GH5s or A7III? No way to decide

Big, big, big problem.

I need a video camera under 3K, body only, for 4k mechanic laboratory video.

No need auto focus or OIS.

I have canon EF lenses. To use in MFT I need Booster but, GH5S + Booster = A7III or less.

In low light both are more or less the same.

The unique difference it is 240fps vs 120fps and I prefer 240.

Relay it is so big difference, in the real world, between 240 and 120?

I have a6500 and 120fps are bad, like my English :(

I use external recorder atomos.

Any advice, please?

If its the 240 FPS aspect that you are most interested in and don't mind it not having the form factor of a hybrid, have you thought about a used Sony FS5 or even the FS700 with your Shogun Inferno as an alternative?

Both would fit into your budget and the FS700 would actually be a big saving.

I currently own a GH5s and love it for its reliability and low light capabilities. Plus pairing it with an Atomos Inferno means you can shoot 10bit 4k 60fps. But the A7III is a better hybrid camera so if you're also going to take pictures, that's the one to choose. Right now I would also like to own an A7III but with the P4K around, I think a GH5 / GH5s + P4k is a good set to have.

OIS? Or IBIS? Guessing you meant IBIS when talking about a camera comparison

Solid case then for a GH5S

False. You can use just a normal adapter. 
Or get a quality Viltrox EF-M2 for cheap if you want a focal reducer.

False. The Panasonic GH5S is clearly better.

If you already have a 4K Atomos recorder and looking for slow motion performance on a budget, then seriously consider the Sony FS700 on eBay (US$1.5K ish secondhand)

 

Also if you can stretch your budget, then the Sony FS5 is almost within reach:

For low light comparison, I would do a Google search "GH5s vs A7iii low light".

The ones I looked at mostly seem to have the FF camera on top (which is as it should be) though the GH5s does get a lot closer than it should.

If it was my choice, I would try both if possible and then pick myself on what works better for me.

The current used price of one is about £3200 but Sony have just cut the price of new ones so expect the price of the used ones to dip under your £3K budget.

With regard to the FS700, it might be 5 years old but I can't think of anything thats come along in that time that gives you the same performance options from a Super35 sensor and certainly not for anywhere near the £1200-1400 price that you can buy a used FS700 for.

In this instance, I'd take the 5 years as a positive as everyone moving on to new and shiny things has chipped away at the price of the FS700 in a disproportionate way compared to its actual performance.

There is an interesting retrospective of it here :

Wait a little while, or hit up your dealers to hurry them up and see if they'll be offering a similar deal from Sony too

Yes, but the FS700 is a unique camera for its level and time in how it is still managing to hold some relevance in 2018!
