Speedboosters
Speedboosters are optical adapters that modify the image circle projected by a lens, making it compatible with a camera sensor of a different size. This allows photographers and filmmakers to use lenses designed for larger sensor cameras on smaller sensor cameras, such as Micro Four Thirds or APS-C cameras.
Focal Length Conversion
Speedboosters alter the focal length of a lens, effectively “speeding it up.” This is achieved by using a set of optical elements that magnify the image circle projected by the lens. The magnification factor, typically expressed as a decimal, indicates the extent of the focal length change.
For example, a 0.71x speedbooster will reduce the focal length of a lens by approximately 30%.
Aperture Adjustment
When using a speedbooster, the aperture value displayed on the lens will not accurately reflect the actual aperture of the lens. This is because the speedbooster magnifies the image circle, effectively increasing the light gathering ability of the lens. The aperture adjustment factor is typically provided by the speedbooster manufacturer and is usually the inverse of the magnification factor.
For instance, a 0.71x speedbooster will have an aperture adjustment factor of approximately 1.4, meaning that the actual aperture will be one stop wider than the value displayed on the lens.
Advantages and Disadvantages
Advantages
- Wider Aperture:Speedboosters effectively increase the aperture of the lens, allowing for shallower depth of field and improved low-light performance. For example, a lens with a maximum aperture of f/2.8, when used with a 0.71x speedbooster, will have an effective aperture of f/2.
- Wider Field of View:Speedboosters can increase the field of view of a lens, providing a broader perspective for landscape photography or video shooting.
- Greater Reach:By reducing the focal length of a lens, speedboosters allow photographers and filmmakers to achieve a greater reach without having to use longer lenses.
Disadvantages
- Image Quality Degradation:Speedboosters introduce additional optical elements into the light path, which can potentially degrade image quality, especially at the edges of the frame. The quality of the speedbooster itself plays a significant role in this aspect, with higher-quality speedboosters offering better image quality.
- Increased Size and Weight:Speedboosters add to the overall size and weight of the lens system, making it more cumbersome to carry and use.
- Limited Compatibility:Not all lenses are compatible with all speedboosters. It is crucial to check the manufacturer’s specifications to ensure compatibility before purchasing.
Technical Considerations
Choosing the right combination of Sirui anamorphic lenses and speedboosters is crucial for achieving the desired cinematic look and maximizing image quality. This section explores the technical aspects involved in selecting the appropriate setup for your camera and project.

Choosing the Right Combination
The selection of the lens and speedbooster combination is crucial for achieving the desired field of view and image quality. Consider the following factors:
- Camera Sensor Size:The sensor size of your camera determines the image circle required for the lens. Full-frame cameras require lenses with a larger image circle than APS-C cameras.
- Desired Field of View:The focal length of the lens and the magnification factor of the speedbooster determine the field of view.
- Speedbooster Magnification:Speedboosters are designed to increase the magnification of the lens, effectively reducing the focal length. This allows you to use lenses designed for larger sensor sizes on smaller sensor cameras.
Technical Challenges and Solutions, Sirui anamorphic with speedbooster
Using anamorphic lenses with speedboosters can introduce certain technical challenges, including:
- Image Circle Coverage:Ensuring the lens covers the entire sensor area without vignetting is essential for achieving a clean image. Using a speedbooster that is compatible with your camera sensor size and lens is crucial for optimal image circle coverage.
- Focusing Accuracy:Anamorphic lenses have a unique optical design that can affect focusing accuracy. This can be addressed by using a speedbooster with a built-in focusing mechanism or by carefully adjusting the focus ring on the lens.
- Lens Distortion:Anamorphic lenses are known for their distinctive stretching effect, which can introduce some distortion. Using a speedbooster with a correction factor can help minimize this distortion.
- Chromatic Aberration:Anamorphic lenses can exhibit chromatic aberration, particularly at the edges of the frame. Using a speedbooster with a correction factor can help minimize this aberration.
