Product Information

Full details

The SmallRig RA-F150 Fresnel Lens is designed for professional videographers and photographers who require precise beam control and increased light intensity from their Bowens-mount LED fixtures. Its primary benefit is the ability to amplify light output by up to 13.2 times while allowing for smooth zoom transitions, though its robust construction and dedicated cooling system make it a heavier addition to your lighting kit.

Extended Product Information

FAQs

Is the RA-F150 compatible with all Bowens mount lights?

It is designed for standard Bowens mount lights, specifically optimized for SmallRig RC series, but works with most third-party LED monolights with matching mounts.

Does the cooling system require a separate power supply?

No, the internal cooling system is powered by the light fixture it is attached to through the integration with the lamp head.

Can I use this with high-wattage COB lights?

Yes, the lens is built with high-temperature-resistant borosilicate glass and a triple cooling system to manage high-heat environments.

What is the weight of the unit?

The product itself weighs 1.5 kg (approximately 3.3 lbs).

How do I clean the Fresnel lens?

Use a dry microfiber cloth to wipe the surface. Avoid using liquid cleaners or abrasive materials that could damage the lens coating.

Does it come with a carrying case?

Yes, each unit includes a dedicated, shockproof storage bag.

Troubleshooting

The lens does not click into the Bowens mount securely.

Check the mount pins for debris and ensure the lens is aligned correctly before turning to lock.

The unit feels excessively hot during long usage.

Verify that the internal cooling fan is running; if not, disconnect power and inspect the vents for obstructions.

Beam shape appears uneven.

Ensure the light source is properly centered behind the lens and that the front glass is clean and free of smudges.

Pros and Cons

Pros

Significant increase in light intensity and throw
Easy one-handed operation for beam angle adjustments
Heat-resistant materials ensure long-term durability
Includes a durable, shockproof storage bag

Cons

Adds significant weight to your light stand
Requires careful handling due to the glass lens element
Takes up more space in gear bags compared to standard reflectors

Setup, Compatibility & Care

To set up the lens, simply align the three pins of the RA-F150 with the Bowens mount on your LED light, insert, and rotate clockwise until it clicks into place. Ensure the locking mechanism is fully engaged before positioning the light. Compatibility is broad thanks to the standard Bowens mount, though users should ensure their light stand is rated for the added weight of the lens. To maintain the unit, keep the Fresnel lens free of fingerprints and dust by using a clean microfiber cloth. Always store the unit in the provided shockproof bag when not in use to prevent scratching the glass or damaging the internal cooling fan housing.
