The Affordable Telephoto Zoom

Today, I am here to provide you with a video review of the new Sigma 100-400mm lens. This lens is designed for full-frame cameras, specifically mirrorless ones. It features an optical stabilizer built-in. What’s unique about this lens is that it has been ported from Sony e-mount full-frame to Fuji x-mount APS-C platform. This is the second lens I have seen being ported over, and it is interesting to see this trend happening. Both the Tamron 150-500mm and this Fuji 100-400mm lens are relatively compact for full-frame lenses. Despite being slightly slower in terms of aperture, the Sigma lens offers better optical performance and build quality compared to the Fuji lens. The most significant advantage of the Sigma lens is its price, which is nearly $900-$1000 cheaper than the Fuji lens. This makes it a compelling option for anyone looking for telephoto reach on their Fuji x-mount camera. In this review, we will examine whether this lens is worth considering for x-mount cameras.

Size and Weight

Coming to the APS-C platform, the focal length of the lens is affected by the crop factor. On Fuji, the 100-400mm lens is the equivalent of a 150-600mm lens on full-frame cameras. This focal range covers a wide range of telephoto opportunities and should be sufficient for most situations. Despite being designed for full-frame, the Sigma lens is actually more compact and lighter than the Fuji lens. It weighs 1135 grams (40 ounces), while the Fuji lens weighs 1375 grams (48 ounces). Even with the optional tripod collar, which adds 123 grams, the Sigma lens remains lighter than its Fuji counterpart. It also has a smaller filter thread size, measuring 67mm compared to Fuji’s 77mm.

Aperture Speed

While the Sigma lens is more compact, it is slightly slower in terms of aperture speed. It has a maximum aperture of F5, which increases to F5.6 at 113mm and further to F6.3 at the telephoto end. On the other hand, the Fuji lens has a maximum aperture of F4.5, which only reaches F5.6 at the telephoto end. However, the difference in brightness is minimal, as it is only a third of a stop. It is worth noting that the Sigma lens is not compatible with any teleconverters on Fuji, offering only the bare lens with no additional focal length.

Design and Functionality

The design of the lens is similar to the Sony version that was reviewed in 2020, with a few changes to the switches and buttons. Instead of an AF/MF switch, the Sigma lens has an AFL and AF switch, which are limited in functionality on the Fuji body compared to the Sony version. The AFL mode allows you to lock autofocus at a certain point or resume active autofocus by clicking the button again. The lens features a focus limiter and an optical stabilizer, which is now rated for five stops of stabilization. The feel of the switches on the Sigma lens is preferred over the Fuji lens, but the raised position of the switches may cause limitations in autofocus when carrying the lens on a strap.

Overall, the Sigma 100-400mm F5-6.3 DG DN OS lens offers a great value proposition for Fuji x-mount cameras. Despite being slower in terms of aperture, the lens delivers better optical performance, build quality, and offers cost savings compared to the Fuji equivalent. It is a compact and lightweight telephoto zoom lens that can satisfy most telephoto needs. The lens may have limited functionality on the Fuji body due to the lack of customization options, but it still provides excellent image stabilization. If you are in need of telephoto reach for your Fuji x-mount camera, the Sigma 100-400mm lens is definitely worth considering.
