Why use f11 or f16?

Isn't f4 or f5.6 is where the lens is at it's sharpest?
When I need the depth of field I would use the smallest stop without worrying about diffraction.

If you wait until every condition and parameter is perfect,
you'll never get a picture.

Some good lenses actually are best a full aperture.

Why not f/32 or f/45?

Don't know the movie you mention but I once read an article titled "f/16 and Be There L-o-n-g-e-r"

It depends on what you are photographing, your vision for the final image, the conditions in which are shooting, the limitations of your camera and your technical abilities.

"f/8 and be there" assumes you couldn't afford better equipment.
No, Weegie said it to point out that f8 is the sweet spot for depth of field and image quality allowing him to simply point his big Speed Graphic without worrying about focus and minimizing metering decisions by using his vast experience with sunny 16 rule. Remember he was shooting with “manual everything” gear and wasn’t shooting artsy shots - he was shooting tabloid news photos.

Here we go again with Diffraction Overreaction. Diffraction may have been an issue in film days but that is a bygone era.
Everyone has access to post processing where the Dehaze and Clarity adjustments can completely ameliorate diffraction. F 16 is my favorite aperture for the reason that it balances sharpness with depth of field and in tandem with higher ISOs can take your image capturing to a higher level. That is, images other photographers miss because they haven't updated their thinking since film daze!

Start your ordinates at zero and you will see the drop off isn’t so dramatic. You might try overlaying DOF.
Noted photographer Bryan Peterson advocated f22 for most landscape images.

I took a quick look at diffraction and its effects on sharpness. https://www.uglyhedgehog.com/t-641034-5.html#11121069
The results showed that between f/5.6 and f/16 there was not much difference. Beyond f/16 the sharpness started to fall off (increased edge width in the graph below). This was done quickly and I plan to redo it with more data so I can put error bars on the points. When I get a round tooit.
This is a measurement using one camera (D800e, 36MPx) and one lens (105 f/2.8 Micro). Results may vary, but this particular lens appears to be sharpest between f/5.6 and f/16. Variations may be statistical and if I get to extend the study in my copious free time I may be able to refine the conclusion.

Also underscores what I was saying about Diffraction Overreaction above.
Some of the very good photographers on this forum are stuck in the minutiae of photography from days gone by. Wake up. It's the 21st century.

Some of my cameras have non interchangeable lenses and I can't buy any lenses with f/45 for any of my cameras. But I do know Bob can because he has the right type of cameras for that.
