Great Lens
By hp
Bought this from a NYC camera store and was delivered to me 11/11/13. I put myself on the wait list the minute it was announced so I am likely one of the first to get this lens. I have had only a few days worth of shooting but will put my initial impressions here.

Pros:

1. Superb optics. I am not a pixel peeper but no issues at any focal length even wide open. The lens is very sharp with fair contrast. No significant distortion. Slight CA. No noticeable vignetting in real life situations. I am not sure if my EM-5 is correcting for this lens with software. I have not tried on Panasonic bodies. All of this at a constant f2.8 throughout the zoom.

2. Size. No comparison to larger format lenses with a constant 2.8 aperture in this focal range. Others manufacturers might make FF and APS-C cameras smaller and smaller but they cannot match the size of the m4/3 lenses.

3. Very useful zoom range for the average shooter. This can be the one lens you can have for the entire system. It covers semi-wide to semi-long, good for landscapes to portraits. You might want to get prime lenses for bigger aperture, smaller size or shallower DOF/subject isolation but with the newer m4/3 cameras that do well at higher ISO, this lens is fine even for night-time photography.

4. Fantastic build quality. Olympus 75mm might be a tad better made but it is close. I should know; I own most primes from Olympus and Panasonic and a few zooms. I have tried almost every lens made for the m4/3 system from any manufacturer from friends. The lens is solid with good heft but not too heavy. It has good dampened rings which are as good as any m43 lens although inferior to lenses from Leica or older (pre-digital) lenses from Nikon, Canon, Olympus, etc.

5. Looks fantastic. I know it has nothing to do with picture quality but if I was not into visually pleasing things, I would not be into photography in the first place.

6. Lens button. I love the fact I can assign DOF to this.

7. Auto focus/Snap focus. It's as fast and as quiet as any m4/3 lens used on my EM-5. The snap focus feature by pulling the focus ring back is something that gives Olympus a significant advantage over other manufacturers. Brilliant.

8. Included hood and lens pouch. I thought h*ll would freeze over before this would happen. It is getting colder recently.

9. On that topic; weather sealed.

Cons: (Minor)

1. The lens is not fully retracted at 12mm. It is actually fully retracted at 16mm. Thus, if you store with lens at 12mm, the front element is not completely against the body. I am not sure if this will impact durability over time as it is carried/stored.

2. The lens cap is huge (for Olympus). They needed to redesign the lens cap due to the hood but I feel it is too thick now.

3. The lens crashed my EM-5. The camera crashed when I first attached this lens. I am not sure if Olympus will issue a firmware update. It was interesting to find out the power lever on the EM-5 is software based; i.e., flipping it did not turn off the camera when it crashed.

4. Made in China, like iphones, ipads and most other electronics. I was hoping for Made in Japan.

Overall, a great lens and highly recommended for anyone looking for an all-around lens for the m43 system.

This is not your average Zoom!
By NyArtboy
Honestly, what can I say about this lens that hasn't been already said? This lens has become for many reviewers and bloggers, either the Lens of the year or runner up. This lens has pro level IQ, amazingly fast AF and one of the most useful all around focal range for photography today. at 2x crop factor on m4/3 it behaves like a 24-80mm. It has nice bokeh and good DOF (Depth-of-field) at 35mm+ (70mm) and very sharp at 12mm (24mm) wide angle. Some sites have said that the 12mm f2 lens is slightly sharper but to me it's negligible. PLUS you get all this IQ and focal range in a weatherproof package! Pair that up with the OM-D EM-1 and you have an adventure waiting to happen!

Another question that pops up frequently on blog pages and review sites is the question between this and the high quality prime lenses out there for the m4/3 format. My opinion (just my 2 cents) is if you plan on shooting on nice bright days and don't want the hassle of changing lenses, then bottom line, this is your lens. On sunny/bright days you will end up stopping down the prime lenses anyway so you will get just the same amazing results especially if you pair this with an Olympus OM-D that adds in-body 5-point IS and Chromatic fixes in the software for this specific lens.

