The minimum and maximum distance required for capturing clear images with a specific lens angle can vary depending on various factors, such as the type of lens, aperture, and focal length. A general rule of thumb is that the shorter the focal length, the closer you can get to the subject while still maintaining sharp focus. However, this also means that the depth of field will be shallower, which can result in more blur in the background. Conversely, a longer focal length will allow you to capture images from a greater distance but may result in a narrower field of view.
To determine the minimum and maximum distance required for capturing clear images with a specific lens angle, you can use a depth of field calculator, which takes into account the aperture, focal length, and other relevant factors. By entering these parameters, you can determine the hyperfocal distance, which is the distance at which everything from half of that distance to infinity will be in focus. This can help you ensure that your subject is in sharp focus and that the background is blurred appropriately.
