The Irix Dragonfly 45mm F/1.4 GFX is a normal prime designed for cameras with a 645D (0.8X) sensor. This ultra-bright prime has a 45mm focal-length. It provides the same field of view as a 36mm lens on a Full-Frame camera.
This prime lens focuses down to 40cm from the imaging plane. The lens is not capable of autofocus and so the focus-distance must always be manually adjusted via the focus-ring.
The lens weighs 1.12kg. Its body is weatherproof against adverse weather such as rain and snow. Seals in key areas prevent entry of water and dust.
This lens is only available for the Fujifilm G mount. It directly attaches and is fully compatible with all Fujifilm G mount cameras.
