The production time is 1 week.
The adapter is suitable for shooting widescreen video.
Made in a metal case with combined optics - glass and polymer. The compression ratio is in the range of 1.45x.
Lenses have multi-illumination, anti-glare or other coating.
The diameter of the anamorphic adapter is 72 mm. The diameter of the front lens is 70 mm. Front thread for light filter 77 mm or 72 mm. You can set any filters 72/77 mm, for shooting very close objects, you can use macro filters. When shooting close-up with macro (closeup) filters, an oval bokeh is achieved in the background. The adapter can work on lenses with a focal length from 20 mm to 80 mm. The adapter has a 67mm mount for the main lens filter. It can be installed directly or through a special clamping device for leveling the horizon – Clamp. The clamp is sold separately.it is made in a simple ring design with external and internal threads and can be fixed in the desired position using adjustable or countersunk bolts.
The adapter is best used for APS-C and MFT crop cameras. The adapter shows the best performance on lenses with a focal length from 25 mm to 65 mm on cameras with a crop factor of 1.5 or 2 (APS-C and MFT). The adapter is suitable for Canon 40mm 2.8, Canon 50mm 1.8, Helios 44-2 lenses in APS-C format. Vignetting is absent on a full frame with a focal length of 58 mm (Helios) and on a crop sensor of 1.6 and 1.5 with a focal length of 40 mm. The crop 2 sensor (micro 4/3, 16 mm sensor) lacks vignetting at a 30 mm focal length. The values shown are for fixed focal length lenses, but the values may vary for zoom lenses. It is desirable that the diameter of the front lens of the main lens is less than 60 mm. It is necessary to use very clear and sharp lenses - anamorphic adapter greatly reduces the depth of field (harder to focus), slightly blurs the image, mainly at the edges of the image. Spherical aberrations are more pronounced in the full frame. The anamorphic attachment has chromatic aberrations that can be enormously removed or used for artistic photography.
Focusing is carried out by the main lens, the nozzle has a through focus. Maximum sharpness is achieved at a distance of 10-20 meters. Depending on the optical design of the main lens, diopters may be required at a distance closer than 3 meters +0.3/+0.5. if you need close – up shooting, if there are no diopters, you can tighten the aperture of the main lens. Sharpness at infinity is in acceptable quality.
The adapter may have design differences that do not affect the main characteristics.
Length - 97 mm, weight - 155 g.
The adapter does not have a clamping ring included.
