Canon launched a new RF 85mm F1.2 L USM lens, which is suitable for its own full-frame mirrorless lenses
There is such a SLR lens, almost every photographer has heard its name, this is Canon EF 85mm f/1.2L II USM, commonly known as “big eyes”, golden focal length, super large aperture plus Autofocus makes it a portrait equipment that many players dream of. In May of this year, Canon launched a new RF 85mm F1.2 L USM lens, which is suitable for its own full-frame mirrorless lenses. So what kind of performance will the new generation of “big eyes” bring? Today I will bring you a detailed evaluation.
Canon RF 85mm F1.2 L USM lens evaluation
01 Full-frame portrait new mirror king
Readers familiar with SLRs know that the original F1.2 aperture autofocus lens has always been Canon’s proud advantage One. In the era of full-frame micro-single, Canon once again demonstrated its deep technical accumulation in the field of optical design with the two super-large aperture monsters, RF 50mm F1.2 L USM and RF 85mm F1.2 L USM.
The new RF 85mm F1.2 L USM is a newly designed “Big Eye” The overall specifications of the Canon RF 85mm F1.2 L USM lens are very high
Anyway, this time we review The RF 85mm F1.2 is not a “change” of the original SLR head, but uses a brand-new structure and lens materials. It is not difficult to find from the parameter list that its overall configuration is very sincere. With Canon EOS R body, this lens can bring excellent performance in real shooting, and there are almost no defects in imaging. Therefore, the author gave it a comprehensive score of 9.3 points, which is currently the highest score we have scored.
Canon The overall score of the RF 85mm F1.2 L USM lens
Of course, the quality of the lens itself has always been proportional to its size and price. This is particularly obvious in the full image field. The maximum aperture of the RF 85mm F1.2 L USM lens It reaches 103.2mm and weighs more than 1 kg. The official price is 17,699 yuan. Obviously, this is a top-level lens for high-end players. The first part of the evaluation, then let’s take a look at the mystery of its exterior design–
02 Excellent workmanship and reasonable control
When I got this lens, the first reaction was ” “Large”, with Canon EOS R full-frame mirrorless camera looks very powerful, and the weight of about 1195 grams makes it an ideal “fitness equipment” for photographers. The lens body is coated with matte black matte material, which has good anti-skid and anti-fouling effects. Coupled with a reasonable front and rear center of gravity configuration, the actual grip of the shooting is still very good, not as difficult as it looks.
Canon RF 85mm F1.2 L USM lensThe size of this lens is really not small, and it looks very mighty when matched with the Canon EOS R body and the lens hood.
You can see the details of the lens body. This RF 85mm F1.2 L USM has a simple style. The overall workmanship is solid and meticulous. The lens body only provides a focus ring and an operation ring. The focus ring is a smooth design, and the operation ring is a step-by-step damping design to facilitate our precision. Setting parameters. The function of the operating ring allows customization, which is also a major feature of Canon RF lenses, which meets the needs of professional players for efficient control.
The lens body is equipped with a focus ring and a control ring, and the feel is very good. The control ring can be customized.The lens body provides two levers for AF/MF switching and focus range selection
For operating the levers, The lens provides two levers for AF/MF switching and focus range selection. It supports selection between the full range, 1.5 meters to infinity and two gears. It is a very practical function for portrait shooting and can be further improved Focus efficiency.
The lens coating is green and yellow. The lens adopts an internal focus design, which brings better airtightness.For high-end lenses, a metal bayonet is definitely a standard configuration
front lens group , The filter size of this lens is 82mm, with Canon ASC coating. At the same time, BR optics, UD lenses, ground aspherical lenses and other configurations are also used, which brings excellent imaging quality. The actual shooting performance of the author will be tested in detail later. It is worth mentioning that this lens uses an internal focus design, and the entire front lens group is completely sealed, which further enhances the protection and durability of the lens itself.
lens With the effect of the lens hood, it is recommended that outdoor shooting players bring
. As for accessories, the Canon RF 85mm F1.2 L USM lens is equipped with a lens hood of model ET-89. The size is also not small, almost as long as the lens body. It blocks unnecessary incident light and reduces glare and ghosting from the source. It is especially recommended to carry it when shooting outside. In general, this lens has excellent workmanship and reasonable detail design. Let’s take a look at its image quality performance.
03 is fully open and has high resolution
It should be noted that the tests in this article are all based on Canon EOS R body and directly exported from RAW format pictures, cancel All the in-camera and post-correction settings are restored to maximize the true imaging level of this lens. Let’s look at the picture quality first. As usual, the author adopts the dual test method of “resolution target reading + real shot screenshot”——
Resolution test results, the sharpness performance of this lens is quite good
EOS R highest output picture The size is 6720 * 4480, so theoretically the limit value of its horizontal resolution reading is 3360. From the data results, the Canon RF 85mm F1.2 L USM lens has a very high resolution when F1.2 is fully opened, with a center reading of 3300; after shrinking the aperture, it can run 3360 lines from F1.4 to F11. , Even the smallest aperture of F16 can reach 3200 lines.
Real shot sharpness test, we select the center and edge areas shown in the figure to zoom in and view
and then look at the actual shot sharpness test. In order to better show the resolution of the lens in the center and edge areas, the author first took a step-by-step aperture shot of the building with the same focal plane in the distance, and took a look at the sharpness of the real shot after zooming in——
Under various apertures, the center and edge image quality of this lens are impeccable
It can be seen that this lens can bring a clear imaging effect of the whole picture under the aperture of F1.2 to F16. There are rich details in the center or the edge area. Based on the results of the double test, the lens has a sufficiently high usability at all apertures, and the sharpness is very impressive.
