The f on a camera lens is the maximum aperture of the lens. It is sometimes listed as 1:X with X being the maximum aperture. For example:- Canon EF 50mm f1.4 is a 50mm prime lens with a maximum aperture of 1.4- Tamron 90mm f2.8 is a 90mm prime lens with a maximum aperture of 2.8- Canon 70-200mm f/4 is a lens with a focal length of 70-200mm and a maximum aperture of 4.
The main function of a camera lens is to collect light. The aperture of a lens is the diameter of the lens opening and is usually controlled by an iris. The larger the diameter of the aperture, the more light reaches the film / image sensor.Aperture is expressed as F-stop, e.g. F2.8 or f/2.8. The smaller the F-stop number (or f/value), the larger the lens opening (aperture).
The largest aperture which is the smallest number on the aperture ring/dial generally anything between f1.2 - f5.6 dependant on the lens and zoom. On most consumer digital cameras the more you zoom in the higher the smallest aperture becomes. eg. Lens at 35mm, widest aperture (shallowest depth of field) generally about f2.8 Zoom in and the largest aperture will reduce to about f5.6
The functional opening is the aperture, the opening that controls the amount of light that hits the photosensitive surface. You may have a camera with interchangeable lenses that screw into and out of the camera's body. The opening into which the lens is screwed is not the aperture.
shutter speed and lens aperture
The word aperture does not apply to the lens itself. In a camera, the aperture is the diameter of the shutter opening which allows light to reach the lens.
"Aperture" is a synonym for a break or a crack. "Aperture" is used in many modern day phrases such as camera aperture and of course, "Aperture Science" from the game Portal.
The main difference between a lens with an aperture of f1.4 and a lens with an aperture of f1.8 is the amount of light that can enter the lens. A lens with an aperture of f1.4 allows more light to enter compared to a lens with an aperture of f1.8. This means that the f1.4 lens can produce brighter images and is better suited for low-light conditions. Additionally, a lens with a wider aperture like f1.4 can create a shallower depth of field, resulting in more pronounced background blur or bokeh in photographs.
A lens with an aperture of f 1.8 allows less light in compared to a lens with an aperture of f 1.4. The f 1.4 lens has a wider aperture, which means it can capture more light and potentially produce sharper images with a shallower depth of field.
A lens with a 1.8 aperture will generally produce better image quality compared to a lens with a 2.8 aperture. This is because a lower aperture number allows more light to enter the lens, resulting in sharper images with better depth of field and low-light performance.

A lens with an aperture of f 1.4 allows more light to enter than a lens with an aperture of f 1.8. This means the f 1.4 lens can create a shallower depth of field and better low-light performance compared to the f 1.8 lens.
The maximum aperture of a lens rated at 3.5/5.6 is f/3.5.
Aperture
The aperture range of the camera lens I am using for my photography is f/2.8 to f/22.
The lowest aperture lens available for purchase in the market is typically around f/0.95.
By opening the aperture of the lens, the photographer was able to increase the photo's depth of field.
