• What is an anamorphic lens?

Commonly used in filmmaking to achieve a cinematic look, an anamorphic lens is a specialized lens that horizontally compresses the image during capture and then expands it during playback or post-processing. Anamorphic camera lenses allow for a wider field of view, creating a distinct widescreen aspect ratio and unique optical characteristics such as lens flares and stretched bokeh.

• How do anamorphic lenses work? 

Anamorphic lenses utilize a cylindrical optical element to horizontally squeeze the image onto the camera's sensor or film frame. This compression alters the aspect ratio, resulting in a narrower, vertically stretched image. During playback or post-processing, the footage is de-squeezed to restore the original widescreen format. This process widens the field of view, providing a distinct cinematic aesthetic with enhanced horizontal resolution and unique optical characteristics such as lens flares and oval-shaped bokeh.

• What is the aspect ratio of anamorphic lenses?

The aspect ratio of anamorphic lenses typically depends on the specific format being used. In the realm of professional filmmaking, the most common anamorphic aspect ratios are 2.39:1 and 2.35:1. These ratios result from the horizontal compression and subsequent de-squeezing of the image during playback or post-processing. The wide aspect ratio achieved with anamorphic lenses allows filmmakers to create expansive, immersive visuals that are synonymous with the cinematic experience.

• Are there different types of anamorphic lenses?

Yes, there are different types of anamorphic lens. The most common anamorphic lenses are 1.33x, 1.6x, and 2x, and these refer to how much the lens squeezes the horizontal image onto the sensor. For instance, a lens with a 1.6x squeeze ratio will capture 1.6 x the width of the focal length. Our range includes both 1.33x and 1.6x anamorphic lenses as well as a 1.25X adapter allowing for up to 2x on the 1.6x lens range.

• What is the S35 frame?

The S35 frame, also known as Super 35mm, is a common image sensor size used in film cameras. Its dimensions are approximately 24.89 x 18.66mm. This format is primarily used in film and video production.

• What is the difference between S35 and Full Frame?

Full Frame sensors have dimensions of about 36 x 24mm, which is larger than S35 sensors. This means that Full Frame sensors can provide a larger field of view and better low-light performance. Additionally, Full Frame lenses typically require larger, more complex lens elements and optical designs, which can make them more expensive.

• What is the difference between S35 and APS-C?

APS-C sensors usually have dimensions ranging from 22.2 x 14.8mm (Canon) to 23.6 x 15.6mm (Nikon, Sony, etc.), which are smaller than S35 sensors. This means that S35 sensors can provide a larger field of view. Moreover, APS-C is the standard for most consumer and professional digital SLR (DSLR) and mirrorless cameras, while S35 is the standard in film and video production.

• Which frame should I choose?

This primarily depends on your shooting needs and budget. Full Frame provides the best image quality and the largest field of view, but it may be more expensive. S35 and APS-C might be more suitable for photographers with a limited budget but still want to achieve high-quality images.