On the other hand, if you like to shoot in low light, have no problem switching lenses, and generally want the ability to achieve the maximum DOF (depth of field) you can get on the m/43 format than stick with primes. Though to be fair, the bokeh and DOF is perfectly fine for my taste on this lens at the higher focal lengths. Plus it has an amazingly short focusing distance so you can get pretty darn close to your subject which will increase the DOF as well.

If you are concerned with price, you shouldn't be. A lens of this quality at this price is an amazing deal. Here is my cost comparison/value break down:

If you bought the 12mm F2 and 45mm F1.8 you would be $200 above the cost of this lens (all brand new) and only have 2 focal lengths.
The equivalent price in primes would be the 17mm f1.8 and the 45mm f1.8 but you lose the nice wide angle 12mm focal length and gain possibly the "best portrait lens" for m4/3 cameras with nice creamy bokeh and sharp IQ.
To me the ideal prime set is the 12mm f2, 25mm f1.4 (Panasonic) and 45mm f1.8 which puts you at roughly $1800 give or take.
A nice f2.8 combo would be this lens (12-40mm f2.8 Pro) and the 60mm f2.8 macro giving you a fully capable system of varied focal lengths plus macro and medium telephoto capabilities all for about $1400.

Pros:
Extremely Sharp IQ corner to corner
Super-fast AF (I think faster then my L series lens tbh)
The best and most versatile focal lengths for everyday photography
Ability to get very close to subjects. Just a few inches in fact
Large Aperture for decent bokeh and DOF
Weather-proof!
All metal construction
MF 'choke' design for quick switching to Manual Focus mode
Includes a customizable L-FN button on lens for additional functionality.

Cons:
Big and somewhat heavy (though half the size of lets say the Canon 24-70mm f.28 L) - The size doesn't bother me in the least I have to add. Makes the E-M1 look pretty awesome.
Tube Extends during Zooming (would have liked the elements to stay within the lens, thought this would probably double the price)
Not the smoothest zoom and focus ring on the market. The other primes I have are way smoother. In fact there is small 'tap-like vibrations' when zooming. After speaking with Olympus directly they informed me this is normal operation.
Loses almost 2 stops compared to the primes available today for m4/3 format cameras.

I'm happy to answer questions posted here in Amazon. Good luck!

Outstanding lens
By M. Gotts
I've owned Olympus' OM-D E-M5 camera body since Christmas 2012. Using the kit 12-50mm and the 40-150mm (24-100mm and 80-300mm 35mm equivalent) lenses I've had a fun year capturing photos. The camera has been everything I wanted it to be, with the exception of being just average tracking kids playing soccer.

But the 12-40mm f/2.8 lens takes the camera to a different level. I thought I was getting decent performance from the 12-50mm lens -- and I thought wrong. It's okay, for what it is, but it's slow (f/6.3 at 50mm) and just average in sharpness. With nothing to compare to, I didn't realize how it was holding back the E-M5's potential.

The 12-40 is truly top caliber. Sharp from corner to corner. Chromatic aberration cannot be found. Fast for extending the E-M5's low light capabilities at modest ISOs (I can gain nearly three stops from the 12-50mm in many situations). On the PC I'll zoom in on shots and be astonished by the crispness that simply didn't exist before.

Having never owned an expensive DSLR (I had a decent Nikon FE2 film body and some Vivitar Series I lenses in the 80's, however), I'd been lulled into thinking the images I was capturing were simply all that such a camera was capable of. The E-M5 is a very good micro four thirds body, after only the new E-M1. What difference could one lens make? Well, as it turns out, a great deal.

The 12-50mm has a smooth motor drive mode for video (which I rarely shoot) and a dedicated macro mode, which is nice. But the 12-40mm, while not being optimized for macro, turns out to be a fully capable macro lens as well, better than the 12-50, IMHO, because of its superior resolution and significantly faster performance and ability to isolate at f/2.8. The only step up for close up photography being to a dedicated macro lens. (And yes, I know that with regards to depth of field it is twice that of a full frame sensor. But f-stop is dimensionless, and with regards to light-gathering-per-sensor-size/exposure/ISO, f/2.8 is f/2.8 is f/2.8, whether it be APS, M43, full frame or a large format camera.)

