If you keep up with the DSLR lens scene, you'll know about the bizarre 18-35mm lens Sigma announced two months ago. While most zoom lenses lose light as you zoom in, higher end models maintain the same maximum aperture throughout the entire zoom range from 18-35mm. This has all been done before, but the Sigma manages to stay at a mindblowing f/1.8 (anything below f/2 is considered to be pretty impressive). And today, Sigma priced this gem at a low $799. Read on for all the details!
Specs and Availability
Designed for APS-C size sensor DSLRs, the lens officially known as the Sigma 18-35mm f/1.8 DC HSM Art lens. Since it's made for crop sensor cameras, the focal length is the equivalent of 17-52.5mm on a 35mm full frame camera. The constant maximum aperture of f/1.8 throughout the zoom range sets a precedent for zoom lenses to come. The lens is constructed of Thermally Stable Composite material, has an improved AF/MF switch, and features a Super Multi-Layer Coating to reduce flare and ghosting. Top it all off with a HSM motor for silent operation, and this is the killer lens for artsy shots. Oh and nine aperture blades - just imagine the bokeh you'll get with this lens! This piece of glass with be available for a cheap $799 come this July, for Sigma and Canon mounts. Nikon, Sony, and Pentax compatible models will be made available later on.
