![]() While prime lenses have a set maximum aperture, some zoom lenses have a variable maximum aperture. Having a lens with a wide aperture will give you more flexibility but it comes at a cost. This is because a wide aperture has a larger opening hole, thus it lets more light in. When browsing for a lens, photographers generally pay attention to the maximum aperture the lens can open up to as it gives an indication of the faster shutter speeds available for the lens to be able to perform in low light scenarios. Photographers might also refer to choosing a wider aperture as ‘opening up’ the lens. So, when considering a wide aperture, we are referring to apertures that open as wide as f/1.2 – f/2.8. The same applies to aperture in photography, where f/2 will create a wider or larger aperture than f/16. The confusion appears because we naturally assume that a ‘large aperture’ will be equal to a larger number.Īn easier way to think about this is to think in fractions. It might appear confusing and it still causes bewilderment amongst photographers at times, that using wide (or large) aperture actually means using a small number, such as f/2.
