Why Are Rf Lenses So Expensive? [6+ Reasons]

Photography is not only about the skill that one possesses but it is also concerned with the camera and the lens that one uses. That is why enthusiasts are always on the search for the best and latest lenses in the market. And when it comes to cameras and technology, everyone’s eyes are set on Canon, and what they are offering in their new product.

With the new RF lenses, Canon unlocks imaging for the new age. With better quality, design, and new technology, the prices soar higher and higher. This is the reason why Canon RF lenses are so expensive.

The rf lenses available in the market can range from the prices of $300 to $3000, with a wide variation in their design and quality. To find out why they are so costly and yet people purchase them, keep on reading.

Reasons Why Are Canon Rf Lenses So Expensive

1. Multilayered:

Canon rf lenses have a special multi-layer coating on the surface of the lens. The topmost part is the ultra-low refractive index layer while the bottom layer is made up of deposition lens coating. This layering is known as Air Sphere Coating (ASC), which reduces light reflection.

The RF lens Canon is coated with nanosized wedges aligned tightly together on the surface of the lens. This is known as SWC. This technology reduces reflection, minimizing flaring, and ghosting making short-back focus possible.

As you may already be aware of the fact that incorporating advanced technology into products dramatically increases their cost value.

2. 12-pin electronic connection:

The new 12-pin electronic connection boosts transmission between the lens and camera and enables large volume data transfer with higher velocity. This allows the system to operate for numerous years.

This enhanced connection enables the camera to bring about modifications adjusted to each lens and attain high accuracy image stabilization, thus developing impressive image quality.

3. Short flange focal distance:

The distance from the Mount to the image sensor is called flange focal distance. The shorter the flange focal distance, the more outstanding the image quality. This is because in a shorter flange focal distance rearmost lens elements would be much nearer to the sensor.

To achieve a much shorter flange focal distance, what canon did was remove the mirror between the lens and sensor. This eliminates the space that was, previously, occupied by the mirror, resulting in the flange focal distance is decreased.

The flange focal distance of rf lenses is 20mm which is less than half of the flange focal distance of DSLR cameras. This results in greater flexibility to adjust the lens, giving us promising image outcomes.

4. Larger mount diameter:

Usually, the outlines and detailing of background elements in the image are blurred.  To counteract the problem, it is required that the lens have a greater aperture.

Now it is generally found that a greater Mount diameter would provide a larger aperture diameter. Canon has found its perfect aperture at an internal diameter of 54 mm in the RF lenses.

A larger mount diameter also helps deliver excellent image value along with enhancing the usability of the camera.

5. Faster focusing:

With the new RF lenses, Canon delivers focusing power faster than ever before. It consists of 2 USM motors that drive 2 separate lenses, each cooperating to deliver much more efficient and faster focusing.

This operation largely benefits vloggers and wildlife photographers as they have to move around quickly and don’t have much time to wait for focusing.

6. Control ring:

Aside from the focusing ring and zoom ring, the rf lenses possess a control ring. By turning the control ring you can alter the designated exposure settings just like an aperture ring does in manual focus lenses.

You can decide when to make the ring operation and when to turn it off. To enable the functionality of the control ring, click on the camera function in the menu and select customize dials.

The control ring is a customized ring that can manage features such as shutter speed, exposure compensation, aperture, and ISO speed.

7. Lens information display:

Forgetting about the focal length of the lens is not unheard of. To tackle this, Canon displays its lens details right in the viewfinder, so that you can confirm the focal length of your lens without looking away from the display of your camera.

Is the Canon RF lens full frame?

Yes, the Canon RF lens is a full frame, ultra-wide, compact, and affordable lens for the EOS R series. It is designed especially for content creators and vloggers.

Do all rf lenses possess a weatherproof mount?

Yes, all Canon RF Mount lenses are weatherproof. They have a thin layer of rubbery plastic on the lens mount of the camera.

Do rf lenses support image stabilization?

Yes, one of the most significant features of RF lenses is that of image stabilization. Both, the camera as well as the lens work in coordination to drastically reduce blurring, whether that be in creating videos or images.

Can I use RF lenses on a DSLR?

No, you can’t use RF lenses on a DSLR. The reason for this is that it has a short back focus design which means that the distance between its rear-most lens and sensor is reduced to the maximum.

Due to this, the rf lens wouldn’t be able to attain focus as the sensor would be too far away.


Now, the reasons ‘why rf lenses are so expensive’ must be, somewhat, clear to you. Despite its high-cost value, tons of people buy the product, and the reason behind it is its highly innovative and creative technology.

Moreover, it’s effortlessly understood that with such brilliant features, the price of the product would also rise. This product is highly recommended to professional photographers and photography enthusiasts. This will increase your creativity but only at a high price.
