The Canon RF 100-400mm f/5.6-8 IS USM is a relatively affordable lens with a maximum aperture of f/5.6 to f/8. It has good image quality and handling, with a lightweight body. The autofocus is fast and silent, with a close focus distance. The main downside is the dark aperture, which may require shooting at high ISO levels.

It's a surprisingly good lens and highly recommended, despite its dark aperture. The close focus distance and fast autofocus are great features.

  • Good image quality and handling
  • Fast and silent autofocus
  • Lightweight body with a close focus distance

The Canon RF 100-400mm f/5.6-8 IS USM has good image quality, especially at the middle of the image.

The Canon RF 100-400mm f/5.6-8 IS USM is a relatively affordable lens with a maximum aperture of f/5.6 to f/8. It has good image quality and handling, with a lightweight body and a relatively small size. The autofocus is fast and silent, with a close focus distance. However, the dark aperture may require shooting at high ISO levels, and the lens does not come with weather sealing. The image quality is sharp and contrast are very good, especially at the middle of the image. The lens performs well across the zoom range, with images enjoying plenty of sharpness and contrast. However, the dark maximum aperture means that telephoto lens options will give much better background separation. Overall, the Canon RF 100-400mm f/5.6-8 IS USM is a surprisingly good and highly recommended lens, despite its limitations.

The dark maximum aperture may require shooting at high ISO levels, but overall, it is a good and highly recommended lens.
