I often shoot from a scene from f2.8 to the highest f stop available, and I'd guess I have as many times when f22 was the best image as I have when f 2.8 was the best image. Simply put, if you limit yourself to what you believe, you're going to miss out every time what you believe is a subset of what is real. The best image is not always the sharpest image. Sometimes it's the one with the most DoF. Something that in this narrow depth of field crazy forum, often gets completely overlooked.

When discussing lenses people always want to know how good the lens is wide open. I've never actually heard a person ask how good the lens is at f22 or f32. I'd say that represents a pretty clear bias.

Yesterday I was at the Lineman's Rodeo finishing off a roll of iso 800 on the Canon A-1 with the FD 70~210 zoom.
So most shots were necessarily around f/16 and 1/250th or so. There were no qualms about those kind of f/ in the old days.

(Reposted) Here is the K-01 with the 18~55 kit lens at 18mm
at f/8:

at f/22

The diffraction is certainly apparent in a full screen side-by side

Yep.
f/22 is there for the same reason f/2.0 is there - they both have a purpose.

As the actor Michael Caine once said " you eventually get to the point where you have to say f*ck it, I don't care! and just get the job done"
I cannot believe a quote from Michael Caine is being used to such effect.

The problem with most amateur togs is that they are concerned about all the technicalities of a shot but never the photo. Sharpness, noise, dynamic range and other bullcrap. A good image is a good image even if it's not sharp or noisy.

f/22 or f/32 can get you some depth of field when required with a long lens.
Using film cameras f/22 or f/32 can be handy when you don't have a ND filter.
I just took some flowing water shots this morning with the Pentax-M 120mm f2.8, which closes to f32 like a lot of the M or K telephotos. I tried f32 first, just a bit too bright at the shutter speed I wanted to use. I wanted one stop darker. A polarizer would have been enough:



This was with the Hoya ND400 filter, which gives me a lot of flexibility for shutter speed, but I had to shoot at f4. The interesting thing is that the purple fringing is not a problem at f32. The Hoya has a color cast too, not that hard to fix.

A couple of the Pentax Super telephotos have f45, it's for DOF.
