Does anyone know if Canon officially claimed that they will not tolerate any 3rd party lenses for the RF mount? I mean...the R was released many years ago by now and we still have no native mount alternatives other than Canons own superexpensive glass. Or the cheapo kit-alternatives which seem to be mediocre at best.

You lost all credibility right there. None of the non-L primes is mediocre.

lenses with stepper motors have mediocre af, that's why tamron, nikon, sigma, etc. have all started using linear voice coil af motors.

no that's not correct.  You should try the RF 24-105 STM yes it's a stepper drive and guess what it's very fast, silent and dead on every time.  But Batman how did that happen?

WOW maybe you should try one some day, you have no idea what you are talking about 

where are the rf-mount lenses with linear voice coil af?

From the RF 24-240 up have Nano focus, its a form of voice coil but better, hmm.

It seems you did NO research at all before telling us all about Canon focus

sony has to compete with sigma and tamron, and e-mount owners benefit from that, greatly.

I have seen many amazing results from the 800 F11 (lots of YouTube videos from great wildlife photographers).

yes, canon has a solid history of decent cheap entry glass, but where do you go from there to get improved p.q. and real focus motors?

100-500+1.4x: $3200 = 700mm f/10, but you can't use the wide end

200-600+1.4x: $2550 = 840mm f/9

canon has never made a 600mm superzoom with af.

the new sigma 60-600 looks like a great lens, with voice coil af, but i don't see how it will compete with the 200-600, which is unmatched in any brand or mount, so why did sigma make it? can't use a 1.4x with it on e-mount, and nikon promised their own 200-600 three years ago, so they won't allow it on z-mount, unless perhaps it's re-popped under the nikon name.

in the end, the market will decide for itself which approach is best.

milc lenses with af:
e-mount: 179
mft: 78
x-mount: 71
L-mount: 61
z-mount: 47
rf-mount: 40
