Super cost-effective Korea Sanyang 85mm F 1.4 measured report

IT 168 color evaluation friends who play SLR and like to take portraits must be looking forward to having an 85/ 1.4 lens, but this lens is usually expensive (Nikon 85/ 1.4 asks for 7 1000 yuan, Sony Zeiss 85/1. Recently, however, Sanyang Optics from South Korea has introduced a very low-priced 85mm F 1.4 aspherical IF lens, which costs less than 2,300 yuan, which is undoubtedly full of temptation for countless cash-strapped filmmakers.

This is the 85mm F 1.4 aspheric IF of Sanyang, Korea.

However, does this low price mean that the workmanship and imaging of this lens are the same? Cheap? What about yours? Today, we specially collected a lot of information about 85mm F 1.4 aspheric IF from dc to see if this is one. Available? A portrait mirror with high cost performance.

About sanyang optics;

This is a subsidiary of South Korea Sanyang Technology (founded in 1972), which produces telescopes, rangefinders, night vision goggles, speedometers, monitors and astronomical telescopes in addition to photographic lenses. Besides 85/ 1.4, we also produce 500/8(ED), 650- 1300/8- 16, reflective 500/8, 500/6.3 and 800/8 lenses. Some time ago, the company also released a brand-new 14/2.8 if ed McAsperical and an 8mm fisheye CS lens. It should be noted that so far, the lenses produced by Sanyang Optics for SLR cameras are all focused manually, and the prices are very cheap.

About 85mm F 1.4 aspheric surface IF:

The 85mm F 1.4 aspherical IF is a Quan Huafu lens. It uses seven groups of nine lenses (including two compound aspheric lenses) and eight diaphragm blades. The nearest focusing distance is 1 m, the aperture of the filter is 72mm, and the volume is 78? 72.2mm, weighing 5 13g.

The following is an illustration of this shot:

The diameter of the filter is 72 mm.

There is no electronic function, but there is an aperture linkage.

Can correspond to the Quan Huafu SLR body

The design is very similar to the original nikkor lens, and the rotation range of the focus ring is about 150 degrees.

The lens coating is also the same wrinkle paint as Nikon's original factory, and the aperture adjustment step is 1/2EV.

Gold nameplate, aspheric surface represents aspheric lens, but IF internal focusing structure is of little significance for a manual lens.

Made in Korea, 72 mm caliber.

Installing on Nikon D200 or D300 fuselage can realize aperture priority, but the focusing information is gone.

Formed at F8 aperture

One problem is that the hood can't fit into this lens bag ~ ~ ~

Summary: Sanyang's 85mm F 1.4 aspheric IF lens is soft with perceptible dark angle at the full aperture of F 1.4. The improvement of clarity at F5.6 is very obvious, but it still hasn't reached an excellent level. Of all the above proofs, the only one that is satisfactory in sharpness is the last photo taken under F8. Unfortunately, there are no more proofs or smaller apertures under F8 for reference.

Sanyang 85mm F 1.4 aspherical IF and Nikon D700 are together.

In other respects, the eight aperture blades of the 85mm F 1.4 aspheric IF did not bring attractive performance of scattered scenes, and the background blur effect was somewhat divergent, and most of the spots were lemon-shaped. However, it is worthy of recognition that the dispersion control of this lens is in place, and the purple edge problem is not obvious, and it will only appear in extreme cases.

In addition, it should be noted that the above-mentioned proofs do not include photos that can be used to examine the imaging quality around this lens (there are no brick wall photos, and the aperture values used to shoot the proofs are only F 1.4, F5.6 and F8), so our evaluation of the image quality of the 85mm F 1.4 aspheric IF can be said to be quite incomplete. But only through these samples and our low evaluation, we have to admit that the performance of this lens has far exceeded our previous expectations (mainly considering that its price is only equivalent to 1/3 of other similar products).
