This is a more perfect version. Chromatic aberration was removed. The second revision of 1.45x of Bigmetal. Shorter and sharper.
The lenses have a multi-lightening, anti-reflective or other coating. The diameter of the anamorphic adapter is 84 mm. The diameter of the front lens is 80 mm. The front thread for the light filter is 82 mm. You can install any filters 82 mm, for shooting very close objects you can use macro filters. Contraction coefficient of about 1.45x.
The adapter is able to focus on lenses from 20 mm to 85 mm and has a mount diameter of 67 mm. Attachment of the adapter to the taking lens is carried out directly 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 is attached from the front of the taking lens. The best sharpness is achieved on cameras with a crop factor of 1.5 or 2 (APS-C and MFT format).
Focusing is carried out by the taking lens, the adapter has a through focus.
The adapter may have structural differences that do not affect the main characteristics.
The adapter can work with full-frame cameras, but in this case, chromatic aberrations increase. This effect can be used in artistic shooting. Or chromatic aberrations can be programmatically removed.
When shooting close objects, the adapter can create an oval bokeh on the background.
The adapter is better to use for APS-C and MFT crop cameras. The best performance adapter shows on lenses with a focal length of 25mm to 65mm on cameras with a crop factor 1.5 or 2 (APS-C or MFT).
The adapter is suitable for the Canon 35mm, Canon 50 mm 1.8, 40mm 2.8, Mir-1B 37mm and similar lens on APS-C format. Is no vignetting on a full frame with a focal length 50mm (Helios) and on the APS-C sensor with focal length 35mm. On the sensor crop 2 (micro 4/3, 16 mm sensor) there is no vignetting at a focal length of 28mm. The values given are for fixed focal length lenses. For zoom lenses, values may vary. It is desirable that the diameter of the front lens of the taking lens was less than 60 mm. It is also necessary to use a very clear and sharp lenses - anamorphic adapter greatly reduces depth of field (harder to focus), a slightly blurres image, blurred around the edges.
On a full frame spherical aberration is more pronounced, only 3 revision bimetal were devoid of spherical aberration. Blurring at the edges is well suited for close-up portrait photography with a CloseUp filter. It looks like a beautiful wrapping of the picture on the edges of the frame, there is an allocation of the object in the center. Anamorphic adapter with removed chromatic aberrations better than the budget version.
If necessary, the modernization of the anamorphic adapter for working with large diameters of the main lenses and mounting to the 72mm and 77mm filters of the taking lens is discussed.
Most of clarity occurs at a distance of 10 meters to 20 meters. Depending on the optical design of the taking lens at a distance closer than 3 meters may need 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.
This is a prototype of the future lenses, they are has frayed and processing traces. The lenses are clean and no scratches.

Length - 65 mm, diameter - 82 mm, mounting - 67 mm. Weight ~ 180 grams.
The adapter does not have a clamping device included.
Available in 3 pieces
An order for the production of a large number of filters (than available) adds 1 month to manufacture from date of purchase.
You can also order filters with the desired characteristics and diopter.
On eBay is more expensive by shipping, Pre-order-production after order.
