I can add some sad word, i was journalist for 15 years, and too often i saw people that too fast fabricate scoop and bad words near famous people. The simple reality not sell more copies then fire's words.... ask yourself why book sell less then gossip magazine?

to be honest, i read this list, and i thought i founded somewhere "sponsored content"
1) like other brands, but with less knowledge how to develop a good mirrorless, previous canon did only two bad mirrorless.
2) more resolution per area sensor mean more diffraction, the reason be cause sonya7s2 and gh5s are 10mpx only
3) 4k no, only UHD when other like gh5 have 4k dci, the only advantage to sony is 4:2:2 recorded internally (we must check the bitrate and matrix compression to understand if are in a good quality or not), but ever 8 bit when gh5 from 2017 offer 10bit internally in long gop or intraframe...
4) high ftp? no, like my iphone... fps per resolution gh5/gh5s offert uhd60p, FHD 180fps...
5) canon color science... yes and no, only if you record with compression or good cs are wasted from bad compression.
6) good lenses and ef compatibility (by adapter)... like other brand... or you think the zeiss lenses for sony are not so good like canon... and with adapter i use on sony, panasonic ef lenses (i do from years, i had a bmd camera with ef mount, and i shoot photo with different brand, sony, panasonic etc, and i have adapter metabone to use EF lenses on all).
7) competitive price? i think no... also without buying external recorder to have 10bit 4:2:2 and canon color science ...
may be in future canon do better, i used many cameras from them and in the future i will do again, but... i'm not payed from any brand, i pay to have every camera and vendor must give me real reason to consider (not to buy) to use it against sony/panasonic/blackmagic

to be honest, many things, ok, but never monitor or cameras....
2000$ and more of camera on 10$ clamp? do you want to risk ?
i saw too much fallen camera from cheap tripods to see fallen cameras from cheap clamps

if you use filmic pro app you can remote it from another iphone and control what you are doing underwater.
if you want to be sure add a powerbank connected, a small ring of silicone, few hours and you are sure that no water or other go on precious smartphone (remember iphone is only drop water resistent not immergeable device like sony z series or samsung S6 and over series).

i had gh5, ursa minipro, my suggest is to go to pocket4k, forget gh5 and IBIS which is great with vintage and fixed focal lenses, but you have to deal with highly compressed h264. my notebook work fine with 4.6k of ursa mini pro, but not be able to reproduce fluently the 4k of gh5, many people miss that an highly compressed video h264 need more resource then a prores from a pro camera.
pro pocket vs gh5?
- better quality recording from raw to prores proxy which is ever better then compressed h264/h265 of gh5
- less crop, pocket4k have m4/3 mount but a 4/3 sensor, your vintage lenses have more room of shooting
- better low light sensor (like gh5s) with dual iso recorded in better quality that mean better noise reduction if you need
- recording on sd, cf or by usb 3.1 on external ssd, against only sd for gh5, and if you want to record 400mbits on gh5 the cost of sd is stellar against a prores 4:2:2 that you can record on simple 95mbits card on pocket4k.
- log more confortable then vlog of panasonic (i use resolve from 5 years, and i prefer so long bmd log then a vlog where you need to expose carefully and color correct carefully to have all dinamic range

gh5 vs pocket?
- ibis is confortable with vintage lenses, but often a good gimbal is better (i had both and during video i prefer gimbal then ibis, when i shoot photo obviously i thanks god that exist IBIS).
- dual recording card at same time
- articolated monitor (sometimes is very useful)
as i can i will buy pocket to complete my setup with dslr style camera, but real video / cinema camera like pocket 4k.

Adobe claim that is innovative, for them...
Resolve use this kind of curve from over 10 years, FCPX use them from last update, just to tell two of popular...
please don't blame me, i'm happy to use also in Lumetri combo curves, i like a lot from when i start to use it in Resolve years ago.
