Image stabilization is a technology used in digital cameras and lenses to reduce blur caused by camera movement. There are different types of image stabilization, including optical, electronic and image stabilization on the sensor (IBIS). Each type has its advantages and disadvantages, but all aim to improve image quality when shooting handheld or at low shutter speeds.

A bayonet is a type of mechanical connection used to attach the lens to the camera body. The type of bayonet determines which lenses are compatible with a given camera. Different makes and models of cameras may use different types of bayonets.

Sensors (chips, sensors) of digital cameras record video information when photographing an object and then send it to the processor. According to the manufacturing technology they are divided into...

The size of the sensor determines how much light falls on the chip. 

Resolution indicates the number of pixels that make up an image or video. A lot of modern devices are equipped with Full HD resolution (1920 x 1080), which is suitable for display on large screen TVs or monitors. Higher resolution provides smoother images with more detail.

Compact cameras usually have an aspect ratio of the sensor 4:3, powerful equipment can have 2:3 or 3:2. Available are also variations, such as 16:10, 16:9, 5:4, etc.  

Minimum time that the shutter is open, allowing light to strike the image sensor. Fast shutter speeds are used for taking quick action shots to capture sharp images.

The maximum time that the shutter is open, allowing light to strike the image sensor. Slow shutter speeds are used for a variety of shots with special effects or with targeted out of focus images.

ISO specification indicates the camera sensor's sensitivity to light. Higher sensitivity is primarily used in low light conditions to avoid unwanted noise and blur.

Sekvenčné snímanie predstavuje fotografický záznam deja zachytený v sérii snímok idúcich za sebou. Využitie nájde najmä pri fotografovaní rýchlej akcie a športu. Bežné digitálne fotoaparáty dokážu snímať v rýchlosti 2 – 3 snímky za sekundu, výrazne lepšie na tom budú digitálne zrkadlovky, najrýchlejšie sú všeobecne bezzrkadlovky.

Resolution refers to the number of pixels of one frame of the movie. It affects the video quality during playback or editing. 

Video sound reinforcement is the process of recording sound when making a video. The type of sound that is recorded can have a significant impact on the overall quality of the video. Different types of video sound reinforcement include mono, stereo and surround sound. These types of sound offer different levels of sound depth and spatial orientation that can enhance the video viewing experience.

Lenses for cameras vary based on several different factors, including type, construction, focal length, and maximum aperture. The two basic types of lenses are fixed focus (prime) and zoom. Fixed lenses have a single focal length and are generally considered to be able to provide sharper and clearer images than zoom lenses. Zoom lenses allow you to vary the focal length and thus adjust the level of zoom in or out.
