Key Features
- K Mount Lens/Full-Frame Format
- Aperture Range: f/2.8 to f/22
- Three Aspherical & Three ED Elements
- Anomalous Dispersion Aspherical Element
A fast, standard zoom featuring a sophisticated optical design, the HD Pentax-D FA 24-70mm f/2.8ED SDM WR Lens from Pentax is designed for use on full-frame K mount DSLRs, as well as APS-C cameras where it provides a 36-105mm equivalent focal length range. The constant f/2.8 maximum aperture offers consistent performance throughout the zoom range and pairs with a rounded nine-blade diaphragm to produce smooth shallow depth of field imagery. The lens' design incorporates a trio of extra-low dispersion elements, three aspherical elements, and one anomalous dispersion aspherical element to control a variety of aberrations and distortions in order to produce well-corrected images with notable sharpness and even illumination. An HD coating has also been applied to further benefit working in difficult lighting conditions by suppressing lens flare and ghosting for increased contrast and color neutrality.

Could I use this lens on my K1000? i know it's an old manual focus film camera but I think this zoom would be nice for it lol
You could but there is no aperture on the lens, so you will not be able to control exposure.

question
what is this lens mount? kaf3? kaf4?
It is KAF3. KAF4 is the new mount that the new 55-300 PLM is the only example I'm aware of.

question
Is this lens compatible with the Pentax K20 D?
I believe the K20D uses a mechanical focus linkage while this lens uses electric focusing only, so the automatic focus would not work. The lens is also quite large since it is a full-frame and the K20D does not need a lens this large.

question
Is this an internal zoom design or does the lens extend when zoomed towards long end? Thank you.
Sorry I didn't respond sooner, but the lense does extend out away from you

question
Is one of the 5 weather seals at the lens mount so as to keep weather out of the camera?
Yes, as with all Pentax WR lens, there is a neoprene like ring that contacts the camera body mount for proper sealing of moisture and dust.
