Product information:
How it works
The extender mounts between your RF camera body and RF lens, multiplying the lens focal length by 1.4x. That additional reach helps you frame distant subjects more tightly without swapping to a heavier telephoto. It maintains electronic connections so autofocus, aperture control and exposure metering continue to function, although performance varies with specific lens and camera combinations. Note that a 1.4x extender typically reduces the effective maximum aperture by one stop, which can affect autofocus performance in some setups.
Design and handling
With a low-profile footprint, approximately 71.2 mm in diameter and 20.3 mm in height, and a weight of 225 g, the extender is designed to be unobtrusive on your rig. The white and black finish complements Canon RF lenses and the clear 1.4x marking makes it easy to identify in your bag. Its compact form helps maintain balance on many camera and lens setups and makes it simple to add reach quickly on location.
Practical use and considerations
Use the extender when you need more focal length for press, wildlife or sports work and prefer to avoid carrying an additional lens. Before purchase, verify compatibility with your RF lenses and camera body, and be aware that adding an extender can alter autofocus speed and exposure behavior. Consider how the extra reach influences handling and stabilization for your typical shooting scenarios.
