Description:

This 12-24mm extreme-wide angle zoom lens provides a useful range for landscape and street photography. An alternative would be the heavier and more expensive DA* 11-18mm F2.8 lens.

Pros: Superb color rendition, beautiful rendering, sharp
Cons: CA, distortion

Given the inherent limitations of lens technology, it’s hard to imagine a better landscape lens for APS-C cameras. The focal range is eminently well suited for capturing the splendor of the great outdoors, giving one the 35mm equivalent of an 18mm to 36mm lens — in other words, right in the sweet spot for vista-type landscape shooting. This lens will give you deep, rich, blue skies without a polarizer; it will capture shades of dark, verdant green that elude many other lenses; and it will produce results, in terms of micro-contrast, comparable to the clarity slider in Lightroom without the halos. All in all, the lens seems tailor made for producing spectacular landscape images.

As with all ultra-wide angle zooms, this lens will present some distortion and CA issues. That's merely the price to pay for going so wide. The CA issues (e.g., blue fringing toward the corners, occasional green and red fringing) can, in the vast majority cases, be either removed or severely mitigated by adjusting a few sliders in lightroom (i.e., it's not really a serious issue).

Like most Pentax zoom lens, resolution is at its peak toward the wide end of the lens. It loses a bit of resolution at the long end of the lens, but it’s not enough to cause serious concern. At 24mm, the DA 12-24 is still a heck of a lens.

Pros: Great clarity and color
Cons: Very expensive and climbing
Sharpness: 9    Aberrations: 8    Bokeh: 8    Autofocus: 9    Handling: 10    Value: 8    New or Used: Used    Camera Used: K-5 IIs   

I would rate this lnes very high in it's class. I have a Tamron 10-24mm and the Pentax totally out shines the Tamron. The difference is very noticeable. I used the Pentax 12-24 mm for architectural photography while my Tamron was in for repair under warranty.
The true F4 aperture is very nice to use throughout and does seem to be nicer than a shifting aperture. I was real happy using this lens. I used it on three jobs taking about 1500 shots with it. It helps that it was on an K-5 IIs. The sharpness from center out is very good and noticeably sharper than the Tamron. The Tamron is real soft on the edges. The Tamron is nice for the money but if you can afford it, buy the Pentax and you won't wish your Tamron could do more. The Pentax 12-24 mm all around delivers very good pictures and the pictures are not just sharp but very good in all aspects. it is a pleasure to use and my confidence grew the more I used it.
The following photos were shot in RAW and sharpened in PP after they were cropped to the smaller size. If their original high resolution size, they did not need any sharpening.

Pros: Lack of distortion, focus speed, colors, flare
Cons: $$$, hood size, tiny amount of PF

Hi All,

I am doing a little LENS review of the DA12-24 as well

What i will do is compare it to the two other lenses I have near this focal length, the DA*16-50 and the DA18-55.

Firstly, the lens slots in nicely between the DA*16-50 and the DA18-55 in quality of finish. It is weighty - close the the DA*, has a solid feel to it and it beautifully finished, with blend of metal and plastic parts and rubber grips.

The front lens element does not rotate and therefore is easy to use with a Circular Polarizing filter.

The hood is quite large and almost overbearing compared to the lens itself, but totally worthwhile with such a wide angle lens, helping to stop unwanted flare.

USING THE LENS
The most dramatic thing about this lens is the lack of visual image distortion, even at 12mm it is almost undetectable, while going from 13-24mm IS perfect without any distortion whatsoever.
At 12mm F4 the image is sharp and marginally sharper at F8 tapering off at F13-F22.
I dont find 24mm as sharp until F8 but elsewhere in the range up to 22mm is as good as 12mm.

Comparing images from the DA*16-50 and DA12-24 finds very little difference at 16mm and 12mm. They both have about the same Resolution and sharpness and little purple fringing where there are strong colour contrasts (white and blacks).
The DA* shows some barrel distortion where as the DA12-24 shows virtually none.
Colours on both lenses are superb, flare is really well controlled and it is impossible to say which image is from what lens.
The DA seems to lock focus extremely quick and accurately perhaps fractionally faster than the DA* and about the same as the DA18-55.


Conclusion :th3: :th3: :th3: :th3: 4.5/5
Lets face it, you buy this lens for the wider side of its design, from 12mm+ and mostly for landscapes, interior/exterior real estate and street work.
F4 may not sound like much but it locks focus fast and depth of field around this focal length is DEEP no matter how close you are.

