Pentax DA 12-24mm f/4 ED AL (IF) Overview

The Pentax SMCP-DA 12-24mm f/4 ED AL lens was developed for exclusive use with Pentax digital SLR cameras, and is a compact, lightweight two-times zoom lens that offers an ultra-wide-angle perspective equivalent to 18.5mm to 37mm in the 35mm format.

This design also contributes to a drastic reduction in size, weight and production cost, compared to 35mm-format counterparts with similar specifications.

Not suitable for 35mm film SLR cameras.

I am looking for an ultra wide lens for a Pentax K5 ( and likely a K3 in near future ).I have basically narrowed down my selection to the Pentax 12-24 f4 and the Sigma 10-20 F 3.5.Uses: landscaping.Which would you say would be the better choice? There is not much of a price difference.Is there another brand of lens that I have inadvertently omitted from my choice list?Richard

Is this lens weatherproofed?

No the lens not weatherproofed. I have used it in light rain with a small towel without any problems.

Will this work with the K-1 full frame?
Asked by: Gerald
I tried it yesterday - I would say it is usable at 18 mm and above in full frame mode. Crop mode obviously always works...

will this lens accept lee filter kit?
Asked by: Anonymous
As the Pentax SMCP-DA 12-24mm f/4 ED AL Autofocus Lens uses 77mm filter threads, the LEE Filters Adapter Ring - 77mm - for Wide Angle Lenses, B&H # LEARWA77, would be my recommendation to attach the LEE Filters Foundation Kit to the above lens.
