Optical Properties
Are you looking for a new classic focal length lens? Defy all standards! The 45mm focal length will let you capture the world more creatively than a standard 35mm and 50mm focal length. At the same time, the fast aperture of f/1.4 will allow you to effectively separate the subject from the background. The Irix 45mm f/1.4 lens was designed to produce an extremely sharp image at only f/1.4. Thanks to the 9-rounded aperture blades, the areas outside the depth of field remain smooth; the bokeh is clean and beautiful.

At Irix, we believe that a lens is not just a tool in the hands of a photographer. The overall impression of the photo creation process is also important to us. The lens has to be fun and easy to use! That is why the ergonomics and design of our products are so important to us.
The Dragonfly version is a combination of reinforced metal and composite elements. This combination has resulted in an extremely durable, compact structure, which thanks to numerous seals, remains resistant to adverse weather conditions.
Focus Ring
We know how much you liked the focus ring on the Irix 150mm f/2.8 Macro 1:1 lens, so we decided to use a similar one on the 45mm f/1.4 lens. After many tests, we have developed a ring material characterized by its high mechanical strength and resistance to harsh conditions. Its special texturing allows for reliable and precise focusing, and dedicated embossed dimples allow you to feel the position of the ring, making focusing even easier.
Focus Lock
Focus Lock allows you to lock the focus ring in a specific position. This is especially useful when we want to maintain a specific distance to the subject (zone-focusing), or when we want to maintain perfect focus on infinity during landscape photography.
