Modular lens replacement foot OF-C-T for Canon EF & RF & Sony FE telephoto lenses with Wimberley P-35 (127 mm)

Modular replacement lens foot OF-C-T with Wimberley P-35, precise balance for long telephoto lenses

You probably know this: telephoto powerhouses like a Canon RF 600mm f/4L IS USM or a Sony 400mm f/2.8 GM OSS FE SEL400F28GM are an optical dream, but on a tripod they often feel a bit wobbly or unbalanced without the right foot. This is exactly where the modular replacement lens foot OF-C-T with the 127 mm Wimberley P-35 quick-release plate comes in, bringing your Canon EF, Canon RF or Sony FE telephoto lenses into a perfectly balanced, stable working position.

The OF-C-T replaces the original lens foot and, together with the Wimberley P-35 base plate, forms a stable, well thought-out unit that has been specially developed for long focal lengths in everyday photography, where every small vibration becomes visible. For wildlife, sports, birds in flight or calm landscape scenes with super-telephoto lenses, this replacement foot is made to work reliably for a long time without making a fuss about it.

Compatible with many lenses, optimized for Canon EF, Canon RF and Sony FE telephotos

The modular replacement lens foot OF-C-T is compatible with many telephoto lenses, especially with popular professional lenses from Canon and Sony. These include, among others, the Canon EF 400mm f/2.8 L IS III and Canon EF 600mm f/4 L IS III USM, which are almost standard equipment in reportage and sports photography. The foot also fits seamlessly on the Sony 400mm f/2.8 GM OSS FE SEL400F28GM from 2018 and the Sony 600mm f/4 GM OSS FE SEL600F40GM from 2019, which play a central role in the Sony ecosystem for action and wildlife photography.

On the Canon RF side, the OF-C-T covers a whole range of modern super-telephoto lenses. These include the Canon RF 400mm f/2.8L IS USM 2021, Canon RF 600mm f/4L IS USM 2021, Canon RF 800mm f/5.6L IS USM 2022 and Canon RF 1200mm f/8L IS USM 2022. The versatile Canon RF 100-300mm f/2.8 L IS USM 2023, which is increasingly seen in sports and event photography, can also be used very comfortably on a tripod with this replacement foot.

This means you don’t have to look for a separate, special solution for every telephoto lens, but can use a modular system to balance several lenses precisely and reproducibly on your tripod head. That saves time, nerves and, in the long run, money.

Best materials and manufacturing quality, engineered for tough photo assignments

With the OF-C-T we rely on top-quality materials and manufacturing, because long telephoto lenses are not only heavy, but also sensitive to the smallest movements. The base is made from high-quality metal and precisely machined so that it fits exactly onto the lens mount without unwanted tolerances. The 127 mm Wimberley P-35 quick-release plate forms the stable base onto which the foot is screwed.

The surfaces are robustly finished so that the replacement foot retains its shape and function even with frequent setup and teardown, transport in a backpack or car trunk, and regular use in the field. Especially with long focal lengths, where you often sit for hours in a hide or work on the sidelines of a playing field, a reliable, precisely manufactured foot is more than just a comfort feature – it is a real working tool.

The fit to the supported Canon EF, Canon RF and Sony FE telephoto lenses has also been carefully tuned. The OF-C-T sits firmly on the lens without binding, allowing safe handling when carrying and positioning the camera-lens combination on the tripod head.

ARCA-compatible, ready to use in common quick-release systems

The modular replacement lens foot OF-C-T is fully ARCA-compatible in design. The 127 mm Wimberley P-35 base plate has a dovetail profile that can be clamped into high-quality ARCA-compatible quick-release clamps, as commonly found on many gimbal heads, ball heads and video tilt heads in the professional sector. This allows you to mount your Canon EF, Canon RF or Sony FE telephoto lenses quickly and securely on your tripod without additional adapters or intermediate plates.

Thanks to the ARCA-compatible design, switching between different setups is very straightforward. For example, you can quickly switch from a gimbal head to a sturdy ball head without having to remove the plate. This is particularly practical when you switch back and forth between action subjects and calmer scenes, or spontaneously change from tripod use to another setup.

All screws and tools required for mounting included, ready to go without additional purchases

So that you can mount the replacement foot on your lens without detours, all screws and tools required for installation are included. You receive the lens base OS-C-T for Canon EF, Canon RF and Sony FE telephoto lenses, the matching 127 mm Wimberley P-35 quick-release plate, M4 mounting screws in various lengths, and M3 safety stop screws.

The M4 mounting screws ensure a stable connection between the base and the lens, while the M3 safety stop screws can be attached at the ends of the ARCA dovetail plate. These safety stop screws prevent accidental slipping out of the quick-release clamp if the clamp is not fully closed or opened too far. This keeps your valuable camera-lens combination reliably secured even in hectic situations.

A DW-03 multi-tool is also included to make installation and later adjustments easier. You don’t have to search for the right hex keys, but can start right away and adapt the OF-C-T to your telephoto lenses.

Movable base on the plate, optimal center of gravity for every combination

One of the key features of this modular system is that the base is movable on the plate. This means that the lens base can be shifted along the entire length of the Wimberley P-35 plate and fixed in the desired position. This allows you to fine-tune the center of gravity of your lens-camera combination very precisely.

Whether you are working with a heavy camera with battery grip or a lighter body without a grip, whether you are using a teleconverter or not, whether you mount a Canon RF 800mm f/5.6L IS USM or a Sony 600mm f/4 GM OSS FE SEL600F40GM, the balance can be adjusted so that the system almost naturally stays level on the tripod head. This greatly facilitates handling on a gimbal head and reduces the strain on your hands and arms.

Especially during long wildlife sessions or fast-paced sports events, this flexible center-of-gravity adjustment becomes very noticeable. You can balance the setup so that you can track your subject with minimal effort, which significantly improves your hit rate at long focal lengths.

Modular design of base and plate, flexibly adaptable to different setups

The OF-C-T follows a modular design of base and plate. Instead of using a one-piece replacement foot that only offers a fixed position, this system separates the actual lens base from the quick-release plate. The base is mounted on the Wimberley P-35 plate and can be moved along its entire length.

This modular construction allows you to choose the distance between the lens and the dovetail plate so that balance and handling are optimal. If you frequently work with teleconverters, for example, or switch between different camera bodies, you can adjust the position of the base on the plate without having to replace the entire system.

The result is a very flexible solution that adapts to your individual needs instead of forcing you into a rigid configuration. You can keep fine-tuning the setup over time as your equipment or working style changes.

Stable base for professional telephoto photography with Canon and Sony

With the modular replacement lens foot OF-C-T and the Wimberley P-35 quick-release plate, you get a solid, field-tested base for professional telephoto photography. The combination of precise manufacturing, ARCA-compatible dovetail plate, movable base and well thought-out scope of delivery with M4 mounting screws and M3 safety stop screws makes this system a reliable partner in the field.

Whether you use a Canon RF 1200mm f/8L IS USM for distant subjects, a Canon RF 100-300mm f/2.8 L IS USM for dynamic sports shots, or stand on the sidelines with a Sony 400mm f/2.8 GM OSS FE SEL400F28GM, the OF-C-T ensures that your setup remains steady, secure and well balanced on the tripod head. This allows you to focus on your subject instead of constantly struggling with the equipment.

In the end, it’s about your gear working reliably in the background while you create the images you envision. The modular replacement lens foot OF-C-T with Wimberley P-35 contributes exactly to this by holding long Canon EF, Canon RF and Sony FE telephoto lenses securely, flexibly and comfortably on the tripod.
