![]() ![]() This is tempered by the distance sale that is visible in the viewfinder in manual focus mode and the availability of a range of depth of field smartphone apps, but it is still something many photographers mourn in the transition to fly-by-wire focusing.Īt £749, the 35mm F1.4 DG DN Art is almost half the price of the Sigma 35mm f/1.2 DG DN Art. On the downside, the new lens lacks the original’s focus and depth of field scale, which can be useful, especially for landscape photography. It also gains an aperture ring, which is great addition, speeding aperture adjustment and enabling you to take control before the camera is even powered up. ![]() Sigma 35mm F1.4 DG DN Art Sample Photo, 1/60s, f/6.3, ISO100, Sony A7R IV And of course, it also delivers superb image quality, especially if you close down to f/2 or smaller. It’s smaller and lighter, yet its build quality is excellent, making it a pleasure to use. The original 35mm F1.4 DG HSM Art is a great lens that has proved very popular with many photographers and, although I haven’t been able to compare the two directly, the 35mm F1.4 DG DN Art seems a worthy update. The out of focus areas look nice and smooth with small highlights looking good, with no aberrations and often maintaining their round shape into the corners of the frame. Fortunately, these can be dealt with in a matter of seconds using Adobe’s Defringe tools.Īlthough it’s a wide lens, the large aperture settings available enable subjects to be separated from the background by selective focusing. Sigma 35mm F1.4 DG DN Art, Sun-star, 1/40s, f/14, ISO160, Sony A7R IVįlare is very well controlled, but I was able to find a few examples of chromatic aberration along strongly backlit edges in a some of my images. ![]() There’s also a little fall off in sharpness towards the corners at f/1.4, and again it’s improved by closing to f/2, or even better, f/5.6. The difference is obvious if you look at images at 100% on a computer screen, and though subtler, it’s still apparent if they are sized to fill a 27-inch screen. While the 35mm F1.4 DG DN Art is sharp wide-open, it’s appreciably better when the aperture is closed to f/2. As focus is adjusted from infinity to the closest point, the field of view changes slightly and it looks like the lens is zooming in a little. Focus breathing, however, could be an issue for videographers or photographers wishing to focus stack a series of images. In practice, this is unlikely to be picked up by a camera-mounted microphone except in a silent studio environment. While the focusing mechanism is generally silent, it occasionally makes a a slight sound, mainly at the closer focusing distances. Sigma 35mm F1.4 DG DN Art Close Focus, 1/1000s, f/2, ISO125, Sony A7R IV ![]() It’s also compatible with Sony’s Eye AF and when it’s mounted on the A7R IV, the camera is quick to spot human or animal eyes, depending upon the setting. There are faster optics, but it’s responsive enough for the situations in which it’s likely to be used most often. The combination of a single lightweight focusing element and a stepping motor enables the lens to focus quickly and silently on many occasions. The lower switch enables the lens aperture ring to be declicked, so that it rotates smoothly and silently without the usual haptic and audible feedback. Recent Sony mirrorless cameras enable one of a long list of features to be assigned to this button, and I opted for ‘Focus Magnifier’ to let me check the focus quickly whether the lens is set to AF or MF. Below this is a customisable button marked AFL. The uppermost of these is the AF/MF switch. There are two switches and button on the left of the lens barrel. ![]()
