Perfectly weighted for mirrorless systems the new 65mm F2 DG DN | C blends a very compact design with an unusual but versatile focal length that is much loved by both photographers and film makers. This ultra sharp full frame optic is a perfect mid point between standard primes and classic portrait lenses, and is ideal for portraits, weddings, short telephoto landscapes, street photography and astrophotography. Anti ghosting and anti flare technology ensures high end performance in backlit conditions. The lens displays a particularly attractive bokeh effect thanks to the control of spherical aberration and its nine rounded diaphragm blades, with near circular out-of-focus highlights across the frame and at the widest aperture of F2. The 65mm F2 DG DN | C comes with a carefully machined metal lens hood, a feature not even found on Sigma’s Art series lenses. A large number of grooves called knurling are cut in, improving the lens operation by serving as slip resistance and giving the lens a premium look and feel unique to the I Series. A specially chosen plastic was used for the part that connects to the lens to ensure smooth operation. Included in the box is the regular Sigma plastic lens cap as well as an all-metal magnetic cap, which snaps firmly on to the end of the lens. With no requirement for a spring-loaded clasp, the cap has a sleek, minimal finish.
