Questions about DJI RS 4 Pro Combo

The accessories of the old DJI RSC 2 Combo are not fully compatible with the new RS 4 Pro. Some accessories such as multi-camera control cables are specifically designed for RS 2 and RSC 2 and do not work directly with the RS 4 Pro. However, there are accessories that are compatible with several DJI Ronin gimbals, including the RS 4 Pro, such as certain third-party handles (e.g. SmallRig Sling Handle). An official compatibility list shows that many RSC 2 accessories are not compatible with the RS 4 Pro or can only be used with restrictions. For specific accessories, we recommend checking the official DJI compatibility list or contacting DJI directly.

The portrait rail is already integrated in the design of the DJI RS 4 Pro. You don't need to buy the DJI RS 4 Pro Combo to shoot in portrait mode. The product allows you to easily switch between horizontal and vertical shooting without additional accessories.
