Pentax 28-105mm f/3.5-5.6 overview

  • 1Description

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.

Pentax 28-105mm f/3.5-5.6 reviews

HD PENTAX-D FA 28-105mm f/3.5-5.6 ED DC WR Lens is rated 4.8 out of 5 by 22.
Rated 5 out of 5 by from It's everything everyone says it is. Whether you're using it on a current APS-C Pentax or the new full frame K-1, you'll find the Pentax 28-105 to be very satisfying across the range, corner to corner and dead center. It's surely one of the better 28-105 lenses that have been produced over the years and miles ahead compared to most kit lenses. It performs perfectly on my K-30, but I purchased it because I'm going in the direction of the K-1 at some point. I can't compare it to other Pentax zooms 'cause I don't own any. But I can compare it to my Tamron 17-50 f/2.8, and it compares favorably when both are shot at f/4 - f/8.

Rated 5 out of 5 by from Sharp and Solid Sharp all across the image on my K3 (APS-C). Very solid construction. A pleasure to use. Designed for full frame so I was expecting it to be a big lens so I was pleasantly surprised by the reasonably small size and light weight when I got it.

Rated 5 out of 5 by from it is more than a kit i was between dfa 24-70 and dfa 28-105. i tried both but finaly i went with dfa 28-105 for its versatill and of sure for the price. the lens is sharp even at 28 mm and very sharp at 70 mm. it is my walk around lens and for this reason it is on the camera all most the time.

Rated 5 out of 5 by from Quality Lens This lens offers a nice zoom range and high quality optics. This lens compares with my Canon 24-105mm lens that I have been using for the past 10 years for zoom coverage. The Pentax lens in my opinion is crisper than my Canon lens. I have not found any negatives with this lens. It is smaller and lighter than the Canon and when mated to the Pentax K-1 Body is a very nice handling combination. There are some subtle design features influenced by working photographers such as the removable section of the lens hood to make available the rotation of a polarize filter. Large deeply textured surfaces for holding and adjusting the zoom and manual focus. Also the body lens cover is locked in place and requires the lens release button to be actuated for its removal. Image quality in combination with the Pentax K-1 body is outstanding. I have found no artifacts with images taken with this combination of lens and body which I have printed at 24 X 36 and have contemplated going to crop outs from the equivalent of an 100 by 66.6 image as I see no degradation in image quality on my monitor. This lens is superb for my overall photography work, light weight, good zoom range and quality optics. It fills the bill without having to carry around addition lenses.

Rated 4 out of 5 by from Good Choice It arrived intact and seems to perform well with the K1. The zoom is a little stiff, but that's better than too loose. I don't notice any drop off in the corners and it focuses quickly. This will be a work horse for me.

Rated 4 out of 5 by from Another solid Pentax lens As others have said, this is a great walk-around lens to have on your camera. It's very easy to use, easy to carry and focuses quickly and quietly. When it comes to sharpness, however, the images it produces are a little soft; that's is the only issue keeping me from giving this 5 stars.

Rated 4 out of 5 by from Good travel lens! I wanted a digital zoom lens for my new K-1, having only older FA limited lenses and not wanting to shell out almost the same amount as I did on the camera. It focuses very quiet and fast, it takes good pictures outdoors, as stated buy another review, get the DA F 24-70 f2.8 if you plan to do any picture taking indoors without a flash. I am happy with my purchase and would recommend it to anyone that wants a good travel lens!

Rated 5 out of 5 by from much better than expected I selected this lens rather than the new 2470mm primarily for the longer zoom range, not the lower price. IQ is much better than I had expected. It would have been nice to have a slightly longer range, say 24135, but not at the cost of losing the image quality.