F1.2 full-open portrait sample, the author selects the red frame area in the figure to enlarge itYou can see that this lens still has amazing resolution even when the aperture is fully open
of course As an 85mm lens, its resolution in portraits is also worthy of attention. Judging from the real shots above and the magnification effect, this lens can still bring extremely sharp details even when F1.2 is fully opened. After magnification, the model’s eyes and the hair at the focal point are very clear. , Users can rest assured to use the maximum aperture for shooting.
04 excellent dispersion and glare suppression
, let’s look at other optical performances. The first is chromatic dispersion. The RF 85mm F1.2 L USM lens is equipped with Canon’s BR lens. It has a good ability to suppress the chromatic aberration that is prone to occur at large apertures. This is also Canon’s first after the EF 35mm F1.4L II USM. Two lenses with BR technology. Let’s take a look at its dispersion suppression ability–
Even at F1.2 large aperture, this lens still has no purple fringing problem
Frankly speaking, the author has tested various high Specified lens products, but in terms of dispersion, Canon’s RF 85mm F1.2 L USM still surprised me: when the aperture is fully opened, there is no purple fringing or green fringing in the high contrast area with strong contrast. This is the first time I have seen the author with complete dispersion suppression. As an F1.2 super-large aperture lens, it is not easy to achieve this, and I must give it a praise.
In addition to dispersion, flare is also a headache for many photographers. Many lenses “see the light and die” at small apertures because ghosts produced by lens flare will interfere with the picture and affect imaging. Aiming at the glare suppression ability of this lens, the author adopted a very violent test method: directly use a point light source to directly enter the lens at a close horizontal position to simulate a strong outdoor backlight environment. So, what is the result?

In the face of flare ghosts, the Canon RF 85mm F1.2 L USM lens also has excellent suppression capabilities.Under the minimum aperture of F16, only light spots appear around the light source, and other screens There is no ghosting problem in some parts
, it can be seen that this lens also brings excellent performance in terms of flare suppression. The slight flare under commonly used large apertures is basically negligible; when small apertures only appear around the light source There are no extra ghosts in other parts of the screen. In general, thanks to the excellent coating technology, lens material and structural design, the lens has excellent suppression of chromatic dispersion and glare, allowing users to shoot backlit as they want.
Even in a small space, the blur effect of a large aperture is still very amazingUnder F1.2 aperture, the spot is round and there is no obvious “onion ring” in the spot
focus Externally, as a medium-focus lens with an F1.2 aperture, its blurring ability needless to say, we mainly look at the performance of the out-of-focus spot. From the test chart above, the out-of-focus spot of the new lens is still very round, and there is no obvious “onion ring” problem in the spot, which shows that the lens grinding level is very high.
Vignette display, you can see that there is basically no vignetting at F1.8
Furthermore, it is the performance of vignetting and distortion. The problem of vignetting of common lenses at large apertures is difficult to avoid. From the test GIF diagram above, this lens only has slight vignetting at F1.2 and F1.4, and at F1.8. Has basically disappeared, this kind of vignetting suppression ability is also superior.

It can be seen that the lens has been achieved horizontally and vertically
. In terms of distortion, 85mm is used as the middle focal length, and pincushion distortion is usually prone to occur. However, from the actual test results, this lens is basically horizontal and vertical, and it also has an excellent level of distortion suppression. On the whole, Canon’s RF 85mm F1.2 L USM lens has a comprehensive and excellent optical quality, and has a very good suppression ability in the face of common dispersion, glare, vignetting, and distortion.
05 Essentials for high-end portrait photography
Up to this point, the author’s evaluation of the Canon RF 85mm F1.2 L USM lens is basically over. I have to say that Canon’s new era “big eyes” is a very excellent lens: sharpness that can be used at full open, comprehensive optical quality without blind spots, excellent body workmanship, and even huge lens volume and weight ……Its excellent performance in the actual test left a very deep impression on the author.
Canon RF 85mm F1.2 L USM lens portrait proofs
As an 85mm focal length lens, it’s obvious that portrait photography is its power field. In the middle focal length and F1.2 large aperture, the blur ability is definitely first-class, but in addition, this lens also has bright and natural color style, soft and natural out-of-focus effect, and has enough in capturing Fast focusing speed. The excellent lens quality and the excellent performance of the Canon EOS R body have brought the author a comfortable and efficient portrait shooting experience.
Canon RF 85mm F1.2 L USM lens other proofs
Indeed, RF 85mm F1.2 L USM is a very ideal portrait lens , But this does not mean that it can only be used for portrait photography. In fact, the excellent lens quality coupled with decisive focus can bring excellent results in still life close-ups and even animal captures. This is also an unexpected gain in this review.
There is no doubt that Canon RF 85mm F1.2 L USM is a top-level portrait lens
If you want to give this lens a comment, I think it can be described as “extreme”. Canon’s goal is actually very simple, that is, at all costs, to make a large aperture portrait lens that can reach the top level in all aspects, so this RF 85mm F1.2 L USM. Although the huge size and dumbbell-like weight make people spit out several times, but in the face of excellent imaging performance, you will find that it is all worthwhile. This is the lens for high-end portrait photography.
