Sigma has just introduced new optics in London. Both the two Art models (35mm f/1.2 and 14-24mm f/2.8) and the Contemporary model 45mm f/2.8 will be released for Sony's full format E-Mount (FE) as well as for the L-Mount (Leica, Panasonic and Sigma full format).
These new models are remarkable in that they are the first Sigma lenses designed and developed specifically for mirrorless full-frame cameras. Previously, Sony's FE-Mount "only" rebuilt existing DSLR lens designs that were originally designed for a much larger focal distance. The new lenses, on the other hand, can benefit from a lower back focal distance, which is also to manifest itself in the low initial aperture (f1.2) of the new 35mm lens.
The 45 mm f/2.8 is relatively compact, has an autofocus and a minimum focus distance of 24cm.
The Sigma 45mm f/2.8
The 35mm type is the first autofocusing 35mm f/1.2 Prime for full format. It is supposed to have a resolution of up to 50 MP, a minimum focus distance of 30cm and, like the 14-24mm f/2.8, a particularly quiet autofocus hypersonic motor, which is excellent for video recording. It is also weatherproof and has an AFL button for additional control.
The Sigma 14-24mm f/2.8
None of the lenses have a built-in stabilizer, but all lenses have a manual aperture ring that can even be unlocked by a switch on the 35mm f/1.2.
The Sigma 35mm f/2.8
At first glance, the prices sound relatively high even for Sigma ratios. Thus 1599 euro are called for the two kind models. And 599 euro for the 45mm f2.8.
But just within the range of the so far available L-Mount optics such prices sound however nearly favorable. Here, for example, one currently still has to put 2,500 euros for a Panasonic Lumix S PRO 50mm f1.4 on the table.
By the way, the rumour mill had correctly predicted these lenses weeks ago and claimed that a 24-70mm f/2.8 for FE- and L-Mount is just around the corner. But while the 35mm and the 45mm are supposed to be in stores at the end of July and the 14-24mm at the end of August, this 24-70mm f/2.8 will only be announced at the beginning of the third quarter.
