In the SLR era, Canon’s great white family has always been favored by photographers. The EF 100-400mm f/4.5-5.6L IS II USM released in 2014, known as the White Rabbit, is still the first choice for many users. In the era of mirrorless lenses , this lens ushered in a new form-RF100-500mm F4.5-7.1 L IS USM. This lens has a longer focal length and a lighter lens design. It can be said to be a Very versatile professional super telephoto lens.

Overview

    For the Canon RF100-500mm F4.5-7.1 L IS USM lens, first of all, this is a professional telephoto lens, suitable for a wide range of subjects, covering travel scenery, animal and bird photography, sports photography, airplanes Ultra-long-distance photography subjects such as the moon, etc.

    This lens has two major characteristics, one is that the telephoto end reaches 500mm, and it still retains a close-up focal length of 100mm. In fact, there are already many lenses that can achieve 500mm or 600mm telephoto, but the starting focal length for close-ups often needs to be 150mm or even 200mm, so Canon RF100-500mm still maintains the possibility of close-up.

    Another point, this lens weighs only 1370g, but the second-generation EF 100-400mm lens weighs 1570g. In other words, the new lens is not only 100mm longer, but also 200g lighter than the white rabbit in the SLR era.

    This lens also has the ability of macro photography. At the 100mm end, the closest focusing distance is only 0.9m, while at the 500mm end, it can achieve a magnification of 0.33 times. Therefore, this lens can capture macro subjects such as tiny objects, flowers, butterflies and insects.

    For this lens, the author gave a high score of 8.8 points. The portability and image quality of the lens are very good, but when the lens is shot against the light, it will inevitably have some glare as an ultra-telephoto lens, which is unavoidable.

Second, the appearance of the lens

    The Canon RF100-500mm F4.5-7.1 lens is a lightweight ultra-telephoto lens with a weight of 1370g, a weight of 1530g with a tripod ring, and a filter diameter of 77mm. The lens is matched with the EOS R5 body, the proportions are very coordinated, and the weight ratio is natural, so you will not feel tired when holding it for a long time. The lens itself is still a telescopic lens barrel, the 100mm end is fully retracted, the length is 207.6mm, and the 500mm is fully extended, the front end of the lens will be extended to a greater extent.

    The lens itself still uses Canon's classic white coating, which can reduce heat absorption and make it more comfortable to use when shooting. The lens has a wealth of physical buttons and adjustment rings. The wider front part of the lens is the zoom ring, and the narrower black part at the rear is the focus ring. The rear part of the lens is close to the body part and has a custom multi-function ring that Canon RF lenses have.

    As a professional telephoto lens, the lens has four physical buttons, namely the focus distance selection lever, the AF/MF switching lever, the anti-shake switch, and the anti-shake mode selection lever. It should be noted that there is a rotating ring above the physical buttons, which can adjust the intensity of the lens when zooming. If we do not need to zoom frequently, we can set it to TIGHT mode to keep the focal length unchanged; while in scenes that require frequent zooming, we can switch to SMOOTH for a smooth zoom experience.

    The lens uses a 77mm filter aperture, and the coating color is yellow-green. This lens also uses ASC coating, which not only reduces flare and ghosting, but also improves the shooting quality of the lens. However, in actual use, as an ultra-telephoto lens, the anti-glare performance of Canon RF100-500mm is weaker than that of a normal focal length lens.

    This lens is equipped with a detachable tripod ring and weighs 160g, which is very light. Compared with the EF 100-400mm lens tripod ring, this lens can be removed as a whole, which is more convenient to use.

    The lens uses a cylindrical lens hood, which also has a filter window, which is convenient for us to quickly adjust the filter angle when using CPL.

Three, resolution test

    The image quality of this lens is very satisfactory to the author. Let’s take a look at the sharpness of this lens in actual tests. The first display is the image quality performance of the 100mm end.

    This lens has excellent sharpness at the 100mm end, and it always maintains high sharpness from the center to the edge at full aperture from F4.5 to F16. The most gratifying thing here is the edge image quality of the lens. Since F4.5 is fully opened, the image quality of the edge of the lens is very good, and this sharpness has been maintained until the F22 aperture.

