Review on PENTAX Limited Lens - HD PENTAX-DA21mmF3.2AL Limited Silver K Mount APS-C Size - Thin Wide-Angle Single Focus Lens (21420) by Iseul Chang ᠌

As a cropped width, it is significantly better than a 12-24 zoom both in terms of design and quality of workmanship. However, after the release of 15mm Limited, I would certainly take a tag. Got pros: Magnificent constructive, as well as at all glasses of this series. Good detail, decent constant aperture, drawing. Very nice bokeh. Its cons: Distortion, what is there. Chromatite is also decent, but quietly removed in the converter. The original design of the lens hood, which does not allow the use of filters at the same time. The lens cap is of course major, with velvet, but it is not put on a screwed-on polarizer.
