    the isco ultrastar changes from 1.8X (1.5m) to 2.0m (infinity).
    I'll have to check with my elmo I and Singer/Sankor 16D if you wanna know for these

    Thanks a lot, I'm interested in those others too. How do you manage the different squeeze?

  2. "there was a guy who managed to make the Samsung communicate with Canon lenses with a conversion board."

    I think it's the same guy who made the Rocky Mountains Movie Converter. Looking at his site and videos it seems he can control both EF and NX lenses via Arduino. To me it seems he could be very close in making an active adapter if he has time and motivation.

  3. To my understanding (reading posts by kinoseed, ottok, vasile) I don't think that's possible.

    I-Zoom is a digital zoom that's available on some lenses, but it seems to work for JPEG for at least the lense I tried that doesn't support it. I now found out that it isn't supposed to work on video so I don't think it will be of any use. On JPEGs it goes from 1x to 2x.

  4. The burst setting seems to be for a different mode that's not on the left dial.

    [root@drime5 ~]# st cap capdtm setusr 9 0x90005
    UserData is set
    [root@drime5 ~]# st cap capdtm getusr 9
    UserData is DRIVE_BURST (0x90005)

    [root@drime5 ~]# st cap capdtm setusr 10 0xa0000
    UserData is set
    [root@drime5 ~]# st cap capdtm getusr 10        
    UserData is BURSTRATE_RATE30FPS (0xa0000)

     

    It's possible to set the Drive to Burst (Conti High is the 15fps mode) but when takin a photo the camera always wants to use the one selected from the dial. So whatever mode is put (even the ones on the dial) it uses the one on the dial.

  5. I was playing around with settings on NX1:

    I noticed I could set colorspace to Galaxy:

    [root@drime5 ~]# st cap capdtm setusr 48 3145730
    UserData is set
    [root@drime5 ~]# st cap capdtm getusr 48        
    UserData is COLORSPACE_GALAXY (0x300002)

    Whatever that is, the other ones were SRGB and AdobeRGB

    -----------------------

    I could use the iZoom feature:

    [root@drime5 ~]# st cap capdtm getusr 67
    UserData is IZOOM_X1 (0x430000)

    There were multiple zoom factors, it zooms on the LCD screen but the photos don't show it and it didn't work with video, maybe with some settings it could work.

    ------------------------

    I could set the burst rate to 30fps.

    [root@drime5 ~]# st cap capdtm setusr 10 655360
    UserData is set
    [root@drime5 ~]# st cap capdtm getusr 10       
    UserData is BURSTRATE_RATE30FPS (0xa0000)

    It shoots with burst but I don't think the camera did 30fps, sounded like 15fps.

    The D35 is more of a dream camera for me. Nothing like it currently exists. I actually made a list a while ago and posted on our user group that Joe was actually on board with had the funding been there to pursue it. It'd basically be an EMCCD version of our sensor, but double the dimensions and resolution horizontally and increase the dimension vertically enough to achieve 16:9.

    How does one actually go and make a digital camera? Are they build around evaluation boards with custom software, controllers etc?

  7. Here's what I tried. It changes the iso from 100 to 800 after one sec. Correct value should be the 1/framerate, I think. But even with 1 sec it crashes when recording video.

    #!/bin/bash
    while true
    do
        /usr/bin/st cap capdtm setusr 5 0x50001
        sleep 1
        /usr/bin/st cap capdtm setusr 5 0x5000a
        sleep 1
    done

  8. I tried to use a HDR script that switches iso. I only tried to change it 1 times per second and still it stops/crashes the recording very quickly. I was planning to try switching with a gap of 0.04 but didn't since the slow one crashed immediately.

    I measured how much an ISO change usually takes and it linux tool time gave a sys reading of 0.02 sec to 0.06 sec. My skills aren't enough to diagnose why it crashed the recording.

  9. I use this script for downscaling to 1080p 10-bit. It was done by karl from Personal View:

      It works with 0-255.
