The same range, but f/8 35mm equivalent aperture.

Lets look it other way - you don't have to pay extra 200$ if you don't need this feature / upgrade.

S5 II has failed even in vlogging af test, watch iPhonedo video - it lost his face for a good minute when he was filming himself in good daylight, smoothly riding onewheel.

A7S3 is 3 years old.

Try to shoot portrets of non-static people with fast primes - and then we will talk about "uselessness of fast and ACCURATE" PDAF in real life.

No, it's not. Check reviews from Potato, iPhonedo, CVP and other respected reviewers. it's not possible to make a perfect AF system in the first generation. It took Sony and Canon 2-3 iterations to...

I assume photographers would prefer other bodies to shoot full raw fast bursts )
Clearly S5 II aims at videographers / hybrid shooters with video first features in mind.

it's nowhere near as robust and reliable as Canon's or Sony's AF in the latest bodies, what kind of reviews have you watched?

Scratches, dust particles and other "imperfections" on the front element of the lens are highly visible when you have a bright source of light in frame or hittin the surface of said element. Off...

If you don't need good AF for your work - that's fine, you can use ef lenses on E-mount.

And you are wrong - one can adapt Sony lenses on Canon camera)

EF glass on Sony cameras have never worked "natively", especially with speedboosters.

Canon's business is broader the just photo/hybrid cameras.

Don't you know that on Sony E-mount third party lenses perform worse then native Sony E glass in some aspects?

It is a world wide CONSPIRACY of Canon ( Sony, Nikon) , nothing related to quality/...

Sony A7R4 have its AF and drive speed anywhere near R6 Mark2? Two totally different cameras.

Obviously Canon had in mind to make their EF glass legacy work flowlessly on R system, in my experience EF lenses perform even better on my R6 compared to 5D Mark3, and I have used 7 different ...

Every time i used third-party lenses on my EF DSLRs Canon I promised not to do this again, the problems with AF accurasy/calibration were really annoying.
You would think that with mirrorless RF...

They updated sensors, hotshoe and body ergonomics via firmware?

MILC man
if you shoot only lanscapes and other static scenes, thats fine. But to get an image in action you need exellent autofocus and drive speed. But if Mp is your only consern - Z5 is as good...

I have now visible blackout in my R6 viewfinder in H+ drive mode (electronic shutter shooting).
I want shutter sound options with firmware update for R6 Mark1

Z5 is an amateur camera compared to this "beast".