Let's take a look at the 500mm end image quality performance.

The resolution of the lens at the 500mm end is weaker than that at the 100mm end, but it also shows good image quality. When the lens aperture is fully opened, there is relatively good center and edge sharpness performance, and the image quality has declined since F16.

    Overall, this lens has quite good sharpness. Below we can look at a few photos to see how the camera performs in actual shooting. First of all, the first one is a photo taken when the camera's aperture at the end of 500mm is fully opened.

    We can see that at the 500mm end, when the aperture is fully opened, this lens can achieve excellent picture details with the R5's 45 million pixels. And 500mm also has great practical value in landscape photography, such as shooting magnificent landscapes such as Tibet and Xinjiang, or shooting buildings in cities from a distance. 500mm is very practical.

When shooting in the city, this lens also has excellent sharpness performance at 500mm. Therefore, the actual sharpness of this lens at the 500mm end is completely sufficient.

Fourth, the anti-shake and focus of the lens

    Although this lens is a telephoto lens, it can be used with Canon EOS R5 to obtain a very good dual anti-shake effect. After upgrading the firmware, the body + lens dual anti-shake effect can reach 6 levels, which can be achieved in official data. We also tested the 1/2s handheld effect at the 500mm end.

    This photo was taken using 500mm, the fast speed is 1/2s. In the actual shooting, the author did not use a tripod, and completely handheld shooting, you can see the enlarged picture details, although it will be blurred, but the clarity has been maintained within the usable range.

    Another major advantage of this lens is its focusing performance. This lens can maintain fast and stable focus when shooting various scenes. It is particularly worth mentioning that both Canon EOS R5 and R6 have bird eye focus. This lens is equipped with bird eye focus. When shooting birds, you can get a very stable continuous focus effect.

This lens is also very suitable for sports and sports photography. Here we use the aquarium’s ocean theater performance as an example. When shooting, the author’s sensitivity has been used to ISO 25600. In a relatively dim indoor light environment, Canon RF100-500mm F4.5-7.1 lens with EOS R6 can still perform Stable continuous shooting.

Five, optical performance

    For an ultra-telephoto lens, the optical performance of the lens is also worthy of attention. First of all, the vignetting control of this lens is quite good. At the 100mm end, when the F4.5 is fully opened, there is a relatively slight vignetting, while at the 500mm end, the vignetting is very slight.

    The distortion control of the lens is also excellent. There is basically no distortion at the 100mm end, and a certain pincushion distortion can be seen at the 500mm super telephoto end, but it can be quickly corrected in the later stage.

    The anti-glare performance of this lens is not ideal, but all ultra-telephoto lenses are not as good as normal focal length lenses in anti-glare performance. As long as this lens is not directly facing the sun, the glare control is acceptable for daily shooting.

    The dispersion performance of the lens is very good. When the aperture is fully opened, we shoot high-gloss metal edges, and almost no dispersion appears.

    The last thing worth mentioning is the out-of-focus performance of the lens. As an ultra-telephoto lens, the closest focusing distance of this lens is quite close, only 0.9m at the 100mm end, so this lens has quite good blur performance.

It is worth noting that this lens can achieve a maximum magnification of 0.33 times at the 500mm end. This lens actually has a strong macro shooting capability. Combined with ultra-telephoto, you can shoot some small insects and the like.

Six, samples and summary

    Canon RF100-500mm F4.5-7.1 L IS USM is an ultra-telephoto lens with excellent image quality and light weight. The lens has a wide range of applications, not only suitable for super telephoto subjects such as birds and sports photography, but also for landscape photography, super telephoto lenses are also very practical.

The sharpness of the lens is quite good. The 100mm end can get sharp image quality. Although the 500mm end has a slightly lower image quality than the 100mm end, it still has good detail resolution. The edge image quality of this lens is particularly noticeable. When the aperture is fully opened, it can have excellent edge image quality, and the vignetting control is also quite good.

    If there is any shortcoming of this lens, it is that when the lens is backlit, there will be a certain amount of glare. But overall, this is a very professional ultra-telephoto lens.
