It doesn’t matter if you are a professional photographer looking for a lens for your next job, or an amateur looking to expand your lens set. The Irix 45mm is a fast f/1.4 lens with a classic 50 degree field of view, created for your full frame (35mm) camera. The combination of fast aperture and a classic focal length makes this lens extremely practical. You can use it both for portrait photos (on which you can blur the background effectively), or during a trip where you can take breathtaking landscapes creating extremely sharp images.
