Photographers and videographers have been raving about the world’s first constant aperture F1.8 zoom lens, the Sigma 18-35mm F1.8 DC HSM | Art lens since it was originally announced earlier this year, for both its groundbreaking maximum aperture, and its incredible prime-like performance, even wide open at an amazing price. It rocked the charts on DXOMark, besting top-shelf primes at comparable focal lengths, been recognized with a POP Award from PopPhoto.com, and a Gold award from DPReview, among other accolades.
Exploring the world through the Sigma 18-35mm F1.8 DC HSM | Art lens on the hunt for varying colors and textures, and levels sharpness and blur can create images that are at once new, and yet instantly recognizable. Close-up focusing on a pumpkin, for example, gives a shallow slice of sharpness, and lovely focus fall-off in a composition that’s pure seasonal color. And a single turning leaf backlit by the sun tells the story of autumn in a very different way than a sweeping vista of an entire hillside.
Just four short weeks ago Fedex showed up at my door with a shiny new Sigma 18-35mm f1.8 Art lens. […]
We’ve just announced the world’s first F1.8 constant aperture zoom lens, the Sigma 18-35mm F1.8 DC HSM | Art lens, and I’ll readily admit, we on the Sigma Corporation of America team have been just as excited about this lens leading up to launch as photographers have been since it was officially announced in the wee hours of April 18th. And now that I’ve spent some time with my hands on a preproduction version of the lens paired with my Sigma SD1, I, truly cannot wait ’til this lens starts shipping and I can share high-resolution end result photos! Today we’re going to focus on what we can talk about–the hand feel, build quality, and such of this brand new lens designed specifically for APS-C DSLRs.
2014 was a very busy year for Sigma. We announced a host of new lenses and cameras, offered the Sigma dp2 Quattro Test Shoot, and participated in trade shows, and dealer events across the country. Photographers all around the world have been talking about our new lenses in the Art, Sports, and Contemporary lines, as well as the completely redesigned dp series cameras.
Of the three main variables relating to creative and artistic control on DSLR and compact interchangeable cameras–aperture, shutter speed and ISO– aperture control, is for many beginners, the most difficult to grasp. Have no fear, we’re here to help. Learning how and when to select a wide or narrow aperture unleashes the creative and expressive potential of your camera’s lenses.
A zoom lens is a type of camera lens that is offers the photographer a useful range of different focal lengths in a single lens. This is in comparison to a prime lens, which only offers a single focal length. A zoom lens allows for quick and easy re-framing of a scene while staying in the same physical position. Sigma offers a line of over 20 zoom lenses for DSLR photographers, ranging from wide angle zoom lenses, supertelephoto zoom lenses, and high-zoom ratio all-in-one lenses for both full-frame (DG) and APS-C (DC) digital cameras.
Our technical product information has been expanded to now include both Geometric and Diffraction MTF charts for new Sigma lenses.
