focal reducer

A focal reducer is an optical device used primarily in photography and astronomy. It reduces the effective focal length of a camera lens or telescope, allowing for a wider field of view and brighter images. By shortening the focal length, it also enhances the depth of field and can make a system more versatile for capturing expansive scenes or celestial objects. Essentially, it helps users get more in their shot and can improve the performance of their equipment, making it valuable for both amateur and professional enthusiasts.
