That max mag ratio is quite insane and will be very useful for wide angle macros.

Canon has no hope for the RF-S system. This lens is just the replacement of EF-s 10-18. But their kit lens could follow the EFS 18-55 F3.5-5.6. Instead, they made 18-45mm F4.5- 6.3, where it could be 3.5-5.6. Canon has huge potential at this time regarding R50 and R10 but lacks a prime like 22m F2 or an overall zoom lens (like 17-55 F2.8) or a good kit lens hampering their sales.

F4.5 lens .at this point I rather use My phone . Canon budget releases are so ridiculous and unworthy of buying .that's why they blocked 3rd party lenses. Because who would buy this over the sigma 10-18mm

It’s disgraceful what Canon is doing with third party lenses.

if you are looking to adapt ef lenses you can get the Sigma 10-20mm f/3.5 EX DC HSM Lens for Canon EF. it costs about $250 and works really well.

These new rf-s lenses are so underwhelming. They might as well have kept the ef-m line alive, those are some wonderful little lenses!

Thanks for this early look. 😎 Now I am really disappointed!!! Tamron has the 11-20mm f2.8; Ok it's bigger and heavier but Sigma offers the same focal length in the 10-18mm f2.8 with only 100 grams more weight BUT WITH CONSTANT FAST APERTURE! For shooting with an R7 indoors it's absolutely necessary to have as much light as possible.

I think the failure of the eos m series was due to not releasing lenses quick enough. I loved the ef-m 22mm f2, 32mm f1.4 and 11-22mm lenses and was really hoping for a camera to be released with IBIS, but that never happened. I pray to the camera Gods that they’ll release these quickly and my preference would be some kind of range finder styled camera with IBIS

There are plenty of crop (RF-S) format third party super wide lenses if (and only if) you are willing to give up autofocus. With a lens this wide, we each must consider just how important autofocus is to what we do. When you do your final review, it might be good to compare image quality and other features from some of the manual f/2.8 options from Laowa or NiSi. Of course there are also the 9mm lenses that do cover full frame all for the same speed reduction. Also a final review needs to address whether the fall off of corner sharpness is caused by field curvature or is just fuzzy at all distances. Test charts can be deceptive when you get this wide. One effect to be expected with these new releases might be the used price drop from those trading in their previous models. Whether we upgrade here will be dependent on image quality making your upcoming tests most interesting.

Why are RF series lenses so ugly. EF-M lenses had so much class to them.

Left Canon for Sony, and this release just shows how right was that move.

alternative Tamron for EF 15-30 full frame, much bigger but f2.8 all the way. Very sharp and second hand prices under 400

Thanks Gordon, I'd love to see an image comparison at 10mm of this and the EF-S 10-22mm at F3.5.

Why can't they just call it 16 to 29 mm???? Do camera companies really think APSC users care what's listed on the lens when you're talking about what it is in full frame when it's not a full frame lens. If it's an APSC lens just give the focal length of what it is geez. If you can't achieve 10 to 18 mm why listed on the lens I'm just confused why they do this

I really think that Canon isn't doing this for real, but to make fun of poor users of the RF-S system.

Thanks for not forgetting other options.

What? Not f/7.1 on the long end? lol

I hope Canon will make a prime RF-S lens of 10mm with a minimum aperture of 2.8 or smaller. This zoom lens with an aperture starting from 4.5 is not very appealing for me.

My camera is R7. I can't wait to buy the new wide-angle lense.It's enough lightweight and impact.Good for Vlog!

Well, I'll likely purchase it for my R7 hiking kit, but I won't be very enthusiastic about it. I would really like to have some wide-angle options that are up to the quality of the R7 capabilities. I have my collection of ff R lenses, but they're just too heavy to take up the side of a mountain with me. I'm not getting any younger. :-)

It really does feel like the RF mount and it's large diameter mount absolutely wasn't designed with APS-C sensors in mind... I wonder if they were initially imagining the EF-M mount and RF mount co-existing together early onwards, and then couldn't backtrack on the RF mount by the time it became clear that having 2 separate mounts simultaneously wouldn't work out?

Given the market segment this lens was designed for, this looks like a decent addition to the RF-S line-up. I don't intend to acquire any RF-S lens for my R50 as it can "make do" with the EF and RF lenses and adapted EF-S 10-18mm. If I want to go "dinky", I'll use the M50 and EF-M lenses.

Tokina 11-20mm atx-i f2.8 is also another solid contender for aps-c wide zoom.

Why is it a 4.5-6.3 instead of the common 3.5-5.6? The mount was too tight to design?

Kinda neat how view counts have roughly correlated with focal length on the latest three RF treats. It's ok lil tenner, I'm here for ya. Keen eyes note that you are at the same facility for some of the B-roll taken with the big full frame 10-20. Is it common for manufacturers to stagger embargoes this much on the same briefings?

