Pre-Owned Kenko Teleplus C-AF 1.5 Teleconverter Canon EF Mount - SWO2H96

1.5x Focal Length Multiplication: Turns a 300mm lens into a 450mm equivalent telephoto lens.
1-Stop Light Loss: Cuts incoming light transmission by exactly one f-stop (e.g., an f/2.8 lens effectively becomes an f/4 lens).
SHQ (Super High Quality) Glass: Features multi-coated optical elements that retain center sharpness far better than generic third-party converters.
Electronic Communication (C-AF): Passes autofocus, aperture controls, and EXIF metadata information directly from the lens to the Canon camera body

Autofocus Limitations: Reliable autofocus functions correctly on most classic Canon bodies as long as your attached master lens has a maximum open aperture of f/4 or brighter (resulting in a combined aperture of f/5.6 or faster). If the combined aperture value drops past f/5.6, switching to manual focus tracking is highly recommended

System Disabling Rule: According to Kenko Global technical documentation, you should proactively turn off in-camera optical lens corrections, Digital Lens Optimizers, and AF Micro-adjustments when using legacy teleconverters to prevent electronic translation communication glitches between older third-party chips and modern camera processors.

Macro Function Bonus: When paired with a dedicated macro prime lens (like a 100mm f/2.8), it retains the exact same close-focus distance while narrowing the field of view. This allows you to surpass standard 1:1 macro magnification and enter true micro-photography layouts without moving physically closer to your subject
