Pros: 8mm, sharp, really no competition
Cons: Big, can flare, soft corners until stopped down

Overall, unlike the 10-20mm, one needs to learn how to use this lens to get the most from it. If you just set it to 8mm and shoot like you would with any other lens, you will get shots that look like the subject was too far away. You need to actively seek-out unusual perspectives, and the rear LCD comes in handy for letting you see what the camera sees when your face cannot get there. This lens does give a much more ordinary perspective around 16mm, but I think the 10-20mm will give most casual photographers a higher keeper rate. That said, the center sharpness of the 8-16mm would allow significant cropping to save many too-distant shots.

Unlike the 10-20mm, which needs to be stopped down a little, this lens is very sharp in the center wide open. Stopping down helps edges and hurts the center. The corners never quite catch up to the center at 8mm, but everything is more than acceptably sharp by around f/8. I've found myself often using this lens at f/14-f/22 to get even sharpness on everything across the frame at all distances -- but your sensor and the lens front (yes, things on the lens front are nearly in focus!) need to be absolutely spotless to get away with that and not have to go removing little dust shadows in post processing... a little unsharp masking is also useful to restore the sharpness that diffraction took away. Depth of field (DoF) seems less as you move away from the center at 8mm... not an effect that I saw on any other lens.

Colors seem very intense, but ultrawides do that.

Build is usual Sigma, lightweight yet solid. I do not care that it cannot take a filter, but the curvature and the fixed hood do make it harder to get a lenspen to the edges. The cap assembly needs to be aligned just right to put it back on the lens, which is a little annoying. The built-in hood does keep you from accidentally pushing the lens into objects you are photographing.

Distortion is about 3% at 8mm, which is good for everything but architecture and really impressive for such a wide lens. Distortion is negligible between 12-16mm.

It is hard to get the lens to flare, but when it does you can get brightly colored dots. They are easy to edit out, but disturbing when present. I've also gotten a bit of a ring around the sun in a few photos, but flare is really well controlled.

Despite the short focal length, focus does indeed matter. I have the Sony version and let's just say there are problems with autofocus. Using manual focus, it is clear that the focus scale shifts significantly as the lens heats-up or cools in ambient temperatures from 20F to 110F, and that's probably why the autofocus has some issues. I don't know if the Pentax mount version has the same problem, but I expect it does.

One last comment: I went on a 6,500-mile driving tour of the USA west several months ago, and this lens was used for more than 1/3 of the photos I took... easily my favorite lens for the trip. It is hard to use well -- you really need to be very careful about getting close, searching-out good angles, and watching what sneaks into the edges of the frame, but it allows me to make photos that none of my 100+ other lenses can. With very careful composition, you really can capture the feel of expansive western landscapes that less-wide lenses cannot. I had a fisheye along with me too, but the ability to zoom a little on this Sigma, combined with the lack of guessing about how de-fishing will leave things, makes for much more accurate composition and thus consistently superior photos. This is why 10 overall.

Pros: Sharpness, rendering of skies
Cons: AF, inability to fit filters

I love this lens, 8mm is pretty impressive! There's nothing else available at 8mm apart from fisheyes. I was lucky enough to pick one up second-hand.

The cons are minor niggles really. It's a bit soft at the corner and edges when wide-open. It's very sharp stopped down, and, personally, I want as much DOF as possible on UWA shots, so for me that's not normally a problem. Likewise, the autofocus: it's not very good, but I rarely use it anyway, so it doesn't bother me. I prefer to use hyperfocal focusing with UWA lenses. If you do use AF, use Spot Focus, as I think part of the problem is there's so much in the frame it doesn't know what to lock on to. For anyone wanting to shoot infrared with this lens, forget it. It suffers from hot-spots at all apertures.

