Related Questions and Answers

Q: 1. Can this clamp be mounted on another clamp to be used to change the direction of the rail's orientation?

A: Yes, this is possible, but depending on what equipment you plan to mount and the knob size on the other clamp, there could be interference, though many configurations should work.

Q: 2. 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.

Q: 3. Will this be okay to use with an a7Riii and a Fe 24-70mm f4? Seem to be under the 8lbs weight requirement, just not sure how it is in real-world use for traveling.

A: Yes it will be. This head has an 8.8 pound load capacity, the combination of A7RIII and FE 24-70 F/4 lens are well under that load capacity.

Q: 4. 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: 5. will this ballhead hold a niko d800 and 80-400 lens?

A: That lens and camera weigh nearly 6 lbs, which is too close to the load capacity of 8.8 lbs. You can never have too much capacity. This RRS ballhead would be a much better option: https://www.bhphotovideo.com/c/product/1301053-REG/really_right_stuff_bh_30_pro_bh_30_ballhead_with_mini.html

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. Is the Kirk BL-D800 L-Bracket compatible with the Really Right Stuff BH-30 with screw knob? I've already got the kirk plate for my larger Kirk ballhead, but I'm looking for a lighter travel head and I think this one will fit the bill assuming the plate will work with it.

A: Yes.

Q: 8. Has anyone had any experience with the FB-52 ballhead?

A: The majority of Sunwayfoto ball-heads sold by B&H have 4 to 5* reviews. Most of their other products have the same ratings. We feel that you will be satisfied with your purchase of this head.

Q: 9. Can you use the Peak Design Quick release plate on this?

A: Yes, the Really Right Stuff B2-mAS Screw-Knob Clamp with 1/4"-20 Screw (38mm) should be compatible with the Peak Design PL-S-3 Standard Plate (BH #PEPLS3), because the plate uses the same Arca-Type quick-release design.

Q: 10. 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.

[4 x 1.35 x 1.2"] It works on my shoulder rig for mounting my Zoom H5. Costs less that half of the next more expensive one I saw. I’m buying other things from Camvate now. 5

[4 x 1.35 x 1.2"] I replaced all of the T-knobs on my underwater camera rig (all 7 of them), as with a black housing, black arms, black floats, and black clamps with black T-knobs, it wasn't always obvious which way the T-knobs were facing. Adding this Red T-Knob to my black clamps instantly solved the problem, and makes quick adjustments underwater easy and fast, without thinking! The machining and quality of the knobs is superb, and matches the quality of all the other ULCS products. 5

[4 x 1.35 x 1.2"] The ULCS triple ball clamp with cut-outs on both sides is ideal when you want to mount a light and GoPro to a hot shoe, or a Go-Pro or light to the joint between two arms. Having the notches gives you extra flexibility in the angles the arms can reach. In my case, it helped tremendously when using a GoPro with a very wide angle lens, and a focus/video light. I was easily able to move the focus light out of the field of view of the camera. The standard non-cutout triple clamp doesn't work nearly as well for this purpose. The clamps don't seem to have lost any clamping strength by adding the cutouts. Highly recommended! 5

[4 x 1.35 x 1.2"] Easy way to keep track of personal equipment. But i recommend that if you color coordinate your gear to look at the options on the arm and save your self doing it twice. I just wish there was a discount for returning the old t knob 5

[20] this original equipment ultralight ball clamp is great. Works great and was shipped very quickly. 5

[4 x 1.35 x 1.2"] I have black clamps, black arms, black floats, a black housing, black port....you get the idea. Having red colored T-knobs for the clamps makes it easier to grab and adjust the knobs, without having to look to see which side of the arms the knob is on, or to even have to think about it. They are an exact perfect fit and replacement for the OEM ULCS T-knobs. Love them! 5

[4 x 1.35 x 1.2"] I like the weight savings from the original Ikelite clamps. And the choice of colors for the T-knob makes my rig distinctive among the other rigs on the dive boat. 5

Dan	17/06/2024
[4 x 1.35 x 1.2"] Using it to mount a PTZ camera at a strange angle on a desk. Works perfectly. Holds firm. Made very well. Great price. 5

[0.035 lb] Ultralight makes the highest quality arms I've ever used, and this t-knob clamp is no exception. The red finish is super high quality, this will last for years. 5
