Sigma 100-400mm f/five-6.three Contemporary Field Exam

Telephoto zoom lens delivers impressive performance and value

past Jeremy Gray | Posted 09/29/2017

Introduction

When it comes to loftier-powered zoom lenses, Sigma’due south 150-600mm Contemporary lens has proven to be very popular amongst photographers looking for a telephoto zoom lens that doesn’t intermission the banking company. Though smaller and more affordable than the 150-600mm Sport version, that lens still may be a niggling heavy or more than than they can afford. For photographers looking for a telephoto zoom lens that is compact and lightweight, a 70-300mm has often been a good choice, simply you do requite up a off-white bit of reach. Sigma’s new 100-400mm f/5-6.3 DG Os HSM Contemporary telephoto zoom lens hopes to split the difference and offering a powerful zoom lens that remains every bit easy on the arms as it is on the wallet.

Sigma 100-400mm Build Quality and Handling

Structure and Feel

The Sigma 100-400mm f/5-6.3 DG Bone HSM Contemporary lens takes on the same general look and experience as Sigma’due south other recent lenses, albeit without quite the same level of ruggedness and conditions sealing equally some of their more than expensive offerings. With that said, the lens does feel robust despite its lightweight pattern and offers dust and splash-proofing effectually the mount.

Sigma 100-400mm f/5-6.3 DG OS HSM Contemporary Review -- Product Image

In total, the 100-400mm is 7.2 inches long and 3.four inches in bore (182.3 millimeters x 86.4 millimeters), and information technology weighs 40.9 ounces (1,160 grams). The lens hood is only nether 3 inches long and extending the lens to 400mm does brand information technology about 2 and a one-half inches longer, so that’due south something to consider, only more often than not speaking, it’s pretty compact given its focal length range. Plus, it’south a full-frame lens, so its design is an even more than impressive achievement.

Looking at the rings on the Sigma 100-400mm lens, you’ll detect a large zoom ring toward the end of the barrel and a focus ring nearer the camera trunk. The zoom ring feels very nice and requires only a roughly ninety° rotation to go from minimum to maximum zoom, which is swell when needing to zoom in quickly. The zoom ring has a ridged rubberized surface that offers aplenty grip. Interestingly, the lens is besides designed for push/pull zooming, which is a breeze thanks to the special lens hood that has an indentation around its base of operations to help grip while you push and pull the zoom. Having both a “normal” twist zoom as well as the option for push/pull zoom is pretty unique and rather handy.

The focus ring offers a ridged surface but is plastic rather than rubber, which is fine for a ring that probable won’t run across a ton of use as most users volition probably stick to autofocus. The rotation has a good amount of resistance, and the lens has a windowed focus scale with many distance markings. The lens does have the choice for full-time manual override for focus, which is likewise a dainty feature.

Overall

Overall, the Sigma 100-400mm Contemporary lens feels very nice in the manus. Information technology’s compact and lightweight despite its impressive zoom range. It’s a breeze to use for extended periods of time and is a corking option for photographers who want zoom versatility but don’t want something big and heavy. The lens exhibits build quality across its toll tag, also.

Optical Quality

Optical Construction

Every bit is par for the grade when discussing a telephoto zoom lens, the Sigma 100-400mm f/5.0-six.three includes a complex optical formula. The lens includes 21 elements spread across 15 groups, including 4 Special Depression Dispersion (SLD) elements, which are designed to minimize chromatic aberrations. As we’ll see in a couple of sections, the SLD elements do their job quite nicely.

Sharpness

While I exclusively used the Sigma 100-400mm on my crop sensor Nikon D500 camera in the field, I did capture some exam images on a full-frame Nikon D800E to see how it performed, peculiarly across the unabridged frame.

When shooting at 100mm, the lens was a bit disappointing. It is not super sharp when shooting broad open, not even in the middle of the frame, and its corner operation wide open is non very impressive either.

When you stop the lens downwards, performance does improve, but information technology is still not very impressive in the corners. With that said, you likely aren’t purchasing a 100-400mm zoom lens to use it at 100mm, so how does the lens handle the critical 400mm focal length?

As we can encounter, when shooting broad open, the Sigma 100-400mm lens does quite well on the total-frame Nikon D800E. At that place is a skilful corporeality of detail present, and its performance is good for a telephoto zoom lens as meaty and affordable every bit the Sigma 100-400mm Contemporary.

At 400mm and at f/6.3 (wide open), the lens does okay in the corners. It’due south not superb and certainly not at the same level as the excellent Canon 100-400mm f/four.5-5.6L IS Ii zoom (which costs well over twice as much, I might add), merely it is very comparable to Nikon’south 200-500mm f/v.6E lens.

