What does f mean on a camera lens?
focal length
The “f” in f-stop stands for the focal length of the lens. While focal length itself refers to the field of view of a lens, f-stop is about how much light you allow to hit the sensor via the aperture opening.
What is a focus by wire lens?
Focus by wire or electronic focus means that the focusing lens element is not mechanically coupled with the focus ring on the barrel. Instead, electronic signals from the autofocus system or the focus ring is received by the element to move up and down the barrel to achieve focus.

Is higher or lower f-stop better?
The lower the f-stop, the less depth of field and the blurrier the background. Increase the f-stop, and you’ll get a greater depth of field and sharper background as a result. Discover photo tips and tricks as you begin experimenting with various aperture settings.
Why are mirrorless lenses focus by wire?
Focus by wire or electronic focus has better autofocus performance because the elements are not coupled to the mechanics of the outer barrel. There is less resistance for the motor to work against. It means that the lens can shift focus from one spectrum to the other almost instantly.
What is focus throw?
Focus throw is measured in degrees and represents the amount of rotation needed to turn a lens’s focus ring from its minimum focus distance (which is the closest it’s able to focus) to infinity (which is as far as it’s able to focus).
What size lens is best for landscape?

What focal length is iPhone?
In addition, the iPhone has a rear-facing camera, often used for selfies, that Apple now calls the TrueDepth camera. It has a focal length of 2.87 mm but neither Apple nor third-party reviews list the full-frame equivalent for this lens. With the wide-angle lens, you have an almost limitless depth of field available.
What f-stop makes background blurry?
Choose a Wide Open F-Stop
A very large part of a blurry background is caused by a wide f-stop like 1.8, 2.8 or as wide as your lens will go be it 3.5 or even 4. The wider your f-stop is, the smaller the depth of field will be. Depth of field is the amount of the photo that will be in focus.
How do I know what f-stop to use?
If someone tells you to use a large aperture, they’re recommending an f-stop like f/1.4, f/2, or f/2.8. If someone tells you to use a small aperture, they’re recommending an f-stop like f/8, f/11, or f/16. As you can see, an f-stop like f/2.8 represents a much larger aperture opening than something like f/16.
What is linear focusing?
With linear focus, the amount of focus movement is constant regardless of the speed at which the focus ring is turned.
What is long focus throw?
A long focus throw means the relative change in focal distance per degree of focus ring rotation, is less. The same can be said for macro lenses as well, since this is a situation where photographers are also often working with very shallow depths of field.
How do you focus a cinema lens?
