    Bought Zhiyun weebill s image transmission module for 150E. In can be purchased and used separately from the gimbal. Works with any camera having HDMI out. Nice monitoring solution for BMPCC 4K. 
    For 150E + my Samsung Galaxy phone or an older Samsung Note 4 that don't use got very nice OLED monitor with great colors, 800-900 nits of luminance and touch screen interface. All major tools, like peaking, histograms, zebras, false color are available. Even more interestingly, it communicates with the camera and you can set all major parameter like white balance, ISO etc. from the touch screen. So it is a monitor but also a controller. A separate USB cable is used for the controlling functionality. Quite a nice alternative to much more expensive specialized monitors. And you can change easily the screen size too

    A guy told you.  Samsung T5 portable SSDs which are among the approved ones are 90$ for 500Gb and 137$ for 1Tb on Amazon. And that's cheap for me, cheaper even than SD cards per GB.
    https://www.amazon.com/Samsung-T5-Portable-SSD-MU-PA1T0B/dp/B073H552FJ/ref=sr_1_3?crid=1HC73MBGQQW2C&keywords=samsung+t5+portable+ssd&qid=1575587372&smid=ATVPDKIKX0DER&sprefix=samsung+t5%2Caps%2C252&sr=8-3
    And on approved media BMPCC 4K has no limitations
    By the way tried a Micron M2 SSD in an enclosure just because of the smaller dimensions. And BMPCC 4K didn't recognize the drive. But read other people were successful using non approved SSDs. 
    So it's up to you. I use Samsung T5 and SD cards. BMPCC 4K can record BRAW 5:1 on a SD card and that's good enough for 90% of what I shoot. For the rest there is Samsung T5 SSD.

    1. You can't use EOS EF-S (APS-C) Canon lenses on any speedbooster or Canon full frame camera. They have plastic part that protrudes deeper then normal full frame EOS EF lenses. Some people modify - cut the protruding part or simply pop up the plastic part in the back of the lens in order to mount them on full frame camera. I've done it on cheap EF-S 18-55mm f3.5-5.6 but won't do it on expensive EF-S 17-55mm f2.8.
    https://en.wikipedia.org/wiki/Canon_EF-S_lens_mount 
    Solution is to use third party lenses, like Sigma or Tamron, they have standard EF mount and fit without problem.
    2. Viltrox speedboosters are cheap but often problematic. That's my conclusion. Have exactly the same combination as The ghost of squig - Sigma 17-50mm f2.8 + Viltrox EF-M2 II and it doesn't work. Tried BMPCC 4K firmware 6.2 and 6.6 and Viltrox firmware 2.3 , 3.3. Neither stabilization nor aperture work in any combination of firmware. So maybe my Viltrox is defective because it can't even change aperture of any other Canon lens I have (24-105mm, 50mm, Tokina 11-16mm) except Canon EF 35mm f2 (old version). By the way there is new Viltrox firmaware 3.4 but can't test it now.
    Solution for me is unfortunately to buy the much more expensive Metabones speedbooster.
    Otherwise BMPCC 4K is great for me. It has it quirks, they are well known but there are ways to get around them. Like  and use the camera a lot.

    Have this lens. Image stabilization works very well. It's controlled by the camera and by default is ON. You can turn it off in the menu (Setup).  Am sure was mentioned before but IS on BMPCC 4K works only when you start recording if you are using the internal battery. Obviously this is made to preserve the battery which doesn't last long. If you use external battery IS works all the time before recording and during recording. 
    During firmware upgrade was also stuck at 70% but after some time camera said upgrade finished and it works OK. That was my second try. First try disconnected by accident the USB cable. But after re connection was able to start upgrade from scratch and finish it successfully. So in my understanding firmware upgrade is well thought out.
    But new firmware 6.6 broke (again) Viltrox speed booster functionality. Aperture and  IS don't work with Viltrox firmware version 2.3 neither with version 3.3.☹️

    Presets could be used to speed processing time. Don't shoot weddings but had similar discussion on a local forum. A pro photographer using Sony for weddings said that he uses presets for all images.  20-30 of the best photos he process individually. That's exactly what I would do too. He has clients in Switzerland and Germany and shoots with Sony exclusively. 
    If you like Canon colors out of the box and/or save time is post then of course use Canon.  
    Have both Canon and Sony cameras. 3 months ago got EOS M and it's my 2nd Canon camera RAW ML video is very good - Canon colors, setting white balance in post, etc.  But still have to process, color correct and grade each clip individually in order to get the best image out of it. In the process learned quite a lot how to shoot with this camera and how to process the footage. And it is like this with every other camera.  Recently did a small project with Sony A7 III.
    Search on youtube for EOS M RAW. There are plenty videos shot in RAW. Some are crap, some are OK and some stand out. Same camera, same color science (RAW) but quite different results. Zeek really makes this camera shine.
    But yes in general getting good colors with Sony is more challenging and requires some research tests and fiddling with the settings, profiles, etc. A7S uses a different sensor and because of it or because of different CS is the worst when shooting 8bit 4:2:0 x264 video. With RAW format for photo don't have a problem.

