I have a Pentax Kr DSLR and I bought this lens for wildlife photography to allow me to get a bit closer to shy seals, puffins and the like. This lens is absolutely brilliant, especially when you consider the price. The optical stabilisation works very well and the image is sharp even at the 500mm limit.

No hesitation in recommending this 'big' lens, it's probably a good idea to get an 86mm UV filter for protection as much as anything else though. 86mm is a big target for damage.

5 of 5 people found the following review helpful By Steve F on 5 Mar 2013
On the negative side it is a big heavy lens which, to be honest, at f6.3 at 500mm is not that fast. I found the lock button only works at the 150 end of the range so there can be a tendency for the lens to shorten when raised. (Note I also found that the autofocus does not work with the Samsung GX10 or Pentax K100 but is fine with my K5) Annoyingly even Sigma do not produce a teleconverter that works with this lens (some cheap ones may say they do but the resulting image is never really sharp on those I tried even with a tripod and remote release).
On the positive side if you are a Pentax user this is the longest lens you can reasonably get especially on a budget (Pentax now do a 560mm 5.6 but for £6000 and though Sigma advertise longer lenses suitable for Pentax I have found nowhere that actually sells them), the quality is good across the range, it focuses very close for such a long lens so it great for insects and the range is very useful for many kinds of wildlife. If you are a Pentax owner interested in taking pictures of wildlife this is the best (and realistically only) lens you can buy at present. Due to its weight the best results are via a tripod or hide clamp but it can be hand held and still give decent results.
Definitely a lens I have no regrets about buying but wish there were more options for Pentax owners.

Ordered Tuesday night, received Wednesday morning, now that's what I call fast... Read conflicting reviews about this lens and was unsure about buying it for a while, a great price yes but still a lot of money, for me anyway... After about 2 weeks of conflicting reports and reviews, I read a review from a guy, who has the same camera I do. Pentax K5. and it wasn't the same old number crunching, target shooting, confusing review you normally see, from someone using what they consider a great camera, which they tested it with.. No this guy just posted a series of photos, with details of how it was shot (settings) and then gave his verdict. I bought it on that review alone.. Now although I have not had a great deal of spare time, since it arrived to test it, I must say, I am very happy with the results so far.. Yes it takes a bit of practice to find optimum settings, for both lens and camera, like shutting of the OS, which drains your cameras battery and using the perfectly good Shake Reduction of the Pentax K5.. setting your camera to TAv and letting the camera decide on ISO, while you decide if shutter speed or aperture are the most important. .or full manual if your more adventurous.

I have also header many saying they shoot mostly hand held, I was sceptical of this too, considering it's weight. but that's where the cameras SR shines. and getting the correct settings for your situation. I gave it a go yesterday out in the fields, with some Red Kites and it performed above my expectations, also got some amazing shots of squirrels in the garden at the back of my house today.

If you are unsure about spending this kind of money, then let me just say this. I am no pro but I know quality when I see it and this, for what the pros would call "a budget lens" performs, in all aspects. It's sharp, well built, smooth and does the job of a super zoom, far better than I had expected.

Highly recommended

Very happy with this lens 28 Aug 2008
By JohnM - Published on Amazon.com
I am thrilled to have bought this lens to mount on my Nikon D80 after having read loads of reviews on the few options available like the Sigma 50-500 or the Nikon 135-400 and 80-400. I wanted the longest possible range below $1,500 in a recognizable Brand. I narrowed my choice to the 50-500 or this one. The Optical Stabilizer and the fact that Sigma had proven itself with the 50-500 were the determining factors in my decision. So far I shot some 200 pictures of various subjects at various distances handholding the camera with the OS turned on. Half way through my shots I reverted from full manual mode to Aperture control and noticed an improvement in the sharpness and colors which tells me that I need to hone my skills with this lens. So far, I am amazed at the quality of my shots with this huge glass. I take all my pictures with a -.7 exposure compensation as I like very vivid pictures and until I develop a better feel for what the lens can do I will continue to used it with Aperture control. The Autofocus is smooth, the overall feel is quality and the pictures are phenomenal for the distance. I look forward to plenty of fun with this lens, if you go for it you won't regret it.

