Samsung NX1 getting log-like setting

I don't know where else to ask this ...

Just got the Samsung NX1 + Samsung 45mm f1.8 lens. When I have the f-stop set to, say, f14, what I'm seeing in the viewfinder doesn't look anything like what I know I should be seeing. Meaning, there's ***tons*** of shallow depth-of-field ... like what you'd see if the f-stop was set to f1.8.

So, I googled it, and discovered the "depth-of-field preview button." Sure enough, I press this button and it shows me what the image should look like at f14. The image also become a little brighter.

This is really odd to me. I don't recall having this discrepancy with my old Canon 5DMII, or Panasonic GH4??? When I looked in the viewfinder I thought it was always "what you see is what you get" with those cameras. Or maybe with those cameras I just always shot with my lenses wide open!? ;)

SLRs would always leave the lens open until the shutter is depressed. That way the image is bright enough for you to see before you shoot it. You would need to use the depth of field preview (if the camera had it) to preview the true DOF. But the image would get darker as a result. I'm not sure how DSLRs work in this regard for their video mode. Seems to me they would stop the aperture down the moment you put it into video mode, but maybe the NX1 works more like a traditional SLR and doesn't stop it down until the record button is pressed?

The fact that the evf gets brighter is to compensate for the light loss of the stopped down aperture.

Thanks. That helps. Yeah, as far as I can tell the NX1 is acting like an old SLR in this regard. It's really bugging me.

Also, it does not have a dedicated movie mode, similar to my old 5DMIII or GH4. It just has a dedicated movie record button. That's how you basically enter movie mode. This is odd to me, too.
 
^ That's how I've always shot. Set the camera on M, then hit record to get a video clip. My a7S has a movie mode but I still use M, there's no reason to go to a mode that's all just the same but makes the shutter button useless.
 
This is log on the a7s with some extra saturation, and it doesn't look like what most people expect log to look like. I haven't watched the NX1 samples, but maybe this is what's going on. I hope.
 
I own the A7s and BMPCC. The LOG on those cameras are much, much flatter than the one LOG example I've seen from the NX1 thus far.
 
This seems like a place for the Samsung management interview -

[h=3]A lot of the improvements in Firmware 1.2 are focused on video. How many of your customers are using the NX1 for shooting video?[/h] In Korea, the NX1 is being used by KBS [the Korean Broadcasting System] to shoot a drama series. They’ve replaced older, more expensive systems with the NX1, which is also much simpler. And we’ve added functions specifically designed for this use case scenario. For example, when shooting movies, you don’t always want very fast autofocus, sometimes you want a slow focus movement between two people in a scene. So we changed the AF speed options in firmware 1.2 to make it slower and smoother for video. In the USA, ‘Project Runway’ is also using the NX1 for handheld 4K video shooting.

I figure the Korean TV drama refereed to above is either sponsored or owned by Samsung, which is why they're shooting on NX1 but I would like to see what it looks like anyway.

Ok, now, go to the title of this thread or the press releases from Samsung and point to me where does it says the new gamma modes are LOG! There IS a difference between saying LOG and LOG-LIKE for those who understand it.

I went there. beautiful scenery. I lived in Madrid for a whole year in 2013 and loved it. All. The food, the art, the people. I can't wait to go back.

"...those who understand it."

No need to be condescending. I was basing my assumption off the Imaging Resource article where it says; "D Gamma is a preset logarithmic color setting designed to capture a wider tonal range for increased dynamic range.".

"Logarithmic color", in many filmmaking circles, means a flat image. Like Sony's S-Log. Like Canon's C-Log. Like Panasonic's V-Log. Like Blackmagic's FilmLog. Like Arri's Log-C.

So calm down.

In fact, perhaps Samsung should take a page from you and call it "Log Like" and it'd save a great many of us from being bewildered...

Samsung clearly calls them: C Gamma Mode for higher overall contrast and D Gamma Mode for wider dynamic range. Just like Cine V Gamma and Cine D Gamma with the GH4. It is in all the reports about the firmware upgrade. I myself did not called it "Log Like", Ed, who started the thread, gets the credit.

They are listening - try the new firmware in 2 weeks - then we can give them feedback and they will address or not address. Getting log is incredible. Don't get greedy. Also 10 bit is a hardware thing, not just firmware - which is just software.

Looking at the specs and reviews, the NX1 is nice hardware coupled (typically) with crappy firmware. Not only is Samsung listening but they're actively pursuing 3rd party development.

The NX1 has a lot of processing power which could make 14bit raw downsampled 2k recording to internal SD cards viable. Downsampling to 2k might be a way to get around the high 4k rolling shutter (it's much lower in 1080p mode). Another really interesting possibility would be HDR development and better low light performance.
