Excellent Lens, slightly slow AF

The autofocus can be a little slow at times, but for the price and compared to the price of the G master, this is an excellent lens and I would recommend it to anyone looking for a good budget telephoto lens

Highly recommended - the Sigma 100-400mm for Sony is a great buy

Image quality is excellent in a relatively compact design. This will be a great outdoor lens for wildlife and nature photography. The image stabilization is pretty amazing, even at 400mm. Build quality is also a strong suit of Sigma lenses - this lens feels sturdy, well built. Overall I'm really loving it!

Tamron glass is awesome, and this bundle rocks!

An amazing lens and the bundle is great, very practical - I was going to purchase a UV haze filter anyway and cleaning cloths. No need with this bundle!

Pretty solid

Solid, premium build. Occasionally the autofocus isn?t ideal, but that may have more to do with my camera body, the Panasonic S5. Also it is annoying that it doesn't come with a collar. No complaints image quality-wise.

Good Replacement for expensive Sony lenses

The best replacement for the expensive Sony GM lenses. it's a good sharp lens, although the autofocusing is not the best of the best it does the job. If you are shooting many actions related photos you might have to reconsider the lens because of its slow autofocusing. this is a worthy lens in every aspect, it's worth the price you are paying.

Good lens but won't recommend

This lens looks well built, not that heavy either. 100-400mm range is quite good given the price tag. On the downside though, at max zoom the image stabilization is not great, I could get very few sharp images, that too in burst mode, not well suited for handheld shots. For quality image you need a tripod, and for that need to buy the tripod ring which is missing in the package here.

Great lens, regardless of cost.

For the money, this is a wonderful lens. If it cost a few hundred more it would still be wonderful, but I'm thankful the price is where it's at. AF is very quick and nearly silent. Length is great and hits a good spot for carrying around. I found this suitable for outdoor portraits, landscapes, wildlife and everything in between. It fits at the long end of my setup. I carry a Sony FE 1.8/50, a Sony FE 4/24-105 G OSS and this 100-400mm 1:5-6.3 DG DN. The OSS is incredible for such a long lens, enabling me to do some video at 400mm handheld! This is paired with my Sony A7rII.

Good lens but interesting extras

Overall, a good lens. I got this for my wife as a present. For the same price as just the lens, it includes the Coral editing software, filters, and a pouch. Lens works great and it fit the sony 6400 perfectly. However, it's been almost a month and we still have not received the filters and the pouch doesn't quit fit (see pics). Software hasn't been tried yet. Overall, recommend the product, just don't place too much value on the added accessories.

VERY sharp. Small and light enough for travel.

I had the Nikon version before switching to Sony. Both were VERY sharp. AF is fast enough. The lens is light enough to use handheld but sometimes a tripod is the way to go. The Sigma collar is stupid expensive. The Haoge LMR-SM140S is 1/3 the cost and work fine. I switched to Sony for travel and this is a good long lens solution for wildlife destinations when the trip isn't all about photography.

Good optics, so so AF

Very solid lens, and good optics but wasn't happy with the autofocus, especially for video. Perhaps I did not set it up correctly. I sent it back and was almost sad to do so because otherwise it felt good.

Lens is A-OK

So far the lens has performed well for me. That said, definitely make sure to purchase the tripod socket for it as well as it's a bit unwieldy by hand and too front-heavy to rely on a camera being the tripod attachment. I'm a warm-weather guy, so I haven't taken it out much yet, but the sample images I've tried so far, without a tripod, have been nice and crisp once I control my hand shake That said, bundle is so-so. The lens case didn't really fit the lens at all, so that was disappointing. The filters and other accessories are nice, though I don't think my use-cases will justify the other components.

Sigma 100-400 is a great Lens

This lens is a wonderful addition to my rig. It is very easy to carry, even though it weighs more than the camera body. One thing that is that it is missing the lens tripod mount, but that is available as an accessory. Focusing is very quick, and the stabilization is amazing. I highly recommend this lens for both full-frame and APS-C Sony cameras.

