Have searched a bit both here and internet in general, and not finding a definitive answer.

Have the EF versions of the Tamron 24-70 f2.8 G2, 70-200 f2.8 G2, the 150-600 G2 and a 35mm (f1.8?) prime (along with a few other non-L Canon lenses). When I can get things right, they all produce pretty decent photos on the bodies I have.

Tamron indicates they function on the R & RP, but I haven't been able to find anything about compatibility with the R5/R6. Wondering if they will function (together) with the IBIS. Or if the lens stabilisation will just need to be turned off. And if the body IBIS will work with the lens IS turned off with 3rd party lenses.

Anyone had any experience or knowledge on this that you could share?

About to pull the trigger on an R6. Won't be a factor in ordering the body, but may influence what my first RF-"L" lens will be...

I can’t swear this is true, but since both the sensing and IBIS are internal to the camera, I would think they would work with any lens, but perhaps someone who actually owns the camera can comment.

I can only reference theory: the IBIS is used for any attached lens. The EF to RF adapter is camera independent. Tamron's confidence for the EOS R / RP bodies should extend to the EOS R6 and R6 bodies.

You have 'fast' Tamron zooms. You might replace with the correspond RF lenses, or even an even faster f/2 24-70? The new RF 70-200 designs, both f/2.8 and f/4, are new designs and very compact. You'd have to decide from your own shooting style which would / could be your most used lens, maybe even the 24-105 options. If you're into wildlife, or want to join, consider the RF 600 or 800 primes.

That's kind of what i was thinking, but hoping maybe someone out there has "tried it". Not that it matters. I know the lenses will work on the R6.

The 24-70 pretty much lives on the 6DII. Back when we could travel, shot a lot of landscape with it, and here locally a lot of sunsets.

The 150-600 is on the 90D almost all of the time, and sits by the back door. I'm still working on figuring out that setup.

Probably because I haven't just dedicated a couple of walks with it, but I don't find I use the 70-200 that much.

Kind of leaning toward the 24-105 F/4 L to start with, and next either the 35 f/1.8 macro or the 85 f/2.

After I see if/how the R6 works with the 150-600, one of those long f/11 primes may be in the works. And of course a 50mm prime.

I'm tempted by the R5, but hard to justify all of the other associated cost...

Thanks for the reply

The only third party lenses I have (Sigma) don't have IS and the IBIS doesn't work by itself, I thought it would and was disappointed IBIS didn't work on my Sigma 105.

Shouldn’t matter if the lens has IS as long as the body has IBIS. What body is it?

knutte

yes it does actually. Forgot to mention it is R5

That’s very interesting. Wonder if you’ve spoken to Canon about that? Just wondering if it could be a menu setting?

See Ken Rockwell's review of the Canon RP. He points out this camera, and all the other "R" cameras can function with ALL EF lenses. I have two, one new and one used, and so far he's absolutely right. Because the diameter of the lens mount is so wide, and Canon (according to him) hasn't changed the EF connection system since the 1980s, everything works fine. I would advise getting a genuine Canon adapter (only $99) since moves one complication from the equation. Because of the wide variety of inexpensive used EF lenses that are available, I've now converted entirely from the Sony to the Canon system.

My query isn't relevant to the R/RP. It's been well established that the adapted EF lenses (even third party) work on those. Tamron has officially indicated that for quite a long list of their EF lenses.

But the R5/R6 with IBIS are different animals. I've done a bit more "research" since I posted this, and seems like even many of the Canon EF lenses with IS are a bit hit and miss in terms of the IBIS+IS. Found an article that commented about the difference in communication speed capacity between the camera and lens, and that the RF are much faster than the EF. So even if they are both "working", sounds like they may not be working "together".

Being a bit of a technonerd, that makes some sense to me.

Guess I can be a guinea pig. Just need to hit the "place order" button on an R6 with a 24-105 f4 L and an adapter. Would like to get the control adapter, but they aren't to be had right now...

It will have to ship to Miami, get on a plane and clear customs here, so likely be 2-3 weeks till I get it. I'll mess with it and come back to post what develops...

Thanks

Why not get the rf 24-105?

Raybo Loc: George Town, Grand Cayman

Sorry... Wasn't clear. It is the RF24-105 f4 L. The adapter is for all of the EF lenses I already have.
