It delivers good performance wide open (around 3,600 lines) on the a7R IV's demanding sensor.
SIGMA 35MM 1.4 SOFTWARE
I paired the 35mm F1.4 DG DN Art with the 60MP Sony a7R IV for testing, and used Imatest software to check its resolution. Budget shoppers can turn to the Tamron 35mm F2.8, only available in E-mount-it nets 1:2 macro results and is a bargain at around $200. If you use a Sony camera, you can look to the high-end Sony FE 35mm F1.4 GM for closer focus, to 9.8 inches for 1:3.8 results.
It's in line with some direct competitors-the Sigma 35mm F2 Contemporary and F1.2 Art just about match it, and are available for both E- and L-mount cameras. The view gets a little tighter when focusing up close, netting 1:5.4 magnification at the nearest 11.8-inch focus distance. For still imaging, the flexible response can come in handy-but a linear response, with focus changes based on how far you turn the control ring, not how quickly, are preferred for most video work. Turning the ring slowly nets minute, fine adjustments to focus, while a quicker action shifts the focus point dramatically.
SIGMA 35MM 1.4 MANUAL
Manual focus response is nonlinear, something I appreciate for photography, but that isn't great for video. It's something to worry about if you're using the lens for video, notably for shots where focus racks from one focal point to another, but not a practical concern for still photographers.
SIGMA 35MM 1.4 ISO
Sony a7R IV, f/1.4, 1/200-second, ISO 100Īutofocus is quick and quiet, but the lens does show a visible breathing effect, a change in its angle of view, when setting focus. The lens includes a toggle switch to swap between manual and autofocus modes, an aperture ring with support for third-stop clicks or silent operation, and a customizable function button. There are several control surfaces on the lens itself, beyond the standard manual focus ring. It's well engineered, with a push-button lock system to keep it in place, and is reversible for storage. The barrel is a mix of metal and polycarbonate.Ī lens hood is included, made from polycarbonate material. The front element has an anti-smudge protective coating, one that makes it easy to wipe away water droplets and stray fingerprints. Unlike the Rokinon, Sigma includes dust and splash protection here, so you can take the lens out in inclement weather without worry.
It's a better built lens than those from true budget brands, and you won't spend much more to get it versus one like the Rokinon 35mm F1.4 AF. It's a lighter lens to carry versus the Sigma 35mm F1.2 (5.4 by 3.5 inches, 2.4 pounds), and just a little bulkier than Sony's $1,400 FE 35mm F1.4 GM (3.8 by 3.0 inches, 1.2 pounds). It comes in at 4.4 by 3.0 inches (HD), weighs 1.4 pounds, and supports 67mm front filters. The lens is on the large size for a prime, but balances well on the full-frame Sony a7R IV camera that we used to test the lens. Best Malware Removal and Protection Software.
