Frequently Asked Questions - OCS-C6 Vello

What is the Vello OCS-C6 Off-Camera TTL Flash Cord used for?

It allows you to mount a flash off the camera while maintaining full TTL (Through The Lens) communication, enabling automatic exposure control for natural-looking lighting without harsh shadows.

Is the cord compatible with all cameras?

It is compatible with cameras that have a standard hot shoe and support TTL flash metering. However, Vello makes different models for different camera brands; check your camera's manual for specific compatibility.

How do I mount the cord to my camera?

Attach the camera-side hot shoe to your camera's hot shoe, ensuring it faces forward (toward the lens). If your model has a locking mechanism, use it to secure the connection.

Can I mount the flash on a light stand or tripod?

Yes. The off-camera shoe has a 1/4";-20 threaded socket that can be mounted to a compatible tripod, boom, or light stand. It can also be attached to an accessory shoe.

Do I need to turn off devices before connecting?

Yes. Always switch off both the camera and flash before attaching or removing the cord to prevent electrical damage.

How long is the cord?

The cord is coiled; approximate length when coiled is 12 in (30 cm) and can stretch to about 36 in (91 cm). Avoid overstretching to prevent instability.

Is the cord weather-resistant?

No. It is not water-resistant. Keep it away from rain, snow, and high humidity.

How do I clean the cord?

Use a soft, dry cloth to wipe the cord and connections. Do not use solvents or liquids.

What is the warranty period?

Vello offers a one-year limited warranty from the original purchase date, covering defects in materials and workmanship under normal use.

Can I connect multiple cords together (daisy-chain)?

No. Do not attempt to daisy-chain flash cords, as it may damage the equipment and void the warranty.

INTRODUCTION

Thank you for choosing a Vello Off-Camera TTL Flash Cord. This TTL flash cord allows you to set up a portable flash for off-camera lighting while retaining all of the TTL flash functionality achieved in modern digital cameras.

Off-camera lighting reduces the harsh shadows of direct on-camera flash and gives your photos more natural lighting. TTL (through the lens) functions of modern cameras handle exposure calculations so you can concentrate on composing the image. Because the light from the flash is measured through the lens by the camera, there is no need for exposure calculations or a separate light meter.

Do not attempt to modify or disassemble the cord, shoe, or contacts. Do not attempt to "daisy-chain" flash cords.

This device is not water-resistant. Do not immerse in or expose to water, rain, or snow.

Do not clean the cord with solvents. Use a soft, dry cloth to clean the cord and connections.
