A9 vs R6, a different speed test

2020, the year of the Covid and after a while the year of the first mature mirrorless full-frame made by Canon.
Now we have R6 and R5 and Sony with his A9/A7 classes is not anymore alone in the mirrorless full-frame high performances market (sorry Panasonic, sorry Nikon, sorry Leica).
We have read tons of reviews, previews, post reviews, videos, comments; we know the great IQ, the superb body quality, the excellent speed, and the accuracy of the AF with RF lenses.
Indeed this is more than known so why another review/test? even for A9 vs r6?
Because looking around on the reviews we can’t find a single one who compares the “adapted lenses” and the speed of them in difficult and repeatable conditions, most of the reviews are for the average guy.
Today, with the help of two of my photographer friends I had a chance to test the fastest mirrorless of the market, the Alpha A9 by Sony against the new contender, the “cheap” Canon r6; and to make the competition fair, I avoided any native OEM lens, so no FE by Sony on A9, and no RF lens on R6 but the oldest EF lens I still keep in my equipment: the Canon 200 2.8 Lii!
Old and a good reference for anyone looking where to adapt his old (and not too old too) EF white lens; sometimes this equipment is very expensive and after many years of work is great to have a never body with the super-accurate ML AF to use their optical performance. 
The adapters were the Sigma MC11 for Sony and the RF to EF lens adapter for Canon.

The test?
A bike doing “stuff” and running to me from almost 10/12 meters; on green the good pictures, on red where Af failed.

A9 1

A9 2


R6 1


R6 2

What to add?

It’s easy to see the superior performance of the Af on the Canon, besides the poor performance of the lens on the minimum focus distance (there is the limiter from 3.5 meters for the maximum speed), I would say a normal behavior, the feeling of the accuracy even during the sequence is unbelievable!
I shot with the electronic shutter and the fastest setting with both bodies.
Yes, the A9 with his stacked is out of this world, you see the camera working just because shot counter… on the r6 there is still a little blackout during the fast sequences, nothing too annoying btw.
So, for Canon EF lenses is the R6 the new king of the hill under the 30mpx world?
Yeeeees but with a small flaw.

The shutter delay.

This sequence has been shot almost a second BEFORE the jump, but this is what I got.
I repeated to be sure and yes, with E-shutter there is a big delay between the pushed button and the first frame.
This is something you can’t find on Sony even with adapted lenses.

Of course, with native OEM lenses, both cameras are speed monsters, very accurate on the Af side and I would say with a small edge from A9 cause the stacked sensor and the fastest readout from his sensor with e-shutter.

PS.
I had the chance to test the Af quality of the A9 using a FE not native lens from Samyang, the 85 1.4 at 1.4!
Hard test… and this is the first and only try I did:


I am surprised to see a better accuracy from Samyang than Sigma (I had the 104 1.4… slower and less performing on the Af side) but we are far away from the monster performances you can have from the 135 1.8 GM or even the slower 85 1.4 GM .
