The BH-40 recently underwent a slight
Here's what's changed:
Weight reduced from 13.0z to 11.9 oz
(336g) (an 8.5% reduction).
Main lock knob raised and slightly shortened so
it now clears any platform diameter (previously limited to 2.7”
Main lock knob has 26 available positions
(up from 6)
Main lock mechanism is more robust and
Up to 45% stronger lockup – new load capacity is
still 18lbs but lockup will be easier to achieve. This means that more
force can get you more than 18lbs, but we still only recommend 70-200mm and
occasional 300mm lens limits.
Drop notches have been reduced from 2 to 1, to
improve the lockup stability and smoothness of the ball joint. The single notch
is now centered at the “front” when in the usual ballhead position.
New laser-engraved indicators for both
lock knobs to show which direction is which, tighten or loosen.
Drag set knob has an arrow indicator
showing more drag or less.
40mm diameter ball is hollow in the center to reduce weight.
90-degree drop notch for extreme angle shooting, or achieving portrait
orientation without an L-plate.
Knobs are captive and uniquely shaped, making operation "by feel" very intuitive.
locking lever is spring-loaded; pull out and turn to one of 26 positions to avoid interference with the clamp, camera, etc.
of March 2014 the knob has been raised and slightly shortened, meaning
it now clears any size tripod platform without repositioning.
Drag set control allows repeatable ball tension
settings. Set desired drag with the Main Lock Knob, then tighten the
drag set knob to keep ballhead at that tension.
Panning base is laser-engraved at 2.5 degrees intervals.
All components are either anodized aluminum or stainless steel for years of corrosion-free performance.
Really Right Stuff camera body quick-release plate required; purchase separately.
A note about choosing the BH-40 Pro II ballhead: The clamp that comes installed on this ballhead is our full-size B2-Pro II clamp. This clamp is larger than the clamp that comes installed on the BH-40 Pro ballhead. If the diameter of your tripod platform is larger than the base diameter of the ballhead (2.1"/53mm) you will experience clearance issues when using the drop notch; you will not have full use of the drop notch because the clamp will hit the tripod before reaching 90-degrees. The larger B2-Pro II clamp cannot freely clear wider platforms because the head itself has such a low profile. This is not an issue if you only use L-plates, but we strongly urge you to choose the BH-40 Pro ballhead instead of the BH-40 Pro II ballhead if you use conventional body plates.
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-40 ballhead very conservatively at just 18 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-40 as the ballhead of choice for lenses like 70-200mm/f2.8 zooms and 300mm/f4 primes. Does that mean the BH-40 can't handle a 300mm/f2.8 lens? Of course not! Our BH-40 ballhead is robust enough for occasional use with even a 500mm/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?
