Sigma Corporation has created a collection of wide-aperture lenses through the years. While there are extra choices within the f1.4 vary, such because the 23mm f1.4, the 50mm f1.4 DG, and the 85mm f1.4, the quantity reduces a bit of with f1.2. However, it seems that the corporate is eager on increasing its vary, as a brand new patent has just lately been made public. How do they purpose to realize this? Let’s have a fast look.
First spotted by Asobinet, Sigma printed a brand new patent quantity, P2025124346, in August. The patent showcases six totally different designs for prime lenses: 35mm, 50mm, and 85mm with f1.2 or f1.4 apertures. While the patent was filed final yr, the corporate has launched the design this yr. Here’s a glance.
Filed on February 14, 2024, by Sigma Corporation, the applying outlines a design that balances compact dimension, diminished weight, and excessive optical efficiency. The system makes use of a floating focus mechanism with aspherical components, aiming to right points corresponding to distortion and focus respiratory—a shift in discipline of view that happens whereas refocusing, which is very distracting in video work.

The lenses are mentioned to stability compact dimension, diminished weight, and excessive optical efficiency. The floating focus mechanism with aspherical components is alleged to right distortion and focus respiratory. The lens can also be mentioned to assist individuals who shoot movies, because the management over distortion and focus respiratory may be useful.
As we mentioned, Sigma has two f1.2 lenses in its mirrorless vary: the 35mm f1.2 Art DG DN and the 50mm f1.2 Art. However, the problem with these lenses is their dimension and weight, which is quite a bit for an f1.2 lens. While new shiny aperture lenses may be useful, the query stays: Can Sigma redesign them for the higher? As the decision turns into larger, then lenses need to excel in capturing flare and sharpness.
Since there are already two lenses within the f1.2 vary, it stays to be seen whether or not the others might be in different classes, corresponding to Contemporary, which is more cost effective. However, it’s doable these are for analysis functions and should not grow to be a actuality quickly. Sigma has created some distinctive lenses, however they’re fairly enormous, which makes issues difficult. “The autofocus of the 35mm lenses on the market for the Sony E and Leica L systems, it’s probably the slowest,” as we mentioned in our assessment.
If the corporate fixes these shortcomings, they may definitely going to have a winner on their palms.