Image quality is 2nd to none and matches the DA*. In fact it is the perfect compliment for the DA*, extending the range to 12mm and loosing nothing at all in quality and resolution.

The hood will fit on the DA* as well.

Things to look out for when using this lens-
Looking up or down when there are geometrical shapes in the image will create massive amounts of perspective distortion. This is not a lens issue just a something thats happens at these focal lengths that you should be aware of especially when taking real estate photos for example.

CONS-
Purple Fringing. It has some, not as bad as the DA* and not enough to really worry about, but look and you will find if youre into pixel peeping. K7 fixes this, so does PS.

No Bag come on, give me a bag when i spend this much

COST = $1000 to $1150 Shop around !!!

DA12-24 @12mm (notice just how much more you get for 12mm compared to 16mm and complete lack of barrel distortion! not much PF to see either)


DA*16-50 @ 16mm (note PF in the lights and slight barrel distortion)


DA18-55ii @ 18mm (slight barrel distortion)



Looking up (perspective distortion, trees bowing in towards the middle)


Looking straight out, perfect image quality, some PF, HERE is where you need 12mm

Pros: sharpness, weight, quickshift
Cons: non-WR, discontinued, screw drive
Sharpness: 10    Aberrations: 7    Bokeh: 8    Autofocus: 8    Handling: 9    Value: 10    New or Used: Used    Camera Used: K-70   

I've owned a Sigma 10-20/4.5-5.6 for several years, and fell in love with the ultra-wide range, but was very much underwhelmed by edge sharpness.
A used DA12-24/4 came up for sale here on PF, and after reading all the reviews, I was prepared to take a leap of faith.
My preference would have been the DA* 11-18, but even used, they're 3x the price of a 12-24, and I'd need to sell some photos to justify such an expense.
The 12-24 is a significant upgrade over the Sigma 10-20 in almost every respect at the expense of loss of 2mm at the wide end.
Sharpness across the frame is vastly improved, rating up there amongst the sharpest zooms I've used, and the convenience of quickshift is something that's hard to live without once you've got used to it.

As described in other reviews, the lens can suffer some CA, but nothing that can't be fixed in software.

For the loss of 1mm at the wide end, and one stop of aperture, the 12-24 is around 300g lighter than the 11-18, with the added bonus of extra reach at the long end.

It's screw drive vs DC motor in the 11-18, but in practical use I haven't found that an issue, and it's a small price to pay for a much cheaper, lighter lens.

This has been handy for me, as I have a bit of an odd setup for APS-C with a D-FA 28-105 as one of my most popular lenses. A DA 16-85 would be preferable, but it's heavier and I picked up the D-FA 28-105 very cheaply, and only having a 4mm gap in focal lengths isn't too bad. The 12-24 also makes the D-FA 24-70/2.8 a possibility with no gaps in focal length, for a similar price to the DA*16-50/2.8 but with a bit more reach and full frame compatibility.

The only significant fault I can find with the lens is lack of WR, which was one of the reasons its previous owner was selling.

If you want to take photos in dust storms, salt spray, or at waterfalls, this isn't the lens for you, however if you can avoid these environments it's excellent value for money as a landscape and architecture lens.

If this was re-released in a WR version, possibly with updated coatings, as an (HD)? DA 12-24/4 WR as Ricoh has done with several other DA zooms, it would be an even more desirable lens to own.

Pros: Sharpness, fast. Versatile zoom for landscape, architecture, photoreport.
Cons: Some CA and fringing but can be remove in post prodution
Sharpness: 10    Aberrations: 7    Bokeh: 10    Autofocus: 10    Handling: 10    Value: 9    New or Used: Used    Camera Used: Pentax K-3 and Pentax K-1   

I was searching for a lens that was versatile enough for take landscape, interiors, street photograph and photoreport and very important tha was compatible with not only my K-3 but with my new K-1. I Know that there is the newest DFA 15-30 but it is most expensive for the use I will make for. So I search here in the reviews and despite the CA and some distortion due the WA lenses create and that is assumed in that review I decide to buy one used on Ebay for 590.00 €, witch is afforfable for me. Furthermore I need a 24-70 F2.8 and it is not cheap as all of us know. But in this case I will consider de Pentax new one (). Well and the first results are very nice for me and I am very excited with. Well there is in fact some CA and fringing but well removed in post prodution in LR, is very sharp indeed since 12 to 24 mm. So In my opinion I am very satisfied with this lens for the kind of photo I like to take. Hope I can help someone with this review.

