Sigma has patented a 70-300mm f/4-5.6 DG OS HSM lens, which is suggesting that the company is preparing to launch a successor to the existing generation.
Plenty of new optics have been patented since the beginning of 2016. For some reasons, it seems like companies are given more patent approvals in the early stages of a year, as Canon, Nikon, Sigma, and Olympus have all received the green light from the Japanese regulatory offices during the first three months of this year.
The latest unit to be patented is the Sigma 70-300mm f/4-5.6 DG OS HSM lens. It consists of a telephoto zoom optic that is designed for DSLR cameras with full-frame sensor and which comes packed with built-in optical image stabilization technology.
Sigma 70-300mm f/4-5.6 DG OS HSM lens patented in Japan
The most recent patent from Sigma is revolving around a telephoto zoom lens. The optic has a focal range between 70 and 300mm, so it offers a decent focal lengths for photographers who enjoy capturing action and sports imagery.
The maximum aperture of the lens is not the fastest on the market. However, it is decent, as it stands at f/4-5.6. The advantage is that the product features an image stabilization system, therefore it will minimize camera shakes in order to prevent photos from turning out blurry.
The patent application does not mention how many f-stops the IS technology offers, but at it should provide at least 3-stops, otherwise it would be pretty inefficient for today’s standards.
Sigma 70-300mm f/4-5.6 DG OS HSM lens also employs a HyperSonic Motor, which will deliver quick, smooth, and silent autofocusing.
New version will join either one of the Sports or Contemporary series
Sigma has filed for the patent back in August 2014. The exact date is August 26, which means that more than one and a half years have passed since the filing. Anyway, the approval was granted on April 4, 2016, so it is still too early to speak about a potential release date.
Whenever it comes, the new Sigma 70-300mm f/4-5.6 DG OS HSM lens will be added to the Sports or Contemporary series and will likely replace the existing 70-300mm f/4-5.6 DG APO Macro optic, which is available for Canon, Minolta / Sony, Pentax / Samsung, Nikon, and Sigma SLR cameras.
The new telephoto zoom optic features 21 elements in 15 groups and it is said to be quite effective in preventing aberrations, distortions, and other flaws from appearing in your photos.
Photokina 2016 is approaching, therefore we might see this product in the second half of 2016. Stay tuned for more Sigma rumors!
