Objetiva Irix 45mm f/1.4 Dragonfly para Canon EF - foco manual de distância focal fixa, resistente às intempéries, liga de magnésio

Where most fast primes stop at f/1.8, the Irix 45mm f/1.4 Dragonfly pushes into true low-light territory while keeping a compact, all-metal build. Designed for Canon EF full-frame cameras, this manual focus lens pairs a bright f/1.4 aperture with a 50.1° angle of view — ideal for environmental portraits, street scenes, and available-light shooting. The Dragonfly series is known for its rugged construction, and this 45mm is no exception: a magnesium-aluminum alloy barrel with three rubber seals protects against dust and moisture, so you can work in challenging conditions without hesitation.

Highlights

• Ultra-bright f/1.4 maximum aperture for shallow depth of field and low-light performance
• Full-frame coverage with Canon EF mount — compatible with APS-C as well
• Manual focus with a smooth, precise focus ring and focus lock feature
• Weather-sealed construction (3 rubber seals) for dust and moisture resistance
• Clickless/clicked aperture ring switchable for video or stills
• Neutrino coating reduces flare and ghosting for high contrast

In daily use

The 45mm focal length sits between the classic 35mm and 50mm, giving you a natural perspective that feels neither too wide nor too tight. With a minimum focus distance of 0.4 m, you can get close enough for detail shots while still capturing environmental context. The 9-blade rounded diaphragm produces smooth, creamy bokeh, and the hyperfocal scale helps with zone focusing for street photography. The large 86mm front filter thread accommodates standard filters without step-up rings. The focus lock prevents accidental shifts, and the aperture ring can be de-clicked for silent adjustments during video recording. Built to withstand the elements, the lens is a reliable companion for outdoor shoots in unpredictable weather.