Pros: Sharpness, color render, AF
Cons: CA, Corner performance, sharpness at 20-24mm
Sharpness: 10    Aberrations: 7    Bokeh: 7    Autofocus: 7    Value: 9    New or Used: Used    Camera Used: K-7 & K-5   

Bought this lens in October 2010. Used it quite frequently for indoor and landscape photography, albeit I like primes more.

To be short - this is a very good lens.

I'd say If you are into landscape photography your best shot is 12-24 mm (18-36 mm (full format equivalent))

Sharpness at 12mm in center is very good, far corners are a bit mashed.









Sharpness at 24mm is not so great, but for me it is good, and much more than just usable.







For me, the petal shaped hood is very uncomfortable to use. It's big clumsy plastic pain in the *rse.
Typically for Pentax lens, the flare resistance is very good.
Auto-focus works a bit more faster, IF helps here. Oddly for such wide lens it misses some times (or tries to do so). Hunts in the dark too. A LOT OF hunting actually. Some times it becomes impossible to take picture!

CA and distortion are not a problem, if you are using in camera processing or shoot in RAW and the post process in Lightroom.

As a summary, I recommend this lens if you are not afraid of its size or flaws.

Pros: Good color rendering. Convenient wide-angle focal lengths. Not as heavy in weight as it may seem on the basis of its dimensions. Good sharpness.
Cons: Big size. Very large blend. Large diameter of the front lens (expensive filters with a diameter). Chromatism. Pretty expensive cost.
Sharpness: 9    Aberrations: 7    Bokeh: 8    Autofocus: 9    Handling: 8    Value: 7    New or Used: Used    Camera Used: К5   

I have this lens recently. I bought it by accident. But when I tried to photograph them, I was pleasantly impressed with the results.
The lens has a good color reproduction. And good sharpness of photos. Sharpness is better at 11-15mm focal length, already at open aperture values.
The focal length of this lens is quite convenient on cropped cameras. The lens can shoot groups of people. But it is not intended for this. Its purpose is photography of landscapes, street photography, interior and architectural photography, night photography.
Surprisingly, this lens has more or less normal bokeh. In any case, the bokeh of this lens is not annoying. Bokeh is not easy to get. Because the lens has a very large depth of sharply depicted space.
When shooting with covered aperture values ​​(8-11 +) lights and other light sources at night get beautiful rays.
For interesting pictures with this lens, it is advisable to use a photo tripod.
The lens hood is also very desirable to always use. It not only cuts off the extra light.
*Rays due to which glare may occur. But it also increases the overall contrast of the photos.
Buy a protective filter for the front lens of this lens. The diameter of the lens is large and expensive filters for it. But filters are needed to protect the front lens of the lens, which has a large diameter.
Auto focus at the lens is fast, accurate and produces little noise.
I compared this lens with 16-45 F4. At a focal length of 16mm. 12-24 lens gives a better (sharper and more saturated) image than 16-45. On any diaphragm. And already at focal lengths of 20-24mm., These two lenses take pictures almost equally well.
Conclusion: I really liked the lens. The disadvantages are insignificant compared to its merits. To the main advantages, I would take good sharpness, convenient focal lengths, fast focusing.

Pros: Good build quality, Much Sharper than expecting, Light weight, Fast/Precise Focus, Acceptable distortion for range,
Cons: Large filter size (expensive filters), Noticeable CA (easily fixed in post)
Sharpness: 10    Aberrations: 9    Bokeh: 9    Autofocus: 10    Handling: 10    Value: 10    New or Used: Used    Camera Used: K3   

I have wanted this lens for years, but new, they can be costly. I was fortunate enough to purchase my copy from another forum member and secured a very sharp copy that was in mint condition for a cost that was fantastic.
This could be the best Pentax purchase I've made to date.
This lens performs!! Surprisingly sharp, light, handles well, focuses quickly and distortion is very low given the focal range. This is truly one of Pentax's crop jewels.

The following shots are from a local Micro Brewery on the first day I'ld owned the lens;

Pros: Superb 12-18 range and IQ for landscape or interior
Cons: Some purple fringing in few particular cases
Sharpness: 9    Aberrations: 7    Bokeh: 9    Autofocus: 9    Handling: 9    Value: 10    New or Used: New    Camera Used: K5 K1   

I use this with a k5 only within the 12-18/20 range and almost 75% in the 12mm.
F4or F5,6 for indoor and F8 outdoor landscape, it really shines in these settings.








