- Brand: SIGMA - Model Name: Contemporary 16mm F1.4 DC DN - Compatible Mount: Sony E-mount - Lens Type: Single-focus, Wide-angle, Mirrorless, APS-C - Contents: Box, Front Lens Cap, Lens Hood, Rear Lens Cap, Instruction Manual, Warranty Thank you for viewing. I purchased this lens new and used it a few times for indoor video shooting, attached to a SONY α6400 fixed on a tripod. I am selling it because my job has changed and I no longer use it. It is in good condition with little signs of use, but please consider that it is a used item and make your judgment based on the photos. This is the first 24mm F1.4 equivalent (in 35mm format) lens for Sony E-mount APS-C mirrorless cameras. It is a high-performance wide-angle lens that combines a 16mm focal length with a bright F1.4 aperture. The lens has a good reputation, and I was personally very satisfied with it as it was a perfect match for my needs and I found it very useful. I recommend it to beginners as well.
