Leica 11-23mm VS Sigma 10-18mm comparison
Hello,
today a comparison between a new and already quite appreciated lens, and an older one of incredible performance.
I am talking about the APS-C Sigma 10-18mm f/2.8 lens and the APS-C Leica 11-23mm f/3.5-4 wide angle zoom lenses.
Both lenses are L mount, mounted on a Leica CL.
The main differences are size, weight and aperture.
The Sigma has a shorter zoom excursion but closer focusing distance and faster aperture. It is also lighter and shorter.
The Leica one has a longer zoom range, a slower and variable aperture but a higher image quality.
Size, side by side:
