Description
The Sirui Astra 75mm T1.8 FF AF 1.33X Anamorphic lens is a full-frame anamorphic lens with autofocus and 1.33x compression, designed for cinematic vision with a more compressed perspective and pronounced separation of the subject from the background. Compatible with Leica L mount, the model offers a T1.8 aperture, Full Frame coverage (44 mm image circle) and electronic communication with the camera. It has a 13-blade diaphragm, a minimum focusing distance of 0.6 m and a standard 67 mm filter thread, making it practical for a variety of shooting situations.
One of the most significant advantages of this model is the presence of autofocus and full body communication, which is rare in anamorphic lenses. This makes the Sirui Astra 75mm significantly more accessible and convenient to use, especially in dynamic scenes, handheld shooting or using a gimbal. Thanks to full electronic communication with the camera, the lens supports standard autofocus modes such as continuous autofocus, face and eye detection, and real-time subject tracking. This provides more precise and reliable focusing and expands the application of anamorphic vision to more flexible and dynamic shooting situations.
The 75mm focal length creates a more compressed perspective than wider anamorphic lenses, making it an excellent choice for portraits, details and cinematic close-ups. The 1.33x anamorphic factor expands the horizontal field of view (up to 36.9°), giving the characteristic widescreen look without excessive distortion. The neutral flare effect preserves the natural behavior of light, without strong coloration.
The T1.8 aperture allows for working in lower light and provides control over depth of field, creating a smooth and cinematic bokeh effect. The optical construction of 18 elements in 13 groups contributes to good sharpness and control over optical aberrations.
The minimum focusing distance of 0.6 m allows for close-up shots with a clearly defined background, and the 136° focal length provides sufficient precision when working with both autofocus and manual focus.
One of the key features of this model is the presence of autofocus – a feature rarely found in anamorphic lenses, where focusing is usually done entirely manually. Thanks to electronic communication, the lens supports standard autofocus modes such as continuous autofocus, face and eye detection, and subject tracking (depending on the camera), making it significantly more flexible in dynamic scenes.
The compact body with dimensions of 80 x 80 x 133 mm and a weight of 666 g allows for convenient handheld or gimbal operation, suitable for shooting in all situations and everyday use.
