with Sigma 30mm F2.8 EX DN lens. Sigma makes
autofocus lenses for the
Sigma SA,
Canon EF and
RF,
Nikon F and
Z,
Fujifilm X,
Minolta/
Sony α and
E,
Pentax K,
Leica L,
Four Thirds, and
Micro Four Thirds lens mounts. Each lens may not be available in all mounts, and may lack certain features (such as HSM) on certain mounts. In August 2013, Sigma announced that starting the following month, it would offer a mount conversion service for its newest "Global Vision" lenses—those with either an "A" (Art), "C" (Contemporary), or "S" (Sport) as part of their model name. For a cost that varies with lens and market—from $80 to $250 in the U.S., not including shipping costs—owners can send their lenses to their local Sigma company, which in turn sends them to Japan for mount replacement, including calibration and optimization for the new camera system. Lenses designed for DSLRs can be converted to Canon EF, Nikon F, Pentax K, Sigma SA, or Sony A mounts; those designed for MILCs can be converted to Micro Four Thirds or Sony E-mount.
Designations •
ASP —
Aspherical lens elements •
APO —
Apochromatic lens element(s), originally for "Advanced Performance Optics", not necessarily apochromatic •
OS — In-lens "Optical Stabilization", analogous to Nikon VR or Canon IS •
HSM — "Hyper-Sonic Motor", either in-lens
ultrasonic motor or micro-motor, analogous to Nikon SWM (AF-S) (ultra-sonic or micro-motor), Canon USM (ultrasonic or micro-motor), Minolta/Konica Minolta/Sony SSM (ultrasonic motor) or Sony SAM (micro-motor), etc. •
A — "Art Series", large aperture prime and zoom lenses, high optical performance. USB dock compatible. Part of 2013 lens lineup restructuring. •
C — "Contemporary Series", combining optical performance with compactness. USB dock compatible. Part of 2013 lens lineup restructuring. •
S — "Sports Series", telephoto and super-telephoto lenses. USB dock compatible. Part of 2013 lens lineup restructuring. •
EX — "Excellence", EX-finish, high performance series. •
DG — "Digital Grade", coatings optimized for DSLRs, full-frame as well as APS-C, also usable on 35mm film SLRs •
DC — "Digital Compact", lenses for cameras featuring
APS-C size sensors, only •
DL — "Deluxe", indicates lower-end film era lenses •
DN — "Digital Neo", lenses for
mirrorless interchangeable-lens cameras (no longer used) •
DF — "Dual Focus", lens features clutch to disengage focus ring when in AF mode •
FLD — "'F' Low Dispersion" glass, the highest level low dispersion glass available with extremely high light transmission. This glass has a performance equal to fluorite glass which has a low refractive index and low dispersion compared to current optical glass •
HF — "Helical Focusing", front element of lens does not rotate (useful for polarizing filters and petal lens hoods) •
RF — "Rear Focusing", lenses employing rear-focusing, no length changes during focussing, no rotating front elements •
IF — "Inner Focusing", length of lens does not change during focusing, no rotating front elements •
UC — "Ultra-Compact"
