Description:
The HD Pentax-DA 20-40mm F2.8-4 Limited DC WR is the first zoom lens to join the Pentax lineup of ultra-compact "limited" lenses. This lens features a sleek all-metal barrel manufactured to very high standards.

This is also the first Limited series lens to feature silent DC autofocus as well as a weather-sealed design. Like the other HD Limited lenses, this lens features Pentax's latest lens coating promising less ghosting and flare.

As is standard for all premium Pentax lenses, this lens allows for full-time manual focus adjustments (Quick shift) and it is treated with Pentax's Super Protect coating to protect the front element from dust and scratches

The lens covers a wide-angle to normal focal length range, and is compatible with Pentax APS-C DSLRs. It will be available in both black and silver in December, 2013 for $999.

Pros: Sharp, Color, Weather Sealed, Light, Compact, Flare Resistance
Cons: Slow Autofocus, Price, Lens Cap
Sharpness: 9    Aberrations: 9    Bokeh: 10    Autofocus: 6    Handling: 10    Value: 8    New or Used: New    Camera Used: Pentax K-5IIs   

I bought this looking for an upgrade over the DA SMC 18-135 which I had used for a year or so and actually liked but I purchase a few of the limited series lens and was astounded at much better they rendered color and, in general, how much sharper they were over the 18-135. The HD 20-40 obviously doesn't have the zoom range and it isn't as useful in that regard but it renders colors so much better and is much sharper. I apparently got a good copy since I have found mine to be decently sharp wide open and very sharp when stopped down just a little more. The new HD coating works amazing well in tough, high contrast conditions. The autofocus motor is quiet. Not as quiet as SDM but much quieter than screw drive. It is a bit slow sometimes to lock onto a subject. Can be a tad frustrating at times.

Construction is top level and then lens feels good on the camera. Not too heavy but substantial enough. The weather sealing works very well. I was recently involved in a kayaking mishap where mine and my wife's tandem kayak sprung a leak in the middle of a bay in the Florida Keys. Eventually the kayak became too unstable to paddle and flipped. My wife saved the camera but it did get partially dunked in the bay. We were stranded out there for a couple hours till a boat came by and rescued us. The lens held up totally fine and the camera has of course okay as well. I was impressed! We of course were exhausted, dehydrated, and glad to be out of the water.

The price is steep for what it is but I wasn't willing to pay the equivalent to get the DA* 16-50 with potential SDM issues and the extra weight. I did find a good deal on this lens lurking Amazon but I do think the lens is a little too expensive for what it is. Maybe $799 for it brand new.

The lens cap is 62mm in size, the filter size is 55mm, and expensive! Don't lose it because it costs $40 to replace! It fits over the "lens hood" if you can call it a lens hood. My opinion is that flare is such a minimal problem with this lens that it could go without the lens hood the majority of the time.

I really enjoy using this lens. It stays on my camera 90% of the time.

Pros: Small, Light, Weather sealed, Quiet
Cons: Limited range
Sharpness: 10    Aberrations: 9    Bokeh: 8    Autofocus: 9    Handling: 10    Value: 8    New or Used: Used    Camera Used: Pentax K-5 IIs   

First of all I can't give an extensive review for this lens since I only had it a couple of weeks. Maybe after a few months I'll update this review to give you a better perspective on how I feel about this lens. I have lusted for this lens for quite a while now, but the thing that held me back was the price. Due to the limited range and due to some negative reviews I was hesitant to fork over that much money for it. A few weeks ago I was looking at the BH website and saw that this lens was selling for only $574 Used in 9+ condition !

This was about the lowest price I had yet to see for this lens new or used, so I got it. I figured I could always send it back within 31 days if I did not like it.

So, lately I have been testing this lens under as many real-life conditions as possible, hoping I would not have to send it back. Like I said, it's only been a few weeks if that many, but so far I'm pleasantly surprised. This lens is a marvel of engineering and so fits well with my K-5 IIs which is a marvel of it's own.

First I will describe the Aperture which some people have complained about being too slow. At 20mm you can open up to f2.8, at 25-30mm f3.5, at 35-40mm f4.0. Not bad considering that even some limited primes within those focal ranges are not much faster.

