Best Canon RF Prime Lenses – For Superb Photos

Written by

In recent years there has been massive growth in Canon’s new-generation RF lens range. These lenses are designed for Canon EOS R series mirrorless camera bodies. If you consider upgrading to the Canon RF range for your full-frame mirrorless, we will help you get the best prime lens according to your need.

In this article, we will provide a list of our recommendations for Canon prime RF lenses. First, let us discuss briefly some related concepts like what is Canon RF mount, the advantages of using prime lenses, and the different types of autofocus motors.

Canon RF mount

The RF mount was announced by Canon in September 2018. It is a mount designed for its full-frame mirrorless interchangeable-lens cameras, and for RF Mount APS-C Cameras.

RF mount is characterized by its wide 54mm diameter and short 20mm flange-back distance, which promotes the ability to design lenses that are both faster and smaller than their SLR equivalents. The RF mount has a 12-pin connection between the camera and lens, compared with 8 pins in the previous EF mount. This enables much faster communication between lens and camera.

What is an RF lens?

RF lenses feature the RF mount which is designed for Canon EOS R series mirrorless bodies. These lenses work on the full-frame EOS R series bodies like the EOS RP, EOS R, EOS R6, EOS R5, EOS R5 C, and EOS R3. They are also compatible with APS-C EOS R series bodies like the EOS R7 and EOS R10. This is often recognised by a red line on the camera body and lens.

The RF lenses feature many advantages such as:

  • Superior image quality and sharpness
  • Faster communication between the lens and the camera body
  • Powerful Image stabilizer
  • It has a lens control ring that offers customisable control over shutter speed, ISO, or exposure compensation.
  • Compact size

What is a prime lens?                                            

A prime lens is a lens with a fixed focal length (fixed angle of view) and typically comes with a maximum aperture of f/1.2-f/2.8. They’re very good for photographers who want the best optical quality and prefer a shallower depth of field in their images. Popular prime lens focal lengths are 35mm, 50mm, and 85mm.

They don’t have a zoom ring and can’t provide optically magnified views of a scene like a zoom lens does. Because a prime lens has a single focal length, you can only change your field of view by getting nearer or farther from your subject, this changes the appearance of your photo by altering your perspective.

What are the advantages of using prime lenses?

There are three advantages that make prime lenses worth the money. This lens features better image quality and improved performance.

The design of Prime lenses has a major feature that is not possible with zoom lenses. Simply, they don’t need all the extra complicated lens elements that zoom lenses do. So, prime lenses have the following advantages:

  • They’re sharper, even at their widest aperture, and they don’t have the same issues with chromatic aberrations, barrel distortion, or pin cushion effect that zoom lenses do.
  • They have a larger maximum aperture. That means more light can enter your camera, allowing you to shoot in low-light situations, and use faster shutter speeds.
  • They are more compact, have less weight, and generally cost much less as they contain much less glass compared to zoom lenses

Types of the autofocus system

The requirement of an autofocus system is quite different when you are using the camera for photography or when you are shooting a video. For normal photography situations, you need a fast and accurate focusing system, however, when shooting videos you need a smoother and silent autofocus system.

Generally, there are two different types of autofocus systems used in Canon lenses: USM (Ultrasonic motor), and STM (Stepping motor)

The STM motor allows the lens to focus smoothly and quietly. The smooth autofocus creates natural and seamless-looking footage so you get clean transitions when moving between subjects or when focusing from the foreground to the background. Additionally, the STM’s near-silent focusing, allows you to record without introducing the motor sound into your video track.

The USM is well known for its extremely fast autofocus, but it is not quite. Recently designed Nano USM combines the speed and precision of USM motors when locking focus onto a subject, with the silent actions of the STM motors.

  • Thank you for the update on the Cannon RF lens.  I have very little interest and knowledge of camera lenses and photography, but I can remember that there was a time when everybody wanted a Cannon Camera as it was popular and seemed to be the best thing ever invented in that era.

    In my opinion, when the advent of the smartphone came about I thought that the hype for the camera was a thing of the past.  I really appreciate the effort you put into shedding light on the camera and that it is still relevant today.

  • I really appreciate the time and effort you put into writing such a helpful guide about the best Canon RF prime lenses. Unfortunately, I have very little expertise in this area. As a hobby, my brother enjoys taking pictures. I know this because I watched him looking up data on it. Especially about this autofocus system. Continue writing in this vein. Definitely going to forward this article to him.
