Finally received my 14-35 f4 and used it at Ricketts Glen State Park almost exclusively.
A very fun and lightweight lens to hike with! The vignette was a pain in some photos, just used PS to clone.
All in all I’m extremely happy with the inclusion of this lens to my kit.
14mm to 500mm all use a 77mm filter!

Got my 14-35 today. May be my copy is not as sharp but my 16-35 f4 is still sharper. Processed using Dxo Photolab 5 and Lightroom. Did anybody else have the same experience?

I was disappointed at first, until I changed from the mechanical shutter on the R6 to electronic first curtain. That did the trick for me.

Interesting. Is that a common problem with the mechanical shutter (perhaps causing vibrations that can decrease sharpness)? I haven't looked into it; I haven't seen a compelling need to move away from the electronic 1st curtain.

I don't know whether it is a common problem. Initially I set the camera to use the mechanical shutter, just because that is what I have been using my whole life with SLRs. I didn't give it much thought. Soon after, the 14-35 mm arrived and I noticed inconsistent behavior and an overall disappointing image quality. It took me two days to figure out that the mechanical shutter was the culprit. I didn't notice shutter-induced blur with other lenses, but I haven't performed any systematic tests like I did with the 14-35 mm.

My experience is different than yours. My new 14-35 is very sharp, using it with DXO Photolab 4 and Capture One. I don't have the EF 16-35mm f4 lens to compare it to. I am especially surprised at how sharp the 14-35mm is at 35mm setting at infinity focus.

Thank you for your detailed reply on the different sliders in Photolab. I have been tinkering with them and have tried mechanical, electonic first curtain and electronic shutter with and without the IS engaged at equivalent focal length, aperture, exposure time and ISO. Usually 16-35 f4 seems to out perform the 14-35.

May be I have a particularly sharp copy of 16-35 or particularly crappy copy of 14-35. 14-35 is certainly lighter and smaller but finding it harder to justify spending $1000-$1100 extra on it after selling 16-35 if there isn’t any improvement in quality. May be I need to try out a 15-35 f2.8 and see if that is better.

I mainly take wildlife pictures, so 16-35 f4 and 24-70 f2.8 are my least used lenses.

My 14-35 is going back to B&H. Hopefully someone in the waitlist has a chance to get the lens. It is compact, light and a great UWA lens, if I didn't have an incredibly sharp 16-35 f4 and if I used the lens a lot more in my usual photography I could certainly justify keeping it.

Today's LR/ACR updates include a lens profile for the RF14-35. Looking forward to assessing this lens in more depth, and being able to process using Adobe.

I just got the LR update and am looking at some samples posted here. Even at 35mm and f/11, it still vignettes which surprised me. The LR profiles do a good job cleaning things up though.

I think you are most likely to see the least vignetting at 20mm or so on this lens since that’s when the lens is collapsed.

Yeah it definitely falls off rapidly as you get away from 14mm. For my needs, I'll take the more compact lens and software corrected vignetting that I might crop away anyway.

Just received my 14-35 and my first impressions are very positive. It's definitely sharper than my 16-35 f/4.
Vignette is strong specially with the formatt hitech filter holder and CPL, but it's very easy to correct in post.

Quick test with the holder and CPL.

Are your filters "low profile" or standard? I'm not sure any other lens goes to 14mm on a 77mm filter.

After flirting with my copy of the 14-35mm, I too have now decided to return it for a refund. The lens is in my limited experience best from 24-35mm. The sample I received was especially sharp at 35mm.

I was disappointed in the image stabilization, which is the only real surprise. It's good, but not that much better than the Sony/Zeiss 16-35mm f4 OSS on an A7RIV, which was very surprising to me.

Also, from 16-20 mm and perhaps through 24mm, the Canon is not as sharp as the Sony/Zeiss 16-35mm or Sony 16-35mm f2.8 GM. . . . I'm thinking it may have something to do with the anti-aliasing filter on the R5. I don't know. The Canon R5 and 14-35mm is also quite a bit larger than the Sony camera and Sony Zeiss 16-35mm f4.

I'm disappointed in that I was hoping to be able to convert completely from Sony to Canon, but for now at least I've decided I'll be happier keeping my Sony A7RIVs and Sony lenses for wide-angle uses, and the Canon R5 for use with the RF 70-200mm and EF 70-300mm, f4-f5.6L.

I'd rather have one, not two systems, but each system has its own benefits and compromises, and its own lenses for which the other doesn't have (for me) substitutes that I am all that happy with.

I'm also grateful for the amazing choices we have in camera equipment today.

I was starting to wonder if I was in the minority of the people who weren't enamored with the 14-35mm. Sure every lens/camera system has some minor quirks that we learn to work around. For instance 14-35 being sharper in EFCS(not my personal experience) even though it shouldn't matter if the shutter speed is over 1/1000sec.

I systematically checked it through the whole range esp. 16-35mm in every combination of IS on/off and various shutter mode and speeds and was disappointed compared to 16-35 f4. I would have gladly kept it If it was sharper in the 14-24 range. 24-35 range overlaps with the 24-70 f2.8. For me pros in favor of 14-35 were that it is 0.4 lbs lighter (.15 lens+.25 ef-rf adapter, UWA in a compact body, changing completely over to RF lenses and of course who doesn't like new stuff

I agree we are certainly spoiled for choices in camera equipment.

This lens is not obvious for me and I do not 100% understand the intent behind.

I now have R5 and do not want to use adaptors, so I will only use RF lenses.

Previously I used to have 16-35 F/4 IS on 5D MKIII. It was sharp, light and I was using it for landscape photography. Great UWA!

If your are into landscapes only and need RF, then what are your options today?
1. 14-35 F/4 IS, which is what it is (high diffraction and distortion)
2. 16-35 F/2.8 which is bigger, heavier, more expensive. Also, you do not need 2.8 for landscapes.

I was hoping for RF 16-35 F/4 IS. Anyways, maybe one day someone will release a better UWA lens for RF for Landscapes where F4 is more than enough.

Strange lens, seriously. Not really shining in anything particular.
I will need to see if Top Landscapes Photographers will have a say on it and if they will use it. Say Marc Adamus, Sean Bagshaw, Erin Babnik. They are on Canon today.

The extreme distortion and vignetting occur below 16 mm. According to most comparisons, the RF lens is better than the EF lens in their common range. If you were hoping for an RF 16-35 F/4 IS, then this is it. You are not obliged to use it at 14 mm.

Cannot speak with confidence as I did not yet test the lens, but as far as I understand, vignetting and distortion is present not only between 14 and 16 mm and it doesn't go away at any aperture. Could be wrong, but this is what I have read. It has a much worse distortion at 16 mm compared to 16-35 F4 IS