I compared the Sharpness of this lens against my 16-45mm f4 and 35mm Macro f2.8. The good thing about this lens is that it does not extend much from the body like my 16-45mm does. At 20mm it extends about 2/3 of an inch. at the other focal lengths it does not extend past 1/2 of an inch from the body. The distance scale on this lens is quite limited in that after 5 feet it goes straight to infinity with nothing in between, but that might have to do with lens design for zooms which I now little about

From what I can tell, this lens is a tad sharper than my 16-45mm across all focal lengths except maybe the 30mm focal length, why I don't know ? What this lens got going for it, is the way it renders the colors and the contrast. Not artsy, not over-saturated, but amazingly life-like. At 35mm, my 35mm f2.8 Macro is sharper across the length of the frame, but to tell you the truth, there is not much difference between all 3 lenses unless you really pixel-peep. If you really want sharp though, set the camera to ISO 80. Then you start moving into 3D territory...


Handling : Although this lens is supposed to be all metal, it is very light to the point where I think it's some kind of aluminum instead of real metal ? Nevertheless it is very well built, but I wish it had the heft of my other limited lenses just my opinion... The focusing is very well damped as well as the Zoom dial. So there is no problem there. One thing is the very fancy lens cap. I am so afraid that I might drop it and lose it (@$40) that I keep it in my left hand when shooting. This lens is light and well balanced enough for me to do that thankfully.

Autofocus is nearly silent and pretty quick. You really have to put your ears pretty close to the camera to hear it. This is perfect for places like museums, operas, churches, funerals, where the loud buzzing whirl of other lenses might become annoying. One thing I noticed is that the AF is faster and much more accurate if you limit the auto focusing points. I set my AF to Sel Mode and only use one focusing point, so far this has worked best for me.

Bokeh is reasonable mild/smooth a little better than on my 16-45mm, but not better than on my 35mm, or 77mm. I have not had the time to test this much so I can't say much about it.


Aberrations: What I like about this lens is this new Pentax Anti Flare coating. This really helps when shooting into the light, not just sun light, I'm talking about street lights and car lights and things like that. This lens does not fall apart like my Limited and other lenses do in those conditions. Another thing I noticed though is that this lens produces a little bit more CA under certain circumstances than my 16-45mm. It could be my copy, but I'm still investigating.


If you take all the features into consideration, not just pixel-peeping sharpness, this is a wonderful lens and a marvel of engineering. Time and experience will tell whether I will send it back, but so far so good.

Pros: Small size, build, styling, bokeh, image rendering, weather sealing
Cons: none
Sharpness: 10    Aberrations: 9    Bokeh: 10    Autofocus: 10    Handling: 10    Value: 9    New or Used: New    Camera Used: K3   

This lens is well worth having. Like another reviewer said, don't let some of the negative reviews scare you off. I found that none of the negative points are relevant. The f/4-2.5 aperture range is not a problem on a camera like the K3 with or K5 with their high ISO capability. The limited zoom range is not relevant either. The 20-40mm focal range covers the most-used normal-wide focal lengths on a crop sensor camera. All of the other lens makers, Canon, Nikon, Sigma, make zooms with similar restricted focal lengths and they sell just fine.

I tested the rendering capability against the FA-43 and SMC K 30mm (sire of the FA-31). The 20-40's rendering capability is equal to those two legendary lenses. The bokeh is very smooth resulting from the rounded aperture blades. The lens weight is deceivingly light. The size is small so it's not obtrusive nor obnoxious to carry. So many of the other zoom lenses in this range are as big as water bottles. I really like the tasteful styling with the Takumar-style zoom ring. All in all, it's a very excellent lens, capable of excellent results, on par with all of the Pentax Limited primes, and looks good to boot. Highly recommended!

Pros: Sharp, great contrast, thick lush color saturation
Cons: none
Sharpness: 10    Aberrations: 10    Bokeh: 10    Autofocus: 9    Handling: 10    Value: 10    New or Used: New    Camera Used: K3, K5IIs   

I LOVE this lens. The review(s) are wrong. They must have got a bad sample. This lens is as good as the primes it covers, namely the 21/31/35/40/43 LTD's. And most importantly it has that LTD magic photo dust sprinkled all over it, the shots are rich, lush and have that "artistic" something that we all crave. This lens (and the LTD's in general) make me want to photograph things just to see what they look like through it. This lens covers my 17-50 Tamron with WR and better IQ. I still use the 17-50 for weddings as a backup etc, but this 20-40 is my goto everything lens. With the 15 and 70, it is my travel/landscape foundation lens. I don't find the zoom range limiting at all. It's a very convenient fine tunable normal. If I need wide or tele, then I switch lenses. But for everything else it's perfect. Just buy one. At $695 USD it's a great deal.

