Which one has higher quality, diamond wide angle or gold wide angle?

Golden wide-angle (reference price: ￥10200)

The famous golden wide-angle zoom Nikkor 17-35/2.8ED is the flagship of Nikon’s wide-angle zoom lenses. This is A very special lens, its imaging quality surpasses that of fixed-focus lenses of the same focal length. It is one of the only three Nikon lenses that uses "cut aspherical lenses". In terms of materials, the AFS ultrasonic motor lens body drive and all-metal lens barrel highlight its high-end positioning. The optical structure is 13 elements in 10 groups including two ED lenses and one aspherical lens, and it is IF internal focusing. Design, the length of the lens remains unchanged during operation. Such a complex structure ensures that the golden wide-angle full-focal section has excellent resolution beyond the fixed focal length of the same level, almost invisible subtle distortion and excellent color reproduction. What kind of praise can be placed on it? Nothing is too much. The deformation at the wide-angle end is very slight and almost invisible.

The highest sharpness of this head occurs at the 25mm segment. At F4 aperture, it surpasses the AF24/2.8D of the same category, and the contrast at all focal lengths is quite good, unlike some old Nikkor heads. , has a tendency to have too high contrast, the color reproduction is very faithful and not exaggerated, but the saturation and details are not bad at all, you can use it as a fixed focus lens. And after using this lens, using other wide-angle zooms will only make people feel like they have been unable to overcome the difficulties.

Diamond wide-angle (reference price: ￥14000)

The first lens of Nikon's "Diamond wide-angle" AF20-35mm f2.8D uses refined and ground aspherical lenses. The use of this kind of lens is very stingy, and only 3 lenses have been favored in total (the other two are Noct-Nikkor 58mm F1.2 and AF28mm F1.4D).

The lens body is made of wrinkle paint, the texture and workmanship are very good, it feels good in the hand, and the weight is moderate (only 585g). Excellent images can be taken at all focal lengths and at full aperture, which is comparable to fixed focus. It is called the "fix focus killer" by some Nikon fans. The sharpness and contrast are very high. The sharpness of the maximum aperture at 20mm is slightly reduced, and there is Slight pincushion distortion, shrinking to 24mm is ideal for distortion control. The head's anti-glare capability is excellent, which has always been Nikon's strength. Although it does not use an ultrasonic motor, the focusing speed is not slow, but the focusing sound is slightly louder. The M/A ring is easy to break, which is also a common problem with early Nikon lenses. Be careful when using it. In addition, the minimum focusing distance is 0.5m, which is a bit far. The 20mm wide angle becomes 30mm on an APS-C format digital SLR camera. , the wide-angle advantage is no longer available, which is one of the reasons why many photography enthusiasts have chosen the "golden wide-angle" AF-S 17-35mm F2.8D ED.
