A varifocal lens is a camera lens with variable focal length in which the focus shifts as the focal varies, as opposed to a parfocal (“true”) zoom lens, which maintains focus while the lens zooms.
When it comes to fixed-lens cameras in particular, many so-called “zoom” lenses are actually varifocal lenses, which offer lens designers greater freedom when making trade-offs in optical design (focal length range, maximum aperture, size, weight, and cost) than parfocal zoom.
These can be used in still photography where the subject’s magnification changes thanks to autofocus and the camera processor’s ability to automatically adjust the lens to maintain it in focus while changing focal length.
The Global Varifocal lens market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
The launch of two new lenses by Canon in India has increased the number of RF lenses available.
For the EOS R line of mirrorless cameras, the business has introduced the RF24mm F1.8 Macro IS STM and RF15-30mm F4.5-6.3 IS STM lenses. Both lenses have the large diameter and quick back focus that the EOS R camera system is renowned for, creating a compact optical system and a uniformly high level of image quality.
The RF24mm prime lens and the RF35 mm lens are about the same size. This makes it a terrific alternative for vacation and scenic photography, claims the firm.
The lens becomes a 38mm l lens when attached to an APS-C sensor camera, making it a strong option for street and portrait photography.Additionally, the lens has built-in image stabilisation that can reach 6.5 stops and work for up to 5 stops.
