Originally posted by TwoUptons My understanding from reading the initial material is that they emphasized edge-to-edge sharpness at smaller apertures and longer distances.
To me that suggests that in addition to making the bokeh look good for those close-ups, they probably have played some games with the field curvature -- it is probably very different at infinity than at close distances.
I think that's a pretty desirable trade. Not many people will likely use this lens for macro copy work

I have a Zeiss ZK 28mm f2 that also has those characteristics by design. It makes it a very interesting lens - f2-f4 used for soft, dreamy effects and f5.6 and above very sharp. It is field of curvature that is used for the effects and transitions in the Zeiss.
The Zeiss 28/2 is known as a 'Hollywood' lens and is very highly rated by some very experienced and exacting reviewers. It is an excellent lens.
If the Pentax D FA 21/2.4 Limited lens has these characteristics it will be very highly sought after by people who know what you can produce with such lenses. Such characteristics basically gives you two lenses in one.
If the internet's favourite 'pop' reviewers don't understand or appreciate such a lens it is more a statement of their skills, technical understanding and preconceived bias, than the ability of the lens to perform.
I am looking forward to the well informed reviews of this new Limited lens, and then if everything is good, purchasing the lens.
