I was able to test the K&F CONCEPT BV40 Fluid video head a bit and am really pleasantly surprised. The first thing I noticed compared to my previous, significantly larger fluid head is the extremely low weight and the small pack size. This makes the BV40 the ideal companion for traveling, especially when filming with smaller mirrorless cameras.
An absolute highlight for me is the well-thought-out solution that the head natively supports DJI stand plates (such as the RS4 Pro). This allows me to remove my camera from the gimbal in a flash and place it directly on the stand without having to change any plates. This is a huge speed advantage in workflow.
I also really like the handle, which can be extended if necessary. So you can keep it short for transport or extend it to the full length for softer pans.
Of course, you have to be aware that this compact head doesn't offer all the features you would expect from large, heavy video heads. However, the existing functions, such as liquid damping and 360° panoramic capability, are completely sufficient for the vast majority of everyday applications.
However, I have one minor point of criticism that I have to agree with previous speakers: The magnetically held Allen key. The magnet could definitely be stronger. Although the key doesn't fall out by itself when moving forcefully, it comes off when you touch it slightly.
Conclusion: Overall, the price-performance ratio here is perfect for me. You get a silky, sturdy and, above all, extremely portable fluid head, which makes the workflow with gimbals noticeably easier. Clear recommendation!

Cardboard is heavy, it necessarily contains a fluid head made of metal!
K&F is one of the brands that offer a vast catalog of equipment for photographers and video graphers at very fair prices!
I ordered this fluid head and have absolutely no regrets, the quality is there!
The head is 100% metal.
It is equipped with a quick release plate (with a detachable safety) compatible with standard Manfrotto 504 heads (it accepts compatible plates and the plate is compatible with my video heads).
The fluid head is equipped with a retractable arm that can be screwed on both the right and the left.
It is equipped with a 3/8" screw thread to attach it to the tripod or monopod of your choice!
I highly recommend this all-metal fluid head for your tripod if you're shooting video, you won't regret it!

I am very impressed with this tripod head. I bought this for a tripod at my local church, and the cameraman is very happy with this. It holds a camera well, like the Sony Z150.
