Two new sd Quattro cameras
The essence of photographic expression:
fine lenses for a truly powerful system camera.
The SIGMA GLOBAL VISION series of high-performances lenses comprises three distinct lines and concepts: Contemporary, Art, and Sports. SIGMA has developed each of the lenses in these three lines using the Foveon X3 direct image sensor to ensure their world-class optical performance. Offering the outstanding expression that photographers demand, the SIGMA sd Quattro series is a complete and powerful system compatible with these fine lenses.AF Operation on sd Quattro series
The culmination of the SIGMA philosophy:
“The lens is the key to the photograph”
Top-performing lenses developed using the highest-resolution image sensor
Since their introduction in 2012, the SIGMA GLOBAL VISION series of lenses has received an enthusiastic welcome from photographers around the world. In order to create these fine lenses, SIGMA revolutionized its production system and aimed to endow them with ultimate quality in every respect:
1. Design: All lens designs are based on a stringent and comprehensive development concept.
2. Manufacturing: All lenses are made in Japan using the most advanced production technologies.
3. Assessment: Performance standards for each lens are carefully developed and stringently applied. For example, all lenses are tested with the A1* proprietary Modulation Transfer Function (MTF) measuring system using 46-megapixel Foveon direct image sensors.
*A1 = AIZU 1
A system that treats lenses as true assets:
Optional SIGMA USB DOCK for customizing focus position and more
Available Mount Conversion Service for growing and maintaining lens assets
SIGMA supports the SIGMA GLOBAL VISION lineup with comprehensive products and services that help photographers get more value out of their fine lenses and enjoy using them over the long term.
The SIGMA USB DOCK is a dedicated accessory for lenses in the Contemporary, Art, and Sports lines. Simply placing a lens in the DOCK and connecting it to a personal computer via a USB cable, photographers can use the exclusive SIGMA Optimization Pro software to update lens firmware and customize the focus position and other settings. Photographers can also select the autofocus speed and adjust the focus limiter and Optical Stabilizer (OS) function on lenses that have a custom mode switch.
The Mount Conversion Service is available for all SIGMAL GLOBAL VISION lenses. For a fee, SIGMA will convert a lens mount to a mount for a different camera body. This service helps photographers use valuable lens assets for many years to come, unrestricted by their original choice of camera system.