The only thing I don't like is the price. $1,000 was a big chunk. But the way it has changed the performance of the E-M5 is truly revelatory. There really is a significant optical difference between a decent mainstream consumer lens and a pro level lens. The 12-40 lives on my camera now, and the 12-50 is going to end up on eBay.

If you've got the E-M5 or M1 and can afford it, this lens is a no brainer and will not dissappoint. Since the long end is only 80mm equivalent, I think even Lumix body owners can enjoy it's benefits despite not having the in-camera stabilization that Olympus bodies have.

Nice lens in the right hands! Nikon 10-24mm f/3.5-4.5G ED AF-S DX
By Webtrance
Upon first inspection, fit & finish are on par with Nikon's own 18-200, 16-85, etc. I would say that it's very-very close to the build, size/weight of my 16-85. It's a very decent build, solid plastic, and has smooth operating zoom and focus rings. This lens has a metal mount, weather seal gasket, and a focus distance window.

Why I didn't buy the 12-24 f/4: The Nikon 10-24mm will give me 10mm at f/3.5, which works fine for me. The 12-24mm will give me 12mm at f/4, which is neither wide or bright enough. I hear so many folks state "but the 12-24 is a constant f/4." I've also heard people say that "variable aperture" lenses are indicative of cheaper or consumer-grade lenses. I don't necessarily agree with that. I believe most lenses are a touch sharper when stopped down from their maximum aperture anyway, therefore a constant f/4 with the 12-24mm doesn't necessarily attract me to that lens. I wouldn't shoot the 12-24mm at f/4 anyway, especially for landscapes. In my opinion, the 10-24mm makes more sense with it's wider field of view.

I choose the Nikon 10-24mm for the following reasons:

1. Versatility. This is one of its best attributes. The 10-24mm is versatile due to ultra wide views for landscapes, yet can zoom to a more natural focal length for a quick snapshot or portrait at your home gathering or outing.

2. Landscape photography. For me, it comes down to real-world applications and benefits of having a wide angle. I love landscape shots and though you can make decent landscapes at 18mm, having an ultra wide in your bag allows you to capture expansive vistas, whether at the beach or the mountains.

3. Perspective. The perspective you're able to get with this lens is tremendous. Though there is fair distortion on the 10mm side, it's easily correctable with DxO or Photoshop, among other graphics programs. To be creative with wide angle, read Ken Rockwell's page on using a wide angle lens. He and others will explain that a wide angle is for drawing people into the picture. Use your wide angle to emphasize the main subject. As Ken says, ultra wide lenses are for getting close and bringing the viewer into the photo, not for fitting a subject into a photo.

4. Range. Opting for the Nikon 10-24mm gives more range than both the Tokina 11-16mm and Sigma 10-20mm. It can easily be left on the camera all day, allowing landscape shooting and a decent portrait lens from 18-24mm without the need to switch lenses.

So how's the lens? It's outstanding, given the nature of ultra-wides. You'll notice distortion in the far corners/sides of your images below 15mm or so. Those corners will be a little soft at times, depending on your aperture setting. Wide open at f/3.5, you'll get softness away from the center of the image. Depending on your shooting habits, the large aperture will not detract from your images if you place your main subject in the center. Even wide open the main subject or center of the image will be sharp. Stopping down to f/5.6, f/8, and smaller apertures sharpens entire image. For landscapes, I routinely shoot at f/5.6-f/11 or smaller for optimal sharpness across the entire image.

Alternatives to Nikon:

A. Tokina 11-16mm. In my opinion the 11-16 at f/2.8, though a fine lens, is not necessarily a landscape lens. I don't shoot landscapes at f/2.8, f/3.5, or f/4 for that matter. If I want captivating ultra-wide shots with foreground/background in clear focus, I'd set f/5.6 through f/16 or beyond, depending on the lens I'm using. This is not to say you can't bring the Tokina to the Grand Canyon and shoot at f/11 to capture an expansive view at 11mm. You can surely do that with the Tokina, but you can see where I'm going with this. The Tokina's maximum aperture of f/2.8 is not utilized when shooting in a landscape setting. The Tokina makes for a superb low light interior ultra-wide, whereas it's hard to use a flash and light the entire room properly. I believe that lens serves a different purpose all together and you may find the zoom range too limited.

