Focal length is a fundamental specification of every Lens. It is the distance between the optical center of the lens and the plane on which the lens can focus on the subject, ie where they intersect the light that passes through the lens.
Zoom is the ability of the lens to bring distant objects closer. It is possible to change and adjust the focal length of the lens. The closer your subject is (shooting at a longer focal length), the more it reduces the aperture and the more likely it is for the final image to be affected by camera shake.
Memory cards are the medium on which images and videos are stored. Cards can be chosen by type, capacity, writing speed and brand.
Raw is a high-quality lossless image format supported by professional and semi-professional cameras. This format can be used in special editing software to edit sharpness, saturation and contrast without a reduction in the quality of the resulting image quality.
Rresolution indicates the number of pixels that make up the resulting images. It affects the quality and size of the picture when printing. Generally, the larger the resolution, the better the image quality and the larger the possible print size.
SD cards are a storage medium used in digital cameras, mobile phones and other devices. The name is an abbreviation of Secure Digital. When choosing a memory card, consider the type, capacity and speed you need...
SDXC cards are a storage medium used to store data in digital cameras, camcorders, mobile phones and other devices. Like SDHC cards, they feature technology based on SD memory cards, but they have a higher capacity.
Lens speed (f), indicates how much light the lens is capable of shooting to render the subject. It is the ratio of the diameter of the aperture input and focal length.