Pros: IQ, general solidity and 'feel', construction quality, zoom smoothness, manual focus over-ride smoothness
Cons: None
Sharpness: 10    Aberrations: 9    Bokeh: 9    Autofocus: 9    Handling: 10    Value: 10    New or Used: New    Camera Used: Pentax K-5   

I bought this lens during a special offer period, and it has hardly been off my K-5 since. My previous standard zoom was the 16-45 which was itself a step up from the kit zoom, but the images from the 20-40 have something about them. Flare resistance is incredible. The supplied hood is a little small but with the HD coating, this is not an issue. Any necessary additional shading can be provided with the hand. Sharpness is very good indeed across the range, and at the sweet spot of around f8 it really is a cut above my other lenses.

The K-5/20-40 package is very compact, and the lens is just such a pleasure to use. The zoom is silky as is the manual focus fine adjustment, and the all-metal construction just feels so right. I also like the simplicity of the design: no knobs, switches, levers - just the zoom ring and the fine focus ring. Yes, the focus ring turns when the autofocus operates, but that's not an issue. The DC autofocus itself is almost silent and locks quickly, even on my veteran K-5. Strongly recommended.

Just a super lens. Sharpness, color, contrast are nothing less than outstanding on my copy. Covering the range of other limited primes (21, 31, 35, and 40), WR sealing, silent DC motor, smaller size (compared to the DA*16-50 and Sigma 18-35), flare resistance, makes this lens very good solution for me. I've had this lens for a week and have yet to take it off my K-3.

Pros: build quality, size for purpose, excellent optics, weather sealed
Cons: none, not wider or longer?
Sharpness: 10    Aberrations: 9    Bokeh: 9    Autofocus: 10    Handling: 10    Value: 10    New or Used: New    Camera Used: K3, K-x   

Odd focal range, variable from 2.8 to 4.0, DC motor, and weather sealed at a big price premium. Not your typical Pentax Limited lens. It's been awhile now and the prices of this lens has dropped in half for a new one. I took the plunge and now it's my walk around for what I shoot along with my Limited FA77 in my pocket. I can say that this is a great lens IF you need or want this focal range as it's not for everyone. I'm mainly a prime shooter. Never have really cared much for zooms simply because it makes me a lazy photographer. Only zoom in my kit is the 18-55 kit lens which doesn't ever get usage if at all.

Bokeh for this type of lens is great. I never expected my FA77 limited bokeh as you shouldn't either. Very sharp lens and perfect compliment on my K3 and my K-x. Right at the same size length as the 18-55 DAL kit lens, but just a little thicker. Actually about half an inch shorter than the 18-55 DAL if you use a hood lens on the 18-55. If you've been wanting this lens...get one. I got it for under $500 from Amazon, but it has now since gone up some. It's still a great deal for what you get. You won't regret it. I had a Limited 21 but sold it for this and have zero regrets.

Only real con is the focal length. You should already know if it's gonna work for you. Otherwise you won't be happy with it. I love this lens.

Pros: Light weight, small, water resistant, high image quality
Cons: Limited focal range

I brought the DA 20-40mm Limited in August 2015 (a year ago) second hand here on the Pentax Forum Marketplace. Like others looking at this lens I had seen the reviews where there were problems, and noted that there was clearly some significant sample variation with copies of this lens. After a number of test images with the seller, we were both satisfied that this lens was a sharp copy, with no de-centering or other noticeable image quality issues. Living in NZ as I do, it is also a lot harder, and more expensive to change lenses if it isn't right.

If buying this lens - do your homework and make sure you get a good, sharp, non-de-centered copy, then you will be happy.

I brought the DA 20-40mm Limited as my travel walk-around wide lens. In this regard, as you can't control the weather when travelling, for me a walk around travel lens has to be water resistant. I have previously owned the DA*16-50, and DA 18-55 WR for this purpose, both were sold after I purchased the DA 20-40mm. The DA*16-50 is a really good lens image quality and low light wise, but I found it a little too big and heavy for travel. The DA 18-55 is also a good lens, but does not come near to matching the DA 20-40mm Limited for image quality, and doesn't have as wide apertures. On the latest trip, on the boat that goes up to the Niagara Falls, a non-WR lens was not an option, the DA 20-40mm Limited did not disappoint.

I own and shoot a lot of prime lenses, including all the DA Limited primes (although I sold the DA 35 Macro a while back). Since purchasing the DA 20-40mm Limited I have barely used the 40mm, the 70mm is still very useful for portraits, and I still carry the 15mm for when I want wider than 20mm, but I am finding I am not using it much. I have kept the 21mm as it has a different colour signature to the DA 20-40mm and I still find I like the images the 21mm gives of water, but I am also not using it nearly as much as I used to.

