The silver HD Pentax DA 21mm f/3.2 AL Limited Lens from Pentax is a compact pancake-style prime wide-angle lens providing a 35mm-equivalent focal length of 31.5mm. The broad 68° angle of view is well-suited to all-around shooting for both interior and exterior locations. A high-grade multi-layer HD coating has been applied to lens elements to help minimize flare and ghosting for enhanced contrast, clarity, and color fidelity and a seven-blade diaphragm contributes to an aesthetic out-of-focus quality to benefit shallow depth of field imagery. Additionally, an SP Protect coating has also been applied to the front lens element to effectively protect it from dirt, oil, and finger prints.

The compact form-factor of this lens integrates Pentax's Quick-Shift Focus System, which allows manual focus control over the lens at any time, even in AF mode, for precise handling over the focal plane.

Q: 1. One of the reviews mentions they didn't like the manual aperture but the picture shows an A setting on the aperture ring which I assume means auto. Thus I would expect that the aperture could be controlled with the control dial either directly or adjusting the shutter speed. Can someone provide the answer?

A: When the lens aperture is set to 'A' the aperture is controlled by the camera and auto aperture control modes, or through the camera controls in manual aperture control modes.This is the same on all Pentax 645 lenses with the 'A' in the lens name, and you can verify by setting if the aperture ring has an 'A' setting.The aperture ring merely gives you the option to go full legacy manual mode, which is sometimes handy, but for the most part I leave mine on 'A' and even if I take a picture in manual exposure, I set the aperture with the camera wheel.
