Pros & Cons
Pros
- Lightweight at approximately 2.05 lbs (930g), making it easier to carry for extended periods.
- Great value for money, often available refurbished for around $400.
- Acceptable optical quality, with several users noting sharp images especially in good light conditions.
- Compact size allows easy handling and storage, fitting in smaller camera bags.
- The RF 600mm f/11 IS STM is praised for its portability compared to traditional supertelephoto lenses.
- Good for bird photography during bright conditions due to lightweight and manageable form factor.
- The lens performs well for moon photography as noted by multiple users.
Cons
- Limited maximum aperture of f/11 restricts usability in low light conditions, requiring higher ISOs for adequate shutter speeds.
- Some users reported difficulty with autofocus accuracy, especially in lower light scenarios.
- Fixed aperture becomes a challenge for capturing fast-moving subjects in variable lighting.
- Long minimum focus distance restricts getting close to subjects, resulting in missed opportunities for detailed shots.
- Lack of versatility compared to zoom lenses for changing composition quickly in dynamic wildlife situations.
Verdict
The Canon RF 600mm f/11 IS STM is highly regarded for its lightweight and compact design, making it a popular choice for hobbyist wildlife photographers seeking affordable reach. However, its limited maximum aperture and fixed focal length pose challenges in low light and flexible shooting scenarios, leading many users to recommend considering zoom options for greater versatility.

Frequently Asked Questions
Is the RF 600mm f/11 IS STM compatible with Canon's RF teleconverters?
No, this lens does not support Canon RF teleconverters, such as the RF 1.4x or 2x Extenders. The lens design and fixed f/11 aperture do not permit teleconverter usage, so you're limited to its native 600mm focal length.
Can I use the RF 600mm f/11 IS STM handheld, or do I need a monopod?
The lens is specifically designed for handheld use, thanks to its low weight (930g) and effective built-in Image Stabilization. For most users, a monopod is not necessary, though it can help for all-day sessions or with very high-resolution bodies.
How does the lens perform for bird and wildlife photography in low light?
Performance drops significantly in low light due to the slow f/11 aperture. You'll need to use higher ISO values and slower shutter speeds, which can impact image quality and camera autofocus performance. It is best suited for daylight shooting.
What are the main differences between this lens and Canon's professional 600mm f/4 models?
Canon's 600mm f/4 lenses are vastly larger, heavier, and much faster (f/4 vs. f/11), offer fully weather-sealed construction, lightning-fast autofocus, superior bokeh, and professional durability-but cost more than ten times as much. The RF 600mm f/11 trades most of these for price, portability, and accessibility.
Can I achieve a shallow depth of field with this lens?
While the maximum f/11 aperture limits overall background blur compared to faster supertelephotos, the long 600mm focal length still provides plenty of subject isolation and soft backgrounds for most wildlife, bird, or distant portrait work, especially when your subject is far from the background.
Does the lens have weather sealing?
No, the Canon RF 600mm f/11 IS STM does not have weather sealing. It's important to protect the lens from rain, dust, and harsh conditions, especially in outdoor environments.
