![]() The optical path includes two ED (Extra-low Dispersion) elements, one aspherical ED element, and one Ultra ED element. As such, the size of the image sensor enables an even smaller, lighter construction, along with a 2x focal length multiplier that boosts the effective zoom range to a humungous 200-800mm.Ĭredentials include Leica backing, aspherical elements, and optical image stabilization, which can work in tandem with the in-body stabilizers of various MFT cameras. Like the Fujinon 100-400mm lens, this Panasonic is designed for crop-sensor cameras, but this time of the Micro Four Thirds variety. The Micro Four Thirds mount is used on Olympus, OM Systems cameras - and on some Panasonic and Blackmagic cameras too. Best lens for sport photography: Micro Four Thirds It’s a high-tech lens that’s ideal for both APS-C and full-frame Pentax DSLRs, but it’s pretty pricey and sharpness could be better, especially towards the long end. Sharpness drops off rather noticeably at the long end of the zoom range – a situation that isn’t helped by the lens’s reliance on in-camera stabilization. Other attractions include a tough, weather-sealed construction, HD coatings to reduce ghosting and flare, and a ‘super protect’ coating on the front element.Īutofocus speed is a little pedestrian compared with other lenses on test. There’s plentiful autofocus finery with both auto and manual priority ‘Quick Shift’ modes, plus an AF preset facility and four customizable buttons around the middle of the lens. ![]() The decision has come good with the subsequent launch of Pentax’s K-1 full-frame DSLRs. Pentax designed this full-frame compatible lens at a time when the company only made APS-C format DSLRs (where it gives an effective focal range of 230-690mm). See our full Sigma 150-600mm f/5-6.3 DG DN OS Sports review. This is an all-around excellent lens that's absolutely worth the money for E-mount and L-mount users. The build quality of the lens is also impressive – while no one is going to pretend this is a lightweight lens, it handles well, with tactile zoom and focus rings and a series of on-body controls for functions like AF speed, stabilization intensity, and in a new addition for the mirrorless version, Zoom Torque control to adjust the resistance of the zoom ring. The autofocus is excellent, though you'll need to make sure your camera is set up in the optimal way to take advantage of it. There's some inevitable fall-off in the corners, but not enough to worry about, and it's the sort of thing that will be hidden anyway when you're shooting with a shallow depth of field. The optical path is a little different from the DSLR version, including 25 elements arranged in 15 groups, and it produces impressive sharpness throughout the entirety of the zoom range. Of course, that wouldn't matter if the lens itself was no good. Pairing superb internal optics with an all-around excellent, weather-sealed build, this heavy-duty zoom lens is a big customer, but is really the only game in town for 150-600mm as far as users of the aforementioned mounts are concerned. A retooling of the already excellent DSLR lens, the Sigma 150-600mm f/5-6.3 DG DN OS Sports is the complete package for Sony and Leica L shooters.