By stopping the lens down but to f/8, you are close to optimal performance with the Sigma 100-400mm, but at this indicate you’re pushing what is already a fairly ho-hum lens even slower. Speaking of making the lens slower, it is uniform with Sigma’s teleconverters, although I did not accept access to them.

These exam images are not perfect substitutes for lab images, just they are quite illustrative of what the lens can do at its two farthermost focal lengths. In my opinion, how the lens does with real earth subjects is more important. Can the Sigma 100-400mm f/5.0-6.iii DG OS HSM Gimmicky lens deliver images I’d be proud to share with people or print and hang on the wall?

Yes.

As you can see, the lens is capable of delivering enough of detail. Considering its price and versatility, I was impressed and pleasantly surprised by what the Sigma 100-400mm can practise given the right conditions (more on that later on).

Chromatic Abnormality

There is some chromatic abnormality nowadays despite the quartet of SLD elements, just it’due south nifty. There is some blueish/orange chromatic aberration, as you tin can see in the images below. It gets worse when looking at the corners of the frame and is non completely removed by stopping down. In real world situations, chromatic abnormality is not a big result. Information technology’ll be present only in particularly challenging scenarios and is rarely a big problem.

Vignetting

While there is some vignetting when using the lens wide open, even on the ingather-sensor D500, it’s very manageable and won’t pose many issues during real-world shooting. You can encounter some samples beneath, and information technology’due south articulate that the falloff decreases by stopping the lens down even simply a single cease at both focal length extremes. So if that’s an of import consideration for a specific image, stop down one or 2 stops.

Bokeh and Maximum Aperture

While the Sigma 100-400mm f/5.0-vi.three is not particularly fast with regards to its maximum apertures throughout its focal length range, information technology tin still produce pleasing bokeh given the right situation.

400mm (600mm equiv.), f/6.three, one/800s, ISO 2500.


When working from a shut distance, especially at 400mm, you can get dainty bokeh from the Sigma 100-400mm lens. The f/6.3 aperture at 400mm won’t offer nearly the same kind of subject separation you get from a faster lens, all else equal, simply it is still capable of creating a overnice telephoto look to your images with blurred backgrounds. And you have to pay a hefty premium for faster lenses at this kind of focal length.

I would similar to briefly discuss the lens’ maximum discontinuity throughout its focal length range. The lens goes from f/5.0 to f/v.3 correct effectually 120mm. The maximum aperture goes to f/five.6 around the 150mm mark. Well-nigh 220mm, the lens becomes a maximum f/6.0 optic and finally, information technology reaches f/half-dozen.3 at 350mm.

In the field with the Sigma 100-400mm

Autofocus

The HSM-equipped (hypersonic motor) Sigma 100-400mm zoom lens delivers pretty impressive autofocus functioning when paired with the Nikon D500. Granted, the D500 is one of the best focusing cameras I’ve used, so it’s a very practiced photographic camera to pair with the lens. Information technology is fast across its entire focal length range, although information technology is noticeably slower when shooting a very close subject at 400mm. Given its price bespeak, I was very impressed past the Sigma 100-400mm lens.

With that said, its maximum discontinuity can be a bit limiting when shooting in low lite, which is when wildlife photography is typically the best, so that’south something to keep in listen if you intend to utilise the lens for that purpose. Another aspect of the lens worth considering is that information technology will struggle a bit more than than a faster lens, all else equal, with shooting sports at night.

Shut Focus

The Sigma 100-400mm has a maximum magnification ratio of 1:3.8 (0.26x) thanks to its shut focus altitude of 63 inches (160 centimeters). On the DX Nikon D500, it performs fairly well every bit a pseudo-macro lens and focuses plenty close for basically all wildlife scenarios.

Sigma 100-400mm f/v-6.3 DG OS HSM Gimmicky – Product Overview

(From Sigma lens literature)
An ultra-telephoto lens with an optical stabilizer (Os) system has several advantages. The Os allows the photographer to take photographs in unstable circumstances. The narrow angle of view makes it possible to dramatically compress perspective and flexible handling of the background. The photographer can thereby make the subject announced to leap out of the epitome, with the area in focus impressively sharp and clear. Nevertheless, ultra-telephoto lenses take traditionally had some disadvantages every bit well. Equally the nickname “bazooka” implies, they have tended to be big, heavy, and therefore burdensome to conduct around. With the goal of creating an ultra-telephoto lens that is far more than attainable, SIGMA incorporated all of its latest technologies into SIGMA 100-400mm F5-6.three DG Os HSM | Contemporary. With its outstanding combination of optical operation and firmness, this is an ultra-telephoto lens that is a joy to behave and apply. While keeping the robust functionality and infrequent prototype quality of an ultra-telephoto zoom lens intact, SIGMA has achieved amazingly meaty packaging enclosing 400mm optics. Introducing the new and greatly enhanced “light bazooka” ultra-telephoto zoom lens.