I have recently completed a 3 week work / vacation trip to the USA, Canada and UK. I brought along the DA 20-40mm Limited, DA 55-300mm WR, the 15mm, 21mm, 70mm Limited Primes, and my Zeiss ZK 35/2 prime. 6 lenses. I found some days I used the Zeiss 35 extensively, but what I noted on this trip was how much I used the DA 20-40mm Limited, and how pleased I was with the images. I never used the 15mm, and I barely used the 21mm during this 3 week period.

The DA 20-40mm Limited, and DA 55-300mm WR makes for a good image quality, light, water resistant 2 lens travel kit. Usually when I am out walking and exploring I will take my K-3, the 2 zooms, and one additional prime. What I have found on the latest trip is that the DA 20-40mm is better than good enough, that I am seriously reconsidering even bringing the prime - maybe just the DA 70mm Limited for portraits.

Every lens is about a set of compromises, and how useful it is depends on what use you have brought it for.

I have some excellent prime lenses for image quality - Zeiss 28mm/2, Zeiss 35mm/2, Voigtlanders, DA Limited's, FA 50/2.8 Macro and a range of other Pentax prime lenses. I think I have a good basis for comparison.

The DA 20-40mm Limited image quality is right up with many of these lenses - certainly the DA Limited prime lenses, the colour signature is pleasing to my eye. The lens is water resistant, light weight, well built, and a pleasure to use.

My conclusion with the DA 20-40mm Limited is that it is a very good set of compromises, and that is provides a very useful wide angle lens, especially for travel, for Pentax APS-C cameras. After a year of use in New Zealand, Papua New Guinea, Solomon Islands, USA, Canada and the UK I can recommend a good copy of this lens to other Pentax users. I am very happy with my copy.

Pros: Great color and resolution.
Cons: Greens are punchy, some distortion
Sharpness: 10    Aberrations: 8    Bokeh: 8    Autofocus: 9    Handling: 10    Value: 10    New or Used: New    Camera Used: K-3   

I bought this recently for a trip to Europe as the zoom range is perfect for tight urban spaces and interiors, and still enough enough reach for other purposes. It did not let me down at all. Resolution is excellent, as are colors and contrast. If anything I find myself adjusting greens down a bit. I prefer that to the 21 Ltd that mutes greens--at least my copy does. Bokeh is OK, but I did not expect it to replace great primes in that regard. Most issues can be dealt with easily in LR. It is compact and lightweight, very easy to walk around with all day. Great lens for travel and general purposes. No regrets about this purchase at all.

Pros: Compactness; fantastic sharpness, color, and clarity
Cons: Nothing major
Sharpness: 10    Aberrations: 9    Bokeh: 9    Autofocus: 9    Handling: 10    Value: 10    New or Used: New    Camera Used: K-3   

I wanted a small-ish all-around weather-sealed lens to take with me on my recent cross-country road trip. This lens was perfect, and I love it. It's my shiny silver buddy who's fun to be with.

This lens filled the "travel lens" niche perfectly. It's lightweight and reasonably small (about the same size as my 31mm Limited, but lighter), so I can carry it with me almost everywhere. The 20-40mm zoom range covers the focal lengths I most commonly use, though I should note that I brought along a second K-3 with the 15mm Limited. The f/2.8-4 maximum aperture seems a little slow, but in practice, I never had trouble using it indoors. When I'm visiting museums, I tend to use the wide end anyway, and f/2.8 is fine. I never had to test the weather sealing, but it was very good to have it.

As far as image quality goes, the 20-40mm Limited is fantastic. The sharpness, color saturation, and clarity are simply outstanding. It stacks up well against my other Limited lenses. (I put together a whole gallery here, if you're interested).

-- It's sharper than the 21mm, and has comparable bokeh; at this point, the choice of which one I bring with me mostly depends on whether I want the smaller lens, and whether I need the weather sealing.

-- It's very slightly less sharp than the 31mm Limited, but you'll only see the difference if you are a fanatical pixel-peeper. The rendering and the bokeh are noticeably different to me between the two lenses. I think the 20-40 reproduces colors more vividly, but I think the bokeh of the 31 is smoother, and I generally prefer its rendering.

-- The 40mm Limited wins for sharpness, but then again, it's the sharpest lens I own; the 20-40 is also very, very sharp. The color saturation and rendering are generally comparable.

