Unique to the SIGMA I series is its Magnetic Metal lens cap. To ensure the cap performs to the same high standards as our lenses, technicians in our Aizu factory conducted unique field tests, checking for strength and durability.
SIGMA I series lenses are designed exclusively for full-frame mirrorless cameras. They feature high-quality optics and are constructed using precision-aluminium parts and an all-metal barrel, whilst remaining compact and lightweight. They also feature aperture rings for tactile aperture control and plus a dust and splash-proof mount. Idea for users who require high-quality everyday lenses.