SIGMA 100-400mm F5-half-dozen.3 DG Bone HSM | Contemporary offers the compact size, lightweight, and high price performance of a 70-300mm lens while delivering 400mm telephoto performance. This approach results in a tempting new ultra-telephoto choice for photographers. Offer a combination of stunning prototype quality and outstanding functionality, this lens satisfies the needs of pros and amateurs akin.

Key features

1. Top performance with the specification and functionality of a more expensive unit

Since its release, the SIGMA 150-600mm F5-6.3 DG OS HSM | Contemporary has won photographers over with its strong cardinal performance and exceptional image quality. The new lens retains all of this operation in a compact 400mm ultra-telephoto zoom package with a filter size of just 67mm and weight of simply one,160g. Still it also comes with the total range of features and functions expected of an ultra-telephoto zoom: optical stabilizer (Os), hypersonic motor (HSM) with updated algorithm for fast autofocus, focus limiter, and more. In add-on, this uncompromising specification becomes customizable with the available SIGMA USB Dock accessory.

2. Compact packaging with uncompromising image quality

In designing this lens, SIGMA strived to button both compactness and image quality to the limit. Four SLD (Special Depression Dispersion) glass lens elements and an optimized power distribution help minimize optical aberrations. Moreover, past taking special care to minimize transverse chromatic aberration, which cannot exist corrected via discontinuity control, SIGMA has ensured outstanding image quality throughout the zoom range.

3. Push/pull zoom machinery incorporated


For quick command of the angle of view, the zoom ring incorporates a push/pull mechanism in improver to the regular twist mechanism. The exclusive lens hood has as well been designed to accommodate push/pull zooming and overall lens maneuverability. By making it possible to adapt the bending of view instantly, this lens gives photographers an even meliorate chance of getting that crucial shot.

4. Telephoto plus macro functionality

With a minimum shooting distance of 160cm and a maximum magnification ratio of i:three.8, this lens can shoot either from a distance or upward close.

five. Other features

  • Dust- and splash-proof mount

    Since the area of the lens most vulnerable to dust and other strange bodies is the mount, rubber sealing helps provide peace of mind.
  • All-new optical stabilizer (Bone) unit with sectional algorithm

    Featuring a newly developed gyroscopic sensor and a new and exclusive algorithm, the all-new OS unit of measurement provides a powerful stabilization issue. An dispatch sensor detects camera milk shake in any direction-horizontal, vertical, or diagonal. This technology allows the OS to stabilize the image very effectively, regardless of whether the camera is being held in horizontal or vertical orientation.
  • Nikon electromagnetic diaphragm mechanism included

    The Nikon mount version of this lens includes an electromagnetic diaphragm mechanism that allows information technology to receive the advisable signals from the photographic camera body. This feature ensures precision diaphragm command and stable Auto Exposure (AE) functioning during continuous shooting. Note: Functionality may exist limited on some camera bodies.
  • Rounded diaphragm
  • Designed to minimize flare and ghosting
  • Compatible with the newly developed tele converters
  • Fast AF with full-time transmission focus

    Weight, size, cost, sharpness in the long finish, focus speed

    Sharpness in the wide end, lack of tripod pes, bokeh

    The 100-400 C is an ideal companion for travel, considering its compact size, its excellent sharpness in its long end, and its comparatively close focusing.

    The lack of a tripod human foot made me effigy out a solution of my own, using an Arca-Swiss-style plate (fabricated by Wimberley, about 7″ long), held in identify with a hose clamp (fairly loosely) and some Velcro every bit distancing packing, to avoid scratching the lens barrel. By adjusting the tightness I have full control over how smoothen the zoom works, with an infinite number of lock-up positions, should I need information technology. The other end of the plate is held in place by a screw into the camera’s tripod mount.

    This manner I tin go it to remainder perfectly, no matter if I attach a tiny Nikon one J5, or a full-grown FX body. I am taking it into the jungle on the Thai–Burma border soon, hoping to get some outstanding shots of birds, apes, or mammals (mayhap a leopard, jackal or elephant, who knows what we’ll come across).

    As other reviewers accept pointed out information technology is a bit hesitant in depression light, and the worse AF the camera has, the worse is the finish result, of course.

    The only other issue, bar the lack of a tripod foot, is the less than superb bokeh when used with the TC-1401 (the image sharpness is great with the TC, but the bokeh is a fleck ugly, so often it needs some post-processing).

