IRIX - Macro Lens 150mm f / 2.8 Dragonfly:
THE GATEWAY TO THE MACRO WORLD
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 field of experience - the Irix 150mm f / 2.8 Macro 1: 1 lens is a created macro lens. for your full frame (35mm) camera and is available in Nikon F, Canon EF and Pentax K mounts.
The lens allows you to take macro photos with a magnification ratio of 1: 1. When using a camera with an APS-C sensor, due to the cropping factor, the magnification ratio increases to 1.5: 1.
READY FOR ALL CONDITIONS
It doesn't matter if you're crossing the hot sands of the Sahara or the frigid expanse of Antarctica - Irix lenses don't shy away from any challenge.
The sealing system has been designed to protect the inside of the lens from moisture, dust and sand. Equally important, the lens does not change its dimensions when focusing, thus eliminating the risk of dirt particles being carried away into the internal structure.
The whole body remains strong and studied, and ready to function under any conditions.
OPTICS THAT GUARANTEE SHARP IMAGES
The creativity, ideas and effort put into a photograph would be nothing without the right lens. Thanks to many years of experience in optical design, the Irix 150mm f / 2.8 Macro 1: 1 lens has been meticulously crafted for incredible clarity. The optical design was thought to produce an extremely sharp image starting at f /2.8. The use of 11 blades with rounded aperture not only results in an extremely smooth and soft bokeh, but also in the minimization of the diffraction phenomenon (decrease in resolution associated with stopping the aperture). With an additional stop, the sharpness of the image improves further, which is crucial in macro photography, as we often have to use small aperture values ??to achieve a sufficiently large depth of field.
You compose the frame - we take care of the rest!
READY FOR ALL CONDITIONS
[Dragonfly finish]
It doesn't matter if you're crossing the hot sands of the Sahara or the frigid expanse of Antarctica - Irix lenses don't shy away from any challenge.
Reinforced metal construction
Scratch resistant finish
Non-slip focus ring with special finish for easy focusing
Engraved markings filled with UV reactive paint
Seals to protect against dust and water (tropicalized construction)
Hard carrying case included
The Dragonfly finish is a combination of reinforced metal and composite elements. This combination has resulted in an extremely durable construction which, thanks to numerous seals, remains weather resistant.
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 important to us. Goals should be fun to use! This is why the ergonomics and design of our products are so important to us.
OBJECTIVE TO INTELLIGENT DESIGN
The Irix 150mm f / 2.8 Macro 1: 1 has a module that lets you control the lens iris directly from the camera, thanks to the popular semi-automatic modes (PASM) and l 'data recording in EXIF ??format.
The use of electronics also allows the lens to be equipped with a focus confirmation system - the camera announces the correct focus setting (as an icon in viewfinder or with sound), whenever you set the focus correctly - it's simple and convenient!
ADDITIONAL FEATURES
Focus Lock - allows you to lock the focus ring in a specific position. This is extremely beneficial when you want to be sure that you are setting the correct magnification ratio eg. 1: 1 while shooting.
Tripod clamp (Arca Swiss standard) - macro photography requires extraordinary precision. We have good news for all photographers using a tripod: with the tripod collar, you can securely attach your camera to the lens. With this solution, the center of gravity of the camera lens remains neutral and vibrations associated with focusing and operating the camera are minimized.
Focus Ring - when shooting small items, the depth of field usually only covers a few millimeters or less, so it is important that the sharpness is precise. The rotation angle of the focus ring on the Irix 150mm f / 2.8 Macro 1: 1 is up to 270 degrees, ensuring extremely smooth and precise sharpness.
Ergonomics of the focus ring - After extensive testing, we have developed a ring material characterized by its high mechanical strength and resistance to adverse conditions. A special texture allows for reliable and precise focusing, and dedicated raised positions allow you to feel the position of the ring even without searching for it, making focusing even easier.