UPDATE: In response to the person who rated this lens three stars I would like to quote David Bush's book "Nikon D80 Digital Field Guide" where he states "most lenses produce their sharpest image approximately two stops less than wide open. For example, if you're using a zoom lens with an f/4 maximum aperture, it probably has its best resolution and least distortion at roughly f/8". I've practiced David's suggestion with my Sigma 150-500 and it works beautifully, but like everything else, it takes some time to getting used to unless you're a professional photographer then you'd know this before hand. I added a few recent pictures shown above as part of this review.

I purchased my lens from B&H and it came in Sigma's black nylon zipped box which keeps the lens practically immobile. The box was very safely packaged when it arrived.

Great Lens! 4 July 2008
By But I'm feeling much better now... - Published on Amazon.com
Verified Purchase
I just received this lens and made a test shot I've made with other lenses. I took a shot of a satellite dish over a half a block away. Handheld. Magnifying it with Photoshop not only can I see the 'Dish Network' clearly, but magnifying a little more I can read the 'TM' underneath the logo. Clear as a bell.

This lens is a vast improvement over the 170-500 model. I used that lens on a wildlife trip and had to jack up the ISO to 800-1600 to get decent shutter speeds and a clear picture. Unfortunately that introduced noise, really bad in some shots. The D300 is much better than the D200 in that regard, but the lens was pretty much unusable without a tripod. This lens will alleviate any of those problems.

I usually buy Nikon lenses. This and the Sigma earlier models including the 170-500 (which I had to buy for a trip and now I'm selling) are the only lenses I could find that gave a substantial difference over the Nikon 70-300 VR. The Nikon 80-400 VR is $[...] and focuses slowly, and you can pretty much just crop to achieve the 100mm difference (I tried it to be sure.)

I'm looking forward to using this with a 1.4 teleconverter, you lose autofocus and 1 stop, can only go down to 100mm but get a 35mm equivalent of 1050mm! For only $[...]!

The quality of the lens is very good. There is zero zoom creep. Autofocusing is fast, though just a tad off (a few pixels off on the 'TM' - could be the camera, and that can be adjusted.) Manual focusing is tricky with the tripod collar on, it blocks the focusing ring so either move your hand to the top, slide your hand in between the lens and collar, or take the collar off. I got perfect focus using the viewfinder indicator as a reference point. The finish is of high quality, but a little strange. The whole lens including the hood is coated in some kind of flat black matte textured finish, makes me think of a stealth bomber.

I did a lot of research to find this lens, and was waiting for it since it's introduction 2 or more months ago. There is just no Nikon equivalent without buying a f/4 400mm with a TC-17 for about $5000 or so. If Nikon had a lens at 500-600mm for not too bad of a price hit I would have bought it. After playing with this lens just a little bit I'm glad I bought it. I'm fiercely loyal to Nikon, and it's arguably a better product, but I can afford to buy this lens 5 times over if it breaks, and it also saves the whole price of 2 photography workshops/tours.

There will probably be a lot of testing and comparing of this lens. None of that matters to me as it passed the satellite dish test with flying colors, I didn't even know the TM was there before today.

Edit 3/16/09 - I recently bought the Sigma 1.4 teleconverter to go with this lens. The 1st time I really used the combo was during the adding of the spire to the Trump Tower in Chicago. I was on the 7th floor of a building 1-1/2 miles away measured by Google Maps. I could see the men waiting in the spire for the next section to arrive. I had to back way off on the lens to get the tower and the helicopter lowering the sections into the frame. I lost autofocus, but it was no big deal to focus manually visually or with the in-focus indicator. Unfortunately I had to shoot through a dirty window, and it was pretty hazy, so the shots aren't that great but I don't blame the lens, the shots are better than anybody else got.

Edit 3/18/10 - Added Trump Tower picture to product images.

Happy Owner 12 Oct 2009

Essentially, the Sigma 150-500 OS is an indirect answer to the Canon 100-400mm F4 IS L lens. The problem with most comparisons is that the Canon F4 costs significantly more.

