What are the shots of the big three yuan and the small three yuan of C family?

The so-called big ternary refers to Canon's three red circle L zoom lenses, covering the f2.8 constant aperture of the most commonly used focal length, including:

16-35mm f2.8

24-70mm f2.8

70-200 mm f2.8 is L (the mirror is white, also known as "Ai Xiaobai", isxb, and its latest version has ISIII second-generation anti-shake, so it is also known as "Ai Xiaobai").

The so-called small ternary means that Canon's three red circle L zoom lenses cover the constant aperture of F4' s most commonly used focal segment, including:

17-40mm f4 length

24-105mm f4 length

70-200 mm f4 is L (also white, commonly known as "I love Guo Xuwei", which is xxb,).

"Xiao Sanyuan" provides a choice for photographers who like portability and have limited funds in terms of aperture, convenience and price. Compared with its big brother "Da Sanyuan", the weight and price of this combination are 40%-50% less. Of course, a smaller aperture has a certain influence on the image quality. With the continuous improvement of SLR high ISO and IS interview technology, I believe more people will choose this combination.
