A used 17-40.
Can't you just use the already available EF teleconverters? The cameras come with an EF-RF adapter.How about an RF-EF 1.4X teleconverter. That would be ideal for people with some big EF glass already in hand. I mean, if you're going to fill that space, it might as well be with a teleconverter for use with long glass.
Not exactly true, but yeah, the RF lenses will rule them allThen I have no reason to buy a RF mount. I can just keep using my old 6D.
The 70-200 looks like it...Does the mount have advantages over EF for longer focal lengths? Would a 100-400 have a different optical formula?
I thought the main advantage is for short focal lengths, less than 50 mm normal. For example the 15-35/2.8 IS with a non-bulbous front element. Or standard zooms extending into the short focal lengths.

Of course, but why add length to an already lengthy package. I mean it's not a big deal, but why add a half inch or so of additional length to the lens with the adapter, and then another inch and a quarter for the 1.4X.Can't you just use the already available EF teleconverters?

I’m wondering when we will see some non-L kit lenses. Now that the RP is out, Canon could use a few low cost zooms to help people move over to FF.

You think an EF to RF teleconverter would not add that length? I'm no optics engineer, but there would still be the flange distance to deal with. That isn't going away. Who knows? Maybe it is possible. I don't think so though.Of course, but why add length to an already lengthy package.

IF you need a decent ultra wide angle lens, L lens for sure, cheap lens won’t give you great result.Then I have no reason to buy a RF mount. I can just keep using my old 6D.
