A couple of weeks ago we were discussing the effects of small apertures on 
digital image quality, compared with the same for film.

The message was that smaller than maybe f/8, the effect was not good.

Two days ago I was using my E-3 as an exposure meter for a 6x17 film 
camera. Probably not a good thing to do, and I should know in a couple of 
weeks or so after I send a few rolls off, then get them back from processing.

However. I had the E-3 at f/22 for the film camera, and forgot (for a few 
exposures) to return the f stop setting to my customary f/8.

Having looked at these f/22 images on my computer, there is no doubt in my 
mind that the images are significantly softer. I took all the digital photos 
that 
day hand held, and took about the same degree of care over all of them.
