A beautiful little film from Diego Contreras filmed in NYC with the GH4 and the SLR Magic Anamorphic 1.33x lens.

In the past, many indie filmmakers who wanted to shoot anamorphic had to depend on rare vintage lenses, which was not always reliable. To achieve the much loved 2.35:1 scope aspect ratio, which gives a very pleasant, epic effect, filmmakers must crop off the top and bottom of standard 16:9 footage when using spherical lenses with modern digital cameras. As a result, 25% of sensor/negative information is discarded.

As a commitment to the film industry, SLR Magic developed this 1.33x anamorphic adapter to help filmmakers maximize their image quality by preventing this loss of vertical resolution. The unique 1.33x squeeze factor uses the entire 16:9 sensor/negative area to achieve the desired 2.35:1 aspect ratio. The Anamorphot 1.33x does this by compressing a 33% wider field of view to fit the width of the 16:9 sensor/negative without compressing image height.

Modern professional cinema cameras have large sensors capable of capturing an image in the 2.35:1 format directly, using spherical lenses, but film makers still desire the anamorphic “look” which often limits them to using rare vintage lenses. These present a number of difficulties in practice such as size, weight, lack of close focus, availability, and high price. We sought to overcome such issues with the SLR Magic Anamorphot.


The SLR Magic Anamorphot 1.33x creates unique effects such as horizontal lens flare, commonly referred to as anamorphic streaks, and may create slightly elongated bokeh when achromatic diopters are used.  Over the history of cinema, these same stylish effects have contributed to the cinematic look of epic motion picture photography.  Characteristics that shape this anamorphic look come from Front-mounted anamorphic adapter designs such as the SLR Magic Anamorphot while Rear-mounted anamorphic designs have more suppressed anamorphic characteristics.


PLEASE NOTE: The SLR Magic Anamorphot 1.33x Attachement lens may have slight cosmetic imperfections such as small dust motes which has no observable impact on image quality. (PLEASE SEE THE LAST PHOTO ABOVE FOR AN EXAMPLE). It usually takes a lot of imperfections to perceptibly degrade the image quality of a lens. If this is an issue, please do not purchase the Anamorphot kit as returns will not be accepted due to these slight cosmetic imperfections and any dust particles that settle within the optics. This is normal and to be expected and is much better than used anamorphic attachments available elsewhere.

Technical Specifications:

Lens Type: Anamorphic adapter
Front filter thread: Φ77

Rear filter thread: Φ62, Φ58, Φ52, Φ49  

Lens Coating: Multi Coated

Close Focus: dependant on taking lens compatibility

Weight (oz./g): 13.4/380
Optional accessories: SLR Magic 77mm Achromatic Diopter Set (+0.33, +1.3)

Suggested taking lens based on sensor size:

17-85mm focal length can be used for S16 sensor.

20-85mm focal length can be used for mFT (M4/3) sensor.

35-85mm focal length can be used for S35 and APS-C sensor.

40-85mm focal length can be used for Full Frame sensor.


Taking lens compatibility:

Lenses with non-rotating front filter threads must be used. The front element of the taking lens should be as close to the rear element of the SLR Magic Anamorphot 1,33x possible without making contact. It isn't necessary for the taking lens to have an internal focusing mechanism. Trial and error will be involved but, in general, the SLR Magic Anamorphot is best paired with a prime lens whose front element (not to be confused with its filter thread) is smaller than 50mm in diameter.

Q: How do you treat the image in post? Adobe Premiere and Photoshop?

A: Video - There are a few ways to do it in Premiere but we like to create a sequence based on the clips native setting whether its 4k or 1080 or 720. We put 1 clip on the timeline and change the motion settings in the Effects Control tab. Uncheck Uniform Scale and then change the height from 100 down to 50 if using a 2x lens. Or from 100 down to 75 if using a 1.5x. Some people will change the width from 100 up by 2 or 1.5x depending on the squeeze strength of the lens. Sometimes you'll bump it up or down a little to your liking. We personally leave it squeezed a little so that it screams cinemascope even more.

From there, just copy the clip and paste attributes to all the other clips in the timeline.

A: Photo - To de-squeeze, in Photoshop if your image is 1920 pixels in width and 1080 pixels in height you would adjust the height down by 50% or divided by 2 to 540 if using a 2x lens. Or double the width from 1920 to 3840 leaving the height at 1080.

You'll need to uncheck Image Constraints. Otherwise when you adjust the height the width will also try to stay constrained.