The pros are it's angle of view, it's sharpness when stopped down a bit, and the way it renders skies. It's like it has a built-in polariser, and for me that largely negates the inability to use filters. In the Middle-East, with skies often a dull beige from sand in the air, this lens delivers beautiful blue skies. It's quite extraordinary in that regard. Contrast is excellent.

One other con, but fixable: Pentax cameras don't recognise focal lengths below 10mm, so you need to use a program like ExifTool to modify the exif if you want to use lens corrections below 10mm. It's worth doing this, as the distortion is quite odd, moustache-type, and the edges become very distorted at 8mm.

Overall I'd give this lens a 9, only not getting a 10 because of the AF issues, and it's softness at the edges when wide-open.

Pros: Sharpness, build quality
Cons: Sigma rendering (but not as prominent as usual)

It looks like Sigma has recently discontinued this lens in Pentax mount. If they don't offer a replacement, that's horrible news. I'm not a Sigma fan, but this one impresses. It exhibits some of the typical Sigma image rendering (which is a negative to me), but it's only about half as noticeable as other Sigma lenses I've used.

Perhaps this lens isn't a "real" 10, but within context, given its constraints (zoom, widest Ultra Wide Angle available, APS-C design, K-mount, relatively slow aperture) it's amazing - definitely a 10. It's surprisingly sharp. On mine, the infinity focus mark is exactly spot-on. For most shots you simply turn of the AF, set the focus to infinity, set the aperture to around f/6.3, and zoom to somewhere between 10 and 16mm. You'll get tremendous DOF (from about 3' to infinity) and a sharp image throughout most or all of the frame. Setting the focus to even slightly less than infinity quickly compromises the sharpness of anything more than a few feet away. Usually AF will do this to you. So if you go outside of these parameters, you may not be as happy with the results. Most of the time you set a fixed focus and aperture, then concentrate on just zoom and composition.

At 10mm it puts the Sigma and Tamron 10-20/24s to shame. It's not a fast lens, and images from the DA15 are a little nicer. But when you can go to 10 or 8mm wide it's a whole different ballgame.


You could do better if you had a Nikon FX camera with a 14-24mm lens. But that's an ~$4000+ proposition. Adding this to your existing Pentax DSLR yields excellent results for a modest investment.

Pros: Widest lens available for apsc
Cons: Inconsistent metering on k3
Sharpness: 7    Aberrations: 8    Bokeh: 7    Handling: 9    Value: 9    Camera Used: K-3    Autofocus: 10   

I'm not sure why this is listed as a legacy lens - it's listed on the sigma site as a current lens, and can still be bought from most shops?

Anyhow, if you need ultra wide, then there aren't many alternative options. This lens is better than the DA12-24 (my copy will be heading to eBay soon), but the DA15 beats it at the long end.

The sharpness is reasonable for a zoom, bokeh is irrelevant when you're this wide. However... Metering on the k-3 is pretty bad. It just seems the k-3 can't cope with this lens (it feels like it's so wide the k-3 doesn't know what it should be metering?). Some times it's over exposed, sometimes under exposed. It just seems to be a bit of a lottery. The images clean up fairly easily in Lightroom, and you will end up with good shots, but if you're a JPEG shooter, you should probably avoid this lens.

If you want the best wide angle lens, this is not it (the DA15 is). For those days when the DA15 is just far too narrow for you, or when you feel the need to have your legs and feet in scenic landscapes, the 8-16 is just the ticket

Pros: mind blowing angle of view, IQ, sharpness ,well build
Cons: flare

PLEASE STOP spreading wrong rumours !
It is available in Pentax mount and will be in the foreseeable future.
The production is limited so you might have to wait a while for the stock if you want a new one.

I was waiting ~ 4 months for new stock in Australia but it was worth waiting for.
It looks great , works great and is a joy to use.
With new 24MP K-3 you can take full advantage of lens sharpness and IQ, love it!

