5DSR, 11-24mm @ 11mm, f8, HDR, ISO 100, panorama from 4 portrait shots, cropped to ~15K X 8.5K at full res. Screenshot of hires version for details. Still ended up with a bit of a halo around the tree on the left, but overall was a decent rendition of the scene at sunrise from Grandview Overlook, GC, Aug 1st 2017.

Wondering if anybody tried this one https://www.bhphotovideo.com/c/product/549036-REG/Kodak_8645541_3_x_3_Neutral.html ?

Theoretically it shouldn't impact CDAF/DPAF focusing during the day...

That's what I use with my 11-24L, cut to size.

The link page shows a pair of sample photos that got me wondering how much this filter affects IQ. Any thoughts?

@ tpatana I know the feeling. Obviously, watch that piece of glass that sticks out! I don't qualify to be giving advice.

I find that objects that have a known and easily identifiable shape in the extreme edges of photos will not present well. Objects like rocks could be any shape so they do better. Being so wide, everyone advises that there needs to be something interesting in the foreground and since there tends to be a lot of sky it helps if that contains clouds etc.

I sometimes crop my wide shots more than 16:9 to look like a panorama and get rid of some earth and sky. Like you, I'd like to hear other's comments and better still see fantastic photos. Here is one where I thought that 11 worked but maybe not. ;) Because the lens is good some after the fact cropping is possible.

Good to know. How do you store gels? Are they easy to scratch?

The first review @ B&H is impressive: "This stuff serves no real purpose. I am a fanatic about protecting my lenses. These filters are flimsy and wont protect against anything but light." LOL

Just received mine :) Going on trip next week, hoping to get some scenery shots. I've never had anything this wide before (I have Canon 15mm 2.8 FE (which I'm planning to sell)), but it's different.

So any beginner mistakes I should avoid doing? Good tips?

Btw., first impression on receiving was totally "holy sh** it's huge!".

Congrats! As a beginner myself the only tip I can give - don't always shoot @ 11mm, it's just too wide :)

I store the cut one in a little DIY sleeve made from a manilla file folder, and the remainder of the original square (from which I can cut more filters) in the origanal packaging. The gel seems pretty tough, I haven't scratched my first cutout (not that I've tried or treated it roughly).

Magnifico!!!

As usual, click for larger. Thanks for looking!

I admire all of you who can afford the magnificent 11-24, but for me all I can muster is a refurb Sigma 12-24 MK2. I took the Sigma on a recent trip to Wales and thought I would share these shots just for a fun comparison. All were shot on a seasoned Canon 6D and run through DxO OpticsPro 10 and Elements 12. DxO does a fantastic job of auto-correcting the obvious faults.
The amusing thing that I find with the Sigma 12-24mm mk II lens (I used to own the mk1, back in the day). is that wide open the corners are very poor optically when compared to other newer lens offering. The Sigma 12-24mm f4 and the mighty Canon 11-24 F4 L come to mind. However...most landscape photographers are going to stop down to f8-f11 to maximise Depth of Field. At these apertures...there is little diffference between these lenses from a sharpness point of view. A comparision of the edges between these lenses when stopped down whos very similar performance.
The only real benefit of the newer lenses are their wide open performce. Ironically, which no one is going to want to use in the context. It's not like a 24-70 f2.8 that one would want and need to shoot wide open all of the time.
So yes for landscape work, the Sigma 12-24 mkII is a bargain. It's light on the wallet S/H and it's light in the camera bag too.
It also explains why these lenses rearely appear on the used market. Firstly Sigma didn't sell that many and 2ndly, those who have them know how good they are and thirdly, no one is going to sell one for peanuts on the used market.
There's a few primes that offer similar angles of view and in some cases an even wider ang;e of view: the illustrious Samyang 10mm f3.5 XP comes ot mind. Optically, it's equal to the Canon 11-24mm L but offers manual focus only, A static angle of view, but an even wider perspective.
