Modular replacement lens foot OF-C-T for Canon EF & RF & Sony FE telephoto lenses (with Wimberley P-10) Wimberley P-10 (84 mm)

QD-compatible with 2 strap anchor mounts for double security

If you’re out and about with a Canon RF 600mm f/4L IS USM or a Sony 400mm f/2.8 GM OSS FE, you know how quickly such a telephoto monster becomes a real challenge as soon as you start moving. The modular replacement lens foot OF-C-T therefore comes with two QD strap mounts that give you a very stable carrying and safety solution. This allows you to attach your setup to a suitable strap using two QD strap anchors and distribute the load more evenly, which is particularly noticeable during longer assignments.

To use the QD strap mounts, you need a strap with suitable QD strap anchors, which you can purchase separately here you can find suitable QD strap anchors. The dual mount ensures that your Canon EF 600mm f/4 L IS III USM or Canon RF 800mm f/5.6L IS USM is not only comfortable to carry, but also reliably protected against unwanted tilting or twisting. In everyday use, it simply feels reassuring when you notice that nothing wobbles or “somehow only half” holds, but really sits solidly.

ARCA-compatible for seamless integration into your tripod setup

The OF-C-T replacement foot is fully ARCA-compatible and therefore integrates cleanly into modern tripod systems based on Arca-style profiles. If you are already working with a high-quality quick-release clamp, you can use the foot directly without additional adapters or detours. This saves time and nerves and reduces potential sources of error during field setup.

Especially with long focal lengths such as the Canon RF 1200mm f/8L IS USM or the Sony 600mm f/4 GM OSS FE, a precise, play-free fit on the tripod head is crucial to minimize camera shake. The ARCA-compatible tripod plate of the system harmonizes with common clamps and quick-release heads, so you can quickly switch your setup from handheld shooting to tripod use.

If you are interested in the topic of ARCA and compatible quick-release systems in more detail, you can find more detailed information on ARCA-compatible solutions. This way you can build a system that fits together in the long term and does not consist of a lot of isolated solutions that only half harmonize with each other.

All screws and tools required for mounting are included

The modular replacement lens foot OF-C-T for Canon EF, Canon RF and Sony FE telephoto lenses arrives at your place fully equipped. You don’t have to rummage through your toolbox or search for suitable screws, because everything you need to mount it on your lens is included.

In the package you will find the lens base OS-C-T for Canon EF/RF and Sony FE teles, the matching Wimberley P-10 tripod plate with a length of 84 mm, M4 mounting screws in various lengths for secure attachment to your telephoto lens, as well as M3 safety stop screws. In addition, a DW-03 multi-tool is included as a free extra, allowing you to carry out the installation conveniently without having to organize any additional tools.

This allows you to convert your Canon EF 400mm f/2.8 L IS III or a Canon RF 100-300mm f/2.8 L IS USM directly after unpacking and replace the standard lens foot. No improvising, no “I’ll do it later when I’ve found the right hex key”, but a clearly structured conversion that can be implemented immediately.

Developed by us for demanding telephoto lens users

The modular replacement foot OF-C-T was developed by us because classic one-piece lens feet are simply not flexible enough for many real-world use cases. We took an in-depth look at the requirements of sports, wildlife and nature photographers who work with heavy telephoto lenses such as the Canon RF 400mm f/2.8L IS USM or the Sony 600mm f/4 GM OSS FE, and from this created a system that adapts to your equipment, not the other way around.

The modular design consisting of base and main plate allows you to precisely balance the center of gravity of your lens-camera combination. Whether you are working with a lightweight mirrorless camera without a battery grip or a massive DSLR with a large grip, whether a teleconverter is in between or not, the base can be moved along the main plate and fixed exactly where the center of gravity lies optimally above the tripod head.

We deliberately designed the concept so that it is not only suitable for a single lens, but covers several typical telephoto focal lengths. These include, among others, the Canon EF 600mm f/4 L IS III USM, the Canon RF 600mm f/4L IS USM, the Canon RF 800mm f/5.6L IS USM, the Canon RF 1200mm f/8L IS USM as well as the Sony 400mm f/2.8 GM OSS FE and the Sony 600mm f/4 GM OSS FE. This allows you to stay within one system even if you gradually expand your lens lineup or switch between EF and RF or Sony FE.

Best materials and manufacturing quality for maximum stability

With the OF-C-T we rely on top-quality materials and very precise manufacturing so that you can rely on your replacement foot even under intensive use. The components are made from high-grade metal alloys that provide high rigidity and load capacity without adding unnecessary weight. Especially with long focal lengths that you may be using for hours at a time, every gram that is used sensibly counts.

