   The 85mm focal length lens has excellent spatial compression and soft and soft out-of-focus effects, which can make the subject appear more three-dimensional and beautiful. It has always been a classic of portrait lenses. Focal length. The small and light lens is the first choice for street-sweep shooting. Even if 85mm and 135mm are portable, they can also be used for street-sweeping shooting. For example, the EF 85mm f/1.8 USM lens has been favored by movie friends for more than 20 years since its launch, because it is not only a classic portrait focal length, but also compact and lightweight, suitable for street shooting.

The EF 85mm f/1.8 USM lens has been favored by movie friends for more than 20 years since its launch

  Of course the EF 85mm f/1.8 lens has been out for many years after all Everyone is also looking forward to seeing an RF lens with a large aperture and a lightweight 85mm focal length in the new era of mirrorless cameras, so in 2020 Canon launched the RF85mm F2 MACRO IS STM lens. Judging from the published parameters, this lens is compact and light. , With F2’s large aperture and soft out-of-focus blur performance, it also comes with a macro shooting function. What is the real shooting experience of this lens, let us reveal it for you in the next review.

  Appearance

   At first glance, the appearance of the RF85mm F2 MACRO IS STM lens does not seem to be very eye-catching. There is no red circle on the lens body, and there is no “big eyes” like most 85mm fixed focus. “However, as the saying goes, although the sparrow is small and complete, this small mirror body not only houses an anti-shake mechanism that can be linked to the body, but also has a maximum magnification of 0.5 times, and the nearest 0.35 meters Focusing distance shooting macro, and the characteristics of the large aperture and short rear focus distance of the RF mount also provide a reliable guarantee for the image quality of this lens.

  RF85mm F2 MACRO IS STM

   Although the large aperture and high image quality are really attractive , But such lenses are often too bulky, and what everyone just needs is a small and light lens. Of course, it would be better to have a large aperture and high image quality on this basis. Like the previous RF 35mm F1.8, the RF85mm F2 lens has also achieved an excellent balance between volume and high image quality with a large aperture.

   This lens is not only in appearance Miniaturized and light enough in weight. The weight of about 500 grams is only over 900 grams with the smallest micro EOS RP. The overall appearance is very harmonious, and the combination with the flagship EOS R5 is only more than 1,200 grams. Matching with the camera body is not top-heavy, and will not be “aggressive”, which is more conducive to street sweeping shooting.

   This lens uses the design of the control ring in the front and the focus ring in the back. The silver metal ring near the front of the lens is the control ring. The surface of the control ring uses a diamond-shaped non-slip different from the focus ring. The design provides a good feel, and it is also convenient for users to operate blindly. Behind the control ring is the focus ring, anti-shake switch, focus selection switch, AF/MF switch, and the overall controllability is good.

   The last thing worth mentioning is that although this Only the lens is designed for external focus, but in fact, it does not change the length of the lens body when focusing in non-macro shooting state, and the front of the lens will be extended when focusing in macro shooting. I personally feel that this design is not The problem, after all, practicality comes first.

  distortion and vignetting performance

  The design of the lens is a complicated project. In order to achieve a balance or strengths between various performances, there must be compromises on other parameters , Especially for small and lightweight lenses, there are often compromises in other performance. However, with the advent of the digital age, this problem has been better solved. Features such as distortion and vignetting can be easily solved by in-camera correction and post-adjustment, making it easier to “hard indicators” such as resolution and dispersion. In order to better understand the characteristics of the lens, we still have to take a look at the distortion and vignetting performance of this lens.

   First look at the distortion performance. Distortion is divided into barrel and pincushion. It is most obvious when shooting some line objects. Relatively speaking, wide-angle lenses are more prone to distortions that are difficult to correct, while medium-telephoto lenses It’s much easier to control. We turn off the correction function of the camera body to shoot. You can see that the Canon RF85mm F2 MACRO IS STM lens has only a slight pincushion distortion. If it is not for the comparison of auxiliary lines, it is basically impossible to detect. Distortion, after opening the body for correction, the distortion disappears completely.

   vignetting is also called loss of light, Simply put, it is caused by the insufficient amount of light through the lens and the large angle between the incident light from the corner of the lens and the optical axis of the lens, and the amount of light through is directly related to the aperture of the lens. It is the same as distortion, which can be easily passed through later. The lens characteristics solved, usually wide-angle lenses are prone to vignetting at large apertures. Next, let us take a look at the performance of this lens in terms of vignetting.

  Turn off the in-camera correction and shoot at F2.8

   During the test, we turned off the vignetting correction function in the fuselage. You can see that the Canon RF85mm F2 MACRO IS STM lens only works at the maximum aperture of F2. There is a very slight vignetting, when the aperture is reduced to F2.8, the vignetting disappears completely. It can be said that the body correction can completely eliminate the vignetting, and even if the camera is turned off to correct the slight vignetting, it will not affect the normal Shooting, if you like to add a small amount of vignetting as a photo expression, you can safely turn off the in-camera correction.

  resolution performance

   Canon RF85mm F2 MACRO IS STM as a classic portrait focal length lens, its optical performance is definitely one of the focuses of people’s attention. It is equipped with an optical structure of 12 elements in 11 groups, and a large-diameter lens is placed closer to the imaging surface, which gives full play to the advantages of the large-diameter and short rear focus distance of the RF bayonet, and enables high image quality and optical structure around the screen. The miniaturization becomes possible.

