once the prohibition is over, we should have a great selection in the RF mount. Some of these third-party lenses are great. I also like the fact that Tamron is experimenting with nontraditional Zoom ranges. I do like the 20-40 and the 35-150 a lot in the fe mount.

Is there any indication that this is ever going to happen?

There was a post on the rumor site last June that Sigma was bringing a couple of lenses to RF mount in the "next 6-8 months". That window has just about come and gone, haha.

I *hope* this will eventually happen, but so far the only company Canon seems to be working with is Cosina, for chipped MF lenses.

For what its worth, you can actually buy new RF autofocus lenses direct from Yongnuo. There are two versions of the the 85mm 1.8 and a brand new 35mm. Out of curiosity, I bought the updated version of the 85 and can confirm it works well. (It is an internal focusing design and focus is quick, like the EF 85 1.8, and thus a bit more responsive than Canon's RF 85 f/2 STM.)

These lenses have EF lens contacts, so definitely using reverse engineered EF protocols. Interestingly, they have a unique new mount design that requires pressing a button *on the lens* to release it from the body. (This is well done though, and is not a hardship in practice.) I wonder if this allows Yongnuo to skirt Canon's patents somehow?

The YN 85 is actually pretty good, sharp and with much less CA wide open than the EF 85. It does have lots of vignetting and some cat's bokeh in the periphery, but I have definitely seen worse performance. It is all metal and feels and looks way different from any Canon lens though, for those who care about aesthetics.

FIRST, I shoot Nikon because the Nikon N60 (film) felt better in my hand than the Rebel. That is how little I knew of photography. Now, if Nikon put out a body that prohibited 3rd party accessories I would skip it.

Add me to the list of people who will not buy anymore Canon gear until they start adding 3rd party native options. I have had the R6 for 3 years and been great but I also have Fuji X-H2, I am using more. I just got the Fringer adapter last night, using the Sigma 105 on it. OHHHH MY its fantastic!!

I didn't realize this. There were lots of good third party options for EF mount. Why are they not doing this for the RF mount?

To my knowledge, all third party options for EF were unlicensed designs using reverse engineered protocols. This is why many lenses had AF issues or required firmware updates for newer cameras. This probably wasn't anticipated when the EF mount was designed. This is obviously bad for Canon as they make no money from unlicensed knock-offs and lost lens sales. Canon presumably decided to better protect its intellectual property this time.

I suspect Canon will eventually license the RF mount though. It has already begun doing so in a limited way with Cosina in fact. I think they wanted to have a few years of exclusivity to fill out their lens line first.

Unlike Sony, which open sourced part of its lens protocols to attract support when they were a distant afterthought in the market, Canon has not yet been required to do so. But the pressure is on and eventually I think they will open things up, as Nikon has recently done.

We will see.

It’s a huge bummer and the reason I’ve been steering people away from canon, when they ask about camera purchases. So many interesting 3rd party options out ther; it’s a shame we are missing out.

The impression I got from a Canon interview about this topic was that it's possibly not a wholesale opening of the lens mount after a certain date. Rather, it sounded like they would license lens by lens based on how a given lens integrates into the RF system (perhaps interpret this as: how directly it competes against Canon models).

Same here, I would never advise anyone who asks to get a Canon RF system - because there are no AF third party lenses, and no indication they will ever appear. Why do that if EF lenses can be adapted to anything and work just as well. It's only the flashes that will have to be replaced, but since Canon has a new shoe in the most recent bodies anyway, they would have to be replaced anyway.

This has been my impression as well. It's unfortunate as companies like Laowa have just started shipping AF lenses and they have some very interesting designs.

Really all 3 lenses mounts Sony/nikon/canon are not really open. Sony is the most open but not really. I guess they allow any lens to be built but it gets crippled by frame rate and no TC use. Nikon is allow only lenses they want to allow, minimal compared to their own z lineup. I’m sure canon will go the same route as Nikon. At least if they are actually licensed the ones you do get will work properly since they are not reverse engineered

The amount of 3rd party options for the other mounts is impressive. Even the canon ones that were reverse engineered, were really impressive (and never felt crippled) before canon shut them down. The Samyang 85, for example, blew away the canon version (the RF 85 f2). Cheaper lenses that can’t hit max frame rate aren’t really crippled, it’s just up to the consumer if they really need lenses that hit 20fps or lenses that have great rendering, lower pricing and more realistic frame rates. If you need 20fps, you are probably looking at more high end lenses.

Well, seems like I'll have to stay with my EF Sigmas for a foreseeable future. I'm not planning to make a move to the RF lenses any time soon with my R6/2 if there are EF equivalents, although the EF-RF converter makes the camera more front heavy.

All my EF Sigmas are working well and the AF problems are definitely gone by the way of how mirrorless operates.

Agreed. Carrying around the 40mm with an adapter is just so awkward, however.

I'm not a Canon "fan boy", however I believe Canon lens options for their RF system are pretty decent at this time. L glass will always be pricey, but at least Canon offers lower priced options to choose from. Also, their EF to RF adapter works brilliantly well for use with any EF lens.

I have an R6 with several old EF lenses and a few compact RF lenses. I have zero complaints with my EF 16mm f2.8, RF 28mm f2.8, RF 35mm f1.8 and RF 50mm f1.8. They are compact and affordable. Neither Sony nor any 3rd party manufacturer has been able to develop anything remotely similar to Canon's RF 16mm f2.8.

I also own a Sony A7c. I currently use it as my main travel camera with a Tamron 20-40mm f2.8, Viltrox AF 16mm f1.8 and Tamron 28-200mm. Only 2 reasons I use my Sony as my main travel outfit are incredibly amazing AF tracking (light years ahead of my R6) and reliability (too risky to take my R6 with all the stuff I've read about circuit board failure, wobbly hotshoe and overheating). My R6 stays home and is mostly used for local wildlife, macro and other stuff.

Again, I'm not a Canon fan boy or a Sony fan boy. I use each system as needed. On that note, I really wish Sony, Tamron, Sigma or Samyang would make a tiny 16mm AF lens in FE (full frame mount) like Canon did with the RF 16mm f2.8.

I think some decent middle ground in zooms is missing this time. With the mirrorless, Canon could design consumer lenses really dark, preferring the compactness and weight maybe wee bit too much. I'm not sure myself whether making a bit simpler lenses which then get corrected quite a bit in the firmware is the good way, too.

Anyway on the RF now you either have fast(er), big and heavy L lenses, or then dark, small and light lenses. No consumer 3.5-4.5 zooms like they were in EF times, or at least zooms ending at f/5.6 (because DSLR AF forced them

).

The small apertures aren't exactly friendly to the high resolution sensors either.

One of my favorite EF lenses is the old 17-40mm f4.0L. I use it with an EF/RF adapter on my R6 and it works very well. The adapter only adds an extra 1.5 inches of length to any existing EF lens, so you can still use the zooms available for EF mount.

Price is another matter. I find the RF-L lenses to be ridiculously expensive compared to the EF-L lenses of the past. I've only purchased one RF-L lens (RF 24-105 F4 L) and it was a lemon. I ended up returning it. It actually scarred me into not buying the RF 14-35mm f4.0L for fear of shoddy production issues. I still have my old EF-L lenses (17-40mm f4.0L, 70-200mm f2.8L, 100mm f2.8L, 300mm f4.0L), and they are amazing on my R6.

The RF 24-240 makes me forgive that there are no middle ground zooms with fast-ish aperture. Compared to what we had in the old days, that lens is a miracle. The aperture is also decent at shorter focal lengths, f/4.0 to f/5.0 from 24 to 70 mm.
