The XPS 9570 still suffers from CPU and GPU throttling when run hard (like my 9560) but as it has Thunderbolt it can use an external GPU. These slim laptops are just not designed to deal with the thermal stress of sustained high CPU and GPU rates but if you can offload this work to an external box it may solve it. I have a 4 disk RAID0 on my 9560 via Thunderbolt which gives me 500 mbps data rates but the Thunderbolt chip side of the laptop gets very hot. If you have a big raid storage box and eGPU + laptop you have to ask yourself why are you not using a small desktop ( micro ATX form factor) PC and a Screen......

Yes but you will be throwing away image data in the process and there is no need when you have proxy workflows available.

Basically I'd say you need a totally new PC if you are editing a feature on a 4k highly compressed codec as you will need a lot of CPU power as well as GPU + fast storage.

The standard XP’s 9570 is a better spec - do you really need the 2 in1 feature. Laptops are pretty poor choices for 4K video editing as they just don’t have the cooling capacity so for real-time playback and rendering and they will shudder to a stuttering mess very quickly. Good for reviewing footage but for editing I’d stick to a good desktop machine.

A laptop is never going to be the ideal choice for video editing. You pay a premium for portability but lose out on screen size, CPU & graphics power. It's much better value to buy a desktop with a decent large monitor plus you get a more powerful upgradeable system.

The OP is doing multiple exposures so the images have to be in perfect registration so IS has to be off for this use. Other scenarios may well differ. When I mount my Canon IS lenses on my GH5 I get the choice of using the lens IS or body IS and it's clear that the body IS is doing a much better job for video than the lens IS. I don't shoot stills with my GH5 so it may be different in that situation. Most tripods suffer from 'jitters' when you are using a long lens and there is any breeze around so it's often advantageous to keep IS on in these situations for a locked off shot.The GH5's IS system is pretty amazing esp the dual IS and even more especially the 'IS lock' setting which has in a lot of situations made my tripod redundant.

or put another way - would you buy a C200 instead of the BMPCC 4k if it was 1/2 the price.........

4k is not even a capture tech - it's just a sampling rate. '4k' can be HD 8bit 4.2.0 in a 25mbps badly compressed codec up sampled or it can be derived from 8k RAW 4.4.4 16bit. It's not a standard of image quality at all unless you start referencing broadcast standards where resolution, chroma sub sampling, bit depth and data rate are objectified and testable criteria. Thus a client who requests '4k' in image terms is like a client who requests 'hi-fi' sound in audio terms.......

F2.8 zoom lenses with speedbooster become F2 lenses which are F4 equivalence on M43. This is plenty of subject background separation plus enough DOF for focus accuracy. A speedbooster on M43 is not far off S35 or the classic cinema 35mm frame size so if you can't get 'cinematic' footage with this you should be looking elsewhere for it. If peoples idea of cinematic derives from film shot on 60/70mm film then yes the M43 system may not be a good starting point....

In that case I'd use fixed ND filter + a VND and as long as they are all good quality multicoated glass you shouldn't see any image degradation.

That won't work as the  adaptor body is not the same thickness as the non speedbooster adapter. With speedboosters the adjustment if you are short of infinity is to wind the optical group towards the sensor.

We are living in a post-truth / alternative facts world now so while it may be factually provable by optical calculations and various laws of physics that the only thing that determines perspective is the subject to object distance it is also equally valid to say a 'wide angle' lens has a certain 'look' that is independent of the format and personal belief in this or any other similar notion is just as valid. Indeed there is evidence to be had that there is a vast conspiracy involving all the camera manufacturers and scientists in the world to promote the idea of 'perspective' to sell more cameras and lenses. For many years now we have all been ready to accept the scientists opinion that the world is round but thanks to a growing number of brave and pioneering individuals and groups around the world the truth is finally emerging that the world is infact flat. Only just recently was I able to satisfy myself that this was indeed the case when I took my old school ruler down to the sea and held it up to the horizon - no so-called expert can argue with that can they!

If you post a purely technical test then it's open to comment - I'm not criticising the person. If anyone 'loves'  their camera and is hurt by comments on it's technical abilities then maybe they need the kind of help that I or anyone else on this forum can't give......

No need to be nasty..........
