Pentax D FA 28-105mm f/3.5-5.6 ED DC WR Overview

Versatile, relatively compact, and compatible with full-frame K-mount DSLRs, the HD PENTAX-D FA 28-105mm f/3.5-5.6 ED DC WR Lens from Pentax will be a perfect pairing for many shooters thanks to its wide-angle to medium telephoto range. The lens also features an f/3.5-5.6 variable aperture to help keep size down while also utilizing ED glass elements to reduce aberrations. The lens sports both Super Protect and HD multi-layer coatings in order to protect against accidental damage and reduce flaring and ghosting.

Focusing is fast and quiet thanks to the integration of a Supersonic Direct-Drive Motor and the lens has a Quick-Shift feature for fast switching between auto and manual focusing. The lens also focuses as close as 1.64' and it has a 9-blade rounded aperture diaphragm for smooth out-of-focus elements. Additionally, it is dust- and water-resistant with eight seals to protect from intrusion.

Covering wide-angle to medium telephoto perspectives, this versatile 28-105mm zoom offers a convenient option for full-frame K-mount Pentax DSLRs and is also compatible with APS-C models, where it will provide a 43-161mm equivalent focal length range.
Variable f/3.5-5.6 maximum aperture ensures a compact size while offering a wide range of versatile focal lengths.
ED glass elements are featured in the lens design and help to control chromatic aberrations and reduce color fringing for increased clarity and color fidelity.
The High Definition (HD) multi-layer coating is utilized to reduce reflections, flare, and ghosting for improved contrast and color in more trying lighting conditions.
Super Protect coating will help keep the optics safe in the event of accidental impact or if it comes in contact with water or dust.
Supersonic Direct-Drive Motor (SDM) ensures fast, quiet, and smoother autofocus operation.
A rounded nine-blade diaphragm contributes to a pleasing bokeh quality when employing shallow depth of field techniques. It is completely rounded between f/3.5-6.3 when at 28mm and between f/5.6-10 when at 105mm.
A weather-resistant design features eight seals which better permit working in inclement conditions.
Includes PH-RBS62 lens hood to limit flare from light sources.
Optional S-80-120 Soft Lens Case is available to protect lens during transport or storage.

Does this lens work with the old film K 1000 camera?
Asked by: MICHAEL
The Pentax HD PENTAX-D FA 28-105mm f/3.5-5.6 ED DC WR Lens will fit on to the old Pentax K1000 but you will have no control over the aperture and it will be set to the smallest.

Will this lens work for a FF Film Pentax Camera MZ-S, With AF, Last Film Camera 2001, Pentax LX previous Model ?
Asked by: Alfredo
A yes with MZS. I tried the lens on my MZS and both components functioned as expected and the mechanical & electrical connections were fine. CaveatS: the aperture controls for the body to lens rely on internal control-no external f-stop ring on lens. So, you may want to practice with the MZS & lens because digital bodies are not exactly the same as with MZS, imo. I like the lens and use it on my K3ii & MZS, but no K1 yet waiting for 3rd version :)

In manual focus mode and with taking pics at night how do you know when you have reached infinity with the focus ring, it just keeps going around?
Asked by: Wendy
Unfortunately, there are no indicators on Pentax cameras when you have reached infinity (tested with K70, K3 Mk III, and K1 Mk II). The lens' focus ring does produce a minimal "bump" as feedback when you are at infinity, although it might be a little hard to notice if you're not paying attention.
