In other comparisons, the 15-35 seems to destroy it in the 28-35 range, so if that is important for you…

So the 14-35L looks wider - i"m assuming its probably around 32 or 33mm? the 15-35L seems to have a bit more punch and contrast when looking at the roof and net, but that could be because it looks to be a larger focal length.

The way I am looking at the photos, the 15-35 seems wider at 35, not the other way around. Without scientific equipment you can't say if the 15-35 ends at 34 or if the 14-35 ends at 36.

As for image quality - not sure about punch, but I'd say that when you look at the 100% crops of the flowers and wheels, the 14-35 offers more detail.

I'd like to see the 14-35 @ 14 mm (both before and after correction/cropping) compared to a 14 mm prime or 11-24 @ 14 mm.

A 14-35/4 with that size, weight and a flat front element is bound to come with plenty of compromises. I think I can live with them, just as I can with the RF 70-200/4.

Oh okay. I thought that from past comments that the 14-35L is wider than 14, that that difference would hold throughout the focal range. I guess the only way that its really possible to to check without having more scientific equipment is to see how the focal ranges of the 14-35L and 15-35L compare to primes like the 14L, 24L and 35L lenses.

As for the foreground, i also thought that the 14-35L looked more clearer (not sure if its more detail), or if its because to my eyes, the part that has the most detail are large green leaves on the lower left, are really only visible on the 14-35L, but are cutoff on the 15-35L sample. If it wasn't for those large leaves in the lower right of the frame, i would have thought that maybe there was motion blur from wind (but the exposure is for to high of a shutter speed for their to be blur), or that the depth of field isn't sufficient for the flowers (but the laree leaves on the lower left of the frame with the 14-35L are perfectly sharp.

That is correct - it is wider _at the wide end_. However, the 15-35 is wider _at the long end_. That's what my uncropped images show, and what I was talking about.

I shoot mostly people, especially with the 15-35 between 28-35. YMBR, that they optimized this for infinity in those ranges. A little closer and the 14-35 didn't look too hot.

edit: @stanj do you know what those round things are on your neighbors roof? Are they solar panels?

Why didn't you ask right away? Now in better light I just re-did the comparison with the 11-24 included. If there's anyone here who's willing to host the raws for me, I'm happy to share.

Solar heating for the pool. There are two styles - the coils and the straight (rectangular) ones. I have the rectangular ones. Better usage of the roof area, decidedly worse reliability

Now I know that nobody will just take my word for it anyway, but I think I'm selling my 11-24, because the 14-35 is better in every regard except at 11-13, at every aperture, and all that despite not projecting every single sensor pixel. How is that possible, at that price ‽ some may ask?

Right click the image and open it in a new tab / window to zoom in fully.

I know! But how is that possible, I mean it doesn't project a full image circle unlike the properly corrected lenses?

Wow! Thanks for these, Stanj.

And the RF lens does 25mm - 35mm too and costs not far from half the price of the EF 11-24mm.

Were these crops from the middle of the frame? How do both lenses compare nearer the centre of the image, I guess the 11-24mm catches up a bit there?

RF lens vs 11-24mm weighs less than half, has a magnification MFD of 0.38 vs 0.16, is smaller and it takes 77mm filters!

I think that both Stan and Jesse's photos show that the 14-35 is clearly wider than 14mm, and what you see corrected in camera may indeed be close to what you get corrected out of the software. One of the questions is going to be how much effort you have to do in post processing to get it there.

I'd like to get the widest lens I can. the following shot is with the 16-35 F4L, and it was this trip that convinced me I needed to get wider than 16mm, because, I couldn't capture all that i wanted.

The second shot is with the 11-24 f4L, and is also at 16mm. While i love the 11-24L lens, the size of the lens is a pain. The bulbous lens design and the size of the SW150 ND Grad filters, it was almost impossible to clean the spray off the lens and filters. A smaller (regular flat lens surface and smaller filters would have been much easier to clean. I only had 5 to 8 minutes of the having the light, the sun where i wanted it, waiting for people to walk out of the frame, AND wipe away the spray on the lens and the filter. Bulbous lenses are a bxxch to clean, and the huge Lee filters are just as difficult to wipe.

I actually took more shots from the same location as the second shot and shot at 15 mm as well to get my kids in the shots, and could see how far off to the side I could have them, before distortion would be a factor having people in the shots. I loved being able to go wider - the extra mm helped to get those shots.

