Canon Announces EF 200-400 f/4L IS with Professional Telephoto Lens

An old photographer Robert Cappa (a Hungarian Photojournalist and Combat Photographer) says that if your photos are not good enough, you are not close enough. The problem is that there are situations in which it is really impossible to get closer to what you are photographing. It is difficult to explain to the referee of a football game, we need to be in the countryside taking photos not to betray the memory of the photographer. So for these cases, it is one of the best telephoto shooting cameras while we find one, maybe good one.

This is the case of this Canon EF 200-400 f/4L IS. As its name suggests, the focal length ranges between 200 and 400 millimeters, or what the same is, we see things that are far away. It’s not spectacular values in this regard, as many low-end telephoto lenses offer focal lengths similar. Nevertheless, 400-mm focal length is more than respectable. Also, if it falls short, the goal has the ability to electronically expand a little more this value. Through this multiplier 1.4 x, you can reach 560-mm. The issue is how the picture looks real and that is when we started to pull zoom but enough problems usually occur.

The first problem is that we ran out of light when further extend the focal length. The smaller is usually the maximum aperture diaphragm and therefore the light begins to be insufficient. One of the most interesting points of this objective is that the maximum aperture of the diaphragm is fixed, regardless of focal length are using. Moreover, the value is low enough to be a telephoto f4, the first indication that we are dealing professional lens.

Another important point is the chromatic aberration produced by the lens. That is when we use a telephoto, glass construction is particularly important because we only use a small part of this, “the central” and crystal defects tend to be more evident. For this, the Canon EF 200-400mm f/4L IS has a lens constructed (as usual in Canon) with fluorite elements. This allows low scattering of light through the lens, as well as reducing chromatic aberration, typical of these situations.

Another key element is the focus. Canon wanted to include different technologies to improve this section in this telephoto. On the one hand has a fast Autofocus system and ring-type Silent. They have also enhanced the focus during video recording manually or automatically. But can we will use an objective in a professional way, worry also about other aspects that have little to do with the image quality. That is carrying the camera all day and every day, just losing him respect, and this result in bumps and other incidents. Therefore, this lens has an aluminium alloy body resistant to shock, a coating of fluoride glass to “frighten” the dirt, dust and water sealing.

It’s a professional lens, which goes well with high end cameras of the Japanese, like the popular Canon EOS 5D or EOS 1D sophisticated. Still no price or availability details appear in the rumors.
