I only had a chance to shoot with the Sigma for a little over a day, but it’s definitely a worthy successor to the 30mm f/1.4 DC DN, if not even sharper. It reminds me of nothing less than the Leica Summilux 12mm f/1.4, my favorite vlogging lens for the longest time – until the Sigma 30mm f/1.4 unseated it. Two immediately noticeable improvements over the design of the 30mm are the lens hood and the focus ring. All you had to do was so much as look at the lens hood on the 30mm and it would fall off. The new one for the 16mm has been completely redesigned. The focus ring on the newer lens has more drag and will hopefully be easier to manually focus. I haven’t tested it yet, so stay tuned. Anyhow, apologies for the hastily put together video, I wanted to share it as quickly as I could. Incidentally, the good folks at Sigma must have been listening when I derided their 30mm for being so puny, so they rewarded us with a gargantuan lens that’s too heavy to fly on my Zhiyun Crane. hehe

Thank Jon, excellent video for what will be a definite purchase for landscape video. I can’t wait to see a lens sharper than the 30mm on my camera.
It is the manual focus I’m worry! I didn’t like my Sigma 30mm f1.4 in manual, mainly not good for video. I hope on the 16mm f1.4 will be a lot better!!