My overall score : 9.5

Pros: widest rectilinear lens available, good sharpness wide open, very good distortion control, very good build, fast accurate silent focus
Cons: somewhat prone to flare/CA at 8mm, K-5 does not recognise 8mm, exposed front element, lens cap is a pain

There is 1 IQ con to this lens that makes it 9 instead of 10 because at 8mm with aperture below f8.0, it is somewhat prone to flare and chromatic aberration. Take note that I'm thinking 10 as in perfect so although the degree of flare and CA is minute, it still can be seen in the right conditions. So it's not perfect.

Other than that, IQ is close to perfect. Sharpness is good even wide open. Distortion even at 8mm is only noticeable if you actually take a straight ruler to measure. Build quality is also very good. AF is fast, accurate and silent (though I don't expect anything less from HSM wide angle)

There are only 3 minor annoyances.
  • The front element is exposed (i.e. can't use protective filter). I know it's unavoidable (and some people will argue against protective filters anyway) but it definitely makes me a little bit more concious about things knocking on the glass.
  • Pentax K-5 does not recognise focal length below 10mm. If you check focal length, it's just blank. When you are at 10mm, the focal length marvellously reappears. It's annoying because Adobe Lightroom needs the focal length information to perform automatic lens correction.
  • The included lens cap is a pain. There is a adapter tube which has 72mm thread. You need to put on the tube and then put on the removable 72mm lens cap. I wouldn't be complaining about it if the tube does not cause dark corners.
    So why not just make the tube itself a lens cap instead? You can buy 72mm metal screw-in lens cap from ebay and it will convert the adapter tube into an (even better) lens cap.

I love architectural/landscape HDR and this lens is golden for that purpose!

Pros: incredible angle of view, razor sharp, well built
Cons: slow (but isn't a problem for this kind of lens)

This is a unique lens design on the market, there aren't any other similar lens that provide a similar angle of view (except the Sigma 12-24mm f4.5-5.6 and Voigtlaender 12 mm f5,6 UltraWide Heliar that however are for FF).

It shows a great sharpness all around the frame, whit rich colors and beautiful contrast.

The maximum sharpness is achieved at largest apertures, that it's great.

The only problem for me is the fixed lens hood.

====> VERY INTERESTING: this lens may cover the entire full frame by removing the hood!!! these are not assumptions because if I put something between hood and lens, I can clearly see it.

I heard that someone removed the hood and the lens works great with old film camera, providing an incredible wide angle!!

Pros: Nice finish, unequaled FoV in APS-C, not a fisheye, near silent.
Cons: Big!

This lens is really great!
For architectural shots, it's a sheer pleasure to use. The 100+° horizontal field of view is simply amazing for interiors, meaning that from a corner you can shot a whole room from wall to wall!
Landscapes becomes real challenges in avoiding unwanted elements in the composition, and I often ended up with my feet somewhere in the pic! (Note for users : avoid placing a face near the borders!)
Also, something to note for landscapes: it feels like there is a CPL included! Skies are a deep blue, whereas similar exposures with the kit lens often resulted in washed-out skies... Quite strange...

Image quality is great, aberrations are minimal and distortions are quite negligible.

So, this lens is exceptional, but it is really a specialist lens...

Pros: truly widens your photography into an inspirational world
Cons: Bit slow, flat colors
Sharpness: 8    Aberrations: 9    Bokeh: 1    Handling: 10    Value: 10    Camera Used: KP    Autofocus: 10    New Or Used: New   

It's a spectacular lens with an unbeatable (and rectilinear aka not fish-eye) diagonal angle of 122° and a 115° horizontal at 8mm that opens up a whole new world in photography.

Most enthusiasts turn into the other extreme with telephoto lenses shooting in open space mostly wild life etc. This type of glass give us the ability to find amazing captures in urban and close environments. The "ultra wide angle" is a place that few have realised its potential or see it as a hobby since the rectilinear options are..... well... just two. Either this or the way more expensive DA* 11-18 since there is a huge difference with all the fish-eye available that distort reality. Actually it's the only lens in Pentax that can deliver 8-11 angles.

