For those interested in the EXIF, the cat was 11mm @ f5.6, the car was 14mm @ f20 deliberately for the starburst.
And for those that say the dof of an 11/14mm at f4 is 'massive' I beg to differ. Here are a couple of 100% crops from the cat picture @ f5.6. Clearly not even the entire cat is covered by the dof let alone the entire scene.

I've wondered about this in landscapes trying to have everything from a close object back, in focus. So, if you were focused at infinity how far would that feline have to be to appear in focus? Also, when not using a tripod it's hard to judge if infinity is actually in sharp focus.

Caution - objects may be closer than they appear. How close was the cat?
It really depends point of focus, particularly near MFD of 11". If your subject is at 12" the DOF is 9" to 20" at f5.6 or 7" to 43" at f/11 on my DOF calculator. If you move your subject out to 30", the DOF is 15" to infinity at f/5.6. At f/11 you can DOF is 12" to infinity as long as your point of focus is more than 18".

Nonsense.
Those figures all presuppose an 8" x 10" print viewed from 12", that is just not how we view images nowadays. For instance I have a 27" screen, if I view at 100% the image is scrollable at 5616/109, or 51" at a mere 22" viewing distance. As magnification goes up dof goes down so I have way less dof than your calculator estimates.

Nonsense.
Your figures presuppose a computer monitor, and that is just not how we view images nowadays. For instance, if I have an iPhone 6 that's a 4x2.25" image viewed from 14", so I have way more DoF than your reestimation of the original estimate estimates.
;D

Hope you had a nice time in France wile you were there.
I did have a nice time, although photography time was limited (I was there for a scientific conference).
Composition is challenging with the 11-24! There were a few shots where I used the 11-24L and also the TS-E 17L for the same scene, and often ended up preferring the TS-E image. Here's an example, the first with the TS-E 17 and the second with the 11-24 (I didn't actually process the latter, to remove flare etc.).

This is really beautiful! Looks like a winter wonderland. Beautifully composed.

Thanks. Here is a thought I've had. I seem to prefer the 11mm shots of landscape when they are cropped with less height, more like a panorama. It seems like that gives more emphasis to the fact that there is a very wide field of view and makes me imagine I'm scanning the view. And I guess often it removes the sometimes less interesting expanse of sky when it's not contributing much.

The 11-24L was ideal for the World War II Memorial. First shot is the view from the east side, second shot is looking straight up inslde the Atlantic triumphal arch.

As usual, click for larger. Thanks for looking!
