Pros
- •Compact and lightweight design, making it easy to carry around for travel, wildlife, or sports photography.
- •Versatile zoom range reaching up to 400mm, allowing for close-up shots from a distance.
- •Fast Nano USM focusing for smooth and quick autofocus performance.
- •Up to 6 stops of Coordinated Image Stabilization with compatible EOS R cameras, ensuring sharper images at long focal lengths.
- •Incorporates Ultra Low Dispersion lens elements that help minimize chromatic aberration and produce crisp, colorful images.
- •Accepts RF1.4x and RF2x tele extenders, boosting effective focal lengths to 560mm and 800mm.
- •Control ring allows quick adjustments to shutter speed, aperture, or other settings without fumbling.
- •Designed specifically for EOS R Series cameras, ensuring optimal compatibility and performance.
- •Similar in size to the popular EF 70-300mm, but with greater reach.
- •Great for capturing wildlife, sports, and travel subjects with ease.
Cons
- •Aperture range of f/5.6-8 means less light intake, which could limit shooting in low-light situations.
- •The maximum aperture at 8 is relatively narrow, impacting depth of field control and low-light performance.
- •Not the most affordable telephoto option if you need a lens primarily for low-light conditions or shallow depth of field.
- •Some users noted that the variable aperture can be restrictive for certain creative shots.
- •While lightweight, the lens may still feel somewhat bulky for extended handheld use over long hours.
- •Image quality is good but not quite on par with professional-grade prime telephotos, especially at the edges.
- •No tripod collar included, which might be inconvenient for very long exposures or heavy tripod use.
- •Some users mentioned that autofocus can occasionally hunt in tricky lighting.
- •Not a constant aperture lens, so exposure may vary as you zoom.
- •The aperture range may feel limiting if you prefer more control over depth of field or work mainly in low-light conditions.
Bottom Line
This lens offers a versatile, lightweight telephoto zoom with fast autofocus and excellent extender compatibility, ideal for wildlife, sports, and travel photography—especially if image stabilization and portability are priorities. However, its variable aperture and less optimal low-light performance may lead enthusiasts to consider alternatives like the RF100-400mm F4.5-5.6L IS USM for more consistent aperture control and higher optical quality.
