Sigma announce 14mm f/1.8, 135mm f/1.8, 24-70mm f/2.8 ART

[Energize]

Thought I'd mention this as no one seems to have posted a thread on it (unless my search skills are lacking).

The 14mm will be fantastic for astro photographers and they are claiming 50MP resolution on the 135mm. No doubt these will be another three market leading lenses from Sigma that will steal away market share from Nikon and Canon and kick their arses into gear.

NEW SIGMA 14MM F1.8 DG HSM | ART LENS
The SIGMA Corporation is proud to announce the SIGMA 14mm F1.8 DG HSM | Art lens, the world’s first and only* F1.8 ultra-wide-angle lens

A true high-speed lens that delivers a new dimension of visual experience

In taking photographs of starry skies or other celestial scenes at night, or of the seashore with a wide perspective, a large-diameter lens is a strong ally, since it allows the capture of a moving subject by adjusting shutter speed without relying on ISO sensitivity. With its full-frame 35mm coverage, 14mm focal length for an ultra-wide angle of view, F2 barrier-breaking F1.8, the SIGMA 14mm F1.8 DG HSM | Art is the true high-speed ultra-wide-angle lens for which so many photographers have been waiting. Although some zoom lenses are available that can cover 14mm, the large diameter delivering F1.8 brightness is a singular advantage. Going beyond fast shutter speed, this lens can capture a swarm of fireflies with crystal clarity, a beautiful bokeh effect, and outstanding control of light streaking.

135mm telephoto lenses are often categorized as the foundational telephoto, the first one to add to a lens collection. This focal length delivers a strong perspective compression effect, while the large diameter with F1.8 brightness provides a dramatic bokeh effect. By minimizing axial chromatic aberration, the SIGMA 135mm F1.8 DG HSM | Art makes this bokeh effect not only impressive but also beautiful while delivering superb contrast and sharp image quality in every shot.

By incorporating its latest innovations in design and optical glass and rethinking every aspect of the lens, SIGMA has ensured outstanding image quality all the way to the edges, establishing the new standard in 135mm telephoto lenses.

With resolution so crystal-clear that individual hairs can be discerned in a portrait, this large-diameter lens also delivers a beautiful bokeh effect, giving photographers everything they need. It is ideal for close-ups and full-body shots, with subjects standing out against a pleasantly blurred background. In addition to standard portraits, including bridal shots, this lens is a top performer for live events, with its super-fast autofocus capturing subjects with ease.

What I don't understand is why more body manufacturers haven't put on sensor stabilisation into their cameras, that way all their lenses get stabilised without adding the bulk of IS optics to their lenses.

In lens stabilization results in increased cost, larger lenses and worse optics though, look at the cost and image quality difference in the old and new new Nikon 24-70 f/2.8! Manufactures need to think long and hard about adding IS systems to lenses, adding IS to sports lenses as some manufactures have done makes no sense.

Sensor based stabilization on the other hand has no downsides, is superior when there is lateral camera movement, and offers additional benefits such as auto horizon leveling that obviously lens based solutions can't offer.

Sony, Olympus, Panasonic and Pentax all have sensor stabilization, it's about time Nikon and Canon got into 2017.

There's no reason not to have the best of both worlds.