I shot outdoor and indoor pics
Some night ones too :


For an UWA lens, Outstanding IQ in center , very good borders.Contrast and Colors are Pentax da so really good!

Some people says some AC and purple fringing. Of course if you shoot a very high contrast situations such a tree in automn in foreground with white sky, you will see the best purple Fringing on the branches in the corners you probably ever seen, quite like quasi all lens, but much more here. .
The fact is that in the most most of the time in normal situations , you won’t feel and see it even printing on a A4 size.
Of course if you magnify x2 or x3 on your 24”pc screen, you won’T miss it.
Hey it’s an UWA so if you take a pic and want to be able to crop it quite generously without bother with Ac , choose a 50mm and take care of your composition!!!

For me, This lens is mandatory with an apc for the 12mm FOV and because it’s such a higher quality In IQ/clarity in the 18mm range already at F4 comparing to a normal zoom such a 18-135 at F8 for example.
At the opposite, The 24mm range of the 12-24 is not the best (but still very good at F8) comparing with the 18-135 which is normal as the 24-50mm range for my copy is the (only but quite superb ... but quite restricted range for such a zoom...) point of strength .

Look at the 77mm if you want use a (mandatory very high quality)polarized filter so Extra cost, personally I tried with and considering the FOV I found it useless and finding it gave too too much sky contrast to an already contrasty lens.

It’s a specialised purpose lens but for wide shooting it’s a winner in Pentax world.
The price can be high as new but finding one used Cheaper in very good condition can be a solution as it’s usually not a daily use lens.
You can’t be disappointed , try it !!!

this is it for APS-C only even if it works on apsc mode with the K1. For FF now i use the FA 20-35mmF4 (this one no interesting for APS-c/ range) as I hate this kind of restricted black border Windows in my OVF no way. Will post a review of this FA when more exhaustiv use but it smells very very good (35mm much much better than the 24mm of the 12-24

Pros: Sharp, few optical aberrations.
Cons: No weather resistance. Size.
Sharpness: 8    Aberrations: 7    Bokeh: 8    Autofocus: 8    Handling: 8    Value: 9    New or Used: Used    Camera Used: K5   

Bought this lens used on Adorama... Had to buy a hood separately.

Just love this lens! It's already very sharp wide open, with only the corners lagging a little bit behind. Wide open at 24mm is indeed (as many reviews pointed out) a bit softer, but not enough to prevent shooting at F4 if in low light situations as far as I'm concerned.

Regarding the lateral chromatic aberrations, they are rather pronounced on this lens, especially at 12mm. They can be corrected almost entirely and quite easily in post-production if you shoot RAW, though (which I always do). The vignetting is also a bit on the high side wide open, but is well under control from F5.6 and beyond. Distortion is visible at 12mm, but rather impressive for such an ultra wide angle lens. It is certainly lower than that of a standard zooms like the 18-55mm kit lens (or the DA*16-50mm F2.8 [IF] ED). More important, the distortion is easy to correct, with no mustache-like pattern.

The bokeh is surprisingly good! You need to be very close to your subject to get a decent background blur, but the out of focus elements have quite an appealing look for such a wide lens. Thankfully, this lens allows you to get very close, and with a decent magnification ratio on top of that.

Flare is also well-controlled for an ultra-wide, even without the lens hood. I tried the Sigma DC 10-20mm F4-5.6 lens during a stage event once, and though the lens performed very well in terms of sharpness and CAs, it had two flaws (besides its variable aperture). One of them was small—its slight mustache-like distortion. The other—a major issue—was flare. Facing the stage, with the spotlights in the frame, the results were extremely disappointing: the pictures were full of irregular flare patterns with multiple colours that reminded me of iridescence. It's like the spotlights had vomited their light onto the lens. The Pentax DA12-24mm isn't affected by such issues, with a flare that's actually pleasant when facing spotlights (though it's a matter of taste to some point).

Focus speed and accuracy are rather impressive on still subjects.The fastest AF lens I have ever tested.

The only things I could complain about are its rather big size (though in line with similar lenses) and the lack of sealings to provide some resistance against harsh weather.

All-in-all, I highly recommend it. If the dramatic perspectives of an ultra wide angle lens is your thing, you'll never get tired of this lens.

