KODAK PHOTO PRINTER MINI FIRMWARE UPDATE MANUAL

There isn’t a lock to prevent the ring from being accidentally moved away from the ‘A’ point, but the distance between it and the nearest aperture setting is roughly double that of a full-stop adjustment, making it very distinct. When this is selected, the aperture is set and adjusted via the camera. As a photographer, the clicks are rather satisfying to feel, but they won’t please videographers and they can’t be avoided as there’s no ‘de-click’ control.Īlong with the aperture settings the ring has an ‘A’ setting. The aperture clicks are at very 1/3 stop, but the markings are at whole stop points from f/2 to f/22. It also feels well-made and unlikely to be moved accidentally. The aperture ring also has a nice action but its click stops make using your thumb and finger more comfortable. It’s easy to rotate without feeling too loose.

The focusing ring moves very smoothly and there’s no need to grasp it, it can be moved with pressure from one finger.

If my thumb and middle finger are on the aperture ring, I can reach forward comfortably to the focusing ring with my forefinger to adjust the manual focus. The aperture ring is sits roughly in the middle of the lens and it’s ideally located for rotating with the thumb and forefinger (or middle finger) of my left hand as I hold the camera from underneath.

I tested the 20mm F2 DG DN | C on the Sony A7R IV, and they make a great partnership and the lens seems perfectly sized and weighted for the camera. You have to reach down into the hood and get your fingernail under the edge of the cap to remove it. While the metal cap is a nice extra, I found it awkward to remove when the lens hood is in place.

Along with the usual plastic lens cap, Sigma supplies a metal, magnetic lens cap with the 20mm F2 DG DN | C. Yes, a metal lens hood, how often do you see that now?Īnd that’s not all that’s metal. I particularly like the deep knurling on the focusing and aperture rings, which is matched by the grooves on the petal-shaped metal lens hood. The lens has a delightfully high-quality appearance and it feels precision-engineered. The idea of an all-metal lens barrel is always attractive and it’s superbly delivered with the Sigma 20mm F2 DG DN | C. This can be used to customise some lenses and make firmware upgrades. Photographers with a Sigma, Leica or Panasonic camera with the L mount will find that the 20mm F2 DG DN | C is compatible with Sigma’s optional USB Dock UD-11. A scale could be useful for anyone shooting landscapes and wishing to use hyperfocal distance focusing. On a more disappointing note, Sigma hasn’t given the lens a focus distance scale. That latter point is helpful for anyone thinking of using the 62mm filter thread to mount a graduated or polarising filter. Ghosting and flare are suppressed by Sigma’s Super Multi-Layer Coating and Nano Porous Coating.įocusing is handled by a stepping motor that works internally, which means the lens stays the same length during focusing and the front element is static. Consequently, the lens should be a good choice for night sky photography.

Sigma has also designed the 20mm F2 DG DN | C to suppresses sagittal coma flare, which makes highlights likes stars look triangular. F Low Dispersion elements are also less brittle and easier to make than fluorite elements. The ‘F’ in F Low Dispersion denotes that the element is designed to have very high light transmission and offer similar optical performance to a fluorite element – but at lower cost. There’s also 1 SLD (Special Low Dispersion) element that reduces optical aberrations and 1 FLD (F Low Dispersion) element. Amongst those elements there are 3 aspherical elements that are designed to maintain sharpness into the corners of the image without the lens being large. Sigma constructs the 20mm F2 DG DN | C from 13 elements arranged in 11 groups. It’s large maximum aperture also adds to its appeal for astrophotography, interior and event photography. On an APS-C format camera, the 20mm focal length effectively becomes 30mm.Īs it has a focal length of 20mm, Sigma 20mm F2 DG DN | C is classed as an ultra-wide-angle lens, which makes it attractive for shooting landscapes and seascape. Both of those mounts feature on full-frame and APS-C format cameras. It’s specifically designed for use on mirrorless cameras and is available with either the L-mount or Sony E mount. Although it is compact, the Sigma 20mm F2 DG DN | Contemporary is a full-frame lens.
