Nikon 70-300VR has been released for a long time, and its red VR logo indicates that it belongs to the early three-level anti-shake (about equivalent to increasing the shutter speed of the third gear). The materials used for the lenses are kind, and the 17 lenses in the 12 group use two ED lenses, so the color saturation and oiliness can be obtained. Its focusing system also belongs to the advanced full-time manual priority autofocus (after autofocus, you can rotate the focusing ring for manual fine-tuning of focusing). However, cinematographers generally report that the focal length resolution above 200mm is poor, and look forward to the emergence of the upgraded second-generation products.

Longteng SP70-300VC USD(A005) is a key product launched at the 60th anniversary celebration of Longteng. Its design is consistent with the sharp style of Longteng lens. It is equipped with a large USD ring ultrasonic motor newly developed by Longteng and a four-stage VC anti-shake mechanism. It uses a fluorite SLD ultra-low dispersion lens and an ordinary LD low dispersion lens, so the color of the film is saturated and greasy, which is worse than the original Nikon lens. Its traditional high resolution has also been brought into full play, and a clear image can be obtained by completely opening the aperture in the full focus section. It can be described as sharp. Full-time manual priority autofocus and anti-shake to improve the four-speed shutter speed are also slightly better than Nikon's original factory, and the price within 3000 yuan is also very cost-effective. I bought one at the recommendation of a friend, and now it has become my main telephoto zoom lens.
