Canon RF100-400 IS USM Lens

No, this lens is specifically designed for Canon's EOS R series mirrorless cameras. It will not fit older Canon DSLR models with EF or EF-S mounts.

The lens provides up to 5.5 stops of shake correction on its own. When paired with an EOS R camera body that features In-Body Image Stabilization, such as the R5 or R6, that performance increases to 6 stops, making handheld telephoto shooting much easier.

Yes, this lens is compatible with Canon's RF 1.4x and RF 2x tele extenders. Using these will extend your reach to 560mm or 800mm, respectively, though it will reduce the maximum aperture of the lens.

Absolutely. Its compact, lightweight design makes it significantly easier to carry and hold for long periods compared to traditional telephoto lenses, and the Nano USM autofocus is fast enough to track moving subjects effectively.

The customizable Control Ring allows you to adjust exposure settings like aperture, shutter speed, or ISO directly from the lens. It provides a tactile way to change settings without needing to navigate through your camera's menu system while looking through the viewfinder.

With a variable aperture of f/5.6-8, this lens is best suited for well-lit environments or daytime shooting. You may need to increase your camera's ISO settings when shooting in dim conditions or during the late afternoon to maintain a fast enough shutter speed.
