Canon Drop-In Gelatin Filter Holder 52 (WIII)

The Canon 3051C001 is a drop-in gelatin filter holder designed for photographers who use the EF 400mm f/2.8L IS III USM or EF 600mm f/4L IS III USM super-telephoto lenses and need a straightforward way to add cut gel filters. By inserting at the rear of the lens, the holder lets you adjust color or control challenging light without removing the lens from the camera body.

The holder accepts 52 mm cut gel filters and secures them with a reliable clamping mechanism, so you can swap filters quickly while knowing they will stay firmly in place during bursts of action, long tracking shots, or any situation where movement can compromise gear. Its drop-in design keeps the installation process fast, which is essential when light changes rapidly in the field.

Weighing only 0.07 pounds and measuring roughly 2 inches across, the filter holder adds minimal bulk to a lens setup that may already sit on a monopod or tripod. This low-profile approach makes it a practical accessory for sports and wildlife photographers who spend long hours tracking distant subjects and cannot afford unnecessary weight.

Whether you want to fine-tune white balance, add subtle warming, or correct color casts caused by mixed lighting, the Canon 3051C001 offers a dependable, portable solution that integrates smoothly with two of Canon’s flagship super-telephoto lenses.
