Review Summary

Rated 5 out of 5

Fantastic lens.

I rate the lens outstanding. I rate the delivery a ?1?. The ?1? is not Adorama?s fault. I blame UPS. It was delivered out of the Secaucus, NJ UPS facility and that place is a dump. The box the lens came in was slightly crushed as was the main box Adorama shipped it in. I doubt seriously that Adorama would ever ship a box that was crushed to begin with. I used to drive OTR trucking and that UPS center is a nightmare. Thankfully, the lens is pristine and works beautifully. It?s well made and finished. If Adorama could do one thing, that would be to use another shipper.

A True Pentax Limited!

This lens is opticaly excellent. It's built like a tank. The focal length is a great for street photography. The color rendition is outstanding. The only drawback is the variable aperture.

A great lens which deserves it's "Limited" title

A great lens which deserves it's "Limited" title. While it is an apsc lens, it is capable of working on the full frame K-1. The metal build and weather sealing give this lens the quality expected of a Limited lens. This lens lives on my K3, and sees plenty of use on my K-1 as well.

Great niche lens

Quite the odd range, 20-40mm, and not the fastest lens in the universe, but for street photography it is quickly becoming my go-to lens. On the APS-C K-3 (which is what I use), 20mm=30mm full frame. This is a great length for street and events. The lens is very sharp, has beautiful color rendition, and very minor distortion/fringing (which is readily dealt with in Lightroom). It's also weather resistant, and I'm happy to now be able to go out in the rain and shoot. I put the lens on a Pz-1p film camera and did not notice any corner vignetting, so don't let the fact that it is a DA lens concern you too much...I'll have to run a roll of film through it to see what actual photos look like though.

It's a winner

This is a great lens for landscapes! Obviously it's not super wide at 20mm but it does perform within its zoom range. It's very sharp, and extremely well built. Images with this lens, shot on a K3, uprez very very well. I think it has to do with its color rendering and micro contrast. A great deal has been said about the sharp mages from the sigma 18 35, but for landscape where you are likely to be stopped down I believe this to be the better lens ..

good but overpriced

Bought this lens to replace my kit 18-55 WR lens when I'm hiking and other cases when I can carry only 1 lens and might need WR. The 20-40 is actually bigger in size than the 18-55 but not by much. I am mostly using it for landscapes. It has better contrast and colors than the 18-55 and might be sharper at the corners. I found I don't miss the extra range of 18-55. Overall, even if it produces better images the difference is not that big so I would not recommend this lens at the current price.

Featuring the newest HD coating, round iris diaphragm, and weather-resistant construction, this single lens enables shooting from the wide angle to medium telephoto ranges.

This lens covers the range from wide angle to medium telephoto and provides a natural perspective that is close to the view of human eye. This 2X lens is suitable for day-to-day use that supports a wide range of photography, including landscapes and portraits. As would be expected from the newest lens, it features sharp, detailed imaging with a soft rendering effect. This lens has a weather-resistant construction, and it can be used to configure the ideal photography system by combining with dust-resistant, weather-resistant PENTAX digital SLR cameras.

HD coating
This coating reduces the reflection rate up to 50% more than the conventional coating (compared to PENTAX multicoating) for reduced flare and ghosting even under backlighting and other adverse conditions where strong point light sources can enter the lens.

Round iris diaphragm
A 9-blade, round iris diaphragm is used. This enables natural reproduction of illumination and other scenes and softer out-of-focus (bokeh) effects for making the subject stand out more prominently from the background.

Internal lens motor AF
For the first time, the Limited series now uses a DC motor inside the lens barrel for providing a focusing mechanism. Compared to body AF, this focusing mechanism provides a quieter drive sound and smoother AF operation.

ED (Extra-low Dispersion) Glass/Anomalous Dispersion Glass
ED (Extra-low Dispersion) Glass and Anomalous Dispersion Glass are used to minimize color blurring over the entire zoom range and even at the edges of the image for providing superior resolution.

Weather-resistant construction
Photography when exposed to water or sudden rainfalls A weather-resistant construction is used for overcoming adverse conditions. The focus ring and zoom ring also have a weather-resistant design for preventing the entry of water.

Machined Aluminum Material
The lens barrel, cap, and hood use a machined aluminum material. You will feel the presence and elegance of the Limited series whenever you look at or touch this lens.
