On a digital SLR camera, anything less than about 32 mm (50 mm for a 35 mm film camera). The focal length of a wide angle lens varies depending on the size of the negative or digital sensor. Most camera manuals for smaller cameras will give you an idea for that camera, often in 35 mm equivalents, so use the 50 mm standard for those.
The focal length of a telephoto lens is longer than the focal length of a wide-angle lens. Telephoto lenses have a narrow field of view and are ideal for capturing distant subjects, while wide-angle lenses have a wider field of view and are great for capturing expansive scenes.
The shortest focal length lens available for capturing wide-angle shots is typically around 10-14mm.
The main difference between an 18-55mm lens and an 18-135mm lens is their focal length range. The 18-55mm lens has a shorter focal length range, making it better for wide-angle shots, while the 18-135mm lens has a longer focal length range, allowing for more versatility in capturing both wide-angle and telephoto shots.
That would be a "wide-angle" or a "fish-eye" lens.
Using a camera lens with a low focal length for wide-angle shots offers advantages such as capturing more of the scene in a single frame, creating a sense of depth and perspective, and minimizing distortion at the edges of the image.
Typically a lense of shorter focal length than 35mm. It is called wide-angle because the angle of view is wide, up to 180 degrees for some fisheye lenses.
A telephoto lens is a type of lens that has a long focal length, allowing you to zoom in on distant subjects. A zoom lens, on the other hand, has a variable focal length that allows you to adjust the magnification level, including both wide-angle and telephoto capabilities.
"mm" on a camera lens refers to the focal length of the lens, measured in millimeters. It indicates how much the lens can zoom in or out, with larger numbers representing a longer zoom or telephoto lens, and smaller numbers indicating a wider angle or wide-angle lens.
The main difference between the 18-55mm and 18-135mm lenses is their focal length range. The 18-55mm lens has a shorter focal length range, making it more suitable for wide-angle shots, while the 18-135mm lens has a longer focal length range, allowing for more versatility in capturing both wide-angle and telephoto shots. In terms of performance, the 18-135mm lens generally offers better zoom capabilities and image quality compared to the 18-55mm lens.
The main difference between the 18-55mm and 18-140mm lenses is their focal length range. The 18-55mm lens has a shorter focal length range, making it more suitable for wide-angle shots and general photography. On the other hand, the 18-140mm lens has a longer focal length range, allowing for more versatility in capturing both wide-angle and telephoto shots. This makes the 18-140mm lens more versatile for a wider range of photography situations.
The lens in a door peephole is a convex lens with a very short focal length, giving it a wide field of view. If it were on a camera, it would be called a "Fisheye lens".
A 5-50mm lens is a zoom lens with a focal length range of 5mm to 50mm. It allows you to adjust the focal length within that range, giving you the flexibility to capture a variety of shots from wide-angle to telephoto. This type of lens is versatile and can be used for different types of photography such as landscapes, portraits, and street photography.
