Fotga DP500 III 15mm to 19mm Quick Release Rail Rod Clamp - Adapt 15mm

In this review the Fotga DP500 III 15mm to 19mm Quick Release Rail Rod Clamp is examined for filmmakers who need to adapt a Fotga DP500III 15mm quick release follow focus to a 19mm rod system. The bottom line: this adapter converts the quick release mount so you can keep an existing 15mm follow focus and use it on 19mm rods, saving the cost and hassle of buying a new follow focus. For anyone running mixed rod sizes on a shoot or upgrading rigs, it is a targeted, practical accessory.

Key Features

• Quick release compatibility: The clamp is designed for the Fotga DP500III quick release follow focus system so you can attach and detach the unit rapidly during a shoot.
• 15mm to 19mm conversion: It converts a 15mm follow focus to work with a 19mm film system, allowing cross-compatibility between rod standards without replacing your follow focus.
• Compact footprint: With an overall mount length of 140mm and a 12mm inner track width, the adapter is compact enough to fit tidy rig builds while maintaining secure contact.
• Clear mounting centers: The center distance between the two 19mm mount points is 105mm and between the 15mm points is 60mm, providing precise alignment when fitting to rods.
• Tool-free operation: The quick release plate mount allows for easy installation and removal of the follow focus, which helps speed camera changes and reduces downtime.

Who It's For

This part is aimed at independent filmmakers, camera assistants, and videographers who already own a Fotga DP500III or compatible DP3000 quick release follow focus and want to use it on rigs built around 19mm rods. It is especially useful for small crews who need to standardize accessories across cameras that use different rod diameters.

It is not intended for users of non-quick-release Fotga mounts or for follow focus units from other brands unless they explicitly match the mount dimensions. If your follow focus uses a standard non-quick-release mount, you should look for a direct 19mm compatible follow focus or a different adapter confirmed to fit your model.