Great Lens Great Price

Great lens for wildlife, nature and landscapes. Amazingly enough I have been able to pull off some good enough portraits with this lens getting a nice compressed background within the variable apertures that it offers. It is perfect for the price vs a Sony G Master competing against this. I do not regret getting this lens at all, build is great, sealed and fairly premium. The only downside so far is finding a good enough lens collar that isn't as expensive as Sigma's. Yes, lens collar is sold separately, but still it is a great lens and stabilization mechanics really work well.

FEATURED REVIEWS

Push and pull zoom most underrated feature??

By BRENT D.

Great lens would definitely recommend....a surprisingly great feature push and pull zoom to keep lens hood from getting lost most people reverse it. One problem hard to get to the zoom ring problem solved push and pull to zoom works great. Would like the Sony 200-600mm I shoot a lot of birds...but size and cost could hurt. I use the cop mode and then I am shooting at 600mm sure the sensor becomes 10.3 mp but still great for an 11x14 or a little larger....could go on and on but will end with ...

Replacing my Sony SEL70300g

By TIM M.

It's bigger than I expected but its not a huge problem as its only like a half inch longer than my sony 70-300. I haven't had time to use it a whole lot but seems to get sharp and clear images. Autofocus seems to work better than my sony sel70300g which is what I'm replacing so I'm happy with the choice so far.

The Ultra-Telephoto Zoom That Goes Beyond The Ordinary.

The Sigma 100-400mm f5-6.3 DG DN OS is a Contemporary-series ultra-telephoto zoom lens with an equivalent angle of view at 150-600mm in 35mm format. It offers 16 groups and 22 elements with a 9-blade rounded diaphragm for beautiful bokeh and reduced ghosting and lens flare. Built-in image stabilization and impressive autofocus features, including an AF function setting switch for seamlessly transitioning between shots, will allow you to capture clear and sharp images. Weighing 2.5 pounds, the Sigma 100-400mm f5-6.3 DG DN is especially suitable for sports, nature, and event photography. Available for the Sony E mount, the Fujifilm X Mount and for L-Mount cameras.

Compact Packaging With Uncompromising Image Quality.

The lens construction of the SIGMA 100-400mm F5-6.3 DG DN OS | Contemporary comprises 16 groups and 22 elements, with one FLD and four SLDs used for the effective correction of aberrations and distortions. Built on the latest optical design technology and optimized for mirrorless systems, the lens ensures the same high-resolution image quality all the way to the edges. In addition, it constantly achieves high levels of optical performance and makes the most of its capabilities as a zoom lens in any condition, at every focal length from wide to telephoto, and from close-up shots to telephoto photography.

Compact Packaging With Uncompromising Image Quality.

Exclusive Low-Dispersion Glass.

The degree to which light is refracted by glass depends on the light's wavelength. This fact causes different colors of light to focus at slightly different points. The result is chromatic aberration, the color fringing that is particularly noticeable in telephoto lenses. Most chromatic aberration can be removed by combining a high-refractivity convex lens element with a low-refractivity concave element. Yet residual chromatic aberration known as “secondary spectrum” may still remain. To minimize this secondary spectrum, which can be a serious issue with conventional lenses, SIGMA lenses feature up to three types of exclusive low-dispersion glass offering superior performance: ELD (Extraordinary Low Dispersion), SLD (Special Low Dispersion) and FLD (“F” Low Dispersion).

Exclusive Low-Dispersion Glass.

Designed To Minimize Flare & Ghosting.

From the start of the design process, SIGMA measured flare and ghosting to establish an optical design that is resistant to strong incidental light sources such as backlight. At the prototyping stage, SIGMA used not only simulations but actual photographic experiments to assess flare and ghosting under multiple criteria, identify the causes of these issues under a wide range of situations, and take measures to mitigate them. In addition, SIGMA’s Super Multi-Layer Coating helps further reduce flare and ghosting and provide sharp, high-contrast images even in backlit conditions.

Push/Pull Zoom Mechanism Incorporated.

For quick control of the angle of view, the zoom ring incorporates a push/pull mechanism in addition to the regular twist mechanism. The exclusive lens hood has also been designed to accommodate push/pull zooming and overall lens maneuverability. By making it possible to adjust the angle of view instantly, this lens gives photographers an even better chance of getting that crucial shot.
