90mm f/2.8 DG DN Contemporary I Series Lens: Leica L
Mid Telephoto Prime for Leica L-mount
This Sigma 24mm f/2 DG DN Contemporary I Series lens is a portrait-length prime lens designed for the Leica -mount full frame mirrorless cameras. As part of the Contemporary line, this lens is designed with convenience and performance in mind while you are shooting portraiture and selective everyday shooting. Its fast f/2.8 aperture helps to control depth of field and working in dimmer conditions. Optically, an aspherical element and five Special Low Dispersion (SLD) elements are employed to correct axial chromatic aberration so that the imagery is sharp and more accurately rendered. Additionally, application of a Super Multi-Layer Coating helps to minimise ghosting and flare to improve colour fidelity and contrast.
The lens features a stepping motor to deliver fast and quiet autofocus performance that benefits both stills and video applications while an inner focus system increases stability, As an I Series lens, it is characterised by a sleek and stylish physical design, and features a newly designed arc-type auto/manual focus switch, a mechanical aperture ring and an all-metal barrel construction for enhanced tactility. Rubber sealing at the lens mount protects the mount from dust and water droplets. A nine-blade diaphragm provides for a pleasing bokeh.
This lens comes supplied with a lens cap, a rear cap, a magnetic metal lens cap and a petal lens hood. A separately available Sigma UD-11 USB Dock can be used to update the lens's firmware and fine-tune different different lens characteristics.