I only have a few complaints, and they're relatively minor. The autofocus is noticeably worse than the 21, 31, or 40-- sometimes it hunts around for a while, and sometimes it latches on to something, and sometimes it doesn't. I'm not sure what's going on, but my primes don't have this problem. Next, there's noticeable vignetting at 40mm at f/4.0, but this can be cleaned up unproblematically in post. There's noticeable distortion at 20mm, so if you really like to photograph straight vertical lines near the edges of the frame, you might be sad. Finally, the silver finish on the lens hood rubs off relatively easily.

In short, it's a wonderful little lens, and unless you really need a wider zoom range or a larger aperture, you won't be disappointed.

Enough talk! Now photos!

20mm @ f/11. You can see how well this lens nails textures...


...and colors.


20mm @ f/7.1 You can see a noticeable amount of distortion at 20mm, more than the 21mm Limited, I think.


23mm @ f/3.5. Just throwing in a photo at a relatively wide angle and a relatively wide aperture.


29mm @ f/5.6. See, it does reasonably well indoors.


30mm @ f/3.5. An example of the bokeh. It's quite nice!


31mm @ f/11. It's still sharp at the middle of its zoom range.


34mm @ f/11. Ditto.


40mm @ f/4.0. You can see what I was talking about with the vignetting, but IIRC there were more egregious examples.


40mm @ f/11. Still sharp.


40mm @ f/4.0. It's not a fast telephoto lens, but it still does reasonably good portraits.


Anyway, if you really cannot get enough example photos, the entire road trip album is here.

It's a great lens! It got, I think, unfairly slammed by confused lens reviewers who didn't think through the handling/portability implications of the relatively slow maximum aperture, and who didn't appreciate the pixie dust. The original price of $1,000 was pretty steep, and I certainly wouldn't pay that much for it, but $600 is entirely reasonable. If you do end up buying it, I hope you enjoy it as much as I have!

Knowing how anal most review sights are about technical specifications I read the reviews with a pinch of salt. I have the classic limited primes and have always admired the amazing rendering of colours, focus transition, local contrast, and accurate colour separation and definition within complex images. The 15 f4 ltd is my favourite. Appreciating the complexity of design that is required to re-create those characteristics in a zoom, I am very happy with my 20-40 ltd. It maintains the same character in performance as the limited primes. Considering this and the amazing construction I would consider it an absolute bargain.

Pros: Image Quality, Build, Handling, Zoom range, Size and Weight
Cons: None
Sharpness: 10    Aberrations: 9    Bokeh: 10    Autofocus: 9    Handling: 10    Value: 10    New or Used: New    Camera Used: Pentax K-3 II   

This is an extraordinarily good lens of perfect build quality.

Optically it's among the best on the market (I've tested mine against some renowned lenses - and it more than holds its own):

IQ is gorgeous being razor sharp at practical working apertures (I do not venture farther than f/11 on any lens, if I can help it). More over CA's, fringing (if any at all) and distortion are negligible. Flare and reflexes are next to non-existent (Sigma Art's are a pain in this department), and it does an unbelievable job of retaining information and details in highlights and shadows (something that distinguishes excellent lenses from the rest - ask Leica-aficionados).

The zoom range is perfect for street photography and the likes, and the size and weight of the lens - though larger than the rest of the DA-Limited lenses - are non obstructive. The Sigma Art's are way to large and heavy in comparison (I do, in fact, own a couple of them). On top of that, I do prefer lenses from the camera producers, as they do have their brand much more at stake - also in the mechanical build department - as compared to third party producers.

Did I forget to mention the Bokeh? Smooth, lovely and unbelievably buttery for a zoom - then again, this seems to be a prime lens with a variable focal length-type of lens.

IMHO this piece of Pentax-glass is worth every last penny - and if you still don't believe it, please read this review:

Clearly a FIVE STAR Lens. And Pentax does make a lot of them ...

I was searching for a better walk around lens than the Kit -
and I have a great collection of K,M,A and M42 Lenses , so I like the look
and the feel of it as much as the extraordinary quality of this lens !
You have to try it to say such things - and after setting the right Focus in my K3,
there is no doubt about the optical quality as well !
This is the right Lens I expected for my needs - lovely rounded Blades give a nice bokeh even at 20mm ;-) For more angel I take my 15mmLtd. or my 10-17mm fisheye with me ... It give a nostalgic feel in f2,8 and is extra sharp from 3,6 / 4 upwards - like also the 3D Rendition especially for HDR-Shots !
A quite good reason to stay with my lovely K3 Prestige Edition ...
Not cheap, but the output gives the answer !
Highly recommended !
