Anamorphic Lenses: A Cinematic Gaze Now Accessible to Mirrorless Shooters

Anamorphic lenses, once exclusive to high-complete cinema production, are now a viable option for photographers and videographers using mirrorless cameras. These lenses offer a unique aesthetic – wider frames, enhanced background blur, and a distinctive visual character – that can dramatically alter the feel of footage. This shift is largely due to manufacturers like Sirui, who are blurring the lines between cinema and still photography with lenses like the 35mm T2.9 1.6x Anamorphic.

Understanding the Anamorphic Squeeze

The core characteristic of an anamorphic lens is its “squeeze factor.” The Sirui 35mm, and the entire Venus line, utilizes a 1.6x squeeze. This means the image is compressed horizontally during capture. In post-production, the footage is “de-squeezed” to reveal a wider aspect ratio. For example, a full-frame sensor with a standard 3:2 aspect ratio will yield a 2.4:1 aspect ratio after de-squeezing. Shooting 16:9 video results in a 2.8:1 aspect ratio. This process effectively widens the field of view horizontally, approximating the view of a 22mm spherical lens while maintaining a tighter vertical field.

Benefits Beyond Aspect Ratio

Anamorphic lenses offer several advantages:

• Unique Aspect Ratios: Capture cinematic aspect ratios without cropping, preserving more pixel data.
• Distinctive Bokeh: Anamorphic lenses produce oval-shaped highlights (bokeh) when de-squeezed, a signature cinematic look.
• Enhanced Depth of Field: At T2.9, the Sirui lens can achieve background blur comparable to a 20mm lens at f/1.8, providing greater subject separation.
• Cinematic Flares: Many anamorphic lenses create long, horizontal flares when light sources are present, adding a stylistic element.
• Creative Expression: They offer a different visual approach compared to traditional lenses, expanding creative possibilities.

Trade-offs to Consider

While offering a unique aesthetic, anamorphic lenses aren’t without their drawbacks:

• Sharpness: Spherical lenses generally exhibit greater sharpness across the frame.
• Light Transmission: Spherical lenses typically transmit more light.
• Autofocus: Many anamorphic lenses, though increasingly fewer, require manual focusing.
• Cost: Anamorphic lenses can be more expensive than comparable spherical lenses.
• Size and Complexity: They tend to be larger and more complex to manage, particularly on gimbals.

The Rise of Accessible Anamorphic Options

The market for anamorphic lenses is expanding. Newer models are becoming smaller and more affordable, and autofocus anamorphic lenses are now available. Christopher Frost’s recent reviews of Sirui’s full-frame autofocus anamorphic lenses highlight a major firmware update that has largely resolved initial issues with these lenses. Fstoppers details how these lenses create a more cinematic feel, and Photography Life provides an in-depth review of the Sirui 35mm T2.9.

Is Anamorphic Right for You?

If you prioritize a unique look and are willing to accept the trade-offs, an anamorphic lens can be a powerful tool. The choice hinges on whether you value a clean, natural image or one with built-in personality. The increasing accessibility of anamorphic lenses means that experimenting with this cinematic style is now within reach for a wider range of filmmakers and photographers.
