AF of Canon EF-lenses on SL3 (or SL2)?

I am interested in experiences of Caon-EF Telelenses on the SL3 (or SL2) with the mc21.

Would a EF100-400 or a EF400/4.0 do focus as fast as a Leica 100-400?

Too bad RF lenses can not be used on L-Mount bodies.

I very much doubt it.

I have The Canon 70-210 f4 L lens and it focuses much faster on a 7D than the SL and the 90-280 is also faster than the Canon lens on the SL. The 85 f1.2 L is just slow.

Same than it was with SL2. If only we could switch to afc with adapter, then SL3 would use phase autofocus but we cannot. Stuck with afs, it's contrast based focusing.

With S52 you can switch to afc and Canon lenses works very well. Sent email to Leica right away when I got SL3 but I quess this will never get "fixed". Tried with 135mm F2, 100-400, 300 2.8. 100-400 was the best of these. But it was the same with SL2..

So answer to your question, unusable. Shaky video:

to be fair, this lens is slow even on Canon bodies. that's a lot of glass to move around

Mikko, can you please reconfirm or correct: 

 

Canon or Sigma lenses with EF mount + Sigma MC-11 adapter EF > L

 

S1R (I use)

SAF: contrast detect AF

CAF: does not work at all

 

SL2

SAF: contrast detect AF

CAF: does not work at all

 

S5II

SAF: phase detect AF

CAF: phase detect AF (?)

 

SL3

SAF: phase detect AF

CAF: contrast detect AF (?)

 

S1RII

hopefully like S5II, not like SL3 😝

Almost right.

S5II

SAF: contrast AF (like with all lenses, same than with SL3)
CAF: phase AF (available because there is physical switch to enable caf).
 

SL3

SAF: contrast AF (same with all lenses, really sl2 level performance)
CAF: not available

[chrismuc]

thx Mikko

yes, strange that the SL3 does not offer CAF with EF-adapted lenses, while the S5II is able to

let's hope for a FW update
