Third Party Lenses

What’s happening with third-party lenses for the RF mount?

A lot of people are asking when we’re going to see the big third party manufacturers like SIGMA and Tamron enter the RF market. Canon’s L offerings, while terrific across the board are definitely at the high-end of cost in most cases.

This is where SIGMA and Tamron have fit in over the last few years for EF, terrific performance for a fraction of the cost. Both SIGMA and Tamron also have unique offerings for Canon EF shooters, and we probably want that to be the case for the RF mount as well.

SIGMA

SIGMA CEO Kazuto Yamaki hinted at the development of RF mount lenses in a recent article saying “which is why our short‑term strategy indeed involves a possibility of introducing lenses with new mounts – to such photography systems as Nikon Z or Canon EOS R.” I would go as far to say that R&D on the RF mount has already begun at SIGMA.

What I don’t think we’ll see from SIGMA is just mount conversions of current lenses. The business plan from SIGMA has changed over the last decade, and they aren’t simply just designing cheaper offerings, they’re designing great offerings. The RF mount flange distance and control ring offers some unique opportunities for SIGMA to introduce some really nice lenses, as they have EF.

I expect we’ll see something announced later in 2021, but the challenges of COVID could obviously delay the timeline.

Tamron

I haven’t heard anything about Tamron’s RF mount aspirations, but I imagine they are working on it already. I wouldn’t at all be surprised if Tamron gets to market with a native RF lens or two before SIGMA does.

However, there are still a lot of third party offerings for the RF mount, but only Samyang/Rokinon offer autofocus RF mount lenses, while there are many manufacturers that are offering manual focus lenses, some of which are quite unique.

Below is a full list (as far as I can tell) of RF mount lenses available from reputable manufacturers,

Note that this list does not include cinema lenses.

Samyang

Samyang has both autofocus and manual focus lenses available for the RF mount, they are currently the only third party manufacturer with autofocus lenses for your EOS R series camera.

Autofocus Lenses

Manual focus lenses

Rokinon

Rokinon lenses are the same as their Samyang counterparts but pricing can be different between the two versions.

Autofocus Lenses

Manual Focus Lenses

Venus Optics

Venus Optics has been investing heavily into RF mount manual focus lenses, and they have a lot more new lenses on the way for 2021. Currently, Venus Optics is the only company that offers a native tilt-shift lens for the RF mount.

Manual Focus Lenses

NiSi

Nisi recently launched their first RF mount, a compact wide-angle lens with 10 aperture blades to produce a star effect to lights across all apertures.

Manual Focus Lenses

Lensbaby

The maker of quirky artistic lenses makes two native RF mount lenses, with more coming in 2021.

Manual Focus Lenses

Meike

Another small manufacturer that has been making manual focus lenses for a while now. They are perfect for people on a tight budget.

Manual Focus Lenses

Kipon

Kipon makes a series of classic design prime lenses for the RF mount. The lenses are equipped with an aperture ring.

Manual Focus Lenses

Mitakon Zhongyi

Known for their Speedmaster lenses, Mitakon Zhongyi makes the only native 50mm f/0.95 lens for the RF mount.

Manual Focus Lenses

7Artisans

Currently, 7Artisans has one native RF mount available and another one which will be available soon, but I expect we’ll see more in the coming year.

Manual Focus Lenses

TTArtisan

A manufacturer that I am not too familiar with, but they do make an inexpensive fisheye lens for the RF mount.

Manual Focus Lenses

Brightin Star

To be perfectly honest, I have never heard of this manufacturer. It does appear that they sell the least expensive native RF mount lens on the market.

Manual Focus Lenses

Funleader

Funleader makes a “cap lens” for the RF mount. It’s less than a pancake, so I’ve called it a crepe. I own one of these, but due to the current movement restrictions, I haven’t been able to go out and do what I want to do with it.

While only Samyang/Rokinon offers them right now, I think that with MILC largely eliminating the difference in autofocus accuracy between native and 3rd party glass, there's never been a stronger reason to invest in these cheaper lenses.

I think we may end up needing a different term to describe RF mounts from third parties if they're not *true* RF (using high speed protocols, with control ring)

Because, as we all know, it's a lot easier just to use the mechanical mount of the RF system but send the 1987 vintage EF protocols to the camera - which Sigma and the other third parties finally understand after quite a long time of getting it almost but not quite right.

I'd call them EF-R lenses, for lenses using the RF mount with EF protocols..

Does it really matter?

I doubt that an 'EF-R' lens would focus as fast as a native RF lens could. They still could be very good lenses, maybe the difference won't be that much in real world use. But I would hesitate to call them true 'RF' lenses.

I don't think so, they are lenses with native RF mounts, I don't care too much about what optical design they use or if they use the EF or RF protocols. Canon's RF 50 f/1.8 is basically a 50-year-old optical design with a few tweaks and updated element types and the control ring. Whether or not they're manual focus or autofocus doesn't really change that. Making up a name like "EF-R" would confuse everyone.

I have the Sigma EF 70-200mm F2.8 DG OS HSM on my R6, and I don't know if it's physically possible to focus faster than that lens does.

I'm really interested in getting a third-party lense for astro shots as soon as movement restrictions allow me to go to dark sky places. Does anybody have any experience on the following lenses:

Laowa Venus 12mm F2.8 Zero-D
Laowa 15mm F2 FE Zero-D
Samyang RF 14mm F2.8

I'd really appreciate every feedback on either one of these lenses.

I use to own the Sigma EF 20 F1.4 but I wasn't entirely happy with it (not wide enough/ RF Lenses seem to be way sharper & less coma etc.) so I sold and I've searching ever since.

Does not paint a good picture for aftermarket RF lenses with AF, they will need constant updates.

But I am fine with using adapted EF or Canon RF lenses, they work just fine, I don't see the point of buying into the RF system to use aftermarket glass when the whole point is to have that wider mount diameter with lenses specifically designed for it.

3rd parties design glass specifically for RF mount cameras, too.

I have had no issues with my EF Sigma 35/1.4 mounted on an EOS RP with the RF adapter.

I wonder if Alex Barrera's problems with the Samyang AF 85/1.4 have more to do with his R5 than they do the lens, and I have read previously that once the R5 updated to the latest firmware, problems with the Samyang were eliminated. I cannot confirm this with my own experience just yet.

EDIT: many commenters on the video are saying that with version 3 camera firmware, the lens works just fine. It may not be a lens firmware issue at all.

I can highly reccomend the Kipon offerings. I have the 75/2.4 and its fantastic. A friend of mine has the 35/2.4 and has used it in nationally published commercial architectural photo shoots. I plan on picking up one of them soon too!

They are small and light, yet feel solid. Full metal construction. Styling is very Leica-esque. Image quality is great, and the rendering sharp, but with a nice sense of depth. The only trade off is full manual control and relatively slow max aperture.

In his interview, didn't SIGMA CEO Kazuto Yamaki indicate that they are already operating at max capacity? That would suggest they can't introduce a new lens until they either expand capacity - which didn't sound like 'the plan' in the interview; or discontinue a less popular product to free up production capacity.

So it might be a little while. I'm looking forward to a SIGMA ART in RF.

It'll probably be the latter, there is always dead weight in a lineup.
