Canon IFC-40AB II USB Interface Cable

This Canon IFC-40AB II USB Interface Cable connects the WFT-E7A wireless transmitter to compatible Canon EOS cameras including the 7D Mark II, 5DS, 5DS R and 5D Mark IV. It is built for photographers who need a dependable wired link for tethered shooting or image transfer workflows. The cable provides a direct data path between the transmitter and the camera body. Its durable construction suits regular professional use in studio or location environments.

Firmware dependency limits compatibility

The WFT-E7A transmitter must run firmware version 1.1.0 or later for this cable to function correctly. Without that update the connection will not operate as intended. This requirement creates a practical limit: older transmitter units cannot use the cable until updated. Buyers who cannot update their transmitter firmware should not purchase this cable.

Compatibility with listed EOS models

The single specification that decides fit is whether the camera is an EOS 7D Mark II, 5DS, 5DS R or 5D Mark IV paired with a WFT-E7A (ver.1) transmitter on firmware 1.1.0 or later. If the camera model or transmitter version differs, the cable will not provide the intended connection.

Questions about this item

Which cable version works with my WFT-E7A transmitter and EOS 5D Mark IV?

The IFC-40AB II is the correct version; it requires the transmitter to run firmware 1.1.0 or later for full compatibility with the 5D Mark IV, 5DS, 5DS R and 7D Mark II.

What does the 40 in the model name mean once the cable is plugged into my camera?

It is the model identifier for this specific USB interface cable; it does not indicate length, speed or any other performance figure.

What USB standard does this cable use and what does that limit in practice?

It is a standard USB cable for the WFT-E7A; the transmitter's own USB port and firmware determine the actual transfer rate, not the cable itself.
