Petzval adapter Vormaxlens Torsion
anamorphic adapter for lens

Torsion is an adapter Petzval mod that attaches to the taking lens (your lens). It is a real telephoto adapter -1.1x with twist image.

Petzval mod adapter attach in front of the taking lens. Focusing is done the taking lens, the adapter has a through single focus.

The adapter is able to focus on lenses from 20 mm to 150 mm and has a mount 67 mm in diameter. Attachment of the adapter is carried out directly to the taking lens or through a special clamping device (clamp) to align the adapter horizontally. The clamp is sold separately, made in a simple ring design with external and internal thread and the ability to fix in the desired position with adjustable or hidden bolts.

Anamorphic adapter can be installed on any lens with different diameters using adapter rings to 67 mm (mount of anamorphic adapter). It is desirable that the diameter of the front lens of the taking lens was less than 65mm. If it is more, may experience vignetting and spherical aberration.

Lenses with the best sharpness are 37mm 2.8, 40mm 2.8, 45mm 2.8, 50mm f2, 55mm f2. 58mm f2.8.

Anamorphic adapter works with zoom lenses. Values may vary for zoom lenses, vignetting may occur at a slightly longer focal length. If the front filter of your lens rotate - then the installation of the anamorphic adapter will have to be undertaken on the rig (cage) next to the lens. The anamorphic adapter must not rotate during shooting, otherwise the horizontal compression ratio will change.


Petzval mod adapter is enclosed in a metal case with glass optic.

Tele photo ratio is about 1.1x.

The diameter of the Petzval mod adapter is 72/77 mm. There is also 72/77 mm thread for filter (macro filters may be used to shoot very close objects).

This adapter can work with autofocus.

It is better to use the adapter for APS-C and MFT crop cameras.

If you purchase this adapter for a full frame, you should understand that we do not guarantee that it will work on this format.

The maximum sharpness of shooting is achieved at a distance of 10 – 20 meters, when the focus is 20 mm to 50 mm. At a distance closer than 3m, it is necessary to use diopters +0.3/+0.5. If necessary, close-range shooting, if there are no diopters – you can clamp the diaphragm of the taking lens. The sharpness at infinity is in acceptable quality.

Length - 40 mm, diameter - 77 mm, mounting - 67/72 mm. Weight ~ 120 grams.

Does not compress the image, only creates anamorphic-like effects.
