Hybrid Camera for 70:30 Photo:Video use - around the £3,000 mark Sony Vs Lumix (or other suggestions)

Budget: £3,000 (body) £4,500 (body and lens')

Country: England

Condition: New preferable

Type of Camera: Mirrorless

Intended use: Hybrid Shooting mainly Product photography, with some portraiture. Video use will be less common but typically it is more product work again with high frame rate use

Photography; Product/portraiture, Flash photography, Occasionally Macro, and Travel

Video: Product Video, High frame rate/slow motion, cinematic sort of shots

What features do you absolutely need: Articulating Screen, Remote operation, Flash compatibility (Hot shoe), in camera audio with HDMI out. USB-C for ease. Remote operation/viewing with mobile

What features would be nice to have:

Switchable modes for video between high frame rate.

Portability: DSLR sized is fine - I have a old billingham Hadley large that I'm quite attached to, if I can fit it with a flash gun and 2 lenses (one on body) in it I will be happy

Cameras you're considering:

Sony A7V - heard it s good hybrid camera however not many reports of it Vs the 2 bellow the

Sony A7RV - high resolution is always great for product photography however I've heard rolling shutter could be a serious issue for high frame rates

Lumix S1ii - I've had Lumix G80 and S5 from new and quite like the operation and lenses and it feels more like home

Cameras you already have:

Have:

Lumix S5 with 24-105mm MACRO - the lenses and Menu are pretty nice however it's auto focus is infuriating for action shots in product photo and portraiture

Had:

Lumix G80 - loved the form factor and lens options with M4/3 but the resolution made product work difficult

Nikon 810 - way to big and heavy and no video features

Notes: If there is a decent lens suggestion I'm also all ears as I'm ideally looking for a decent one to replace my lumix 24-105mm which is a real multi use lens especially with the macro as it's amazing how many times you have to get fine details up close
