Anamorphic lens is an adapter that attaches to the taking lens (your lens). It is a real anamorphic adapter compressing the image.
Anamorphic 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 50 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 50mm. 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.
Budget versions of anamorphic adapters are more suitable for art shooting. They are less versatile because they are slightly longer. They have a little more distortion.
For camera crop factor of MFT (crop 2, micro 4/3) is better suited Compact anamorphic adapter. For Full frame cameras is better suited the Bigmetal adapters. Format APS-C (crop 1,5) is universal for anamorphic shooting.
Wideanamorphic 1.3x is enclosed in a metal case with combined optic - glass and polymer.
Compression ratio is about 1.3x.
The diameter of the anamorphic adapter is 82 mm. The diameter of the front lens is 80 mm. There is also 82 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 adapter is suitable for the Canon 35 mm, Canon 50 mm 1.8, 40 mm 2.8, Mir-1B 37 mm and similar lens on APS-C format. There is no vignetting on the crop sensor 1,6 and 1,5 with a focal length of 18 mm. On the crop sensor 2 (micro 4/3, 16 mm sensor) there is no vignetting at a focal length of 14 mm.
Given values are for fixed focal length lenses. Values may vary for zoom lenses. It is desirable that the diameter of the taking lens front element is less than 50 mm. It is also necessary to use very clear and sharp lenses as the anamorphic adapter greatly reduces the depth of field (it is harder to focus), slightly blurs the image around the edges.
The best performance adapter shows on lenses with a focal length of 14 mm to 50 mm on cameras with a crop factor of 1.5 or 2 (APS-C or MFT).
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 - 65 mm, diameter - 82 mm, mounting - 67 mm. Weight ~ 180 grams.
The adapter may have structural differences that do not affect the main characteristics.
The adapter does not have a clamping device included.
