7. Canon RF 50mm F1.8 STM

The Canon RF 50mm F1.8 STM is a full-frame lens that also pairs well with the Canon EOS R50.

If you’re in search of a versatile “nifty fifty” prime lens for everyday shots, portraits, and creative expression, this lens is definitely worth considering.

The autofocus is driven by an STM motor, but the lens lacks in-lens image stabilization. Therefore, you will need a steady hand or higher shutter speeds since the R50 does not feature in-body image stabilization (IBIS).

The lens offers a fixed focal length of 50mm, which is equivalent to 80mm on a full-frame sensor, and boasts a fast maximum aperture of F1.8 and a minimum aperture of F22.

The minimum focusing distance is 30cm and the maximum magnification is 0.25x.

I own this lens myself and it is a fantastic little lens for the price. I’ve not used it on the R50 but here’s a shot of our dog Frank taken with my Canon R5.

The Canon RF 50mm F1.8 STM lens is constructed from 6 elements in 5 groups and features 7 aperture blades. It has a 43mm front filter thread. The lens also includes a dual-function focus/control ring with a switch on the body for easy operation.

In terms of dimensions, the lens measures approximately 2.72 inches (69.2mm) in diameter and 1.59 inches (40.5mm) in length, and it weighs 5.6 ounces (0.35 pounds or 160 grams).

There is no lens hood included in the box so this would need to be purchased separately if required. The correct lens hood for the Canon RF 50mm F1.8 STM lens is the Canon ES-65B (B&H | Amazon).

Sample photos from this lens can be found in the Canon RF 50mm F1.8 STM Image Thread over on our forum.

10. Canon RF 24-240mm F4-6.3 IS USM

The Canon RF 24-240mm F4-6.3 IS USM is a full-frame lens with a compact design, covering a versatile focal range from 24mm to 240mm. This makes it an ideal travel lens if you’re looking for one lens that can handle a variety of situations.

With a variable aperture of F4-6.3 and optical stabilization that provides 5 stops of correction, this lens helps you achieve sharp images even at slower shutter speeds.

In terms of image quality, this lens delivers decent results throughout the zoom range, though it may not be the sharpest. However, for most users, especially those not focusing on pixel-level detail, the image quality will be satisfactory.

The lens has a minimum focusing distance of 0.5m and a maximum magnification of 0.26x, allowing for close-up shots of various subjects.

Unfortunately, the lens does not come with a hood; you will need to purchase the EW-78F lens hood separately. Using a hood is recommended as it not only reduces glare but also protects the lens from accidental damage. It’s better to damage a replaceable lens hood than the front lens element.

Additionally, this lens is not dust or moisture resistant and does not support Canon’s 1.4x or 2x extenders.

Overall, if you need a single lens for your travels, the Canon RF 24-240mm F4-6.3 IS USM is highly recommended.

12. Canon RF 100-400mm F5.6-8 IS USM

The Canon RF 100-400mm F5.6-8 IS USM is a full-frame telephoto lens weighing just 22.4 oz. / 1.4 lb. / 635g. On an APS-C camera like the Canon EOS R50, its full-frame equivalent focal length is 160-640mm.

If you’re seeking a compact telephoto lens for sports and wildlife photography with your R50, this zoom lens is an excellent choice.

Powered by Canon’s Nano USM focus motor, the autofocus delivers high-speed focus and accuracy throughout the focal range. The lens features 5.5 stops of Image Stabilization.

The zoom lens offers a focal length of 100-400mm (160-640mm full-frame equivalent) with a variable maximum aperture of F5.6-8, and a minimum aperture of F32 at 100mm and F45 at 400mm. The lens extends to zoom.

It has a minimum focusing distance of 88cm and a maximum magnification of 0.41x.

Additionally, the lens supports Canon’s RF 1.4x and 2x Extenders. Using the 1.4x extender, the focal length increases to 140-560mm and the aperture to F8-11. With the 2x extender, the focal length extends to 200-800mm and the aperture to F11-16.

Canon USA’s Rudy Winston takes a closer look at the Canon RF 100-400mm F5.6-8 IS USM lens in this video.

