In the hand of super telephoto lenses, the starting price of 280 million dong of Canon – VnReview


Officially launched in early September, Canon EF400mm f / 2.8L IS III USM and Canon EF600mm f / 4L IS III USM are the latest versions of Canon's "legendary" super telephoto lenses, replacing for generation II has been nearly 8 years old.

Until now, Canon's super telephoto lens line has always been in the ranks of the most advanced lenses of Japanese camera manufacturers thanks to the integration of a series of advanced technologies and "terrorist" size towards the target. Professional photographer specializing in sports, nature and wildlife. Therefore, their prices have never been pleasant and the "cheap" products have the price up to several tens of millions of dong.

With Canon EF400mm f / 2.8L IS III USM (left) and Canon EF600mm f / 4L IS III USM (on the right), the price of these two lenses is $ 11,999 (VND 280 million) and 12,999 (303 million VND, about 20 million VND higher than life II.

The biggest improvement on Canon's III super telephoto lenses is that the weight has been significantly reduced even though the maximum diameter and length remain equal to the previous one. Accordingly, the EF400mm f / 2.8L IS III USM is only 2.84Kg, 1.01Kg lighter than Generation II. While the EF600mm f / 4L IS III USM is only 3.05Kg, 870g lighter than the previous version. Canon confidently affirmed that these are the two lightest lenses available today in the focal length range of 400mm and 600mm.

According to Canon, changes to the optical design and mechanical structure on both lenses, as well as the combination of fluorite and Super UD lenses helped them to successfully weigh the two super telephoto lenses. . Both lenses also feature Air Sphere Coating (ASC) and Super Spectra Coating (SSC) coating, which helps reduce glare and ghosting.

Experiencing the reality, the writer can completely hold the EF400mm f / 2.8L IS III USM lens with one hand for relatively easy operation without the help of a tripod.

This helps to adjust the frame, view and layout more flexible, very suitable in situations that require high mobility such as event shooting, music …

With the EF600mm f / 4L IS III USM one-handed operation is still possible, but it will be more difficult because of its significantly longer size despite weighing only about 200g.

These two lenses are Canon's first lenses with not only one, but two preset values ​​for focusing adjustment. Users just need to rotate the white playback ring (located behind the function buttons and the front of the focus ring) left or right to move the focus to a preset distance.

Each lens is equipped with an electronic focus ring and a manual focus speed adjustment switch to switch between 3 different focus speed levels. The closest focusing distance of the EF400mm f / 2.8L IS III USM is 2.5m while the EF600mm f / 4L IS III USM is 4.2m (nearly 30cm higher than life II, allowing closer access to the subject).

Improved anti-shake function up to 5 stops (CIPA standard) compared to 3.5 stop life II. Thanks to that, hand-held "sniping" from afar is also easier.

Better anti-vibration is thanks to combining a digital gyroscope sensor and increasing the angle of compensation on the lens.

Both lenses have improvements to the typical white coating of Canon telephoto lenses. Specifically, there is a new, highly reflective, heat-resistant coating in the lens cover, which protects the lens from infrared rays under the sun.

This feature combined with a 2-layer lens ring mechanism further reduces the temperature rise in the lens, and ensures stable image quality even when shooting for long periods of time under intense sunlight. This is a situation that is not uncommon for wildlife photographers.

The lens rims for both lenses also have a dust-proof, light-water-resistant structure, as well as a fluorine coating in the outer and front lenses for easy removal of dirt.

With the EF400mm f / 2.8L IS III USM and EF600mm f / 4L IS III USM, Canon continues to affirm its position in providing high-end imaging solutions, worthy of a reliable choice for photographers. profession.
