Third Party Lenses

SIGMA will address the RF mount in 2022 [CR3]

I don’t have a lot of reliable sources for SIGMA and Tamron, which isn’t for a lack of trying.  One of the most asked questions I get is “when will SIGMA and/or Tamron launch RF lenses?” With my answer usually being that I have no idea.

That may have changed this week, as a good source for other areas of the industry told me that at least SIGMA would be addressing the RF mount in 2022. While the source wasn’t privy to the actual roadmap, they did think that we’d see 3-5 lenses announced for the RF mount in 2022. The biggest roadblock for SIGMA is apparently manufacturing capabilities beyond just the issues from the pandemic. This does make some sense, as SIGMA has said in the past that keeping up with demand is an ongoing challenge.

As for Tamron, I haven’t heard a peep about their plans.

More to come…

I'd love the newest Sigma 85mm f/1.4 in RF mount. It's roughly the same size as the Canon RF 85 f/2. I dig what Canon has done with their f/1.2 lenses, but they're significantly bigger than the EF versions and with the smaller mirrorless bodies they just don't balance well. First to get some decently compact f/1.4 primes out gets my money.

I really hope it's true. I'm crying Everytime I see new 3rd party lenses for FE mount but nothing for RF.
I actually recently decided to not invest anymore in glasses for my R6 and instead buy a second camera but this time from Sony. I will keep my R6 for 4k 60p and the superior RF 70-200 2.8 for stills.

Using 3rd party glass on Canon or Nikon is probably going to work out just fine, but it defeats the whole purpose of having these mounts with the wider diameter.

But are they going to have the full R-mount capabilities, whatever those are, or are they going to be EF lenses with an R mount, just to get away from using the adapter? There is also the issue of the Nikon Z-mount and the Fuji X-mount.

But those would have to be new lens designs who really take advantage of the RF mount. Not just an RF version of the 105mm f/1.4 Art for example. Then I would rather buy the EF version that still works on my other cameras.

"The biggest roadblock for SIGMA is apparently manufacturing capabilities beyond just the issues from the pandemic."

But the experts on this forum keep telling us that it is Canon's fault that Sigma has yet released any RF lenses. Don't tell me they are wrong!
I would like to be proven wrong if delay was only pandemic related and not licensing related. In any case I will be eyeing their Macro lens and one of their 24 f3.5 DG DN(or Tamron .5x primes).

That might be true in the case of Nikon. However, the Canon EF and R mounts are the same diameter.

Consider the Sigma DSLR Art lenses designed for both the Nikon F and Canon EF mounts. The F mount is much smaller than the EF mount but Sigma seems to have compensated. For FF DN lenses, the smallest lens mount will be the Sony FE, which is about the same diameter as the Canon M mount and the Nikon F mount.

What? Not at all. The Sigma 85mm ART for EF is more than double the weight, and bigger of course. Similar to the RF 1.2 you find to heavy...
There are 2 sigma 85's. He means the mirrorless only one that currently doesn't exist for Canon thus mentioned the newer one and would like to see suggesting it doesn't exist. It is indeed much lighter and smaller than the old one. You're right on the size and weight of the EF old one thus I'd also like to see a lot of RF versions of the mirrorless only sigmas that currently Sony E and Leica only mounts. I never carry my sigma 85 art EF unless I really have to for the reason the size and weight and I'd swap out myself if they start making RF versions of those Sony E and L mount options.

I think padam meant that Sigma or Tamron probably won't design the RF lenses from scratch, but will use the same designs as for Sony FE, and those will not be able to taka advantage of the larger RF throat.

Which should give Canon and especially Nikon a competitive advantage, their larger lens mounts allowing them to make better lenses at a lower price. Anybody care to bet whether they will actually do that?

I love me some Art glass and I need a FF 24-70. But the EF 24-70 isn't at the same level as most of thee rest of the Art glass so I am hoping it comes early in the road map which is likely. These will definitely be the same mirrorless lenses we have seen for Sony just with a different mount since that is how all their previous lenses worked.

BTW my biggest beef with the EF 85 1.4 Art is that is needs an 87mm filter. If you are shooting wide open in daylight even with the shutter at 1/8000 you are going to need an ND quite often.

Compared to a 1/8000 s shutter speed, the R3's 1/64000 s shutter speed is like adding a 3-stop ND (which is what I typically use for outdoor shooting with my EF 85 mm f/1.2 or 1.4 IS).