Pros: tone and color rendition
Cons: chromatic aberration (purple fringing)
Sharpness: 10    Aberrations: 1    Bokeh: 8    Autofocus: 9    Handling: 8    Value: 5    New or Used: New    Camera Used: K3   

A marvelous zoom with a big flaw: chromatic aberration.
When I bought it - nine months ago - I knew what I was getting, the in-depth review by the staff here at PentaxForums states very clearly that the CA issues of this lens can't be mitigated by stopping down, but my experience on the field with this zoom has been a nightmare, maybe I have been unlucky with the lens I have bought, I look at the picture posted here by mujahideen last August and I think: I could never get this shot with my lens.
The purple fringing issue in most cases is so acute that the automatic correction by the softwares I use - from Darktable to LightZone to RawTherapee - has been useless. Tree branches populate my photographic nightmares, you don't need hi-contrast situations to get CA with this lens, even a minimum shift of light in your image makes the tree branches going on fire.
I shoot RAW + JPEG (sometime I just need the photo NOW) but JPEGs are useless, while RAWs requires a lot of PP work that in some extreme cases doesn't solve the problem, if you are planning to buy this lens, buy it from a seller who is willing to let you test it for a few days - from what we gather from the reviews here where some people have rated the CA of this lens with a 10, the production quality is quite unstable.

Pros: Solid performer, excellent autofocus, great for close up / detail shots
Cons:
Sharpness: 8    Aberrations: 7    Bokeh: 8    Autofocus: 9    Handling: 8    Value: 6    New or Used: New    Camera Used: K20D   

Reading a pervious review of this lens here dated 13 October 2013, I felt compelled to write my own review because that user has had a very similar experience to me. I am a real estate photographer and had previously been shooting with the Sigma 17-50mm F2.8 EX DC. I regard this lens as excellent and would rate this a 9 or 10 as it produces very sharp 'wow' images, with excellent colour, exposure etc. Finding that I needed a wider lens for interiors, after quite some deliberation I purchased the Pentax 12-24 F4. I would rate this lens a 7-8 because it is not quite as sharp or 'wow' as my Sigma 17-50 [except when taking detail close ups at F4 / 20mm, where IQ and sharpness are excellent] . However, that is not to say the Pentax 12-24 is a poor lens. Quite the opposite! It is a great solid performing lens - the main benefit to me is that it obviously can go to 12mm (19mm with the 1.6 factor) and can therefore capture far more than 17mm (27mm) can. It performs well in high contrast situations (i.e. sunny window and dark room corner in the same shot) with great colours and the sharpness, and whilst not quite as good as the Sigma 17-50, is still totally satisfactory. I wonder though if the Sigma 10-20mm (which I understand is in the brilliant EX class) would have been a sharper lens? Or perhaps I am being too picky, as the trade off for having such a wide lens is perhaps a minor loss of sharpness anyway.....

Pros: Sharp wide open, fantastic colour and contrast, build quality
Cons: Hood creeps into the field of view at 12mm if you are not careful
New or Used: New   

I own the 77, 21, 50 and 35mm primes but frankly the 12-24 is a more consistent lens than all of them. It's sharp at f/4, sharp in the corners a stop down with outstanding colour and contrast.

I have found CA's to be minimal, my only real complaint is that if the hood is not screwed on fully it intrudes on the image severely at 12mm. The hood is large and this makes the lens hard to carry (it's not a big lens sans hood) but with this FOV you have to use the hood.

Flare is very well controlled and build quality is first rate with snappy AF and quickshift.

This is what all lenses should be like.

UPDATE MARCH 2012: Had the lens a while now and fringing where trees meet the sky is a real pain and something to be very aware of. The price of the lens has also doubled since i bought it and at that price, Sigma becomes a reality.

Pros: Sharp, versatile wide angle zoom, very low distortion
Cons: Bulky (but necessary) hood

Wide is good. This lens is excellent! I'm very happy with this lens since I prefer rectilinear for landscapes.

Sharpness 9
Bokeh 9 (but with huge depth of field)
Color 9
Handling 9 (hood is a bit bulky, but absolutely necessary)
Build 8
Distortion 9 (better than Sigma, etc.)
Aberations 8
Value 7 (will probably revise upward the more I use it - big investment!)

I didn't plan on getting the 12-24 right away, but my local shop had one in stock, I played with it a while and took it home. Very glad I did.
