on the same SMD module and should be avoided too.

Use of SLR Magic Achromatic Diopters (Optional)

These highly corrected glass elements will minimize chromatic aberration and distortion while
allowing a stop faster maximum aperture with increased sharpness. The SLR Magic +0.33
achromatic diopter is good for 1.5 - 3 meter focus distance while the +1.3 achromatic diopter is
good for focus distance under 1 meter. Achromatic diopters may be stacked but this is not
recommended for taking lenses with a focal length of less than 35mm to avoid vignetting.

How to process footage

The SLR Magic Anamorphot 1,33x – 50 increases horizontal field of view by 33%, squeezing it
to fit a 16:9 HDTV frame. Several methods exist for un-squeezing and working with
anamorphic footage in your editor or effects software. You could specify a project resolution of
2554 x 1080 and scale your footage to match the project's width (footage must be shot in 16:9
ratio). Or, if you're primarily interested in uploading to the web you could instead specify a
project resolution of 1920 x 812 and scale your footage to match the project's height (footage
must be shot in 16:9 ratio).
In a standard 16:9 project, a vertical scale of 25% applied to anamorphic footage will unsqueeze
to the correct aspect ratio, creating a "letterboxed" image with black bars top and
bottom, while advanced users might specify a project with a pixel aspect ratio of 1.33:1 and
applying this interpretation to the anamorphic footage. Working in this fashion instructs the
editor that it should un-squeeze for display purposes without actually modifying the footage.
The SLR Magic Anamorphot 1,33x – 50 is compatible with variable aspect ratio still and video
cameras (i.e. 3:2, 4:3, 1:1). Simply scale your anamorphic image horizontally by 33%,
preserving the image's original height or scale vertically by 25%, preserving the image's
original width.
