New Sigma 17-70mm f/2.8-4 DC Macro OS HSM / DC Macro HSM lens inaugurates the company’s Contemporary line of lenses, which will become more numerous in the coming years.
Sigma has announced a new lens for DSLR cameras, which will provide a range between 25.5-105mm for a 35mm camera as it consts of a 17-70mm standard zoom lens designed for APS-C-sized image sensors.
The brand new Sigma 17-70mm f/2.8-4 DC Macro OS HSM / DC Macro HSM lens is touted to be perfect in most situations, including macro photography, so it should become a popular figure among travel photographers.
Introducing the Contemporary line of lenses
Sigma stated that the 17-70mm f/2.8-4 DC Macro OS HSM / DC Macro HSM is the first lens in the Contemporary line, now that the company is trying to organize its lenses into three segments: Art, Sports, and Contemporary.
The latest Sigma lens provides wide zoom range in a small and compact package, being about 30 percent smaller than Sigma’s regular models. The company is using a new material called Thermally Stable Composite, which supplies enhanced durability despite smaller scale rings.
Macro photography alongside telephoto
Sigma claims that the 17-70mm f/2.8-4 DC Macro OS HSM / DC Macro HSM lens has a 22cm minimum focusing distance at 17mm, while the amount decreases to 5.52cm at maximum focusing distance (70mm). There is no need to change the lens when taking close-up photos.
This lens has been optimized to the point where chromatic aberration has been dramatically reduced using a special power alignment technique. There is no image quality compromise within the entire zoom range, thanks to a huge maximum aperture of F2.8 at 17mm and F4 at 70mm.
OS and HSM
The 17-70mm f/2.8-4 DC Macro OS HSM / DC Macro HSM lens features an amazing optical stabilizer technology, which grants four-stop effective correction in order to improve the aforementioned macro photography technique. The drawback is that the Optical Stabilizer will not work in Sony and Pentax cameras, but it is supported by the rest.
Sigma’s improved Hyper Sonic Motor allows photographers to take photos faster, while the autofocus system does not make too much noise.
Sigma claims that 17-70mm f/2.8-4 DC Macro OS HSM / DC Macro HSM lens owners will be able to update the firmware through the new USB Dock and the Sigma Optimization Pro software.