B. Tokina 12-24mm. It's definitely a contender at half the price. Superb build - better than Nikon. However, wouldn't you rather have Nikon for the ultimate in quality, dependability, and resale value?

C. Sigma 10-20mm. It's worth looking at due to fair reviews, better range than the Tokina 11-16mm and its low price point compared to Nikon.

D. Tamron 10-24mm. I wouldn't write it off completely. However the reviews I've read do indicate it's too soft, so and check the user reviews and Ken Rockwell's review as well.

The filter for this lens is a 77mm. I opted for a B&W multi-coated UV filter. B+W 77mm UVA (Ultra Violet) Haze MRC Filter #010 Filters in this size can be pricey, especially a 77mm circular polarizer, which isn't recommended for this lens due to uneven darkening of skies. You'd be better off grabbing a Cokin Z or for UWA lenses, the X-Pro series filter. The Lee foundation kit utilizing 4x6 filters or Hitech's 4x5's would be a good option.

Neutral Density (ND) Filters. Many of you may wish to make cool wide angle shots of a waterfalls, creeks, rivers, or oceans with the silky smooth water movement you see so often in these pictures. To do that you need a neutral density filter if shooting in daylight conditions. I would recommend an inexpensive Hoya 77mm ND8X. Hoya HMC NDx8 - Filter - neutral density 8x - 77 mm If you're worried about vignetting with the Hoya, please don't. I use it on the Nikon 10-24mm and see absolutely no vignetting at 10mm. The ND8x is a 3 stop filter and will allow you to get between 1-2 second shutter speeds during broad daylight. With those speeds and by using a tripod, you're able to get the silky water movement in your waterfalls and such. Better still would be to wait until later in the evening or find a shaded cove or dense foliage location with a waterfall or creek. Your shutter speeds in those conditions may be upwards to 5-6 sec or more.

Circular Polarizer's (CPL): Not recommended for UWA lenses due to uneven darkening of skies. However, I carefully and strategically use a 77mm Marumi Super CPL with no issues with uneven darkening and no vignetting. The Marumi is fantastic with a solid 5mm thin build, superb polarization quality, and smooth operation. It's almost equivalent to B&W's top end CPL and less than half the price. What I mean by strategic use of a CPL is to use clouds, trees, buildings, etc, to "mask" any uneven darkening of skies. Moreover, you don't have to use your CPL with its maximum effect. It works very well at giving you a touch more blue in your skies, while helping to bring out details is clouds and brighten & saturate your foregrounds. On cloudy days, the CPL can help you with your reflections, so it's not only good for those sunny days. I would avoid using it for landscapes with clear blue skies that fill the frame. If you are to do that, you'll clearly see a dark striation down the center of your image. The CPL effect can't cover the field of view at 10mm and there's no getting around it, less "masking" your shot with clouds, trees or buildings as mentioned earlier. Marumi CPL is here: Marumi DHG Super Circular Polarizer CPL PL.D 77 77mm Filter Japan By the way, I can stack the Marumi and the Hoya ND8x down to 11mm with no vignetting.

Regarding my copy of the 10-24mm, with thourough testing, 10mm seems sharpest at f/5.6 - f/8. Depth of field appears as broad at 10mm f/5.6-f/8 as it is at smaller apertures. At 24mm, my sharpest setting is f/11.

Bottom line: The Nikon 10-24mm is a superb ultra wide lens for DX cameras. Its build quality is typical Nikon with a solid plastic feel, smooth zoom & focus, weather sealed gasket, metal mount, and quick/quiet auto focus. It's capable of sharp landscape pictures and offers any photographer the ability to take creative pictures with tremendous perspective and depth.

Excellent on DX and works on FX too
By Doctor.Generosity
Another work of Nikon lens genius which gives the ability to take dramatic, unusual, never-before-available, super-wide pix. As recently as a few years ago, before Nikon learned to mass produce aspheric elements, manufacturing this complex 14 element lens at reasonable cost would have been impossible. Compared to the earlier 12-24mm, significantly wider angle.

