These are all of the third party lenses for the Canon RF mount

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.
My only manual lens is the Samyang XP 14mm EF F2.4. Stars don't move much in distance - so I'm keeping it. Can hardly be beat imho.

We are lucky that third party lens makers have gone high-end since its what modern cameras deserve. I remember that - to my surprise - the otherwise great 70-200 IS L f/4 showed slight weakness compared to the 70-200 IS L II/III on the 5DS/R. Something not noticeable on the 5DII/III (never compared with the 5DIV). I for one plan to expand my current RF lineup with whatever lenses work best on the fabled R5S once it arrives. More choices is just better. ( I know all lenses perform better with more MPIX, but relatively the differences kick in).

Hi, I am interested in precise and fast autofocus RF compatible lenses, if possible. Manual focus is tricky, time consuming and for example in very low light conditions hard to use.
I am interested also on very fast and bright lens with an aprture btww F/1,4 and F2,0 and possibly a wide angle lens like a 10 or 12mm to shoot landscape and astro photography.
Currently I have the Samyang 12mm F/2,8 ED AS NCS fisheye with EF mount and I use it in combination with the RF adapter for my R5 camera. Results are good but of course this lens suffer about achromatic aberration....

Hi! As of right now, there is only one wide angle RF autofocus prime, the Samyang/Rokinon AF 14mm/f2.8. There is also the RF 15-35/2.8 wide angle zoom. There is nothing wider available in autofocus, in RF mount, right now.

However, if you can find an autofocus lens you like in EF mount, you can probably use it on an RF body with the EF/RF adapter. Hope this helps - good luck and happy shooting.

It's not just about autofocus performance with third party lenses. Stepless aperture (google Tamron video clicking noises), color rendering, bokeh rendering, corner quality, and build quality/durability are all factors to consider, where Canon L glass usually come out on top (there are exceptions of course).

But third party lenses excel in value that Canon can't touch for several reasons. First, they have economies of scale across systems. As others have mentioned, they aren't making a lens specific for the R system, that R lens is probably available on several other mounts. Second, they don't usually cater to the professional crowd, which demand levels of durability and serviceability that affect design and materials (see for example Roger Cicala's breakdown of the Canon 35L versus the Sigma Art 35). Not to say that third party build quality is poor, but as Roger shows, definitely not at the same level as Canon. And finally, they don't ensure compatibility with the endless body/lens/extender/flash/etc combos possible in the EOS system at the same level as Canon does, meaning less time spent on testing and compatibility.

The above doesn't exactly put third party in a positive light, but they might have a place depending on your needs. For example, if there is a focal range that is not used often, but still needs to be covered, third party can be a low cost option (someone earlier mentioned an ultra-wide prime for a few hundred dollars just to play with). Or maybe one prefers a high quality f/1.4 or f/1.8 prime that Canon doesn't make. Or maybe it is a niche focal range. Etc. Third party offers more choices at usually much lower prices, so I'd rather have more choices versus less choices. But they do have their place. If budget allows for it and it's a focal range used often, I will almost always go for the Canon L.

In that interview, which partly can be read at DPREVIEW, the CEO of Sigma made a statement that needs to be thought about. He said that they will remain a photographic company producing lenses and cameras for “as long as possible.”

when you say that, you’re already thinking about the time when it won’t be possible. That’s a very negative statement, and I wonder if he realized it when he made it. Everything else in the interview needs to be tempered by that one statement.

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.
Mount diameter is the same for EF/RF.

I think without COVID, 2021 would have been the year for 3rd party RF support to hit full swing. Really, before last year the EOS R and RP were kind of middling, and canon appeared to be still fully committed to the DSLR with the release of a new flagship 1DXIII. The R5 and R6 then hit, and became the two top selling cameras. With now lots of traction on this mount, the 3rd party guys will be hot to get in on the sales. They see both the need and the profit margin - with canon's prices so high they can price higher but still be less than Canon, and get more profit per lens since those likely share at least some R&D cost with versions for other mounts.

The Sigma guy interview - I wouldn't read too much in to it. If the company is really fully committed to their current product line, and has an R&D pipeline full of new lenses for it, then they will be dinosaurs soon. They have to see the writing on the wall for the DSLR line, and if they really are committed to continuing to produce camera lenses 'as long as possible' then they will have RF mount lenses as part of that future. I read what he says as typical corporate speak. They aren't ready to talk about what they are going to release because they aren't ready to produce it, and they don't want to tip off the competition and get beat to market.

But this is obviously just my take, I don't have any inside info.

Corporate speak is positive. It can also be confusing. But when a CEO makes that kind of statement, it’s something to consider. After all, he knows far more than we do about what’s going on. My contacts don’t say much about that.

This pretty much sums up why it's looking increasingly likely my next camera will be a Sony, despite my preference for Canon's ergonomics. I'm actually a little sad about that given how much I've enjoyed my Canon gear and the fact that I think Canon gear is generally good quality. But the lenses available for the Sony system, including third party lenses, and their price, are making the Sony system just so much more appealing to me than the Canon system. I realise most of the R system gear is fantastic, and for some people it is exactly what they want. For me, though, the range of smaller and lighter lenses with good IQ, at relatively affordable prices, available for the Sony system is much more of a draw card. I'll hold on a while yet on case things might change for the RF system, but at this point I don't think it will change soon enough for me.
It probably won’t. I was speaking about this on another thread and something became apparent to me. Sigma is over performing in sales with EF lenses and sigma had a couple of M-mount lenses that were supposed to be released and now that M-line from canon is expected to be discontinued. The other thing is the in body corrections don’t exist for 3rd party lenses. It doesn’t make sense why 3rd parties are having to reverse engineer everything. It seems counter productive if this is going to be their main line for the future. But lens and camera rental sites did show that DSLR’s and DSLR lenses are still remain supreme in gear being rented for canon and Nikon despite mirrorless options. So idk. Maybe everyone is just going to have to be comfortable with higher priced canon lenses or comfortable using an adapter.

are the 3rd party lens using RF lens protocol or EF lens protocol?
There are limitation with EF tech. One example, RF interface has more data bandwidth which allows for more data i.e. OIS integration with IBIS etc. Canon surely has plans to further add features. if these lens are using EF tech, it may limit taking advantage of future R systems features.

Language issue? Perhaps he really meant to say that they are a photographic company and have no plans to change from that?

As opposed to Canon, who does many different things.