Same list price as nikon's excellent 12-28 in the UK, and an entire stop slower over the shared zoom range (the 12-28 is only f/4.5 at 18mm) - the only advantages to the canon lens are an extra 2mm in 35mm FoV terms and a smaller design that'll suck dust into the lens. The RF-S bodies really deserve better.

When I heard about a 4.5 to 6.3 lens I wonder who's gonna buy an equivalent 7.2 to 10 in full frame?

If the optics are slightly better then the old version then that's nice. 11 aperture blades sounds really out there.(is that correct? From BH video). The f6.3 aperture is rough...though honestly for my landscapes on crop I'm always shooting at 6.7 or 7.1 Tonight trip over the diffraction barrier. But to be unable to go brighter than that is pretty sad especially for normal users who will have to crank that ISO up something serious.. Cannon's Auto ISO has never been conservative to say the least. Unfortunately with Canon there's always a caveat no matter what you buy. Good luck to RFS users, you're still going to need it. I can't imagine what they're going to do with the prime that eventually comes out. It's probably going to be stuck at 2.8 and be plastic.. and ugly cheap build.

It’s a very compact lens, I would hope for an RF-S 10 or 11mm f1,8. make it more expensive but this would indeed be great. I did use the EF-S 10-18 on my R7 and it’s a good combo, as I normally just shoot on 10mm, max 12mm, the lower aperture on the end would not bother me. Let’s hope for sigma and tamron in the long run but at least a neat small lens now which makes the travel bag not too heavy. Combine it with the RF-S 18-150 and you can cover a lot with those… Thanks for the great overview Gordon and also your own thoughts. It really is appreciated 🙏🏻

That's why Canon is no no without alternative lenses from Sigma or Tamron. That f4.5-6.3 is a slap in the face..

Hopefully those claims of it being sharper than the EF-S 10-18 are true. I owned two copies of that lens, both obviously decentered and soft even in the "good" corners. I moved on from Canon APS-C to Olympus for my backpacking landscape system, but would look hard at this lens plus an R10, _if_ the sharpness is there.

If R7 is used with RFS10-18. Then there will be some distortion and warping when shooting videos.

informative lens review.

I own an R10 and I am looking for an overall zoom lens like Sigma 17-50mm F2.8 IS or Canon EFS 17-55 F2.8 IS. For prime, I am happy with 24mm F1.8 IS (please fix the price of this lens at 479USD or 499USD permanently).

I'm waiting for this lens

What Variable ND Filter Can I get to work with this? Just placed my pre-order today.

f4.5 to 6.3! I think I'll stick with my 10-22! Although i'm keen to see how sharp it is.

Canon and Nikon don't want to make proper crop lenses. They completely loosing to Sony and Fuji in lens selection

Might be worth checking out. I wonder how it compares to my old EF-L FF lenses in terms of sharpness. Been using the 17-35 L on my R7 but could do with being a little wider, lighter and not needing the adapter

First item on my Santa´s lisy this year

Why does it have a brim

Why do they make those rfs lenses so you can't attach a Lee or formatt hitech filter set😢

It looks like an overpriced "cheap" lens to me. Thanks to the policy of closing the door to third party lens manufacturers Canon can charge whatever it wants. I love Canon, but brand loyalty is not my cup of tea 😏

Looks great what’s the difference between this lense and rf 16mm f2.8 honestly I am on the process of buy one or the other

canon no need to release RFS lens tbh, RF lens for FF sensor can be used in cropped sensor camera

How about image quality and distortion?

This is humiliating when Sigma just launched 10-18 2.8 for APS-C

I guess this lens has its place but again its pretty underwhelming. Cheap looking is how I'd describe it. No doubt Canon will over price this just because they can.

Canon lens releases are getting embarrassing…. !!!

No thanks. I'll stick to the EF-S. RF is only a premium for a smaller size in my opinion.

with this angular, now I switch to canon APSC-RFS

I think Canon was more concerned about the compact design than the aperture because they wanted to appeal primarily to vloggers. Unfortunately! I was hoping for a good lense for landscape photography. This one seems to be to dark.

Give us an F4 rfs lens or even better a 2.8 👍

Yeah I'm gonna wait for that sigma

Thanks for the review. Looking forward to the full review and comparison with the EF-S10-18. But so far, it seems Canon came up with another kitlens. Seems as far as RF-S goes, Canon has again dropped the ball.

How the HELL does Canon think they should be selling a lens that expensive with a plastic mount? That's just wrong.

EF S rehash but now charge $329. How nice for Canon

This is a mockery. We want 2.8 or lower

Best🥰

F 8.6-12.3 😂😂😂

Poor Canon. No leadership at all.

Typical Canon, always making the crop cameras useless. good thing I switched to Sony.

Sigma just released a 10-18 2.8 for Sony, and Canon does that! This is probably the worst lens to release, it's a shame