It delivers magical images, (there is no bokeh beauty in such angles) and gives you the alternative to get a great hobby.

Save for real estate agents, this glass and these angles, I promise, make my soul living in a tight metropolis
open up and fall in love with it's "enclosure".

I wrote on the Cons that it's not for amateurs yet it can initiate everyone into this magical world of rectilinear reality.

You can use a tripod of take advantage of the SR since at 8mm landscapes can be shot handheld even at an 1/8th - of a second unlike in wildlife where you need speed and subject sharpness.

It's the ONLY lens that makes the WHOLE photo the a full subject. And that's second to none.

Pros: W-I-D-E, 20% wider than 10-20, sharp, IF, HSM,
Cons: NO Filters, Price, Slow
Sharpness: 9    Aberrations: 9    Bokeh: 7    Handling: 8    Value: 8    Camera Used: K-5iis K-3    Autofocus: 10    New Or Used: Used   

If you are into filters this is NOT the lens for you. If you want to shoot rectilinear and WIDE then this is the lens for you. Sharper than the 10/12-20/24 lenses I've shot over the years, silent, fast focus, but it handles like a fisheye with regard to the hood being built in, the glass bulging outward a bit, and needing to really be aware of your own body when framing the photo. Stopping down to f8+ brings the corners into sharp relief but the center is sharp from the outset. Distortion is lower, so far, than I anticipated with is a nice realization. I'm being asked to photograph in tighter spaces and do more groups shots so the wider angle of the 8mm is a real plus for me.

UPDATE: 3/18/19 - This lens works at 16mm on the K-1 without any issues from my tests. Must be at16mm, no other focal lengths are without problems, but then it essentially works as a 16mm fixed focal length lens on FF.

Really good. All marks out of ten for this type of lens (ultra wide zoom) as, naturally, it barrels.

Really nice handling - the internal focusing and (relatively) light weight makes this a potential walk-around lens when looking at cityscapes or architecture. Sharpness is really good for a lens of this price.

As others have remarked here it gives a good impression of having a polariser on the front. Colour rendition is notably more vivid than my 16-85 HD Pentax, which comes across as more 'neutral' and cool. But the colour rendering really works with the images that this lens produces.

A little gem!

Pros: Great colour & details for PS, Manageable size and weight, Unparalleled focal range
Cons: Great resolution not available at large apertures, construction not good enough

This is the second Sigma lens I have used on a Pentax body - around 3 years ago.

I bought it because I had wanted to have a try of the widest zoom AF lens - when I had never thought of entering K-1. This lens was rare in Hong Kong, so I bought mine from an Australian who delivered nothing less than described. On paper, it is not a particularly light lens. But thanks to the modern plastic of the lens body, it felt light to me.

I did not understand when others said it is not easy to compose when you use ultra-wide lenses - until I started shooting with it on Hong Kong Island - as you can see in my album of samples. This model is no doubt a great lens with great flare resistance, mild distortion, colour rendering just marginally inferior to DA 12-24 (my comparative impression according to samples). Still, it is uneasy to take impressive shots with a lens of this focal range.

It is a shame that I did not keep it for long despite its great performance - not to mention that I had tried using it with K-1 at 16mm after a little cropping!

Now I own FA 20-35 F4 as my only Wide Zoom for K-1, and several other respectable wide MF prime lenses. The 1st reason is that I prefer taking wide shots with distortion as little as possible. I am afraid it would have been the same issue with Sigma 12-24 for FF. Right now I have fun with prime lenses of focal lengths from 18mm to 25mm.

The 2nd reason is that using a ultra-wide zoom lens can be confusing. Even the zoom power is only 2x, you have to reconsider the composition from scratch every time after you change the focal length by 1mm. An equally important point is that ultra-wide shots rely on great sunlight much more than those at normal focal lengths. I had not learnt to be patient to take good photos yet. So you see.

