RF4 WD168 0.48X Auxiliary Objects Lens For Trinocular Stereo Zoom Microscopes

Assuming you’re referring to an RF 0.48x lens for a Canon RF mount camera, here are some general details:

1. Compatibility: RF lenses are designed specifically for Canon’s mirrorless cameras that feature the RF mount, such as the Canon EOS R series.

2. Focal Reducer: The “0.48x” indicates that this lens might be a focal reducer, also known as a speed booster. These adapters reduce the focal length of the lens attached to it and increase its speed, effectively giving you a wider field of view and more light-gathering capability.

3. Aperture: The maximum aperture of the lens would depend on the lens you’re using in combination with the focal reducer. However, generally, the speed booster improves the effective aperture by approximately 1.5 stops.

4. Manufacturer: Various manufacturers produce RF mount lenses and adapters, including Canon themselves, as well as third-party manufacturers like Sigma, Tamron, and others. Each may have its own specifications and features.
