Ask some literal meanings of Canon lens.

1, life size? Converte, this is a close-up shot, which is installed between the fuselage and the lens to increase the magnification.

2.TS-E series is Canon's shift lens, and its lens can change the inclination and offset, thus changing the focal plane and optical axis. This kind of lens is widely used in architectural photography, and now it is also used in portrait photography to obtain a visual effect different from that of portrait lens.

3, MP-E65mm is Canon's macro lens with the highest magnification, with the highest magnification of five times! But the general macro header only has the ability to enlarge 1 times.

4. Extender? EF? Series II, Canon's rangefinder, is installed between the fuselage and the lens to obtain a longer focal length. 1.4X means to increase the focal length of the original lens by 1.4 times, and 2X means to increase it by 2 times. ?

Supplementary answer:

The scientific name of this life-size Converte should be: the original size converter, designed by Canon for a 50mm lens, can reach 0.5 times magnification, so it has always been called a close-up lens. The quality is quite excellent, but Canon later found that it can be used on almost any lens of Canon EF bayonet, which threatened the market of macro head, so Canon immediately stopped production. Attach a life size? Converte's photo.
