Neat value for your coin: Sigma 100-400mm f/five-6.3 DG Os HSM Gimmicky
The Sigma 100-400 mm f/5-vi.3 DG OS HSM is a specially cheap super telephoto for the APS-C format. That does not mean that the epitome quality is likewise depression. At that place is zip wrong with the image quality. This is a lens from the Contemporary series. In contrast to Sigma’s Sport Serial, this lens doesn’t take a metal housing simply a plastic one. This not only ensures a lower price, but as well a lower weight. The Sigma 100-400 mm f/5-vi.3 DG Bone HSM is nicely portable. The weather resistance should too be slightly lower, but we exercise not immediately see where that difference should exist. The Sigma 100-400 mm f/5-half-dozen.3 DG Os HSM is namely fitted with a gasket on the mount. Compared to many other 100-400mm lenses, this lens is a fraction less bright. The 100-400 mms from, for example, Catechism and Sony accept a brightness of f/4-5.6. They do cost 3 to iv times as much. The most direct competitor is the 100-400 mm from Tamron, which is one third stop brighter at 100mm, but has the same effulgence at 400mm. The Tamron is well-nigh 300 euros more than expensive. A lens like this will non soon be used for portraits on APS-C. For that, the 100mm position is actually too much telephoto. On APS-C, it is much more of a lens for sports and nature photography and for telephoto shots where you lot want a dainty, flat perspective. At 400mm, you can isolate small details and get large subjects in the distance into the picture. This means you tin can accept different photos than with lenses with shorter focal lengths. The Sigma 100-400 mm f/v-half-dozen.3 DG Bone HSM Contemporary is available in Catechism, Nikon and Sigma mounts and tin besides exist used with Sigma’due south MC11 on Sony cameras with an E-mountain.
BUILD AND autofocus
The Sigma 100-400 mm f/5-vi.3 DG OS HSM Contemporary is compact. It is 182mm long, and the diameter is 86mm. The weight isn’t bad at 1160 grams. Merely the new Tamron 100-400 mm f/4.v-6.three is slightly lighter, although the difference is small-scale. The lens gets almost five centimeters longer when you lot zoom out. The optical design is comprised of 21 lens elements. 4 of these are made of special types of drinking glass. The body is fabricated of high-quality plastics. The lens should be slightly less robust than Sports versions, only information technology nevertheless feels very solid. This Sigma telephoto zoom even has a gasket on the back to foreclose the penetration of grit and moisture through the mountain. In that location is no play in the moving parts. The lens has a wide ring for zooming at the front end and a narrower ring for focusing closer to the trunk. In between, in that location is a lock to secure the zoom, and at the back is a whole range of switches for autofocus and epitome stabilization. The commencement switch is for autofocus, manual focus and MO, Manual Overdrive, a mode in which yous tin can use autofocus with manual corrections. Below that is a switch to limit the autofocus range, and below that, a switch for image stabilization. The bottom switch is for setting one or ii custom settings. These are programmable via Sigma’s USB Dock. With this, you can make a combination of various programmable settings such every bit autofocus speed, limiting or image stabilization. The Sigma 100-400 mm f/v-6.3 DG Os HSM Contemporary comes with a big plastic lens hood.
The prototype quality of the Sigma 100-400 mm f/five-6.3 DG OS HSM Contemporary shows a nicely fifty-fifty picture. At 100mm, the sharpness in the center is almost as high as over the rest of the range, but the sharpness drops off a bit toward the corners when you photograph a flat subject at a brusk distance. But if you don’t photograph a flat subject, you will detect fiddling of information technology in exercise. At 400mm, the lens is besides a little less not bad at full aperture, just the sharpness does amend when yous stop down one cease, both in the eye and in the corners. You rarely come across that with zoom lenses. Usually, they are significantly less potent at the longest position than at the other focal points. We prefer the feature of the Sigma. You volition buy a 100-400mm more for the 400mm mode than for the 100mm fashion.
The Sigma 100-400 mm f/five-half dozen.3 DG Os HSM Contemporary has ix rounded discontinuity blades, and the mistiness yous can go with information technology looks good. Bokeh balls have a fleck of a difficult edge, but within, they are pretty quiet. This give y’all a nice background blur, even if you have a busy background. Despite the low effulgence, thanks to the long focal length, you tin can yet create a cute background mistiness, especially if you naturally photograph at nearly the shortest altitude setting of 160 cm. The maximum magnification is 0.26x, and that is not macro, simply you can shoot small subjects with information technology beautifully. This lens has fiddling trouble with flare from backlighting.
VIGNETTING AND Baloney
This lens does not suffer much from vignetting. At almost, we measured vignetting of 0.6 EV at full aperture in RAW. That is a lot less when yous apply this lens on full frame. On APS-C, you naturally have the advantage that you only use the center of the image circle. In jpeg, this is even less thank you to the in-camera corrections, and, equally soon as you finish downwards one stop, it’s hardly relevant. Yous’re already at f/vi.3-8. We also run into the same difference betwixt full frame and APS-C in the distortion. On full frame, it can be clearly visible at the longer focal lengths, simply on APS-C, in that location is petty of it, with a maximum of just over 0.five% at 300mm in RAW.
Autofocus AND Image STABILIZATION
The Sigma 100-400 mm f/5-6.3 DG OS HSM Contemporary features Sigma’southward HSM motor with – co-ordinate to Sigma – a new autofocus algorithm. The autofocus works quietly and reasonably quickly, although it does not break whatever speed records. Via the USB Dock, you tin can adjust the speed and choose Standard or Fast. We did non have a USB-Dock for the exam. We accept therefore not been able to attempt the Fast mode, and nosotros do not know whether this results in reduced accurateness or non.
The image stabilization does its chore properly, and that is a must on the unstabilized SLR cameras from Nikon and Canon. A profit of two to three stops is easily doable, and if you lot do your all-time (and accept some extra shots), you tin get sharp shots even with slower shutter speeds.
