Q: 1. Will this work with the peak design pro plate?

A: Yes, it will.

Q: 2. Does the screws and adjustable levers with the grips stay firmly affixed to the knob or can they rotate in their own? I have been burned in the past with other ball heads where the rubber grips can loosen over time especially when tightening the ballhead and you meet resistance after getting it tight then the rubber grip starts to move. Do these grips do that?

A: 100% No. Gitzo stay were you put them. All tension control knobs stay where they have been adjusted.

Q: 3. How is this screw know compared to the lever clamp?

A: The screw and the lever are personal preferences, beyond that some users like the lever when they are shooting in cold weather and wearing gloves. The lever is much easier to use with gloves and is also quicker.

Q: 4. 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: 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 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: 7. Sorry Hector, this is really a clarification on my initial question; while I am sure the knobs stay put when they have been adjusted, I am more so referring to the rubber grips, can these slip off or rotate independently of the knobs in case the knob is being tightened tightly. Do/Can the rubber grips slide?

A: The rubber grips on the Gitzo GH3382QD Series 3 Center Ball Head will not slip off or rotate unless they are worn out. The head is covered by a 10 year warranty in case that happens.

Q: 8. 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: 9. Can you buy the screw know clamp separately? If so what is the product name/number?

A: The Screw-Knob Clamp is available for sale separately: https://www.bhphotovideo.com/c/product/1301182-REG/really_right_stuff_b2_mas_screw_knob_style_quick_release_clamp.html
