I almost agree with Kent. In some situations, such as very large prints, enlargements of small sections of the original image and pixel peeping at 100%, yes you can notice some softening due to diffraction. However, at the size posted, the images were unlikely to *look* unsharp due to diffraction. I think the dispute is over the phrase "less noticeable". I suggest, and I believe my test examples defend the suggestion, if you post a reasonable sized image to the forum, it hasn't been heavily cropped and enlarged, and it has been properly sharpened in PP, it's unlikely anyone will notice ANY diffraction softening for typical images, ... unless they read the EXIF data, then they may notice it even if it isn't there.
Why belabor the diffraction issue?
- Because using small apertures is a reasonable option. Do not fear to use them. They are there for a reason, but understand the minor limitations.
- When searching for the cause of inadequate sharpness, know when to blame diffraction and when to ignore it as a possible cause.
- Even on a large print where diffraction can slightly soften the image, the degree of softening is usually unimportant and can be out-weighed by the advantage of greater DOF.
