If you’re in the market for a mirrorless prime that combines impressive optical performance, outstanding build quality and remarkable portability, look no further than SIGMA’s full-frame I series range for L-Mount and Sony E-mount systems. And until 22 August we’re offering up to £70 cashback on all four of these stunning I series optics!

Despite having a robust all-metal build, including the lens hood, they’re remarkably small and light, weighing in at between 215g and 405g, so are ultra-portable. Used on the full-frame SIGMA fp L, it’s possible to achieve an exceptionally lightweight set-up that is ideal for landscapes, street photography, events and documentary work. Put a SIGMA full-frame fp L body in your kitbag with the 24mm and 45mm I series primes, for example, and the total set-up weighs in at just 867g – that’s about the same weight as an equivalent full-frame DLSR body without any lenses!

Sitting in the Contemporary line, I series primes are designed to combine portability with optical excellence, delivering impressive image quality across the whole aperture range. Each lens comes with a manual aperture ring so that you can change aperture on the lens body if you prefer, and the 24mm, 35mm and 65mm come with magnetic all-metal lens caps.

To take advantage of this fantastic I series cashback offer, all you need to do is purchase one or more of these lenses from new from a participating UK-based retailer* then fill in the cashback claim form. We’ll take care of the rest!
