Modular replacement lens foot OF-C-T 130 for Canon EF & RF & Sony FE telephoto lenses OP-130 (130 mm) 2 x QD

Modular replacement lens foot OF-C-T 130 OP-130 (130 mm) for Canon EF, Canon RF and Sony FE telephoto lenses

Working with long telephoto lenses is fantastic, but let’s be honest: the standard lens foot is often more of a compromise than a pleasure. This is exactly where the modular replacement lens foot OF-C-T 130 comes in. It gives you a stable, finely adjustable base for your Canon EF, Canon RF and Sony FE telephoto lenses and makes your camera-lens combination significantly easier to handle.

The OF-C-T 130 is specifically matched to high-end super-telephoto lenses such as the Canon EF 400mm f/2.8 L IS III or the Canon EF 600mm f/4 L IS III USM, as well as the Sony 400mm f/2.8 GM OSS FE [SEL400F28GM] and Sony 600mm f/4 GM OSS FE [SEL600F40GM]. Current Canon RF teles such as 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), Canon RF 1200mm f/8L IS USM (2022) and the Canon RF 100-300mm f/2.8 L IS USM (2023) also find a perfectly fitting, solid mount here. In short: a replacement foot that takes your high-end optics seriously.

Compatible with many lenses, flexible for your telephoto lineup

The OF-C-T 130 has been designed to work with a whole range of Canon EF, Canon RF and Sony FE telephoto lenses. You therefore don’t have to look for a completely different solution for each individual lens, but can build up your equipment in a sensible and long-term way. The replacement foot really shows its strengths with large primes such as the Canon EF 400mm f/2.8 L IS III or the Sony 600mm f/4 GM OSS FE [SEL600F40GM], because it significantly improves balance on the tripod and noticeably eases everyday handling.

Even when you switch between a Canon RF 400mm f/2.8L IS USM, RF 600mm f/4L IS USM or an RF 800mm f/5.6L IS USM, the operating feel remains familiar. The modular design ensures that you can repeatedly adapt your lens-camera combination without having to completely reconfigure your setup each time. For photographers who regularly switch between wildlife, sports and landscape, this is a very pleasant side effect.

Best materials and manufacturing quality, built for tough use

For the OF-C-T 130 we rely on robust, precisely manufactured components that function reliably even under intensive use. The material is designed for high rigidity and dimensional stability so that your Canon RF 1200mm f/8L IS USM or a heavy Sony 400mm f/2.8 GM OSS FE [SEL400F28GM] is held securely, even if you are frequently on the move or working outdoors in wind and weather.

The surfaces are cleanly finished, edges are pleasantly deburred, and the fits between base and main plate are designed so that you can repeatedly loosen and reposition the foot without any play developing. You can feel this immediately when tightening the screws: nothing creaks, nothing feels improvised. It simply feels like a part that belongs on a professional telephoto lens.

QD-compatible with 2 strap anchor mounts for double safety, more margin when carrying

The OF-C-T 130 has two QD-compatible strap mounts that provide you with a particularly secure carrying option. Thanks to the two QD strap anchor mounts, you can either use a strap with two anchor points or set up an asymmetrical carrying position that better suits your way of working. Especially with long focal lengths, when you are carrying a Canon RF 800mm f/5.6L IS USM or a Canon EF 600mm f/4 L IS III USM on your body, this double security is a real plus.

To use the QD mounts, you need a suitable strap with QD strap anchors. Without these special anchors, the system will not function as intended, so it is worth looking at corresponding straps that are designed for QD connections.

ARCA-compatible, mount directly on the quick-release clamp

The main plate of the OF-C-T 130 is ARCA-compatible. This means you can clamp the replacement foot directly into a suitable ARCA quick-release clamp without additional adapters or intermediate plates. In practice this means: fewer parts, less play, less weight and a faster switch between tripod, gimbal or monopod.

If you already work with ARCA systems, the OF-C-T 130 integrates seamlessly into your existing workflow. You simply clamp your Canon RF 100-300mm f/2.8 L IS USM or a Sony 600mm f/4 GM OSS FE and can start shooting immediately instead of having to rebuild your setup in a cumbersome way. For sports and wildlife photographers who are often under time pressure, this direct compatibility is a very practical advantage.

Developed by us, practical design from real photographic experience

The modular construction of base and main plate is not a theoretical experiment, but the result of many assignments with heavy telephoto lenses. We deliberately decided against a rigid, one-piece replacement foot because such solutions are often too inflexible in practice. Instead, we designed the base to be movable along a longer main plate so that you can really fine-tune the center of gravity of your lens-camera combination.

Whether you are working with a heavy camera with battery grip, a lighter mirrorless camera without grip, or with a teleconverter in between, the base can be moved along the main plate. This allows you to position the lens over the dovetail plate so that the combination is cleanly balanced on the tripod head. Especially with long focal lengths, where even a small shift has noticeable effects, this flexibility makes a clear difference.

All screws and tools required for mounting are included, ready for immediate use

So that you don’t first have to look for suitable screws or tools, we supply the modular replacement lens foot OF-C-T 130 fully ready for assembly. The set includes the lens base OS-C-T for Canon EF, Canon RF and Sony FE telephoto lenses, the matching quick-release plate in the chosen version, M4 mounting screws in various lengths, and M3 safety stop screws.

You can remove the standard foot of your lens and mount the OF-C-T 130 directly. The different lengths of the M4 mounting screws ensure that you can choose the appropriate fastening for the respective lens models. The included safety stop screws prevent the plate from accidentally sliding out of the quick-release clamp and thus further increase the safety of your equipment.

Movable base on the main plate, precisely adjust the center of gravity

A key feature of the OF-C-T 130 is the base on the main plate, which can be moved along the entire length. This allows you to optimally adjust the position of the lens over the dovetail plate to the center of gravity of your lens-camera combination. For example, if you use a camera with a battery grip, the center of gravity shifts significantly to the rear, while a lighter camera without grip or the use of a teleconverter creates different requirements again.

With the movable base you can compensate for these differences without needing a different plate or a new foot each time. You simply loosen the fastening, move the base along the main plate and tighten it again. This gives you neutral balance on the tripod head, which provides noticeably more control, especially for panning and longer exposure times.

Well thought-out features for professional telephoto lenses

The modular replacement lens foot OF-C-T 130 is tailored to everyday life with large telephoto lenses. It safely supports heavy optics such as a Canon RF 600mm f/4L IS USM or a Sony 400mm f/2.8 GM OSS FE and at the same time offers the necessary flexibility to accommodate different camera bodies, converters and working styles. The combination of ARCA-compatible main plate, QD-compatible strap mounts, movable base and included M4 mounting screws makes the foot a very versatile tool for ambitious and professional users.

If you don’t just want to mount your super-telephoto lenses somehow, but really want to balance them cleanly and carry them safely, the OF-C-T 130 is a technically sober but in everyday use very noticeable improvement over many standard solutions.
