Experience of high quality extended Nikon z-port range extender tc-1.4×2.0x

In July 2020, Nikon released two photography accessories of z-bayonet, z-augmented mirror tc-1.4x and 2.0x, which can expand the focal length of 1.4x and 2.0x respectively, and will not compromise in image quality, focusing and anti shake after installation. This time, the “big three yuan” telephoto lens of Nikon Z series, Nicole Z 70-200 mm f / 2.8 VR s lens, is also the only lens product of Nikon Z series that has been compatible with range extender. < / P > < p > in fact, it is not difficult to understand the use and demand of augmented mirrors. If you already have a lens with a size of 70-200 mm, the longest focal length of 200 mm will be difficult for birds, lotus, aviation and other subjects that need extra long focal ends. The cost of buying an extra telephoto lens is obviously much more expensive than purchasing an augmented lens, and carrying two telephoto lenses at the same time will bring a burden on travel. Therefore, the augmented lens has become a good choice to expand the focal length by using the existing lens in hand. According to the needs of different subjects, different augmented lenses can be selected flexibly. < / P > < p > Z range extender tc-1.4x is composed of 4 groups of 6 lenses, including one aspheric lens with a weight of 220g, a size of 72mm x 18.5mm, and a total length of about 37mm; the z-extender tc-2.0x consists of five groups of eight lenses, including one aspheric lens, weighing about 270g, with a size of 72mm x 32.5mm and a total length of about 50.5mm. After installation and use, in addition to the overall length will be slightly increased, but the overall holding center of gravity and weight will not have any impact. < / P > < p > the performance of the main lens is fully used in the optical design of the two z-augmented mirrors, and the various aberrations that may occur when using the augmented lens are reduced as much as possible. Even if the image is cropped, good rendering performance can be maintained. In the real shooting, thanks to the optical performance and auto focusing performance of the main lens Nicol Z 70-200 mm f / 2.8 VR s, there is no loss of focusing sensitivity, anti shake performance and image quality when using Z range extender tc-1.4x and 2.0x. < / P > < p > in addition, since the closest focusing distance will not be changed after the range extender is assembled, the magnification can also be increased according to the magnification, which brings a certain macro range capability. The maximum magnification of Nicol Z 70-200 mm f / 2.8 VR s changed from 0.2 times to 0.28 times after using tc-1.4x, and from 0.2 times to 0.4 times with tc-2.0x. < / P > < p > for urban scenery shooting, the space compression brought by longer focal length can bring stronger visual effect and stronger perspective sense. When shooting aircraft, lotus and other subjects that can not be closely contacted, longer focal length can shoot more details, and obtain a longer view angle, which greatly expands the focus of 70-200 mm in the hand. < / P > < p > in general, no matter from the perspective of image quality and convenience of use, Nikon Z range extender tc-1.4x and 2.0x are the best choice for Nikon Z bayonet users. It is worth mentioning again that by the time of publication, nikonnikonair Z 70-200 mm f / 2.8 VR s lens is the only lens that can use these two types of telephoto lens at present. We also expect Nikon to bring more telephoto lenses for Z system in the future, and bring more extreme ultra long focus experience with zoom lens.
