Lenses produced for 35 mm film cameras may mount well on the digital bodies, but the larger image circle of the 35 mm system lens allows unwanted light into the camera body, and the smaller size of the image sensor compared to 35 mm film format results in cropping of the image. This latter effect is known as field-of-view crop.
For example, a 28 mm lens delivers a moderately wide-angle FOV on a 35 mm format full-frame camera, but on a camera with a 1.6 crop factor, an image made with the same lens will have the same field of view that a full-frame camera would make with a ~45 mm lens (28 × 1.6 = 44.8). This narrowing of the FOV is a disadvantage to photographers when ...
This is a list of smartphones with a primary camera that uses a 1.0-type (“1-inch”) image sensor or larger. However, as of February 2024, there are no smartphones that use a sensor larger than 1.0-type. The first camera phone to feature a 1.0-type sensor was the Panasonic Lumix CM1 in 2014. Seven years passed before another phone featured ...

This is a list of smartphones with a telephoto lens that offers a focal length (35mm equivalent) of at least 100mm or "4× optical zoom" with an imaging area equivalent to a 1/3.5″ or larger sensor. Smartphone lenses are often marketed in terms of "optical zoom" [1] relative to the phone's main camera. For example, 120mm is usually referred ...
The iPhone 13 and 13 Mini feature the same camera system with three cameras: one front-facing camera (12MP f/2.2) and two back-facing cameras: a wide (12MP f/1.6) and ultra-wide (12MP f/2.4) camera. The back-facing cameras both contain larger sensors for more light-gathering with new sensor shift optical image stabilization (OIS) on the main ...
where N is the uncorrected f-number, NA i is the image-space numerical aperture of the lens, | | is the absolute value of the lens's magnification for an object a particular distance away, and P is the pupil magnification. Since the pupil magnification is seldom known it is often assumed to be 1, which is the correct value for all symmetric lenses.
Drawing showing the relative sizes of sensors used in most current digital cameras, relative to a 35mm film frame. The image sensor of Four Thirds and MFT measures 18 mm × 13.5 mm (22.5 mm diagonal), with an imaging area of 17.3 mm × 13.0 mm (21.63 mm diagonal), comparable to the frame size of 110 film. [4]