The direct point is that the Canon does perform marginally better in every aspect. The Sigma clearly wins in cost-performance ratio but that also varies based on your intended use and preferences. The main difference is the 70%+ price in the lenses.

The Sigma 150-500 is *NOT* a substitute for a low-light high speed use telephoto lens such as F2.8 lenses. However, the 2.8 lenses are an apples to oranges comparison - comparing a 400mm 2.8 that costs several times more ($6500) and suited to a different purpose. The Sigma lens is suited more towards daytime wildlife as opposed to sports events in varying conditions or poor lighting in any situation.

The 150-500 has shortcomings compared to the more expensive lenses - which is typically the case for any brand. I still highly recommend the lens & have enjoyed 600+ pictures within 7 days of owning it. The lens is excellent for wildlife, a great "out-of-box" experience with accessories, and will serve most a long time.

+ Optics are outstanding considering the market price.
+ Less than $1000 USD as of this writing
+ 500mm without use of a teleconverter
- Not as sharp compared to the 50-500 Sigma but the 50-500 lacks OS/IS
+ Light build quality considering lens class
- Durability trade-off for lower weight. Sealing not optimal, housing uses plastic.
+ Aesthetics. Rubberized/tactile feel with a sleek dark gray body.
- Aesthetics/durability. Coating on body prone to marks/scratches.
- Stiff zoom ring takes effort to operate.
+ Durable OEM lens hood included
+ Solid OEM hard lens case included (in fact it is shipped in the case)
+ OEM Tripod collar included
+ Excellent industry warranty (3 years USA)
+ HSM motor quick but not the fastest.
- Seeks a bit for focus in less-than-optimal light a bit earlier than the Canon equivalents.
- Autofocus a bit more finicky than lens-class equivalents.
- OS certainly does not reach the claimed 4 stop benefit
+ OS obtains a clear 2 stop advantage
- Noisy OS
- Image appears to shake a bit in viewfinder w/ OS operating

A final note: Most lenses (except prime non-zoom lenses) are a bit soft at the widest aperture (f/5) - this Sigma included. I certainly do not dock a non-prime lens for this as others have.

Updated 10-13-2009

I pushed several hundred more pictures through the lens and I am still satisfied. I will note a few observations including those not associated with the lens performance.

The Sigma feels a bit loose on my 450D/XSi when mounted. This is pronounced when adjusting the zoom ring which is rather stiff. Research indicates this is normal due to manufacturing tolerances, especially concerning the lens release/lock pin on the body mount. This issue varies depending on the camera body and lens - thus not a Sigma issue per say. An associate w/ the Canon 100-400 F/4 L IS lens reports similar behavior on his camera body (40D) but not on other camera bodies. I can't fault Sigma for this issue and I doubt everyone experiences this.

I mentioned a stiff zoom ring but I wasn't concerned with this initially. I thought the same about my Canon 24-70 F/2.8 L lens when I first received it. However, the stiff zoom ring coupled with the slight camera body shift seems to amplify the annoyance. Buyers should be very aware of the stiff zoom ring which I had not originally mentioned.

86mm filters are rather expensive. Tiffen offers a $30 UV filter solution but my experience is that Tiffen are poor quality products. Admittedly, I'm using one for the moment but have not noticed any reflections/aberrations. An 86mm Hoya UV filter runs almost $100 which I will purchase at a later date. I would not recommend a polarizer due to the loss of light.

I have gone through several camera bags - swapping and storing the lens in the field is a task. I am currently using the Lowepro Flipside 300 but that tends to be a snug fit w/ body attached. I will likely purchase a Lowepro Stealth Reporter D400 AW to carry my flash, 24-70 L lens, Sigma, and other necessities. The lens measures almost 9.5 inches in length.

