Hi Klaus
In your review of the Pentax DA-L 35mm f2.4 under the 'Bokeh' section, you wrote: "The Pentax lens does a rather average job here which is typical for lenses with aspherical elements. Out-of-focus highlights can show an outlining effect and aperture shape gets already visible at f/3.2 - the latter aspect is an effect of the non-circular aperture blades."
Can you clarify as to whether the lens has straight aperture blades, or curved aperture blades (as found in the DA*55 and D-FA 100)? I'm assuming "non-circular aperture blades" was a typo, and you instead meant to refer to "curved aperture blades" and/or a "circular aperture". Thanks

non-circular aperture blades = straight blades
