f-stop sweet-spot

I have read a few comments on here recently about the 'sweet-spot' usually being somewhere in the middle of the f-stop range (I appreciate the actual figure may vary according to which particular lens is in question).

I shoot mainly landscapes, and normally use something like f16 or f22 (i.e. the smallest available) to try and maximise depth of field.

Am I missing a trick here - would I get sharper results using the 'sweet-spot', or am I okay?

Ta

Phil.

It's all about Diffraction Sharpness Phil. This will help - immensely.

In theory the medium apertures bring out the best in a lens but whether the difference is visible to the eye is debatable. If you're using a wide-angle lens it generally isn't necessary to use a very small aperture, f11 should do the job.

Thanks Mike - some bedtime reading!, and thanks Michael - I will try some this weekend and see what like the results are.