   In order to ensure that the samples are as objective as possible, we turn off various optimizations. When shooting, the camera is fixed on a tripod, and the internal white balance is set to automatically shoot the aperture step by step, and the positions shown by the red frames at the center and edges are intercepted 100% magnified slices of, the results are as follows:

   can see, The sharpness performance of the Canon RF85mm F2 MACRO IS STM lens center image quality at the maximum aperture is satisfactory, reaching the standard for the maximum aperture, and the aperture is reduced to F2.8 for the best sharpness performance, and From F2.8 to F11, the image quality has been maintained at this level, and the image quality is attenuated at F16. In the case of a smaller aperture, the relative image quality is greatly reduced due to the effect of diffraction. From the perspective of the image quality performance of the edge, although the image quality at the maximum aperture is not as sharp as the center, it does not open a large gap, and the usability is quite high. It also maintains the best between F2.8 and F11 The image quality has deteriorated due to diffraction at a smaller aperture.

   and From the 100% magnified screenshots of the actual samples taken by the author, we can see that the hair details of the cat’s eyes and the details of the pupil and iris are clearly visible. If you observe carefully, you can even see the author’s figure reflected on the cat’s eyes. Such a resolution can fully meet the needs of portrait shooting, and it can also bring better details for street sweeping shooting.

  Out-of-focus and dispersion performance

   In addition to the resolution performance, the lens’ anti-dispersion ability, which is the suppression of the “purple fringing”, is also a very important quality. In the face of backlighting and high-contrast shooting, the influence of chromatic dispersion on the picture cannot be ignored. The RF85mm F2 uses a UD lens that can effectively suppress aberrations, thereby effectively reducing the axial chromatic aberration that may appear before and after the focal plane. Next, we also use real shots to understand the anti-dispersion performance of this lens:

   It can be seen that this lens has a very good dispersion suppression performance. For the highlights of metal objects, there is no obvious “purple edge” or “green edge”. It should be said that such performance is satisfactory. Of course, for a lens with a macro shooting function, the depth of field is usually relatively shallow due to the scene of use. In addition to the in-focus chromatic aberration, the out-of-focus chromatic aberration is also very important, so let’s take a look at this lens. Axial chromatic aberration.

   We conducted a macro test shot of bird model toys. By observing the magnified slices of the sample, it is found that this lens still has a small amount of dispersion at the maximum aperture, but for such a large aperture macro lens, this slight dispersion is expected, and we can use it. After shooting in RAW format, there is no obvious dispersion when the aperture is reduced to F 2.8, so this dispersion suppression performance is still very good.

   Considering that the Canon RF85mm F2 lens is actually shooting In medium, both portrait shooting and night scene sweeping will use large aperture shooting, so its out-of-focus performance is also what we need to pay attention to.

   performance outside the RF85mm F2 focus It can be seen from the aspect that when the aperture is fully opened, the circular aperture formed by 9 aperture blades forms a rounded out-of-focus spot shape, and there is no “onion ring”. The sharpness of the subject in the focus is very high and the background blur is excessive. It is more natural and gives people a soft feeling. This kind of performance can provide a very beautiful out-of-focus blur effect when shooting night scenes, while the edge of the picture spot appears slightly eroded, but if you look at the size and pricing of this lens , This kind of performance is acceptable, and it is absolutely superior in the same specification lens.

  Anti-shake performance

  Whether it is in situations where the camera cannot be kept stable or a tripod cannot be used, or when shooting still life, night scenes, etc., you want to lower the ISO sensitivity to get more noise When there are few high-quality images, anti-shake will largely determine our filming rate. The optical anti-shake of the RF85mm F2 lens has a 5-level hand-shake compensation effect. Let’s take a look at this. For the anti-shake performance of the lens only, we select the shutter priority exposure mode, turn on the lens anti-shake, start from 1/250s, the whole file is lowered for handheld shooting, and the zoomed slice of the screenshot is as follows:

   During the whole test, the author used the hand-held camera to shoot. It can be clearly seen from the screenshot that it was taken from 1/250s to 1/ Within 15s, the focus is relatively clear, but as the shutter speed slows down further, there will be traces of jitter at the focus, but a clearer image can still be obtained. Afterwards, a slower shutter speed can hardly ensure the stability of the picture, but this The anti-shake performance is already very good for medium and long-range fixed focus lenses, and it is of substantial help for us to use lower sensitivity to shoot with higher image quality.

   And from the author’s actual shooting experience, This lens gives the author a brand new choice for sweeping the street. The 85mm focal length of about 28 degrees can easily strip the subject from the background in street photography creation, making the creation more comfortable, and at the maximum aperture of F2 Under the circumstances, this lens has very good detail expression. After the aperture is properly reduced, not only does it not affect the soft focus texture of the background blur, but also gives the subject a better resolution performance, which is very suitable for street sweeping creation.

   In addition, the 85mm focal length allows us to maintain the subject Appropriate shooting distance is also very suitable for taking photos of pets. When used with EOS R5/R6 with animal detection autofocus, the camera can only recognize and track the face and eyes of animals, allowing us to capture them inadvertently The timing of the shutter will not miss their cute moments because they are too late to focus.

   Of course, RF85mm F2 MACRO IS STM is a classic The large-aperture fixed-focus lens with portrait focal length can maintain a moderate distance from the subject when shooting portraits, and communicate with the model more naturally. When shooting, there will be no facial distortion caused by the perspective effect of a wide-angle lens, nor will it bring obvious compression effects like a telephoto lens. The appropriate three-dimensional sense of the character and the sense of perspective with the background, combined with the soft and virtual of the F2 large aperture The effect is very good to bring out the beauty of the model and obtain very beautiful portrait photos.
