The lightest big three yuan Canon RF70-200mm F2.8 review

   Today we are going to test Canon’s RF70-200mm F2.8 L IS USM, which is a lightweight telephoto ternary with excellent performance. For 70-200mm, this lens is currently the lightest of all 70-200mm f/2.8 lenses. What is the quality of this lens? Let’s take a look at today’s test.

01 Overview

  After the release of Canon RF70-200mm F2.8, all three major three elements of the Canon RF mount have been assembled. This lens is different from all previous 70-200mm. It uses an external zoom design, so the volume and weight have been greatly reduced. The length is only 146mm, and the weight is only 1070g. This kind of volume and weight is more coordinated when used with mirrorless cameras.

   Although this lens is small in size, the image quality is very good . No matter it is from the center to the edge, the image quality of the lens is satisfactory. For out-of-focus imaging, the new lens uses a 9-blade aperture, which makes out-of-focus imaging quite good. As for the focusing speed of the lens, the focusing speed of the lens is very fast, but due to the difference between the mirrorless single-lens and the SLR, the speed advantage of the lens is not reflected.

   For this lens, I gave a high score of 8.9 , Because this lens achieves good volume and weight control while ensuring high image quality.

02 lens design

   For this lens, the most worth mentioning is the volume and weight control of the lens. Compared with the previous generation lens, the lens is not only shortened by 53mm in the stowed state, but also reduced by 410g in weight. This kind of “weight loss” is very successful. It can be said to be very lightweight when paired with EOS R, RF70-200mm F2.8 and the body weight does not exceed 2kg.

   The three lenses from left to right are: RF70-200mm F2.8 L IS USM, EF 70-200mm f/2.8L IS III USM, EF 70-200mm f/4L IS II USM. It can be seen from the volume that the new lens looks thicker, but the length is the shortest. However, the new lens is an external zoom design, which means that the lens will extend when zooming. We can look at the length after extending.

   Actually, after the RF70-200mm F2.8 lens is extended , The length at the 200mm end is longer than the other two lenses. The external zoom design actually tests the protection of the lens even more, but Canon’s lens sealing design is still quite good, and there is basically no need to worry about dust in the use.

   The hood of the new lens is also white, but this generation uses With a cylindrical hood, instead of a lotus-shaped hood, it looks less aggressive. However, the new hood has a filter window. When using CPL, you can also adjust the filter angle with the hood.

   Different from the previous lens, this lens has an obvious feature. Is the aperture front. The aperture position of the lens is very forward, which is a very commonly used design method in modern lens design, generally in order to obtain better picture quality while reducing the volume. The lens itself is a 9-blade aperture design, so it has a more rounded spot and better out-of-focus imaging.

   The lens coating is still mainly yellow-green coating, the new lens The coating is quite ideal, which can effectively suppress glare and ghosting when shooting against the light. In addition, the caliber of RF70-200mm F2.8 is also 77mm.

  The lens has four switch levers, namely: focus range Shift lever, focus mode lever, anti-shake switch, anti-shake mode lever. These are the four switch levers commonly used in 70-200mm lenses. This lens is not equipped with the currently popular focus preset button.

   In the lens design, the lens is from top to bottom, the widest is the zoom ring, the middle part is the focus ring, and the custom multifunction ring is located at the lens foot The rear part of the frame ring. From the point of view of use, the position of the three lens rings is reasonable, but the width of the manual focus ring is a bit small, and it will be more convenient if it is larger. The custom multifunction ring is at the end, so you need to pay attention when adjusting.

  The lens tripod ring is a detachable design, but unlike the previous generation, the new lens tripod can be directly disassembled, which means that we can directly remove the tripod without removing the lens from the camera Ring up.

   Let’s take a look at the key content below, which is the image quality test of this lens.

03 Optical Performance Test

   Many friends care about this lens and the EF 70- 200mm f/2.8L IS III USM, which is the little white umbrella who has better picture quality. Here we also compare the two lenses. The picture here is relatively long, I hope you can watch it patiently.

   At the 70mm end, the image quality of the two lenses is basically the same. The sharpness of the center of the two lenses is basically the same, while in terms of edge performance, the EF’s 70-200mm image quality is slightly better than the RF lens.

