The rumour mill is running amok this evening that Sigma are developing an f1.8 135mm DG (full frame) OS (Optical Stabilised) Lens in their new ART rage of Pro level lenses.

Now if that is true, there would be some lovely goodness in an f1.8 lens.

Also Sigma are apparently going to be very aggressive in their lens releases in 2014 under their ART nomenclature. Sigma could well be looking to take on the manufacturers top end lenses. With the following line-up of new lenses being bandied about:


Sigma 24-105mm f/4 OS
Sigma 24-70mm f/2 OS HSM (Could be 2.8)
Sigma 300mm f/2.8 OS
Sigma 400mm f/2.8 OS
Sigma 500mm f/4 OS
Sigma 600mm f/4 OS
Sigma 135mm f/1.8 DG OS ART
Sigma 24mm f/1.4 DG ART
Sigma 50mm f/1.4 ART
