Thank you for viewing! Manfrotto Ball Camera Leveler 438 This leveling base, set between a video head and tripod, was a great companion that allowed me to take beautiful photos of the Japanese paradise flycatcher. The reliability of a top-tier manufacturer was impressive. It holds steady even with a single-focus 600mm lens and a full-frame SLR camera. There's a YouTube video that also praises its stability, so I recommend watching it to understand the difference. I was able to focus on shooting with peace of mind. It's installed between a tripod and head that don't have a built-in leveling mechanism, making it easy and quick to level. I've used half-balls before, but I found this one faster for leveling. Recommended for those who don't have a tripod for half-balls. (♡∀♡〃) The operating range is 10°. The condition is as follows: Appearance: No noticeable scratches, but there are some minor scratches and scuffs upon close inspection. Operation: No particular problems. Suitable for head base diameters of 60mm to 65mm. There is no box, instruction manual, or accessories. The set screw for fixing is a flathead screw, not a hex screw. I don't smoke. I don't have any pets. Thank you for your consideration.
