Sigma has released the 24mm f1.4 DG HSM lens as a member of its “Art” line of lenses. The previous Sigma Art lenses have been well received by the photography and filming community because of their good optical qualities at an affordable cost.
The Sigma Art 24mm f1.4 DG HSM lens has 15 elements in 11 groups. According to Sigma, there are three FLD elements and four Special Low Dispersion Elements to control chromatic aberrations. There are two aspherical elements as well for reduced distortions. Sigma claims that this lens will have good peripheral illumination and sharpness even at f1.4. A Super Multi coating will reduce the flare and ghosting and improve colour fidelity.
This HSM of this lens indicates Hyper Sonic motor which provides fast, smooth and near-silent autofocus performance. There is a full manual focus override function built in for finer manual focus control.
The 24mm f1.4 DG HSM Art lens has nine diaphragm blades to pleasing well rounded bokeh. One can use an optional Sigma USB dock to upgrade firmware in future.
The lens is constructed using a Thermally Stable Composite (TSC) material, along with traditional metals, for greater precision and use in wide temperature variations. So even when you are shooting in sub zero temperatures, this lens shouldn’t have issues due to contraction. The bayonet mount is constructed from brass for ensured accuracy and durability.
The outside of the lens barrel is also engraved with the year of production. This lens is available in Canon, Nikon and Sigma mounts and the mounts can be later changed by Sigma.
The minimum focusing distance is 9.84 inches or 25cm. This lens takes 77mm filters and weighs 665 gms. The price of $849 USD is attractive. The scheduled availability of this lens is March. One can preorder this lens at B&H by clicking here: http://www.bhphotovideo.com/c/buy/0/...990/KBID/13252
