Pentax DA HD Limited Lenses Now Shipping
B&H Photo has the Pentax DA HD Limited lenses in stock as I write this.
Given the relatively slow lens speeds, my expectation is that the Pentax HD lenses were designed to deliver very high performance (by restricting the aperture brightness, many compromises can be avoided). I’ll be covering all of them with that question in mind.
The equivalent focal lengths in full-frame field of view terms are 22mm, 33mm, 52mm, 60mm, 105mm.
