The Canon R5 camera is known to have aperture problems. It is because the manufacturer has assigned the aperture and shutter speed control dials to the main dial and back-of-camera dial, respectively. It means the camera will sometimes display an ‘L’ message when you use other controls, such as the shutter button.

The Canon EOS R5 and R6 feature in-body image stabilization, which other manufacturers have included for some time. The Canon cameras’ 5-axis IBIS provides up to eight stops of shake correction and a larger image circle. If your EF lens is not working properly, you can use your Canon R5 to fix the problem.
Canon R5 cameras have a wide range of EF lenses. Many of these lenses are compatible with the Canon EOS R bodies. But if you are using an older EF lens, there are a few problems you should be aware of. One of them is that the AF Stop button does not function correctly. Another problem is that the Canon EF 35-80mm f/4-5.6 PZ lens cannot use the power zoom function. Fortunately, all other EF lenses will work properly on the Canon EOS R.
Autofocus system not infallible
If you are using a Canon EOS R5 camera, you may have noticed that the aperture is not functioning properly. To fix this problem, you can adjust the settings in the camera’s menu or take it to a repair shop. The most common cause of these issues is the lens.
The aperture on the Canon EOS R5 is fixed by adjusting the lens’s maximum aperture. The maximum aperture can be up to f/22. It is a great improvement over the previous models. In the past, the autofocus system on the Canon EOS 6D would not focus lenses with a maximum aperture greater than f/5.6. On the Canon EOS 5D Mark IV, the autofocus system would tap out at f/8; the R5’s autofocus system can focus lenses with a maximum aperture up to f/22.
While the EOS R5 is primarily a stills camera, the lens has excellent low-light performance. The camera can focus on landscapes with low-light levels up to -6EV. It is equivalent to the light available at night under a full moon. It also offers 8K video. Despite these features, the Canon EOS R5 has a few limitations and can’t be considered a perfect camera.
RF lenses are not working properly.
Many users report problems with their Canon R5 camera’s aperture, which may be due to the failure of their RF lenses. RF lenses are designed for video and cinematography and have more advanced features and capabilities. These lenses have more apertures and are designed to be smaller in size. It means that the R5 can take advantage of larger apertures while still reducing light fall-off. RF lenses are supposed to be lighter than EF lenses, which is a good thing for photography but can pose a video problem. The weight of a lens is important for video and provides stability when moving the camera. Lightweight lenses also put less stress on human arms and motors.
If your R5 is experiencing aperture problems because of the RF lenses, you may be able to fix the problem by using an alternative lens. If this is not an option, you can try using another lens, such as a Canon RF 24-240mm f/4-6.3 IS USM. This lens has five stops of Image stabilization, which can be toggled on or off.
Control ring sticking
If your Canon R5 is having problems with the aperture mechanism, you may notice that the Control Ring is stuck and is not moving when you attempt to open the aperture. It can be caused by excessive oil on the blades or other problems. When this occurs, you should replace the Control Ring.
Aperture problems are also common problems with Canon R5 cameras. These cameras default assign shutter speed and aperture control to the back of the dial. While this can make adjusting the aperture difficult, a firmware update will solve this problem. If this does not work, either you can read your Canon camera Manual, or you may need to take your camera to a service centre to fix it.
Another common cause of sticky aperture blades is physical damage to the aperture mechanism. It can include bent blades, damaged aperture linkage, or broken aperture control levers. Sometimes, the control ring can be bent by accidentally handling the lens or a sudden shock. It can cause the aperture lever to break or damage the camera’s electrical contacts.
Canon R5 camera users should know about the camera’s battery life and aperture problems. The camera may fail to adjust its shutter speed or ISO low enough to get the best shot. It results in under-exposed images. The camera’s firmware needs to be updated to solve this problem.
Using an external battery charger is not the best idea for the Canon R5. The batteries used by this camera are smaller than the ones supplied by Canon. Also, the burst speed is much slower when the battery level is under 60%. It is not a big deal for casual shooters, though. A second option is to purchase two batteries from Canon and use one for the camera.
Canon R5 users should also be aware that the camera’s battery life is not the best, but the camera still provides good image quality. The camera features a good IBIS system, which rivals four-thirds of cameras. The IBIS can give up to eight stops of compensation, which is good enough for handheld shooting.
