Canon, which telephoto L lens is good and cheap?
This is a high-performance L-class telephoto zoom lens with excellent portability. Based on the widely acclaimed EF 70-200mm f/4L USM, a high-performance hand shake compensation mechanism, namely image stabilizer, is added to achieve higher mobility. The relatively small lens aperture design not only enhances the portability of the lens, but also inhibits all kinds of aberrations caused by the lens aperture size from the design aspect. In addition, using 1 fluorite lens and two UD (ultra-low dispersion) lenses which can effectively compensate the residual chromatic aberration, high image quality can be obtained in line with L-class lenses. Among them, fluorite lens can not only effectively compensate chromatic aberration, but also make great contribution to the miniaturization of the whole mirror body. The resolution of the whole picture is uniform and the picture quality is very stable. Full-color performance inherits the tradition of L-level lens. The effect of hand shake compensation mechanism is that the image stabilizer is equivalent to increasing the shutter speed by about 4 levels. When using the tripod, the state of the lens can be automatically detected, so you can shoot safely without turning off the switch of the IS image stabilizer. Hand shake compensation modes can be divided into "mode 1" suitable for ordinary shooting and "mode 2" suitable for follow-up shooting. Even if it is used with APS-C EOS digital SLR camera, it has a good balance in volume and weight, and can obtain a viewing angle equivalent to 1 12-320mm, which can enlarge and shoot a farther subject.