A nice suprise is that this DX lens can also be used FX, with some limitations of course. Although it will give the full zoom range only when used on the smaller DX format, it actually covers the frame of an FX camera - not over the full range but from 24mm down to about 18mm focal length, with acceptable vignetting (edge darkening). I am using it that way on my film Nikon F6 and digital D700. (For the D700, turn the DX Crop default OFF and turn the Vignette Control to HIGH.) This is pretty cool because it means that someone who wants only occasional use of an 18-24mm lens on a full frame camera does not have to go out and buy a new lens if they already have this one.

I disagree with the reviewers who complain about the plastic, Made in China construction. If this lens were made of brass and steel like a Leica, it would weigh twice as much, cost much more, and be no better photographically. Is it more important to have the controls be smooth than to capture new kinds of photos? In my opinion Nikon has taken the right approach - state of the art computational design, innovative manufacturing of aspheric elements, good enough construction, and breakthrough capability affordable for the amateur photog.

Soft in the corners
By GroovyGeek
I have owned and shot with the Nikon 12-24, Tokina 12-24, and three copies of the Sigma 10-20. With the exception of one recent bad copy of the Sigma they were all notably better than the 10-24 in the corners. My copy of the 10-24 is nice in the center, but all four corners were uniformly degraded. Every other WA lens I have owned cleans up very fast in the corners at 10-12mm and by f/5.6 was nearly as good as f/11. Not so with 10-24, which is mushy in the corners at f/3.5 and improves only gradually as it is stopped down, with peak sharpness at a bit over f/11. At f/11 it mostly catches up with the third-party lenses mentioned above and Nikon's own 12-24. I have posted sample images on DPR, photo.net, [...], look them up to see what I am talking about.

The 10-24 range is ideal for my needs so it is a shame that the performance is not as good as the 12-24, even at 12-14mm. The MTF numbers would have suggested that it would be better. My copy is not. Since all four corners are nearly uniformly degraded I don't think that I have a lemon, it may be just inherent in the lens design. I am tempted to call it curvature of field, but with the extreme DOF at 10mm even at f/5.6 I am not sure this would be a reasonable explanation.

While not as terrible as the sample images I have seen from the Tamron 10-24mm, my copy of this lens would not seem to be as good with flat-field subjects (aka brick walls :-) as the other WA lenses I have owned. However, in real-life images with variable depth the corner softness is very difficult to see. Not sure if this is because of the possible field curvature mentioned above, or because it is very rare that I shoot something that has good detail all the way to the corners.

Overall I am a bit disappointed. Given the price it should have been unambiguously better than the competition. Not 2x better as other reviewers have suggested, I am prepared to pay a decent premium to Nikon just for the consistency of color rendition I would get between this and my other most used lens (70-200). However, my expectation was to be able to say "about the same as the Sigma 10-20 in most respects, better at X and Y". Right now I am not sure what X and Y would be, at least in comparison to the excellent copy of the Sigma 10-20 I used to have.

I will probably end up keeping the lens. The 10-24mm range is just too convenient for me, and there is no way I would consider replacing this with the Tamron 10-24, which is absolutely terrible in the corners at 10mm according to numerous reviews.

===========================
Update on 1/7

I need to amend the review. I am leaving the original text unchanged for reference purposes, so it is clear what I said earlier and how my views have evolved.

After using the lens for a few months I need to retract my "soft in the corners" assessment. Not sure how I came to this conclusion with the original tests, the softness was clearly there, but try as I might I cannot reproduce it now with careful focusing. My best guess is that I slightly mis-focused, AF can be unreliable on WA lenses. If you test it against a brick wall make sure to be square and use LiveView with manual focusing. With careful focusing the lens is at least as good as the Sigma 10-20 that I loved so much. Not corner-corner sharpness, that would be a small miracle at 10mm, but slightly better than anything I have seen from the competition. Overall the lens is still not a great value for the quality delivered, but if price is a secondary concern you will love the range and consistency of color rendition with your other Nikon lenses. If you want the absolute best bang for the buck go for the Sigma, just make sure you test it carefully, there are many documented instances of significant copy variation. The colors a slightly different, not better or worse, just different.
