Sony's FE system has always been lacking in the relatively low-spec lens and players are always complaining about it. Non-Za, non-GM, “cheap†lenses have so far only four, and the wind rating is not very good:
FE 28-70mm f/3.5-5.6: If it is not 24-70/4ZA it is a bit off the chain, this head is indeed the evaluation of the general dog set. But 24-70/4ZA is not too much stronger than it, but it also makes it have some cost-effective;
FE 28mm f/2: Looks good, but plastic workmanship and edge quality is an eternal slot, and its high cost performance still benefits from the FE 35/2.8ZA's contrast;
FE 50/1.8: It can be said that it is quite a drop. If you buy a Sony system, this specification can be transferred to Canon. It is cheap, it has almost the same picture quality, and it also earns a ring. Either add FE55 directly and the price/performance ratio is better than this one.
The fourth protagonist is today's FE 85mm f/1.8.
Before this lens went on the market, there were only three choices for the original 85mm portrait prime lens of Sony's FE bayonet. The FE 85mm f/1.4GM, which is first-class but expensive and heavy, is a little cheaper, but it is still the same size lens as other homes. Smokey Teng Division (long) Batis 85mm f/1.8, as well as a part-time guest with FE 90mm f/2.8G macro. In fact, for the Sony FE system users whose general budget is not particularly high, it is unacceptable to choose which ones to eat. Although the 85GM is excellent in aperture and large in size but really expensive to smoke, Batis85 is cheaper and there is a blue label, but “only "The f/1.8 specification gave us more doubt when choosing it. Not to mention the FE90, it's just part-time. I want to use it very comfortably and it's too hard for it.
At this time Sony introduced a new non-GM non-ZA-based "cheap" portrait head - FE 85mm f/1.8, before the lens officially launched a sample of the Internet to reflect its quality is good, it is worth buying. So what exactly is the truth? Let's look at it together.
The actual carrying volume of the lens is comparable to the Batis 85, except that the Batis 85 has a larger hood, creating a larger volume of illusion.
One of the two different places is the focus ring position and material. Batis is closer to the mirror tail and is made of rubber matt material. The FE85's focus ring is a metal thread and is closer to the front of the lens.
Another place is the side of the lens (or "feature"). Batis85 has a small OLED display. The FE85 is shabby and doesn't have any information, but there is a shortcut button that can be provided after customization. Some convenient functions (setting eye-control AF on this button is still quite convenient)
The caliber is 67mm, Zeiss's coating extinction ability is relatively better. Looking at the former group, it seems to use a similar structure, and the actual structure comparison chart is as follows:
Although roughly similar in structure, Batis85's structure is more complex (mainly requiring extra mirrors for anti-shake), while using more special lenses, complementing its relatively high positioning and selling prices. In contrast, the FE 85 1.8 is more like a "Planar public mirror," which is slightly shabby. What about the actual quality? Look at the specific test.
Body Sony A7R2 body firmware version ver3.30
Output format RAW (uncompressed) to TIFF 8bit (uncompressed)
Tripod Manfrotto heavy tripod + triaxial gear head
ACR version ver9.8 sharpening and noise reduction All OFF
When reading the resolution data of a certain position, the lens is focused at the corresponding position to eliminate the deviation of the reading due to the field curvature of some lenses. All tests in this section are MTF50 resolution (cutoff spatial frequency at 50% reduction) in units of LW/PH (line width per plot height).
Note: Almost two years ago we did a review of the Batis 85 1.8 lens, but at the time the evaluation project was just getting started and many things were being explored without standardization (such as when the output image was not sharpened or corrected). There will be some deviation from the scores that come out. If the data of two Batis85 tests is inconsistent, this test shall prevail.
5% from the center of the image field - the center quality
FE85 1.8 can be said to be very beautiful when it comes to the performance - the full-thickness of the center under the aperture even slightly better than its expensive 4000 Batis 85 1.8, the other aperture under the picture quality is basically flat. To achieve this level of quality on the premise that the special lens is used relatively little is still quite worthy of joy.
For a portrait lens, the quality performance of the 35% (secondary center) of the center of the image field is the quality that needs to be examined. The performance of the two is basically the same (3.5% lead at the full aperture of the FE85. To be honest, this is not true The average person who sees the eye of a dog's eye can see the level).
At this point, the leading edge of FE85 has increased (8.6%), which is almost the same as the level of AB's comparison to see 100% of screenshots. However, this time is limited, only laboratory tests have been done, and there is no actual comparison chart for reference. Please forgive me.
The poor quality of the ZEISS Basis85 was considered to be a trough before, and the FE85 can also win in this respect. However, compared to the edge resolution score of the Sigma 85ART at f/2 of 2000+, it is still a little bit far off - People are not doing as big as they are. There is also a certain gap between the edge quality of the home 85/1.4GM@f/2.
Divided into chromatic aberration of magnification (intra-focus dispersion) and axial chromatic aberration (focus outside the dispersion) in two parts. The maximum value of full-frame dispersion under each focal length is measured as its actual width on the image focal plane (sensor plane).
Dispersion Control Regardless of whether it is coke or out of focus, Batis85 with a number of special lens blessings is still stronger than FE 85 1.8 with “frigidityâ€.
In terms of vignetting, FE 85 1.8 performed better than Batis85.
Distortion can be said to be Batis 85's eternal scar. The pincushion distortion is basically unforgettable to those who have used it. The FE 85 1.8 was significantly better in this respect, with 0.37% being almost vertical.
Here, in fact, Zeiss's coating is still a bit more powerful, more than a few lenses, the amount of light can win. In the beginning of the comparison chart, we can also intuitively see the differences in the extinction effect of the pre-lens coating.
The out-of-focus performance of both the overall and the spot features is not much different. After all, the lens structure is very similar.
Overall, the FE 85 1.8 is slightly slower, but it does not affect use.
Sony (SONY) full-frame mid-range telephoto lens FE 85mm F1.8 black 4299 yuan Jingdong direct link The civilian version of Batis85 - after testing, I said that I can give FE 85 1.8 such a rating. The price of nearly 3,500 yuan is cheaper than ZEISS Batis 85, and the quality of even slightly better wins (slightly better than the resolution, dispersion or worse) makes Zeiss Batis85 into an "anti-shake value of 500, the screen value of 500, small The 2500" blue mark exists. The new national bank still needs about 7,200 yuan. Obviously, unless you are using a Sony-based non-anti-body camera for the first time, and the anti-shake function is just for you, you should choose FE 85 1.8 instead of Batis85.
And when compared horizontally, the price of this lens is almost 150% of the Canon Nikon 85 1.8 specification lens, but it is not an exaggeration (in contrast to the FE50's 250% price for Canon). Judging from the current Sony Lens pricing strategy, we can fully evaluate the "conscience" of this lens - it is just that the standard of conscience is too low. No way. For now, if Sony does not have an anti-system and does not want to transfer, it will be a painful and happy thing to have more money on the camera.
In the vertical comparison, it still can't keep up with its own FE 85 1.4GM and Shima's 85ART, and even compared to the Canon 85 1.2L II and Nikon 85 1.4G under the same aperture, nothing can be done. What's more, the above four lenses still have A bigger maximum aperture - so students with higher quality and blurring requirements still have to buy more blood or rent a higher-level portrait lens. After all, it's not that money is not spent. Yeah.
