Comparison between Canon 16-35 and 17-40

Canon short lens 16-35mm is better, but it is a little different when taking amateur photography. It is best to choose 16-35mm lens.

First, the price difference doubles, and 16-35mm is expensive.

Second, there are 16-35mm lenses, 12 lenses, and 17-40mm lenses with only 9 lenses. It may be better to correct the wide-angle end if there are more, but it also depends on the quality of each piece.

Thirdly, the lens aperture of 16-35mm is slightly larger, 82mm, and 77mm of 17-40mm. The larger the aperture of the lens, the greater the luminous flux. Therefore, the maximum aperture of 16-35mm is F/2.8, while the maximum aperture of 17-40mm is only F/4.

Generally speaking, as a wide-angle lens, 16-35mm has better performance, but it is also much more expensive.

Extended data

Canon 16-35 and 17-40, in terms of use, wide-angle lenses are suitable for shooting landscapes and buildings, but many people shoot humanities and the effect is good. Because the wide-angle perspective is spectacular and atmospheric, photographers always need a wide-angle lens.

Another thing to say is that 16-35mmF4 has four levels of anti-shake, which is very practical. Comparing F4 with F2.8 in dark environment, F2.8 is of course reliable, but F4 has done level 4 anti-shake, even if the shutter slows down, there is anti-shake compensation, which is also conscience.

Usually, 16-35mmF2.8 is the first choice for shooting starry sky, and the starry sky theme is very special, which requires a large aperture and wide angle, which is incomparable to 16-35mmF4, but the advantages of F2.8 cannot be completely overwhelmed by F4 in daily shooting.

The aperture of 17-40 is only F4.0, which is not good in weak light. And documentary photography, many of them are in poor light environment.

There are two 16-35mm. The aperture of F4.0 is too small, and the aperture of F2.8 is too heavy, so it will be different to hang 80D, because this 16-35mmF2.8 was originally used in Quan Huafu.

If it is a full-frame camera, 16-35mmF2.8 will do. Therefore, if a super wide-angle lens is needed, a Longteng 10-24mm lens can be considered, which is equivalent to a focal length of about 16-35mm when used for 80D.