WIth the 11-24, I can see that with the Lee adaptor it will vignette between 13-14mm, so I know I have to zoom out to around 14mm to play it safe. I just want to make sure I can do the same with the 14-35L and 15-35L that have in camera corrections.

The other question is which has the better sunstars with the 14-35 and 15-35?? WIth the two shots i posted, for both the 16-35 F4L and the 11-24, i had to stop down to F16 - which softens things up with diffraction to get the sunstar i wanted. I find the 16-35L to be much better stopping down to F16 than the 11-24 does. the 16-35 f4L was also steller with the sunstars. Wondering if there is any difference between the 14-35 and 15-35?

Ideally, i'd like to get the widest lens as i can - but in the past I had the TSE 17, TSE 24, 16-35L, 11-24L, 24-70L, 85L, and 70-200L. Going forward, i don't want as many overlapping lens. Prefer to go with the EF 70-200 f2.8L III, RF 24-70L, RF 85L and one of 14-35L or 15-35L. Maybe sometime down the line, I may add a TSE back in the mix, but I'm trying to go with a more limited set of lens going forward.

I shot the 15-35 as a rental for a week and I've been shooting with the 14-35 for a few days. To me the 15-35 wins for sunstars as they seem to develop at wider apertures and therefore are more prominent at comparable apertures. I don't have an apples to apples comparison, but the first shot below is the 15-35 at f/14 and the second and third the 14-35 at f/18. For the 14-35 images I clicked through the aperture settings until I found the size of sunstar I wanted and in this image and a few others this has come at f/16 and f/18 where the effect of diffraction is significant. However, as I have put in other posts, the 15-35 is just too large and heavy for me to want to carry it on travels whereas this 14-35 is perfect.

Sorry if that wasn't obvious from the screen shots, the film strip is at the bottom showing the thumbnails. The 200% crops are from the upper left corner of the frame. If you look at the center of the frame it's a closer contest, advantage still 14-35. At f8, the advantage is still 14-35 albeit minimal.

well looks like the 14-35L has finally arrived in Canada and I've been told that I should be on the initial shipping list. Still agonizing over the 14-35L and the 15-35L.

So far pro/cons of each:
RF 14-35L
-Huge size advantage
-extra mm
-From Jesse's tests there looks to be a lot of vignetting from 14mm to 17mm (real world shooting concern is effect on corrections on details in snow/ice foregrounds like in the photos below
-Stan's photos seem to suggest that the 14-35L is an upgrade on the 11-24L in terms of detail (unsure about vignetting)
-Unsure how much effort will be required for corrections in LR
-Sunstar in Ketang's example seemed to be about the same as the 11-24L, and not as good as the 15-35L (although it wasn't an apples to apple comparison)

15-35L
-looks to have less vignetting in the examples provided by Jesse
-Sunstars in Ketang's photos looked stellar - as good, or better than what I was getting on the 16-35 F4L
-F2.8 would be more useful for night astro photography
-Negative is that it is a BIG lens and 1mm less wide

Question for Jesse, Stan and Ketang, from your impression using the lens, how effective do you think the vignetting and in-camera/software corrections would be for handling snow/ice foregrounds like the ones in the sample pictures I posted. Would detail in the corners be lost

Would the snow in the corners still be darker/grayer?

Decisions, decisions!!! I hope you guys keep posting more examples and if you can, it would be great to get some apples to apples comparison of what sunstars look like!

I would not be so sure that the 15-35 would be a better astro lens. It has ~4 stops of vignetting when it is wide open like the 16-35 f/2.8L III before it, making it a pretty poor choice. Canon actually does not make any lenses that are considered very good for astro. You'd be better off buying the 14-35 f/4L IS USM and a Rokinon / Samyang lens to supplement.

There is not exactly a lot of fine detail in the corners there. I believe that you'd be satisfied by either lens when you are shooting stopped down. The snow should not be darker or grayer, when corrected for distortion there is not very much vignette left on the RF 14-35 f/4L.

I would love to get out and shoot more, but unfortunately, most of Northern California is on fire, making it a bit difficult. Last night I went out to the coast to try and get a better idea of the lens performance, but was fogged out.

Thanks Jesse!
I. Hope things get better for you guys! We’ve had a lot more wildfires the past few years. There were a number of days where I could smell the smoke inside the house, and there were air quality warnings, but not to the same extent as it appears you have.

Ordinarily by this time of the year, wildfires are under more control - is this year worse for you guys?? every year we see reports of wildfires in California, but it sounds like it’s worse this year.
