#NIKON LENSES MANUAL#

This comes complete with the usual full-time manual override, and a focus distance scale mounted beneath a viewing panel. However, that should prove plenty for most shooting scenarios, and there are some serious plus points.Д¬ompared with Sigma and Tamron superzooms, the Nikon has a more up-market ring-type ultrasonic autofocus system. By comparison, the Nikon 18-200mm has a relatively limited overall range, equivalent to 27-300mm in full-frame terms. Indeed, Nikon, Sigma and Tamron all make 18-300mm lenses, while Tamron also markets 16-300mm and 18-400mm superzooms. When it comes to superzoom range, more might seem merrier.

You therefore donвЂ™t have to carry additional lenses, and neatly avoid the worry of muck getting into your camera when changing lenses in dusty environments. The main attraction of a superzoom lens is that it covers everything from wide-angle coverage to serious telephoto reach, without the need to swap the lens on your camera. Relatively limited zoom range -Pricey for an 18-200mm Relatively compact and lightweight, this Sigma has a variable yet fairly fast aperture rating and delivers impressive image quality, all at a bargain price. Great-value option: Sigma 17-70mm f/2.8-4 DC Macro OS HSM | C Sharpness drops off a little at the long end of the zoom range, while you can see some barrel distortion at the short end of the lens, but otherwise it's a great option. Focusing is swift and accurate thanks to ring-type ultrasonic autofocusing, while the VR (Vibration Reduction) stabilization system is very effective. It's also beautifully built, with no less than four ED (Extra-low Dispersion) elements, plus nano-structure coatings along with fluorine coatings on the front and rear elements. It's a great walkaround option with a flexible range and a wide maximum aperture that sees it well suited to a lot of different subjects. Typically bundled with higher-end cameras, such as the Nikon D500, this is the best DX format standard zoom lens. Image quality could be better -Relatively expensive
