The f/4 aperture is a moderate aperture setting commonly found on camera lenses, representing a balanced opening that provides good depth of field while still allowing reasonable light entry. The f/4 aperture is one stop narrower than f/2.8, meaning it allows half as much light, but it provides greater depth of field. F/4 is a common maximum aperture for many zoom lenses and some prime lenses.

Converting f/4 to other f-stop values helps photographers understand aperture relationships and exposure settings. F/4 is wider than f/5.6, f/8, and other f-stops, allowing more light to enter while providing good depth of field control. Whether you're comparing f/4 to other f-stops for exposure settings, understanding f/4 aperture characteristics for photography, or using an f-stop converter for photography calculations, f-stop conversions are fundamental to photography exposure measurements.

The f/4 aperture is used in photography for various applications where good depth of field is desired along with reasonable light-gathering ability. Many zoom lenses feature f/4 maximum apertures, providing a good balance of performance, size, and cost. The f/4 aperture's moderate opening makes it useful for landscape photography, group portraits, and situations requiring good depth of field.

The f/2 aperture is a wide aperture setting commonly found on camera lenses, representing a large lens opening that allows substantial light to enter. The f/2 aperture is one stop narrower than f/1.4, meaning it allows half as much light, but it's still considered a wide aperture. F/2 lenses provide good light-gathering ability while often being more compact and affordable than wider aperture lenses.

Converting f/2 to other f-stop values helps photographers understand aperture relationships and exposure settings. F/2 is wider than f/2.8, f/4, and other f-stops, allowing more light to enter while creating moderate to shallow depth of field. Whether you're comparing f/2 to other f-stops for exposure settings, understanding f/2 aperture characteristics for photography, or using an f-stop converter for photography calculations, f-stop conversions are fundamental to photography exposure measurements.

The f/2 aperture is used in photography for low-light situations, portrait photography, and artistic effects. Many camera lenses feature f/2 maximum apertures, providing good light-gathering capability and the ability to create shallow depth of field. The f/2 aperture's wide opening makes it useful for indoor photography, portrait work, and situations requiring good low-light performance.
