The Sony FE 135mm is a full-frame, large aperture prime telephoto G Master lens delivering outstanding corner-to-corner resolution even at f/1.8 aperture. This pro lens includes dual front and rear XD linear motors to give fast, precise, quiet autofocus. It's also dust/moisture resistant and has a fluorine coated front element, so it's ideal for use in all weathers. XA and Super ED elements deliver high resolution XA (extreme aspherical), Super ED (extra-low dispersion) glass, and ED glass elements precisely deployed in an advanced optical design effectively correct aberration, while a floating focus system works with these aberration correction measures to ensure that the highest possible resolution is maintained right out to the image edges throughout the lens's focus range. Narrow depth of field The extremely high surface precision of XA elements, careful control of spherical aberration at both the design and the manufacturing stages, and an 11-blade circular aperture all come together to produce spectacularly smooth, elegant G Master bokeh that maximises the creative potential of the narrow depth of field available with this 135mm F1.8 lens. Dual front and rear XD linear motors achieve fast, precise, quiet AF Sonys innovative XD (extreme dynamic) linear motors also play an important role, making it possible to maintain focus on moving portrait subjects, performers on stage, or similarly dynamic subjects with impressive speed, precision, and reliability, while also providing AF control that is quiet and virtually free of vibration. Floating focus mechanism for improved close-up capability Although it is a 135-millimeter telephoto lens, a floating focus system that effectively controls aberration at all focusing distances has made it possible to achieve a minimum focus distance of just 0.7 metres and a maximum magnification of 0.25x for close-up photography. Small accessories and other subjects can be captured with remarkable resolution and soft, beautiful background bokeh. Mobility, operability, and reliability The important features include customisable focus hold buttons, a focus range limiter, an aperture ring with switchable click stops, a dust/moisture resistant design, and a fluorine coated front element. Overall, this is a lens that meets professional requirements for control and reliability for both stills and movies. | Sony FE 135mm f/1.8 GM Lens in Black. Free delivery on orders over £30
