Our BH-30 LR ballhead with our B2-Pro II screw-knob quick-release clamp. Choose this ballhead if you only use L-plates and you need a spirit level. This larger clamp limits full use of the drop notch because the clamp may hit the tripod platform before reaching the bottom of the drop notch.   BH-30 Pro features:
A full-size screw-knob clamp to match smaller contours of the BH-30: B2-Pro II clamp.
30mm diameter ball is hollow.
Single drop notch.
Knob and lever are captive and uniquely shaped.
Main locking lever is springloaded; pull out to reposition in 60-degree increments. Lever freely clears tripod platform.
Panning base is laser-engraved at 2.5 degrees intervals, zero to 360-degrees.
All components are either anodized aluminum or stainless steel for years of corrosion-free performance.
Other clamp options: B2-40 LR, B2 AS II, B2-Pro II, or PCL-1.
Really Right Stuff camera body quick-release plate required; purchase separately. Body plates are model specific, not generic. Under the Categories tab on left, select "Camera & L-plates" then drill down to your specific make and model.
Comes packed in its own padded Cordura protective draw-string pouch. Use the pouch to cover and protect the ballhead when mounted to the tripod, for carrying the ballhead in your carry-on luggage when traveling, or when the ballhead & tripod are strapped to a photo backpack.
And a note about load capacity... We rate the load capacity of our BH-30 ballhead very conservatively at just 15 pounds. Why do we do this when competitors' ballheads in this same class are rated for greater load capacities? We feel that a better guide for choosing a ballhead is to consider how well the ballhead operates while it's loaded with gear. For example, we routinely recommend our BH-30 as the compact ballhead of choice for lenses like 70-200mm/f2.8 zooms. Does that mean the BH-30 can't handle a 300mm/f2.8 lens? Of course not! Our BH-30 ballhead is robust enough for occasional use with even a 400mm/f4 lens. But if you primarily use a 300mm/f2.8 lens (and bigger) for your tripod work, we guarantee you'll be happier with our BH-55 full-size ballhead. Bigger loads simply handle better on a bigger ball, period. So when you're trying to decide which ballhead is going to be best for you, consider that load capacity is only one of many features to consider. Any questions?
