Re: DA14mm f/2.8 quality (was: Pentax 50mm News)

possibly. i usually need f11 for adequate DOF in my landscapes. OTOH, the DA 
16-45 is consistently sharper in my use and i use the same range of 
apertures most of the time.

Interesting. At f/8, the DA14mm's aperture is less than 2mm in
diameter where the FA16-45 is at 2mm or greater. Perhaps you're
seeing the onset of diffraction, reducing the resolution. How do
they compare at f/5.6?
I normally set aperture between f/4 and f/5.6 with the 14mm.