Softness shooting wide open, OS is noisy 24 Dec 2008
By K. Seshadri - Published on Amazon.com
I was quite intrigued by the paper specifications and the other positive reviews. I used the lens on a Nikon D90 body and tried out some bird photography in late afternoon light. The lens build quality looks terrific and it has a very nice hood and case. Some of the problems I ran into were quality related and some just an artifact of a slow long lens. Auto-Focusing is reasonably fast. I got a lot of softness shooting the lens wide open (f6.3) at 500mm. You have to be very careful with focusing since the depth of field is extremely shallow (it's easy to misfocus on something ahead or behind the subject). The sharpness improved as I moved the aperture down to f/8 and smaller.

I also tried it with the OS (Optical Stabilization) Off (on a tripod) and On. For me personally, hand-holding below 1/200 seemed iffy. The OS was also very noisy and sounded unusual in that it was uneven. Further the unit continued to be noisy even after focus had been achieved and the shutter was half squeezed which I wasn't expecting. It takes a while to get used to the OS which seems to be different from Nikon. It takes a bit longer to kick in and you have to wait for this. This is probably something that takes a few days to pick up.

I've returned the lens since. I'm still intrigued enough to want to try out another one in case the problems I had were specific to the unit I had.

Bottom line, the lens build quality seems great and autofocusing is good. Expect some softness if you shoot wide open and long. You do have to make compromises getting a lens of this focal length at this price. The compromise is that most of your shooting will have to be on sunny days or with the ISO bumped up on cloudy days so you can shoot with smaller apertures and faster shutter speeds. Definitely worth a try.

Great value for money 3 Mar 2010
By Peter Gibb - Published on Amazon.com
I have now had this lens for about a month. I had read many reviews before purchasing it and so far the performance of the lens has exceeded or matched my expectations in every category.

I have used the lens a number of times mainly for bird photography - trying to capture birds in flight. Surprisingly the lens is not too bad to carry with you on a walk, and it is far better for hand-holding than I had expected. The Optical Stabilization is outstanding - I believe better than equivalent Canon tele-lenses that I have used. The only problem is that it is a a little noisy and slow. The key thing is that the OS makes hand-holding possible even for a 500 MM lens.

The build quality is good and both the focus and the zoom operate smoothly and for now have sufficient resistance to prevent lens creep. The plastic lens hood is a little cheap and sometimes difficult to mount, but at least Sigma gives you a lens hood!!!

Unlike other reviewers I have had no problems with the lens working with my Canon bodies.

Now for the downside - and I am unfairly comparing to Cannon Prime tele-lenses. Auto-focus is slower and less reliable than with the Canon lenses. When taking shots of birds in flight I guess that I miss a few more shots than I might with a Canon lens - but what can you expect for one quarter the price. At least I am able to even have an opportunity to get those shots on my budget. I just wish Sigma had included a focus range limit switch like Canon - this would be a vast improvement.

Lastly and most important, this lens has a softer focus than equivalent Canon lenses particulrly full open at 500MM. I have now resigned to try and shoot at an aperture of f/8 or less which improves the sharpness to acceptable levels. The sharpness is much better at less than 400 mm.

Bottom line I am able to take shots that I am extremely happy with on a long lens that I can afford. It has provided me with a tool to do bird photography. Sure compared to a Cannon prime, I probably miss a few more shots because of the slower focus, and sharpness may be slightly less. If you stop the lens down, the softness is difficult to see unless you do a full size pixel comparison.

The proof is in the pudding and I have been able to get some surprising good shots of bald eagles in flight with this lens. Would I buy a Canon prime instead of this lens if I could afford it - sure. Would I recommend this lens to a friend with a tight budget - absolutely without hesitation.

PS.

I have since heard that the build quality of these lenses may be variable. The example that I got may be an exceptionally good one.

Update after using the lens for three years

After using this lens for three years I have found that the focus is unacceptably soft with aperture wide open at 500 mm. This can be mitigated by stopping down to F/8 or even more and trying not to shoot over 400 or 420 mm. Focus is also slow so I have missed a lot of bird shot. Since posting I have upgrade to a Canon 7D and a Canon 400 mm f/5.6 l lens. The speed of focus and sharpness with the new set-up is very noticeable, however I still use the Sigma 150 - 500 mm as a walk about lens because of its versatility. I would still rank it is good value for money - just be aware that it is not as good as a Canon lens costing several times as much which I cannot afford.
