This Modified Ball Clamp with T-Knob from Ultralight is used to connect light arms to underwater camera rigs, or arm sections to each other, using 1" mounting balls. Featuring a modified design that permits greater side-to-side movement, this clamp measures 1.5" between the centers of the ball recesses. The splashy red anodized T-knob makes tightening and loosening the clamp easy, and it can be useful in the cinema industry for color-coding camera rigs.

Q: 1. Will the FB-52 handle a Nikon D300s with battery pack and 400 F3.5 Nikkor lens?

A: Yes, it handles up to 44lbs, more than enough to handle this kit well.

Q: 2. Please, I am requesting from other serious hobbyists and pros out there: Will the Really Right Stuff Ultralight L-Plate for Nikon D850 B&H # REBD850L MFR # BD850-L ULTRALIGHT L-PLATE work with the RRS BH-55 without any additional part or adapter for a strong connection between the two parts? I will be shooting landscapes in portrait mode with a Nikon D850 (without a grip.) I do not plan to do any stitching of panoramas in post. I will be shooting just individual, carefully shot photos with a Nikon 14-24 2.8, or Nikon 20mm 1.4, plus appropriate filters. Thank you for any relevant feedback you are willing to share.

A: Yes, it will fit with the BH55 without any additional parts.

Q: 4. Will this Ball Head mount to a Manfrotto Tripod?

A: This ball head will mount to any standard 3/8" mounting screw, which is nearly all Manfrotto tripods with a removable head.

Q: 5. Does this truly pan 360 degrees or is panning achieved only by movement of the ball?

A: The BH-25 will pan by the movement of the ball head. The BH-30 will have a seperate panning lever. See: https://bhpho.to/2yDP42r.

Q: 6. Will this ballhead hold nikon d800 plus 80-400 mm lens?

A: The combined weight of the Nikon D800 DSLR camera and the Nikon is 5.43 lbs. As such, the would work to support your camera/lens setup. While it is personal preference, as a safety precaution, I typically like recommending tripod heads with a maximum load capacity that is 3x higher than the combined camera/lens setup weight. As such, my personal recommendation would usually be for the Really Right Stuff BH-40 Ball Head with B2-mAS Mini Clamp, B&H # REBH40PRO, or if you needed a head with a smaller base diameter, the Really Right Stuff BH-30 Ball Head with Mini Screw-Knob Clamp, B&H # REBH30PRO, is a good option, but yes, the Really Right Stuff BH-25 Ball Head would work for your usage needs.

Q: 7. Does this ball head come with a quick release plate?

A: Unfortunately, the BH-55 does not include a quick release plate. A suitable plate to fit most cameras to this head is the Really Right Stuff BP-CS Multi-Camera Conventional Plate, B&H # REBPCSPLATE. https://bhpho.to/33pXg7o

Q: 9. Will this support a Sony a7riii and a 24-70 f4 lens?

A: Yes, but a bigger head with a bit higher load capacity would be a better fit.

Q: 10. The RRS website shows a Full Size Screw Knob option for the BH-30. That option is not shown on the B&H website. Is it an option from B&H?

A: I'm sorry, that is a version that B&H doesn't carry at the moment.
