| MF curve |
 |
The MTF curve provides a reference for lens sharpness and contrast, which is professional and scientific. At first glance, it makes people dizzy, but in fact, it is not difficult to understand it.
The horizontal axis of the chart from left to right represents the distance from the center to the edge of the lens. The unit is mm. If the matching camera is APS-C format, it is usually enough to see 15mm. If the camera is full format, it is enough to see 20mm.
The vertical axis of the icon represents the performance of the camera. In terms of rough division, 0.8 or more is good, 0.6-0.8 is average, and 0.6 or less is bad. You can understand it as a child's exam score, with a full score of 100 or less.
Then there is the curve of thick, thin, virtual and real: thick lines (ignoring the virtual and real first) represent contrast, that is, the degree of clearness between black and white, from left to right represents the contrast performance of the lens from the center to the edge, thin lines represent sharpness, that is, the degree of image clarity, and from left to right represents the sharpness performance of the lens head from the center to the edge.
The dotted line needs to be seen together with the solid line of the same color and thickness. The closer the two lines are, the more beautiful the scattered mirror of the lens is, and the transition from in focus to out of focus is more natural.
Black represents the performance at the maximum aperture, while blue represents the performance at f/8. Generally, the picture quality at the maximum aperture of the lens is not the best. A slight contraction of one or two gears will lead to better performance.
The MTF curve is a rigorous scientific reference, which only provides a reference medium for everyone, but some things cannot be reflected by it. The MTF curve of some lenses may be plain, but the shooting effect is amazing. The lens is not only the product of optics, but also the accumulation and inheritance of the experience of generations of craftsmen. Each has its own characteristics, It is worth playing and understanding with your heart, and your photography skills and understanding of photography will also rise accordingly. |
|
 | Wide angle zoom lens
Canon EF 16-35mm f/2.8L II USM lens has a wide perspective, which is very suitable for landscape and architectural photography, and can also take into account the needs of some humanistic photography.

|
 | UD (ultra low dispersion) lens
The lens set of Canon EF 16-35mm f/2.8L II USM lens includes two UD (ultra-low dispersion) lenses, which are characterized by low refraction and low dispersion. Two UD lenses can obtain the chromatic aberration compensation performance equivalent to one fluorite lens, effectively improving the image quality of the lens.
|
 | Aspherical lens
The lens set of Canon EF 16-35mm f/2.8L II USM lens contains three aspherical lenses. The aspherical lenses manufactured by precision technology can effectively compensate spherical aberration, restrain the distortion of wide-angle lens, and make the shooting picture more realistic. At the same time, it makes the lens design more compact and portable.
|
 | USM ultrasonic focusing motor
Canon EF 16-35mm f/2.8L II USM lens is equipped with a USM ultrasonic focusing motor, which brings you a quiet and high-speed focusing effect. The focusing ability will not be reduced due to the different grades of the body, and the focusing performance will be consistent.
|
 | Full time manual focusing
Canon EF 16-35mm f/2.8L II USM lens has a full-time manual focusing function, which can rotate the focusing ring at any time to switch from automatic focusing to manual focusing. It allows you to quickly and independently change the focusing distance, providing more space for free creation. (See the instructions for specific use methods)
|
 | Rear focus/internal focus
Canon EF 16-35mm f/2.8L II USM lens adopts the rear focus/internal focus design, which can make the lens design more compact, and the front end of the lens will not rotate when focusing, so it is more convenient to use the filter.
|
 | Metal bayonet
Canon EF 16-35mm f/2.8L II USM lens adopts metal bayonet to reduce abrasion of bayonet in long-term use and make the lens more durable. |
 |
Waterproof and dust-proof structure
Canon EF 16-35mm f/2.8L II USM lens uses rubber gasket to fill the gap between the lens and the body interface, and also takes corresponding measures at the active parts such as the focusing ring, which has practical waterproof and dustproof performance and enhances the adaptability of the lens to the environment. (Although this product has certain waterproof performance, please try not to wet it when shooting in rainy days.) |
