![]() Real-World Tests of the Sigma 30mm f/1.4 DC DN Contemporary Lens Nine rounded aperture diaphragm blades should help give pleasant-looking out-of-focus areas. The lens has nine elements in seven groups, two of which are aspherical. It takes a 52mm filter that can be used with the hood. The lens is supplied with a robust lens hood and lens caps. The focusing ring is made from textured rubber. The body is made of what Sigma describes as a Thermally Stable Composite, which it claims exhibits minimal deformation over time. The Leica L Mount and Fujifilm X Mount versions are sealed to improve weather tightness, but not with the Micro Four Thirds version I use or the Sony E mount and EOS-M mount versions. On unboxing it, I found a sleek-looking, solid, but lightweight lens. ![]() ![]() The lenses arrived in recyclable packaging, and the box Sigma had packed them in for postage was reused. I use only OM System PRO lenses, so I am used to sharper than a scorpion sting results, so I was intrigued to know how this lens would perform. From the Lumix camp, there's the Summilux 25mm f/1.4 ASPH. However, with Micro Four Thirds, it will compete with the Olympus 30mm Macro lens, which is slower at f/3.5, the 25mm f/1.8, and the faster 25mm f/1.2 Pro lens. There are neither OM System (Olympus) nor Panasonic lenses that match the specifications of this. So, this should be a good portrait and street photography lens. Mounted on a full frame, on a Sony E mount, the field of view is 50.7°. But, thinking about it, it gives a 39.6° field of view on Micro Four Thirds cameras, thus similar to the ubiquitous "Nifty Fifty" lenses on a full frame camera. I'll be reviewing that shortly.Īt first, the 30mm for Micro Four Thirds cameras struck me as a strange focal length. There was this one and the wider 16mm f/1.4 DC DN that I had also agreed to put through the mill. Two lenses arrived in the post from Sigma for me to test. I tested the Micro Four Thirds version on my OM-1. It is not currently available for Nikon users. The lens is available for Sony E, Canon EF-M, Leica L, Fujifilm X, and Micro Four Thirds mounts. I didn't even look at the B&H website to see what the lens retails at retail price is a good indicator of image quality. Furthermore, I don't own any Sigma lenses, so I made no presumptions. I never read other reviews before testing lenses, which was true of this lens.
