The wider the aperture of the lens is open, the faster the shutter speed needs to be to get a good exposure. If you took a photo with the aperture set to f/8 and the shutter speed set to 1/30th of a second, to get the same exposure with an aperture of f/2.8, you’d need to...

The f-stop explained. F-stop is the term used to denote aperture measurements on your camera. The aperture controls the amount of light that enters the camera lens, and it’s measured in f-stops. Along with shutter speed and ISO (sensitivity to light), aperture is the third fundamental ...
In the photo below, you can see two different lenses: my Tamron 17-35mm and my Canon 85mm. On the Tamron, you should see “1:2.8-4,” and on the 85mm, you should see “1:1.8.” What does this mean? It’s simple: the maximum aperture on the 85mm lens is f/1.8, and on the...
A wider FOV makes the viewing experience more realistic. But, regardless of the lens used, the angle is always smaller than the field of vision possible with the human eye. In other words, camera lenses cannot deliver the same kind of immersive viewing experiences possible with human eyesight....
What is OIS Camera movements caused by shaky hands or other external factors are among the causes of blurry photos. Optical Image Stabilization (OIS) technology helps minimize blurriness by automatically adjusting the camera lens to counteract minor movements during the exposure. Note: OIS does not ...