   At the 200mm end, the center sharpness of the new lens is not as good as the old lens when the aperture is fully opened, but the edge sharpness is much better than the old lens. In general, the image quality of the two lenses is the first echelon of the current 70-200mm f/2.8. However, considering all things considered, the author believes that the image quality of the RF mount lens is better than that of the EF lens.

   Next, we will focus on the image quality of the new lens. The first is the dispersion performance of the lens. When the new lens is fully opened at the 70mm end, there is almost no visible dispersion.

   But at the 200mm end, it can be seen more clearly when fully opened The dispersion. The dispersion basically disappears when it shrinks to F5.6. To be honest, the dispersion performance of the RF lens is not particularly ideal at medium and telephoto. Correction is needed to remove the influence of dispersion.

  For 70-200mm lens, the glare when shooting with backlight And ghosting is more serious than regular focal length. The backlight performance of this lens is relatively good, you can see the appearance of some ghosts, but relatively speaking, the backlight performance of this lens is acceptable.

   The vignetting performance of this lens is very good, no matter it is 200mm , Still 70mm, the vignetting when fully opened is not serious. So when shooting with this lens, you don’t have to worry about vignetting.

   As for distortion, 70-200mm itself is a focal length with certain distortion, so slight distortion is not unexpected. From the actual performance, a certain barrel distortion can be seen at the 70mm end, but it is not serious. There is a slight pincushion distortion at the 200mm end, and the deformation is very small.

   The last item is a very important test for this lens, which is the out-of-focus performance. 70-200mm is often used as a portrait lens, so the out-of-focus performance is very worthy of attention. The out-of-focus light plate of the new lens is very round, and the out-of-focus image is quite good.

The lightest big three yuan Canon RF70-200mm F2.8 review

   We can see the bokeh effect of the lens in the following photo , Here we first look at the out-of-focus imaging of the progressive aperture.

  RF70-200mm F2.8 This lens has another advantage, that is, the closest focusing distance is 0.7m, which makes it more convenient to shoot at close range, when shooting still life , We don’t have to exit to go far to shoot.

04 Anti-shake and focus

   Another point, the lens itself has optical anti-shake. In actual use, we use 200mm for shooting, and the minimum shutter speed of 1/15s can be used for handheld Shooting, this kind of anti-shake effect is quite powerful.

The lightest big three yuan Canon RF70-200mm F2.8 reviewThe lightest big three yuan Canon RF70-200mm F2.8 review

   For the focusing speed of the lens, if you use single focus, the focus of this lens is very fast. We use the EOS R body and use the new RF Compared with the latest EF 70-200mm f/2.8, the focus speed of the new lens is even slightly better than that of the old lens.

The lightest big three yuan Canon RF70-200mm F2.8 review

   But in terms of dynamic tracking performance, it is restricted by EOS R machine Due to physical limitations, if the new lens works with the eyes to focus in the environment of the shooting task, the focusing speed is very sensitive. But if no people appear, the dynamic focus performance will be limited because the EOS R body’s ability to capture dynamic objects is weak.

   However, as long as the body can successfully identify and track the subject, the new RF lens can still achieve excellent focus tracking performance.

05 Summary and Samples

   Finally, let’s talk about the experience of using this lens. The biggest feature of the new lens is its lightness. With EOS R, we can get an unprecedented lightweight shooting experience. The body and lens weigh less than 2kg, which was just a little more than a lens before.

   The image quality of the lens is satisfactory, no matter it is Fully open, or reduce the aperture. This is a large-aperture telephoto lens with excellent image quality. It can not only be used for portrait shooting, scenery or still life, but also excellent. And the closest focusing distance of the new lens has been increased to 0.7m, making shooting more convenient.

  The new lens has excellent focusing and anti-shake performance, and the out-of-focus imaging is very good. It is a very good 70-200mm large ternary lens. But the lens also has some shortcomings. The dispersion performance of the lens is not perfect. In addition, some flare and ghosting may appear when backlighting.

  In general, this lens is still the best 70-200mm lens. Let’s take a look at more real samples.
