    • Canon XC10 versus Sony RX10 III. The Canon is underrated!
      Thanks a lot. This is extremely helpful... And just because I post a lot here, just means I have too much time on my hands. Ha. Actually, I am here to learn and get better, so I appreciate the detailed response. Thanks again... I love this little camera.   
    • A7s Sensor Size?
      Thanks in advance if anybody can help me track down the following information.  I need to know the exact dimensions of the 16x9 video frame used by the Sony A7s-II in both 4k and 2k video modes.  All that I'm confident about are the following: 1) full still sensor size measures 35.8mm x 23.9mm 2) full sensor resolution in still mode is 4240 x 2832. 3) 1 and 2 together imply a pixel dimension of approximately 8.44 microns square 4) 4k video resolution is 3840 x 2160. SO:  does this mean that the rectangle of sensor area used during 4k recording is 32.41mm x 18.23mm?  Similarly, what would be the as-used sensor dimension when shooting 4k in "full-frame" mode?  
    • Canon XC10 versus Sony RX10 III. The Canon is underrated!
      For me, down rezed 4k always turns out better 1080p than just shooting straight 1080p. But the 1080p is beautiful as a Ding an sich. Mostly, I just use it for slo-mo.  Regarding C-log, there's some debate about the exposure issue, I shot C-log over exposing with iffy results, but Jem Schofield recommends shooting C-log with 18% grey at about 31 IRE, and white at 62 IRE. If you don't have a wave form to help you expose 18% grey, I'd recommend putting your Zebra at 70% and not letting your highlights in C-log go over that. You'll find your lowest exposure setting in Log will then be between 10 or 15% IRE. Too bad the XC10 doesn't at least have a histogram...waveform would be better. Jem Schofield discusses log exposure and reading a wave form in one of the video tutorial he does on the Canon C100 cinema camera. you can find it on youtube pretty easily. When I expose that way I always get better results so far. If you have a Ninja II, or some external monitor you can get a good idea of how to expose using a gray card by checking the monitor's waveform. C-log exposed correctly should show the exposed gray card at just over 30 IRE when you fill the cameras image with the gray card shot under the light you're going to be shooting in. If you get the gray card exposed  correctly and then use a white card you'll see the white automatically shows exposure at just over 60 IRE. I find the XC10 censor just a bit bright. So when I shoot in TV mode I adjust the exposure compensation down about 1/2. I often grade C-log by hand with FCPX and Color finale--and get results that makes me happy with minimal angst. I'm sure others here with more experience will have more to say about exposing LOG. A wave form or histogram will give you some sense of what proper exposure that works for you is, and then you'll be off to the races. Hope this is helpful. PS: I just noted you're a regular here--so sorry for going over all kinds of stuff you, no doubt, know better than I. But it might just help someone else with the same questions but not the same level of skill.
    • Canon XC10 versus Sony RX10 III. The Canon is underrated!
      I think one thing that is significant but has not been discussed at all is the issue of stealth. Most people see you shooting with the XC10, with its tiny form factor, they just think you're doing a few snap shots.  They have no idea you're shooting high quality, robust 4k. Pick up a camcorder like the X70 and all of a sudden that's an attention getter and can cause problems in certain instanced in public.  No one ever bothers me with the XC10...
    • Petition for Samsung NX1 hack
      Vaga, ihkim posted about the nx protocol, and the canon ef one is well known. What should be done is a "conversion" chip, able to perform in real time.   You can read from here on: https://www.dpreview.com/forums/post/57372604   and here, with google translation, if needed: http://www.mydiyworld.net/
