When will Sigma and/or Tamron produce RF lenses?

Just like the title says -- when do you think? In the comments, please say which lenses you think they may put out, the order they may come, and/or what lenses you'd like to see from them.

Based on the success they have had in Sony mirrorless, I’m guessing they jump in soon. Especially because they can jump in on the ground floor when everyone is buying lenses and there isn’t much available. Plus, it’s pretty easy to undercut Canons prices at this point. I’m sure Sigma would get a lot of buyers for a mirrorless 85mm f1.4 that was super sharp and $1000.

Except they ask for more than that for their EF version.

Tamron would get tons of buyers for an RF version of their very successful 28-75 lens as well (although lack of ibis on canon is a bit of a buzzkill on that one).

If Tamron were to improve the optics of their trio of f/1.8 primes (35 / 1.8 VC, 45 / 1.8 VC, and 85 / 1.8 VC), I think they'd have a few smash hits. Would also be interesting if they were able to make an RF version of the 35-150 / 2.8-4 VC that was a constant f/2.8.

what is wrong with the optics of my $399 tamy 45 f1.8 VC?

the issues with the tamy 45 was focus with dslr's.  my 6d only worked in LV.  my RP works fine with the lens if I turn off the in camera lens corrections - otherwise I get a weird halo

to be honest - forget these 3rd party lenses

Canon needs to give us the RF lenses we want - the control ring, colors, and nano focus and 5 stop IS are astounding on my $899 RF 24-105 L.  And the eye focus is incredible.
