Confirmed - 6K anamorphic will be released in a firmware update about 6 months after the camera is released.
I spoke with a Panasonic rep at CES and was told that the GH5 will ship without V-Log and it will still be a $100 extra - so factor that into the price if you are counting on using VLOG. When I asked why it is not included I was told "because it is essentially a consumer camera" and they didn't want to field a million questions from amateurs who were not able to work with log footage. I think that is lame.
If you go for the BMPCC I would suggest the BMPCC specific Speedbooster because the .58 version gives you a wider field of view than the .72 version and also allows more light through (1 and 3/4 stops I believe). The normal crop on the camera is 2.88x so with the .58 BMPCC Speedbooster you are looking at a crop of 1.6704x. I have the Nikon version and it works great. If you are serious about color grading, the Pocket Camera can deliver some awesome images, it just takes a bit longer in post. If you are already invested in Canon glass you should consider the EF version....the only benefit there in my mind is the ability to activate IS. For handheld work I simply use native M43 glass which is sharp and has decent IS. Another thing you need to know before buying the BMPCC is the problem it has with IR pollution - this has screwed me over far more times than the occasional moire. If you are using ND filters, outside in bright light, you will notice that the shadows are tinged with an ugly red which is nearly impossible to color correct. There are several solutions including filters that fit on the end of your lenses or IR cut filters which go directly over the sensor. The IR cut filters are not cheap, but I would seriously consider getting one if you plan to shoot a lot in bright, natural light. I also agree that you might want to hang onto the A7s if you can afford to do so, but I think it is worth giving the BMPCC a try. When everything is set just right the images you can produce with teh BMPCC are spectacular. One last thing.....you cannot set a custom white balance by shooting a white card with the pocket camera. This is, in my opinion, the biggest shortcoming of the Pocket Camera. Good luck with your decision, I hope this info is helpful.
It may cost you a hundred dollars or so more than your desired budget of $650, but as the owner of two BMPCC's and a case full of lenses I can tell you which one I use the most and get consistently great results with is the Panasonic 12-35 f2.8. You can find a grey market or used one for around $800 and it is totally worth it! The lens is contrasty and sharp and just fast enough to be usable indoors. The image stabilization is kick ass allowing you to use the lens hand-held and the range is amazing on the BMPCC it has the full frame FOV equivalency of 35mm - 101mm.
"equipped with a 72mm filter threat" - I am thinking this was meant to be 'thread' although I do find lenses that are larger than 70mm at the front glass a bit intimidating :)
I am currently shooting on 2 BMPCCs and a GH4 and am seriously interested in purchasing a monitor with professional scopes (RGB parade and a waveform). I want a bright screen that I can use with my gimbal and alsowhen I am locked down shooting interviews and B-Roll. The ability to load custom luts and also puncing in while recording in order to nail focus and color are important to me. I realize that if I am going to spend upward of $1,000 on a professional monitor it may as well be a 4k recorder as well to ensure future value. I think my next camera may be a Sony and at the moment I am leaning toward picking up a used FS700 instead of the FS5, A7rii or A7sii. I would like to invest in either the Shogun Inferno or the Odyssey 7Q+ to learn the ins and outs of the recorder/monitor while using it with my current cameras. Sometime in the next 18 months I will be ready to purchase a new camera and Sony will either have released a new camera that meets all of my desires or the price on the FS700 will have continued to drop making it a logical choice. From my next camera I want to be able to output in 10 bit, I would like to be able to shoot in 4K at 60 fps at times and would love to have the ability to shoot high quality 1080p at 240 fps. I like that the Convergent Designs unit can be upgraded to record raw from a variety of cameras that I may rent in the future and I also like the fact that it can be upgraded into a functional switcher.... However, the software interface on the Atomos is much slicker and the price is ultimately lower because they are not charging extra for the raw recording abilities. What do you folks think. Should I go for the Atomos Shogun Inferno or the 7Q+. Is the ability to shoot in raw at high frame rates on the FS7/FS700 worth the extra $1K or so that CD is charging for their unit with the raw upgrade? What about reliability? I have heard some seriously mixed reviews about the QC of the 7Q+. I appreciate any info from those of you who have experience with either of these two recorders.
