In simple language, a DSLR is a digital camera that uses a mirror mechanism to either reflect light from a camera lens to an optical viewfinder (which is an eyepiece on the back of the camera that one looks through to see what they are taking a picture of) or let light fully pass onto the image sensor (which captures ...

A tilt shift lens allows the photographer to change the position of that imaging circle. By tilting the lens, you change the center of that imaging circle, which can straighten the lines that appear to converge in the distance.

Found on DSLR cameras, an optical viewfinder (OVF) allows a photographer to compose a shot while seeing exactly what the lens sees by looking through the lens (TTL). This optical viewfinder works by using a system of mirrors and prisms, like a periscope, to bounce the image up to the viewfinder and the eye.

A twin-lens reflex camera (TLR) is a type of camera with two objective lenses of the same focal length. One of the lenses is the photographic objective or "taking lens" (the lens that takes the picture), while the other is used for the viewfinder system, which is usually viewed from above at waist level.

What is the difference between DG and DC lenses? The designation DG indicates that the lens has been optimised for digital SLRs but is equally compatible with film SLR cameras. ... DC lenses are designed specifically for digital SLRs with the small, APS-C size image sensor.

Optical zoom means that the camera uses its own optics — or lenses — to magnify an image (as opposed to digitally magnifying the image). ... An optical zoom lens works the same way as any other lens, except it has a system with moveable glass pieces that can shift around to give the lens different focal lengths.

There's another minor challenge to using old film lenses on a modern digital camera: the sensors in digital cameras have glass in front of them, but film didn't. The glass changes the path of the light just a tiny bit, and means that lenses designed for film can't give their best on digital cameras.

Image stabilization basically counters the camera shake you get from holding the camera, making it so you can use slightly faster shutter speeds than without it. Non-VR lenses do not have this feature, but cost less than VR lenses.

The Nikon FTZ is a lens mount adapter that lets us use any F-Mount Nikon SLR or DSLR lens with varying extents of usefulness on Nikon's full-frame mirrorless cameras. FTZ means F to Z, or Nikon F (SLR & DSLR) mount to Nikon's new mirrorless Z mount.

A digital camera takes light and focuses it via the lens onto a sensor made out of silicon. It is made up of a grid of tiny photosites that are sensitive to light. Each photosite is usually called a pixel, a contraction of "picture element". There are millions of these individual pixels in the sensor of a DSLR camera.

A DSLR does not have zoom. It has a lens. The lens may be wide, it maybe tele (long). It might even have a zoom from 1 focal length to another.

Camera Blur Camera blur simply means that the camera moved while the image was being taken, resulting in a blurry photo. The most common cause of this is when a photographer mashes down the shutter button because they are excited. ... So if you're using a 100mm lens, then your shutter speed should be 1/100.

In photography, a lens hood or lens shade is a device used on the front end of a lens to block the Sun or other light source(s) to prevent glare and lens flare. Lens hoods may also be used to protect the lens from scratches and the elements without having to put on a lens cover.

Image focusing: Human and camera lenses both focus an inverted image onto light-sensitive surface. In the case of a camera, it's focused onto film or a sensor chip. ... On a camera, it's done with the aperture control built into your lens, whilst in your eye, it's done by having a larger or smaller iris.

Leica R lenses are 35mm manual focus lenses that fit on Leica R SLR bodies. Most the lenses can be used on any Leica reflex camera body in a non-metered mode (they physically fit onto the body).

What is a DSLR? DSLR stands for digital single-lens reflex. It's the camera of choice for pro photographers and experienced amateurs alike.

The iris together with the pupil act like the shutter and aperture of the camera, controlling how much light filters through. The eye's lens and cornea work on the same principle as the system of lenses in the camera and help to refract and focus light onto the retina or the light-sensitive medium.