The surfaces are cleanly finished and made to be durable, so the foot continues to function reliably even after frequent clamping in the quick-release, transport in a backpack, or typical outdoor use with dust, moisture and temperature fluctuations. The fits between base and tripod plate are designed so that the base can be moved easily, yet can be fixed without play as soon as you have found the position that is ideal for your combination of camera, lens and possibly teleconverter.

In practice, this means that your Canon RF 100-300mm f/2.8 L IS USM or your Sony 400mm f/2.8 GM OSS FE sits solidly, without vibrations or unwanted oscillation, which directly translates into sharper images and more pleasant handling. You can simply tell when a part doesn’t just “somehow fit”, but is really well thought out and cleanly manufactured.

Wimberley P-10 (84 mm) tripod plate as a precise base

The modular replacement lens foot OF-C-T includes the Wimberley P-10 tripod plate with a length of 84 mm, which forms a solid and ARCA-compatible base for your telephoto lens. This tripod plate is designed to harmonize with common ARCA clamps while providing sufficient length to position the base flexibly.

The tripod plate is not just a simple adapter solution, but a central element of the modular system. The base can be moved along the main plate so you can set the center of gravity of your lens-camera combination precisely. Whether you are working with a Canon RF 400mm f/2.8L IS USM and a lightweight mirrorless camera or combining a Canon EF 600mm f/4 L IS III USM with a large body and teleconverter, the tripod plate gives you the leeway to adjust the balance on the tripod head so that the system does not tip forward or backward.

This makes handling on a gimbal, ball or video head significantly more pleasant, because you need to apply less holding force and movements overall become smoother and more controlled. Especially with dynamic subjects such as birds in flight or fast sports, a properly balanced combination is clearly noticeable.

Modular design with movable base for optimal center of gravity

One of the key features of the OF-C-T is the base on the main plate, which can be moved to allow optimal adjustment to the lens and the center of gravity of the lens-camera combination. This modular design goes far beyond what a classic, fixed replacement foot can offer.

You can move the base along the entire length of the tripod plate and thus find exactly the position at which your Canon RF 800mm f/5.6L IS USM or the Sony 600mm f/4 GM OSS FE is in perfect balance. Whether you are working with or without a teleconverter, change cameras or mount a battery grip, you can adjust the position of the base at any time without having to replace the entire system.

This makes the OF-C-T particularly suitable for photographers who use their equipment flexibly and do not want to buy a separate, rigid foot for every configuration. Instead, you adapt the existing replacement foot to your current combination, which in the long run is not only more convenient but also more economical.

Compatibility with Canon EF, Canon RF and Sony FE telephoto lenses

The modular replacement lens foot OF-C-T was specially developed for selected Canon EF, Canon RF and Sony FE telephoto lenses. The supported Canon EF lenses include, among others, the Canon EF 400mm f/2.8 L IS III and the Canon EF 600mm f/4 L IS III USM. On the RF side, the foot covers, among others, the Canon RF 400mm f/2.8L IS USM, the Canon RF 600mm f/4L IS USM, the Canon RF 800mm f/5.6L IS USM, the Canon RF 1200mm f/8L IS USM as well as the Canon RF 100-300mm f/2.8 L IS USM.

For Sony users, the replacement foot is suitable for the Sony 400mm f/2.8 GM OSS FE [SEL400F28GM] and the Sony 600mm f/4 GM OSS FE [SEL600F40GM]. This means the OF-C-T covers a large portion of the common super-telephoto lenses used in professional environments.

Thanks to this broad compatibility, the replacement foot is ideal for photographers who either use several telephoto lenses within one system or plan to switch from EF to RF in the future without wanting to purchase completely new accessories. You can therefore modernize your setup step by step while retaining a familiar, reliable base for tripod mounting.

Complete set for direct use on the lens

The modular replacement lens foot OF-C-T is delivered as a complete set so you can get started without detours. Included are the lens base OS-C-T for Canon EF/RF and Sony FE telephoto lenses, the Wimberley P-10 tripod plate with a length of 84 mm, M4 mounting screws in various lengths, the M3 safety stop screws as well as a DW-03 multi-tool as a free addition.

This allows you to quickly remove your standard lens foot and mount the new modular replacement foot. The different lengths of the M4 mounting screws ensure that you will find the right attachment for every supported lens without having to improvise. The DW-03 multi-tool allows you to carry out the installation even on the go or in a hotel room when you want to prepare your equipment for a new combination.

This turns a rather bulky standard foot (tripod plate) into a well-thought-out, ARCA-compatible system that can be precisely tailored to your way of working and connects your telephoto lenses to the tripod safely and comfortably.
