Sigma 135mm f/1.8 DG OS Art lens to be announced in 2013

Sigma is working on two new lenses, which would make the cut into the “Art” series along with the recently-announced 18-35mm f/1.8 DC HSM zoom optic.

Sigma introduced the world’s first zoom lens with a constant aperture of f/1.8 on April 18, 2013 (or April 17, depending on the timezone).

Sigma 135mm f/1.8 DG OS Art lens may soon join the 18-35mm f/1.8 DC HSM Art lens on the market.

The optic has been critically acclaimed by photographers in the world, since it manages to keep a large aperture of f/1.8 throughout its zoom range. The product is a part of a series of lenses called Art.

We have heard through the grapevine that the Japan-based company is looking to extend its Art series with at least two new lenses by the end of 2013.

The first product to be unveiled and released on the market will be the 135mm f/1.8 DG OS Art, which will provide the same aperture of f/1.8 at 135mm fixed focal length. This optic is rumored to become available “sometime in 2013”.

Third “Art” lens in 2013 may be the Sigma 24mm f/1.4 DG optic

Sources will most likely dig up more details in the near future. However, another lens might be announced by then. It consists of the 24mm f/1.4 DG Art lens, which will not provide any kind of optical image stabilization, in spite of what the name of its bigger sibling is suggesting.

The Sigma 24mm f/1.4 DG Art lens is also rumored to be unveiled sometime in 2013, while its price, specs, and exact release date remain unknown for the time being.

Sigma might update the 50mm f/1.4 prime lens, too

The third and last lens which may make an official appearance in 2013, is an updated Sigma 50mm f/1.4 lens. This optic is currently available for Canon, Nikon, and Sigma cameras for a price of $449 at Amazon.

There are not too many units left in stock and it is unclear whether retailers will replenish the inventory or not.

Sigma 135mm f/1.8 DG OS Art and the 24mm f/1.4 DG Art lenses will be released for DSLR cameras with full frame image sensors, as the rumor mill does not have any information about more Sigma optics for APS-C cameras at the moment.