The Canon RF 100-400mm F5.6-8 IS USM lens is constructed with 12 elements in 9 groups and features 9 aperture blades, along with a 67mm front filter thread.

The lens includes dedicated zoom, focus, and control rings, an MF/AF toggle switch, and an image stabilization (IS) on/off switch. It also has a zoom lock switch that secures the lens at 100mm to prevent lens creep while walking.

The lens measures approximately 3.13 inches (79.5mm) in diameter and 6.48 inches (164.7mm) in length when retracted. When fully extended, it measures around 9.51 inches (241.7mm). It weighs 22.4 ounces (635g or 1.4 pounds).

Sadly there is no lens hood included so you will need to purchase the Canon ET-74B separately (B&H). We would strongly recommend purchasing the lens hood for this lens as it will help to prevent lens flare and also protect the front element of the lens from accidental drops.

13. Canon RF 800mm F11 IS STM

The Canon RF 800mm F11 IS STM is a full-frame telephoto prime lens offered at a very affordable price. On an APS-C camera like the Canon EOS R50, it provides a full-frame equivalent focal length of 1280mm.

This 800mm F11 lens is an excellent choice for shooting wildlife or aviation, especially under sunny skies.

Powered by Canon’s STM focus motor, the lens offers smooth and quiet autofocus, along with 4 stops of Image Stabilization.

As a prime lens, it has a fixed focal length of 800mm (1280mm full-frame equivalent) and a fixed aperture of F11, with no adjustable aperture blades. The lens needs to be extended before shooting.

The minimum focusing distance is 6m, with a maximum magnification of 0.14x.

Additionally, the lens is compatible with Canon’s RF 1.4x and 2x Extenders. Using the 1.4x extender, the focal length increases to 1120mm with an aperture of F16, while the 2x extender boosts the focal length to 1600mm with an aperture of F22.

For further information you can watch this video from Canon that features both the 800mm and the 600mm versions of this lens.

And also this video from video by Sabine Stols from Pangolin Photo Safaris.

The Canon RF 800mm F11 IS STM lens is constructed with 11 elements in 8 groups and features no aperture blades, helping to keep the weight, size, and cost down. It has a 95mm front filter thread.

The lens includes a focus and control ring, an MF/AF toggle switch, an image stabilization (IS) on/off switch, and a focus distance limiter switch with two settings (Full, 20m – Infinity). Additionally, it has a rotation-type lock to prevent the lens from extending.

The lens measures approximately 4 inches (101.6mm) in diameter and 13.85 inches (351.8mm) in length when extended for shooting, and around 11.09 inches (281.8mm) when retracted. It weighs 44.4 ounces (1260g or 2.77 pounds).

There is no lens hood included so you’ll need to purchase the Canon Lens Hood ET-101 (B&H | Amazon) which we would strongly recommend for this lens to avoid flare and help to protect the front lens element.

What To Consider When Choosing a Lens

Here’s a short guide on what to considering when choosing a lens for the Canon EOS R50.

• Focal range: The focal length of a lens determines its angle of view. For instance, a wide-angle lens typically has a focal length between 12-24mm, making it ideal for capturing landscapes, astrophotography, architecture, and real estate. On the other hand, telephoto lenses, which have focal lengths of 100mm, 200mm, or even 400mm, are perfect for bringing distant subjects closer, making them a great choice for sports and wildlife photography.
• Aperture: Aperture refers to the opening in a lens’s diaphragm that allows light to pass through. It is measured in f-stops, such as f/2.8, f/4, and f/5.6. A smaller f-stop number indicates a wider aperture. For example, an f/2.8 lens, which has a wide aperture, is ideal for indoor and low-light photography. However, lenses with such wide apertures tend to be more expensive.
• Prime or zoom: A prime lens has a fixed focal length, meaning you need to physically move closer or farther from your subject to change the framing. In contrast, a zoom lens lets you switch between different focal lengths, such as 100-500mm, by simply rotating the zoom ring. While prime lenses generally offer superior image quality, modern zoom lenses also provide excellent image quality, with some even rivaling or surpassing prime lenses.
