Who decides it is impossible to combine portability with image quality?. However, SIGMA still believes that image quality is what matters the most. Even with a high ratio zoom lens, our goal is to satisfy enthusiastic photographers with the versatility of the lens and its optical performance.
The full frame lens features an aperture range from f/5-6.3 to f/22 and utilizes one FLD and three SLD elements. Also, this lens features a Hyper Sonic Motor for fast, quiet autofocus and has an Optical Stabilizer with an accelerometer for improved panning performance.