The 3rd reason is that I found out I would not be into ultra-wide photography as much as I had guessed. So I sold this marvelous lens smoothly to a more committed photographer.

Similar to Sigma 50-500, it is a lens of its kind. I heard Sigma 10-20 is the best performer within the same era from Sigma. Still, this lens is good enough so long as you are not an extreme pixel-peeper. Right now, I prefer the rendering of Pentax (say, 24 3.5) and Carl Zeiss (25 2.8) prime lenses, so I am not looking back.

Since the release date of the new DA* 11-18 2.8 remains a mystery, together with DA 12-24, this lens should serve APS-C format lovers well enough.

I did not spend much time getting used to this gem so the samples should show far less than what it can do in great hands.

If you need a solid ultra wide angle you cannot do better on Pentax than with the Sigma 8-16. It is hard to find in the USA and expensive but nothing else does the job as well. There really is a difference between 8 and 10mm fl. which can be clearly seen in photographs. The only real negatives are the size (not actually that large and heavy but not as comfortable as DA 15 or DA 10-17 fisheye), and the price. Everyone interested in architecture, street scenes and wide vistas should give it

Pros: Well- Built, tack sharp @ center, reli nice color, shocking results
Cons: Really Strange barrel distortion when object is close, limitation on focusing

16mm



8mm


First thing first, if you really think a lens (or you) cannot live without a filter mounted on a lens, this is not a lens for you. Go for Sigma 10-20s , the DA 12-24 or Tamron 10-24......etc and you name it.

I cannot say this is there is a best uwa lens on the market now and it should not be. When it comes to this catagory, its all depends on what you asked for, there is no "best" ultra wide lens for "everyone". But i can say if this lens does not shock you, no other lens would. This is the one and the only lens offer 8mm focal length non Fisheye available now, and you would love the extra 2mm you can cover in your picture. If i have to put it in words to describe how wide is 8mm- its far beyond than what your eyes can see - Here is what happeend: I was sitting outside a coffee shop under a balcony. I can't see the top two floors of a 9- stroy building across from the street with my bare eyes, which the view is blocked by the balcony on top of me. But when i look thru the viewfinder with this lens mounted, i see the whole building with some sky- How Amazing

Pro: I got this from Adorama for $630 (GM price) and i think it worths the money. For the most part, it suprised me on the sharpness at any focal length even wide open ! (picture to follow) The picture also has very nice contrast and strong detail. This lens is built like a tank and comes with a useful soft case. Very friendly working distance, it even can focus as close as 25cm. I did not change lens on my camera for my last trip at all !!

Con: It's a known fact that this lens does not take any filter, if you already accepted the "physical property" of this lens then this is not a "con" at all. Right? read my first paragraph.
This lens does have a few weaknesses after some hands-on experience.
1. It is not a protrait lens and your eyes will not used it when you trying to take a protrait from this lens (when object is 3-4 ft away from u). The distortion is very pronounce especially when your object is human being. It is just a property of every wide angle lens. But when u hv the lens on ur hands, you just cant stop taking picture of people. It is fun if you like the result.

2. Auto Focusing is hit or miss for this lens in some occasion. Due to the nature of the wide-wide angle of view, your AF sensor will have a hard time to pick up small details in focus. I have tried to MF the lense using LV and zoom in as much as i can, and its still hard. Focusing is generally a non-issue for this kind of lens tho, for this lens you only need to(or only able to) focus the 1st 1- 3 Ft and after that is all infinity. DOF is very deep, this only happens when you are using larger aperture.

Conclusion:

You have to know what you need first before looking into this lens. If filter does matter to you then you should pick the other better options. It is a "either-or "question than the "good or bad" scenario when you comparing this lens with others that has the filter ability. The bottomline for this lens is really the ability to do 8mm with excellent picture IQ, i choose this lens because of this and i am very happy with the results.
