![]() ![]() This is far from ideal – I can hear the first car approaching and if I don’t find the screw soon, I’ll have no option but to gaffer tape the hood on. Without this screw, I have no way of securing the large metal lens hood to the front of the lens, and no way of protecting the huge front element from damage as stones and debris are flung towards me. The lens front is designed to ensure easy handling in such situations.Within moments of pulling the camera and lens out of my backpack, I’m on all fours, fingers searching through the mud, trying to find the tiny screw that dropped out of the lens hood as I loosened it ready to inverse and reattach it. This lens is optimised to allow the lens front to expand/contract smoothly in order to immediately adopt without adjusting the holding position, even to a sudden change in angle-of-view. Offering excellent usability as a straight zoom By attaching the supplied strap, the lens can be carried safely without putting unnecessary pressure on the mount of the camera. Socket is large and stable, it’s possible to click the position at every 90゜to make the change of shooting position from and to vertical and horizontal much easier. ![]() The tripod socket is newly designed since hyper-telephoto zoom lenses like this one which has 600mm telephoto-end often need a monopod or tripod for shooting. Newly designed tripod socket enables desirable fixing ![]() Using the optional SIGMA USB DOCK, it is possible to adjust the MO position’s sensitivity to switch to manual focus.

In addition to AF/MF, MO (Manual Override) is incorporated as one of the options of the focus mode switch. Manual override incorporated to make two full-time manual modes switchable. At the same time, the maintenance of the lens surface becomes easier. Water and oil-repellent coating ensures a pleasant photography experienceįorefront and rear lenses incorporate a water and oil-repellent coating that allows water to be wiped away easily and prevents oil and fat from sticking to the surface, even in challenging shooting conditions. It also helps during long exposure photography. It can be fixed at the photographer’s desirable focal length, which allows stable shooting whether the lens is positioned upward or downward. The new zoom lock switch enables the zoom ring to be locked at any focal length. Zoom lock switch can be set at any focal length It is able to meet the demands that professional photographers require in challenging shooting conditions, such as in the rain. The lens is Dust and splash-proof and designed for higher durability. This lens incorporates 2 FLD (“F” Low Dispersion) glass elements, which have performance equal to fluorite, and 3 SLD (Special Low Dispersion) glass elements, and compensates for colour aberration at the utmost.Ĭhromatic aberration in particular, which could be visible especially towards the telephoto-end even when stopped down, is corrected by the optimised design of glass elements including FLD lenses. Minimized chromatic aberration for higher optical performanceīy incorporating excellent optical glass elements, it minimises chromatic aberration and achieves class leading image quality.
