Pentax 21mm f/3.2 Limited SMC P-DA

I enjoyed using the 21mm ƒ/3.2 as a walk-around lens on a K100 Super: it's small enough to be extremely portable, fast enough to be very versatile, and tough enough to last.

This is one of the lenses that has made a lot of pros keep their Pentax gear, as it is superbly made, sharp as a needle, and very small. Can't fault it in any way!

This lens is the latest addition to my lineup. I purchased it to have a wide option for low light.

This is a beautiful lens. Everything about it is fantastic: it AFs like a charm, it's brilliantly sharp, the closest focusing distance lets you get up close and personal with your subject, its rendering of colour is great... My only problem with this...

Very good all around prime lens. A pleasure to carry and useful in many situations.

The fact this lens “huge centre sharpness at wide open” falls back really quickly towards the edges and corners, makes it my favourite artistic lens!

Because of the focal length, this lens is on my camera more than any other.
