Filming widescreen like in the cinema - for spherical and anamorphic lenses
With the SIRUI 1.25x anamorphic adapter, you widen the shots of your lenses without any loss (cropping) in height and, with spherical lenses, you get the typical characteristics of a true anamorphic cinema lens, such as backlight effects and lens effects (flares) and oval bokeh.
When using a spherical lens (non-aspherical), you will achieve approx. 16:9 at 4:3 and approx. 20:9 at 16:9 with the SIRUI 1.25x adapter.
When using an anamorphic lens, the squeeze factor of the lens is multiplied by the squeeze factor of the SIRUI 1.25x adapter. This means that 1.6X becomes 2.0X and 1.33x becomes 1.66x.
The adapter can be used on lenses with 67, 72, 77, 82 and 92mm filter threads. It has an 82mm male thread for direct connection to lenses with an 82mm filter thread. The scope of delivery includes three step-down rings 82 -> 67mm / 82 -> 72mm / 82 -> 77mm and one step-up ring 82 -> 92mm.
The adapter itself has an 82mm filter thread at the front.
The SIRUI adapter is equipped with a manual focus. The possibly existing autofocus of your lens must be deactivated and set to infinity, Then the focus is controlled manually via the adapter. The adapter is equipped with a gear ring for follow focus systems.
With anamorphic lenses or adapters, the image will be squeezed in width (squeeze). A camera with de-squeeze function or a monitor with de-squeeze function is required for viewing.
