The lens speed of a high-speed camera differs from that of a regular camera in terms of the maximum aperture size and the ability to transmit light. High-speed cameras are designed with larger maximum apertures, allowing for more light to enter the lens and reach the sensor. This increased light transmission is essential for capturing fast-moving subjects with clarity and detail.
Regular cameras, on the other hand, typically have smaller maximum apertures, limiting the amount of light that can reach the sensor. This can result in slower shutter speeds and potential motion blur when capturing fast-moving subjects. Additionally, high-speed cameras are often equipped with advanced lens coatings and optical elements to minimize distortion and aberrations, ensuring high-quality images even at high frame rates.
Overall, the lens speed of a high-speed camera is optimized for fast action photography, offering superior light transmission and image quality compared to a regular camera.
