F stop lens7/26/2023 ![]() A wider maximum aperture can also help prevent camera shake and cut back on motion blur as it allows you to use a faster shutter speed. A higher aperture is preferred by portrait photographers, for example, as only the subject is in focus and the background can be blurred to draw the viewer’s attention fully to the subject. The lower the f-number, the shallower the depth of field. F-stops are generally written like this: f/2.8, f/4, f/5.6, etc., and can span a range from around f/1.2 to f/32 (though there are some lenses that allow for even more extreme apertures). For one thing, the aperture size directly impacts depth of field. A camera’s f-stop corresponds to the size of a lens’s aperturethat is, the size of the hole in the lens that lets in light. The maximum aperture of a camera can really impact the type of photos you can produce and lenses with a wide maximum aperture has definite benefits. Some cameras support f-stops up from f/1.4 down to f/32. f/11, f/16, f/22 There are other f-stops, of course. It is the commonly seen aperture range in many lenses. The typical range of f-stops a camera supports is f/1.8 f/22, consisting of the following f-stops: f/1.8, f/2.0, f/2.8, f/4, f/5.6, f/8. For example, in the chart above f/1. In this f stop chart infographic, I have listed aperture values from f2.8 to f22. ![]() ![]() The wider the aperture the opening in the lens the smaller the f-number. The Maximum Aperture is always included in the naming convention of the lens, for example EF24-70mm F.2.8L II USM. F-stops (also referred to as f-numbers) refer to how open or closed the opening in your lens is. Basically, it is the hole in your lens with the largest diameter, allowing the most amount of light to travel through the lens to the film plane. I’m not going to bore you with the math behind F-stops. The aperture size is controlled by the FStop setting on your camera. So with a 200mm focal length, an f/4 aperture has a diameter of 50mm (i.e. The aperture is the device controlling the opening inside the lens. What the f-stop number refers to in fact is the width of the aperture opening - and you get this by dividing the focal length of the lens by the f-number. ![]() The maximum aperture - expressed in f-numbers or f-stops (for example f/2.8) - is the limit to how wide a lens can be open. 1 Using F-stop for exposure The FStop is the actual opening of the lens. ![]()
