Canon's Top Ten Conscience Lens

Canon's top ten conscience shots are as follows:

1, EF 200mm mm f/2.8L type II USM

Canon EF 200mm f/2.8L II USM lens adopts a simple lens structure of 7 groups and 9 lenses, and two large UD lenses are added to it, which can obtain a higher chromatic aberration compensation effect equivalent to that of 1 fluorite lens, which has an obvious effect on improving the resolution. At the same time, 136.2mm is more convenient for photographers to carry.

2.EF 100mm f/2.8L is a USM macro.

Canon's EF 100mm f/2.8L IS USM macro lens is upgraded to 12 lens group of 15 lens compared with the previous generation Budweiser. The biggest difference is the addition of IS stabilization system, which is also a very important function for macro photographers, equivalent to about 4 shutters at most.

3. EF 70-300mm f/4-5.6L is USM.

In terms of parameter configuration, Canon EF 70-300mm f/4-5.6L ISU lens adopts the optical structure of 14 sets 19 pieces. Although it is not a constant aperture lens, Fat White is equipped with IS optical anti-shake system, which can reduce the shutter speed by four levels, lighter and smaller than Xiaobai's, and is also very portable.

4、EF 35mm f/ 1.4L II USM

EF 35mm f/ 1.4L II USM lens adopts 1 1 lens structure, including 1 aspheric lens, 1 ground aspheric lens, 1 UD lens and SWC sub-wavelength structure coating, which ensures the highest standard of image quality.

5, EF 50mm mm f/ 1.2 liter USM

In terms of lens structure, Canon EF 50mm f/ 1.2L USM lens is designed in 6 groups with 8 pieces. The lens configuration includes/kloc-0 aspheric lenses, which ensures the reliability of image quality and the correction of slight distortion. The biggest highlight of the whole lens is the super-large aperture of F 1.2, which can get twice the result with half the effort for background blur or dark light shooting at night.

6、EF 85mm f/ 1.2L II USM

EF 85mm f/ 1.2L II USM adopts 7 groups of 8-piece simple lens structures, and the simple structural design also ensures the optical quality better. At the same time, the third lens adopts a thick aspheric lens with large aperture and high precision on the ground, which can effectively suppress spherical aberration. It should be said that there is no big weakness except the large volume of the whole lens.

7. ef11-24mm f/4L USM

Canon EF 1 1-24mm f/4L USM adopts a set of 1 16 optical structures, including four aspheric lenses, a super UD lens and a UD lens. The addition of UD lens can better control the color difference and purple edge effect, and the three-sided aspheric mirror can control the distortion of wide-angle end to the greatest extent.

8、EF 16-35mm f/2.8L III USM

In terms of lens structure, EF 16-35mm f/2.8L III USM adopts the lens structure of 1 1, which is one more set than the previous generation. At the same time, the use of special lenses is more cordial than the previous generation. 1 and the second lens adopts large-caliber GMo (glass casting).

9. EF 24-70mm F/2.8L Type II USM

The fine structure of the 24-70mm second-generation lens adopts 65,438+03 groups of 65,438+08 lenses, among which 65,438+0 ground aspheric lenses and 2 GMo aspheric lenses are added, which can greatly correct the wide-angle end distortion. At the same time, 1 ultra-UD lens and two UD lenses are added, which can compensate the chromatic aberration of the lens well.

10、EF 100-400mm f/4.5-5.6L IS II USM

In the newly designed 16 group 2 1 lens structure, ef100-400mm f/4.5-5.6 l is ii USM adopts fluorite lens and super UD lens, which not only reduces the chromatic aberration in all focal lengths from 100mm to 400 mm, but also ensures the imaging quality of the lens. The resolution and contrast performance of the lens have been greatly improved compared with the first generation products.
