A telephoto lens is a camera lens that is typically used for taking photographs of subjects that are a distance away such as a landscape. They are also used for subjects that the photographer can not get close to such as wildlife, and sporting events. A zoom lens allows the photographer to get very close to the subject matter and then zoom in.
A thick lens has varying thickness across its surface, which affects how light is refracted. A thin lens is assumed to have a uniform thickness, simplifying calculations in optics. Thick lenses can produce more complex optical effects compared to thin lenses.

The lens size is the only difference the XL have a bigger lens.
There is no difference between lense and lens. All is the same.
The main difference between a 1.4 and a 1.8 lens is the aperture size. A 1.4 lens has a larger aperture, allowing more light to enter the camera compared to a 1.8 lens. This means the 1.4 lens can produce brighter images and better low-light performance.
It's about a $300-400 USD price difference.
The pinhole camera has no lens. The human eye has a variable-focus lens.
The main difference between a 35mm and a 50mm lens in Nikon cameras is the focal length. A 35mm lens has a wider field of view, capturing more in the frame, while a 50mm lens has a narrower field of view, ideal for portraits and close-up shots.
simple microscope only have 1 lens and compound microscope uses 2 lens \
Double lens goggles don't fog up as easily and are more durable than single lens.
An EZ lens is a type of lens that is easy to use and typically has a simple design, while an IIR lens is a more advanced lens that uses infrared technology for imaging. The main difference between the two is the level of complexity and technology used in their design.
A concave lens is a lens in which the ends are thicker than the middle, rather shaped like this ---> )( A convex lens is a lens in which the ends are thinner than the middle, shaped like the following ---> ()
