Sigma 30mm f/1.4 MFT lens tested at Dpreview: “consistent performance across the frame for much less price than the competition”
Dpreview posted their full Sigma 30mm f/1.4 MFT lens test:
The Sigma ends up coming close or matching the Panasonic 25mm F1.4 ASPH in several parameters, even though it is slightly behind in center sharpness. For a lens that costs less than its competitor, it is a solid performance.
The Sigma can be ordered at Amazon, BHphoto, Adorama, WexUK, Jessops and Calumet Germany.