    It depends what same converter exactly  means. Same converter program or same program + same settings.
    Same converter + different adjustment values in converter + different camera = same colors
    Have done tests in photo with different cameras and there is no problem to get the same colors for the same scene  and lighting with different cameras and even different lenses.
    For me it boils down to what frontfocus said:
    And as how we see color is subjective, better starting point is also subjective. So there are some camera+converter combinations that we like more than the others and get us the colors we want and like much easier.

    It depends what kind of AF. Tracking AF in video is not working. At least when in ML RAW modes. It's working in photo mode. But don't like it and don't use it.
    However single shot AF is working in both photo and video including ML RAW. Single shot like: you press the button, camera focuses and signals when focus is achieved. It's kind of slow but it works and focus is reliable. In my settings different buttons are assigned for focusing and exposure metering. 
    Here is how usually shoot no matter if AF or MF is used.  1. check/correct exposure settings 2. Frame 3. Focus 4.Start recording. It's a slow process but works reasonably well. This is not a camera for fast paced shooting. 
    Settings in video are as follows: AF method - FlexiZoneAF square / Focus mode - AF+MF

    Agree with you on the point that deleting a clip and moving the play head the same length ahead is annoying. This is something they should definitely think about and fix.
    But other than that, like the new cut page. Did some edits on the weekend  - a short 2 minute video composed from approximately 30-40 smaller clips. And a bigger one assembled from 150-200 clips. The two timelines approach, with whole thing on the top and detailed clips at the bottom really helps me cut faster. Guess it all depends on our editing habits. Was able to almost finish the two small projects (total length of 7 min) in one day. Usually it takes much longer and this is the most difficult part for me - choosing the clips, or parts of the clips, figuring out the way to arrange them, composing the whole video. Now this whole process was easier, faster and even fun. 
    Here is a good demonstration how new cut pages helps get this part done faster:
     
    Resolve is an incredible piece of software, especially considering the price.

    Also looking for gimbal able to carry cameras slightly bigger than mirroless - BMPCC 4K, Canon 5D Mark III. And so far Moza Air 2 seems to be the best choice with only 2 drawbacks - weight and size. Moza gives a weight of 1.6kg with batteries.  Brandon Li complains in his review about the weight. But in Feiyu AK2000 gimbal review he says weight is OK. According to the specs Feiyu AK2000 with batteries is 1.4-1.45kg. Don't think 150-200g will make such a perceivable difference. And in most other reviews Moza Air 2 is measured to be close to Ronin S.

    Fully agree with TheRenaissanceMan and you. We are on the same page here. How easy or difficult it is to get the color we want makes huge difference. My comments about RAW were mostly for photo. Tony's test is mostly for the photo side of hybrid cameras. Adding video in the bag is not correct, because:
      a. as you point out most DSLR mirrorless cameras  shoot 8bit 4:2:0 which is quite different and limited compared to RAW and even JPG. Getting the colors we want may be quite difficult and time consuming. 
     b. RAW video is not = to RAW photo. Most if not all cameras shoot  RAW video but in log format. Which means some kind of additional processing related to colors is applied in camera. It is not the RAW image as it comes from the sensor. And cameras from different companies have different log formats, even the sensor is the same. For example Panasonic GH5S and Blackmagic Pocket Cinema Camera 4K. Same sensor, different log formats.
    In both cases  there is some form of in camera color processing/manipulation. We still have the problem measuring those colors in RAW, we still have to go with the development process before any measurement is possible. But it would be correct to say there is in camera color science and is logical to expect that it will affect the end results. 
    Tony's argument that people will not notice and object slight variation in color and sometimes even big color shifts also is not correct for video. We still want to get the colors we want and even we ignore this we still have to color match different sequences under different lighting condition in one movie/clip.

    There are no colors yet in RAW. What to test then ? The color science of the developing programs or the skills of the person working with it ? For photography everybody is using RAW for serious work but yet argue about BETTER color science which affect only JPG and is different for different profiles and is subjective at the end. Better doesn't mean accurate. Better is very subjective. In this part he's right IMHO.  
    For video however it's different. For those mirroless / DSLR cameras we don't have the choice of using RAW video. We still can tweak the colors but are much more limited, white balance is backed in. Tweaking the colors the way we like them is not that easy in video as to take a RAW file and fix the white balance. Getting the colors close to the final edit straight off the camera for video may save tons of time and effort. So don't agree with him when he throws video in the argument but does only test photo.

    He mentions that color science apply to JPG photo and video. RAW allows you to change colors as you like when developing. Test was for JPG photos. He also says that there were indoor scenes and outdoor scenes, so in my understanding it's not only the photo he's showing in the video. There were several photos/scenes but he’s showing only one as an example. He says nothing about the creative style / picture profile used. So assume standard was used for all cameras.
    Dave Dugdale has a video comparing all Sony A7 III creative styles. With picture profiles off, standard creative style seems to be the best for skin tones in video.
    https://www.youtube.com/watch?v=q6VyspXsS5I
    Tested it in other scenes and scenarios. Surprisingly it works well and am quite pleased with the results in most of those scenes. Dynamic range is not the best but not all scenes need it. Use standard for video quite often. So  this is one more confirmation Sony colors in last generation cameras (A7 III, A7R III) seems to be accurate in Standard style.
