Panasonic Leica DG Vario-Elmarit 8-18mm f/2.8-4 ASPH Announcement

Sigma 24-70mm f/2.8 DG OS HSM Art is yet another Sigma lens presented today. This lens is certainly the most awaited one from the whole series presented today.
 
Sigma 24-70mm f/2.8 DG OS HSM Art has chances of becoming the most popular lens from Art series on the market for full-frame sensors. It is so because the focal range of 24-70mm works perfectly in almost every kind of reportage. What is more, this lens will also have an attractive price compared to the Nikon AF-S 24-70mm f/2.8E ED VR lens.

New Sigma 24-70mm has an optical system built on the basis of 19 lenses placed in 14 groups, where 4 elements are aspherical lenses, and three are made of low-dispersion glass, which is, according to the producer, going to positively influence image quality.
The front lens is covered with a special protective layer, which is to make cleaning easier and ensure that dust, water, and dirt will not easily rest on the lens. The lens will also have a stabilization system.

The new lens is also equipped with a quiet, ultrasonic HSM autofocus motor, which is to be 30% faster than its predecessor. The lens will also be compatible with the USB Dock personalizing device.

Unfortunately, the price and the date of appearing on the market, as in the case of other lenses having their premiere today, is not known yet.

Sigma 135mm f/1.8 DG HSM Art is yet another Sigma lens which is having its premiere today. This model is dedicated for the photographers specializing in portraits as well as street photographers. As the producer assures, the presented lens will guarantee high image sharpness already from the maximum aperture of f/1.8. Thanks to this, it will enable work even in very hard lighting conditions.

The lens consists of 13 lenses placed in 10 groups. Two of them are SLD lenses, and another two are FLD elements. Their role is to minimalize chromatic aberration.

As in the case of other lenses, the ultrasonic HSM motor will be responsible for adjusting focus. Apart from that, the AF drive doesn’t have classic mechanical connections – such a construction will enable the use of manual focus without a need to switch to the MF mode.
 

3). Sigma 135mm f/1.8 DG HSM Art
 
The lens is sealed, and compatible with the USB Dock station.
 

4). Sigma 135mm f/1.8 DG HSM Art with Sigma SD Quadro H
 
Sigma 135mm f/1.8 DG HSM Art will be available with the Canon, Nikon, and Sigma mounts. Thanks to an adapter, we will also be able to mount it to Sony cameras. As for now, the producer hasn’t revealed the new model’s price or the exact date of its appearance on the market.

It seems that people concerned with landscaping or architectural photography will soon have a possibility of buying a lens which have never been seen on the market before. Sigma 14mm f/1.8 DG HSM Art is the first lens which can take photos with an ultra-wide field of view and a f/1.8 lens at the same time. Additionally, the lens is designed to work with big full-frame sensors which are more and more frequently applied in today’s cameras.

Sigma 14 mm f/1.8 DG HSM Art can be also connected to the USB Dock docking station. Thanks to this, we will be able to upgrade its software.