    In practiced light with a DX trunk attached, I employ information technology with the TC-1401 all the time, and so the cease results are then not far what I become with the Sigma 150-600 S, except the bokeh issue mentioned above.

    For what it costs it is a pretty crawly lens, and it turns into a 1-meter focal length lens (35mm equivalent) when used with Nikon 1 body (and the FT1 adapter). Totally awesome.

    Information technology weighs a piffling over ane kilogram, thus is non heavier than most lxx-200 lenses, very compact, very affordable, and totally vice-less what more tin can you ask for?!

    Update, February 2020:

    The Bone is great for keeping the viewfinder steady, but non nigh as good as some other 100-400s!

    So to shoot birds it works best to utilise S and somewhere between 1/500 and ane/1000 for birds on the basis, and i/100-2,500 for flying birds. Not a doable combination in low light, sadly! For slow birds you might become away with 1/250.

    I have used mine a lot, the last half a year almost every twenty-four hours, and then information technology all of a sudden died, as I was switching from i camera to another. Total power failure! It does seem to attract grit (the frontwards end of the lens, thus not that critical), perhaps having something to do with the power failure.

    Permit’s hope for the all-time!

    Update, September, 2020:

    The power failure was solved by reinstalling the firmware.

    Still one of my most used lenses, and still one of the lenses I use with Nikon one, DX, and FX cameras, utterly delightful! Not the all-time in low calorie-free, every bit all reviewers have pointed out.

    November 2022:

    All the same going fine, and my ‘tripod foot’ is now slightly different: I utilize the same rail but the hose clamp is now replaced by a tightly knotted line, so as non to await then awful!

    Eventually, I took off the front element to go rid of the dust, which meant that I had to recalibrate the lens (the shims ended up in a slightly dissimilar position, I guess), and it now works perfectly, again.

    The disassembly is much like this Tamron: https://www.youtube.com/watch?v=e6mgeZbLsow

    Good optics, calorie-free and cheap

    Poor paradigm stabilization. Lack of tripod ring.

    I like my Sigma 150-600mm C and really wanted to purchase its smaller brother every bit a light weight for travelling and long hikes, and for my wife to use. I tested carefully four copies from my local dealer. 1 was a dud. The other 3 were optically excellent, at least as good equally my Catechism 100-400mm II. But they were all allow down past poor image stabilization, and I need practiced stabilization considering I heavily crop bird photographs, often taken at low shutter speeds. The lack of a tripod mount is a serious omission for me equally I carry the camera and lens on a strap while hiking and I don’t like using a single mounting point on the camera. Focussing is non nearly as fast as the Canon 100-400mm Ii. So, I’ll stick with the Canon as my lightest lens.

    *Very Sharp image. *Image stays sharp well into the corners without stopping down. *Compact size and low-cal weight (not bad travel size). *Fast AF when focal-length limited. *Great cost compared to comparable zooms

    *Epitome/optical stabilization (Os) is comparatively weak. *Little Bone feedback in viewfinder *Needs Sigma dock for optimal operation *With a f/6.3 max aperture at 400mm, it’s slower than other zooms

    First, if you desire this focal-length range in a compact body or for a sub-$1500 price, the Sigma is the simply game in town. And it has strong optical performance, and so you don’t take to sacrifice IQ to become into the game. Moreover, if yous want to use this as an action lens–which near 100-400mm are–so the and so-so Os should non be an issue. Just keep the shutter speed cranked up to 1/400 (preferably 1/thou) or faster and you’re competing in the major leagues. Too, if you focal-length limit the AF (either 0-6m or 6m-infinity), the AF is blazingly fast. It seems to be authentic as well, although i didn’t fully test it.

    Where you lot might have issues is when you lower the shutter speed below 1/400 and y’all’re taking photos of static objects. In these situations, the Os but isn’t as helpful equally that of the other systems. Admittedly I did not exam the panning Os type, Type 2, but I’grand not optimistic. Since the lens is on the slow side–max discontinuity is already f/five.six by 155mm and f/6 by 220mm–I found myself wanting to slow the shutter speed in too many situations.

    I hear that the dock addresses many of my concerns. Still, I’m a hobbyist, and when I buy equipment, I but want to use it, not dabble with customizations. If I didn’t have other options (I was hoping to supervene upon my Canon 100-400 L II lens and complete my transition to Nikon), I would probable keep this lens. Its size is a joy and makes it a near-perfect companion for travel. Together with its performance, cost, and high IQ, I recommend this lens but with caveats due to its Bone.

    Note: I tested the lens on DX cameras only (D7200 and d500). On FX (total frame) vignetting would likely be an issue.
