Product description for Irix 150mm f/2.8 Macro f/1 Dragonfly Pentax K full frame

With a focal length of 150mm and a scale of 1: 1, these are the basic features of the new lens that allow comfortable work with small objects. Thanks to the possibility of moving away from the photographed object, the operation is more comfortable than with lenses with a shorter focal length. No shadows are cast on the subject, and lamps intended for this type of photography can be used.

Its fast aperture of 1: 2.8 allows for shorter exposure times, while the moderately long focal length of 150 mm is an excellent compromise between the narrow viewing angle desired for macro, commercial, and portrait photography and the convenience of handheld photography

.

The lens is equipped with an iris mechanism consisting of eleven iris blades with a rounded shape, which allow pleasant blurring of the background or points of light and ensure excellent sharpness even after stopping down the iris. The

focus ring has been equipped with a wide rubber grip with a special convexity press

.

For precise focusing of the balance with 270 degrees of rotation.

The

entire design is complemented by a functional Focus Lock ring that allows you to lock the focus ring in a suitable position.

The

Irix 150 mm 1: 2.8 Macro 1: 1 lens has been sealed in key points (the front element, the Focus Lock ring, the focus ring and the bayonet), making it suitable for use in adverse weather conditions such as fog and rain or snow

.

The optical design consists of twelve elements - three of them are made of ultra-low dispersion (ED) glass, four others are made of higher refractive index (HR) glass, and the entire glass is arranged in nine optical groups. Thanks to this design, we achieve near-zero distortion (at a value of 0.1%).

The Irix 150 mm 1: 1 lens is equipped with an internal focusing (IF) system, so the lens does not change its dimensions when focusing, maintaining a compact size and better sealing

.The

Irix 150 mm 1: 1 lens is the first model available in the new Dragonfly finish version, in which the aluminum frame is enclosed in an outer structure of aluminum-magnesium alloys and composite elements. The combination of Firefly and Blackstone features gives the lens lightness and robustness, while providing high mechanical strength and resistance in harsh weather conditions.

The

lens has a CPU that allows the iris to be controlled from the camera, and the AE module allows the use of semi-automatic modes (PASM)

.

This solution allows the user to receive confirmation of focus from the camera. An additional advantage is the recording of exposure data in EXIT format
