Pre-ordered, should make a good match with my a7r.

Any word about weather sealing on the f4L?

Highly resistant to dust and water intrusion, enabling shooting even in harsh conditions**.


But complete sealing requires a filter (also from the USA Canon web site):
" Built to function even in unfavorable weather conditions, the EF 16-35mm f/4L IS USM is dust-resistant and water-resistant ( when used with an optional Canon PROTECT filter) for professional caliber ultra-wide performance, everywhere."

That's the same as the 16-35/2.8 II, etc.

Yeah... I'm not sure what aspect of the internal design results in Canon's ultrawide zooms having non-sealed front elements. Is the 17-40 the same?

I imagine sealing the front element would be tricky - with a gasket or other. They way they are designed, and using a filter to increase sealing, makes sense - not that filter glass and mounts are tight.

Yes, however, the 16-35 f/2.8L II's corner performance is mediocre @16mm wide open. I would prefer doubling the ISO at f/4 if the new lens is that good wide open based on the theoretical MTF charts.


I bought the 16-35 II (after a few weeks of agonizing over various compromises) the same day the new lens was released. Astro-photos are one main objective of mine. I have some serious thinking to do with a 15 day return policy. I suppose the 16-35/4 will afford me the Samyang 14 as an extra lens at the same combined price. But one reason I went with 2.8II was to limit how many lenses to hike with into the backcountry. Sigh... First world problems

I will say having all 77mm filters would be nice...

The 17-40L at least, claims to be internally zooming, but it's technically not truly true as it is with the 70-200, the front part actually slides in and out a bit (unless I am not remembering correctly, it's been since like maybe 2006 I think since I've used a 17-40L), but not much and they just kinda built the outer barrel long enough to hide it and it's probably hard to seal that kinda motion up without having a filter on the front to just lock out the whole part from leaks (although they do manage to seal the 70-300L, but maybe the huge extension on it gives room to put a lot of seals (or perhaps that is why the 70-300L is so fatter than fat)).

For specialized applications like astrophotography, where the extra stop in speed is an advantage, there would still be a place for a f2.8 UWA lens. Real lenses will be needed to evaluate other lens characteristics not in MTF charts: "Missing lens characteristics include distortion, chromatic aberration, flare and vignetting."

Yes the 16-35 f2.8 is no astro shooting lens, I agree with Fred

Currently shooting with the samyang 14 and 24 tse at 3.5

I have the Samyang 24/1.4, which is why I was willing some compromise with the 16-35/2.8II (versus Samyang 14)... the 16-35/2.8II and its AF and variable zoom offered other opportunities with general landscapes that the Samyang 14 would not. This new lens complicates my choice for sure.

Although I am a full frame shooter at present, I do sometimes wonder if one day I will save some money and go crop. If the new 10-18 is optically impressive that price tag is very, very encouraging!

The published MTF doesn't give performance in the middle of the zoom range. We saw with the 24-70mm f/4 IS that the MTF was silent about the performance sag @50mm that reviewers quickly picked up on once the lens was out. For me, the most important focal lengths would be 21mm and 24mm. Those also happen to be the focal lengths at which my 16-35mm f/2.8 Mk II performs best - so I have no information yet that the new lens will be an improvement.

Those used to f/2.8 lenses should also bear in mind the viewfinder will be only half as bright with f/4. I know what I'd be getting into since I already have f/3.5 and f/4 lenses.

I never really notice the whole "viewfinder" darkness issue. Only in very low light conditions, when f/1.4 lenses are ideal anyway. But never any real difference between f/2.8 and f/4 lenses.

The EFS 10-18mm f/4.5-5.6 will be a huge commercial success. I see this lens as a Canonís marketing investment (similar to EF 50mm f/1.8 and EFS 55-250mm f/4-5.6) to attract new consumers.

I notice it when I push the DOF preview button, but otherwise going from an f/1.4 lens to an f/4 lens at the same event makes very little difference for me too.

This is the lens I've been waiting for. The price is a little high compared to the 17-40 f/4 but it has IS, better IQ and the range works better for me.
Can't wait for the first reviews.

I hung on to my 10-22 against that very possibility.

Much as i would love a better FF performer than my 17-40L, like all the other new Canon L lenses this new 16-35mm is well beyond my financial means, so that move back to crop might be sooner rather than later.

I am selling my 16-35L mk1 at the same price of this one or say $1100, i am not looking for this new lens and my 16-35L isn't used much as well even it is my best UWA lens, i use 24-105L and 24-70 more on my FF, and since i bought TS-E 24II and also very recent Samyang 14mm i doubt i will use 16-35L again, and not far in near future i hope i am getting TS-E 17, and i am still not sure if i should buy Sony 16-35 over this new Canon lens announced as far i am using Sony camera more nowadays over my Canon DSLR.

Well, those brands don't give us any rest or breath when they announce new gear every 1-3 months, it is like they try to tease us to replace our old gear, i know many will not upgrade/replace because no much budget, but i am talking about those who have budget, and then we are left behind.
