Carls Cinema | Can You Make A Lens Parfocal Using A Speedbooster? @carlscinema7086 | Uploaded September 2020 | Updated October 2024, 1 hour ago.
Can you make your lens parfocal using a speed booster? In this video we put it to the test. The glass element inside a focal reducer can often be rotated to either move it closer to or further away from the sensor. This allows for correction if the lens can't reach infinity focus, but can we use it to make our zoom lens parfocal? Lets find out.
