO 3200. One ISO stop better performance than the best APSC out there, must mean something, even in jpeg mode.

@DrDave what did you expect, D750 has one of the best FF sensor out there. Actually to my eyes NX 1 ISO 6400 looks a little bit better than D750 ISO 12800. This is definitely better than any APSC camera to date. I'm impressed.

One thing thought, I don't know why he used Adobe RGB color profile instead of sRGB like the rest of the cameras he tested, the tonal curve and colors are strange on most monitors this way.

List of Video Specs from Samsungs site:

• Image Size: 3840x2160 (30fps Only), 4096x2160 (24fps Only), 1920x1080, 1280x720, 640x480
• Frame Rate: 60fps, 30fps, 24fps NTSC / 50fps, 25fps, 24fps PAL
• Multi-Motion Recording: x0.25(1280 30/25p, 720 30/25p, 480 30/25p only), x0.5(1280 60/50/30/25p, 720 60/50/30/25p, 480 60/50/30/25p only), x5, x10, x20
• Quality: High Quality, Normal, Pro(3840/4096 only)

I don't understand the Multi-motion setting. Is it a variable frame rate setting, timelapse etc?

Presumably the quality is for different bit rates, all 4:2:0.

Custom compression?

I was referring to a 10% speed of 240 fps, like the 96 fps conformed to 24 fps in GH4.

Such thing still write as 240fps footage, just different key frame intervals and fps setting is used for playback.

@Eno how did you come up with HD240fps fitting in the 4k24p stream? Unless I'm missing something, as I'm not an expert here, the UHD (3840x2160) 30p has a higher data rate then 4k.

(UHD8.3mp/frame)*(30frames/sec)=(249mp/sec)

So the same data rate at 2mp/frame would allow for about 125fps.

I have no idea how the bitrate or h.265codec factors into this. But it would seem that a simple calculation like that can tell you what the encoder might be capable of. I don't know why they wouldn't have used a stronger one to allow for the high fps the sensor is capable of. Would it be that much more expensive? Does all the hardware have to be improved by an equal amount to make it possible?

I would say that those are irrelevant questions, as we get what they give us, but we don't nearly have the whole picture yet. Without tests and the final firmware.

Or maybe the engineers were getting the raw 28mp 240fps output from the sensor, without encoding. The hardware certainly can't encode this amount of data, and to store this stream as RAW would be totally impractical.

@Vitaliy_Kiselev 24 fps in 7K with h.265 wold be nice, h.265 codec supports in theory up to 8K and 60ps.

Even 4K is enough if they don't screw up the JPEG engine of the camera! :))

From the article @Vitaliy_Kiselev posted:

DE: So, when it's clocking it off at 240 frames per second, is it not sampling all of the pixels? It reads the entire frame, but not every single pixel? Or does it read every single pixel? [I'm having a hard time believing the latter.]

JK: Every single pixel.

DE: Wow, so 28 megapixels, at 240 times a second. [This is mind-boggling faster than anything else we've ever seen before, outside very specialized and insanely expensive scientific systems.]

JK: Yeah, software can't do that; this sort of thing is why we implemented such powerful hardware.

WOW!

This camera would be interesting to hack for enabling 7K recording and 240fps in HDMI output :).
