Fluid Head, Lightweight Fluid Video Head Silky-Smooth Stable Tripod Head Mount Max Load 17.6lbs/8kg, Tripod Head for 360°Pan and -75°to 90 Tilt. BV40 K&F CONCEPT
SKU: KF31.124
Friends, if you’re a photographer, you’ve definitely heard of K&F Concept.. you likely own a few of their filters! Well guys, if you’re looking for a tripod head that’s beyond the typical consumer grade tripod, this is most certainly the one.
Big and burly, this smooth as glass fluid movement video-centric camera head glides from shot to shot. It’s definitely built for serious use and should last you a great while.
As you can see in the pics, I have a seriously heavy DSLR & lens mounted, and the head is mounted to my heaviest duty tripod. My typical photography-centric tripods mounting screws were too small. If you’re a videographer—you already know this.
Form, fit, and function are superb, and as you can see in the last pic, this tripod head locks in rock steady for those long exposure shots.
Five stars—can recommend.

Quality Fluid head. Reminds me of a Manfrotto one I purchased for a LOT more just a few years ago. It does have smooth motion and good pan/tilt motion. Control is limited to more locking down the movement and there isn't any really fine tuning, but I found the default movement to be great and perfect.
Put the fluid head on a spare monopod for a detail BRoll camera, and it works a charm. Super sturdy, and only funky thing is K&F's orange doesn't exactly pair with the red and black on the monopod.
The handle that comes with the fluid head is great. Rubber handle that is easy to grip and easy to lock down, can be expanded to whatever manageable size you want, and has a versatile option of being mounted on either side. There is an arri lock mount hole also for accessories.

The head works as I had hoped, smoothly and securely at a reasonable price.

This tripod video head is equipped with a telescopic arm and a lockable Arcaswiss type plate.
The head is attached via a large classic thread to the plate of a tripod.
The fluidity of the horizontal rotation is firm but in line with expectations for smooth and progressive panoramas.
A bubble level helps with the correct horizontal positioning.
The vertical and pivoting fluidity is also consistent.
However, the upholstery is a bit fragile to scratches.
A nice and effective video head.

At $80 the K&F Concept V40 fluid head performs really well. It's smooth along both axis, and the telescoping arm is solid (many of these arms have wiggly at the locking joint). I really like the snap-in quick release system as well. There's a moderate amount of "self-leveling" that the head does, easing back to the horizontal position if there's not too much weight. On a day to day basis, there's little performance difference between the V40 and a head that costs twice as much. It's easy to use, doesn't weigh a ton, and offers good value. It is missing some abilities that much more expensive heads have, such as the ability to adjust the torque more accurately, and to stop and start your movements more smoothly. I purchased this to replace a fluid head that had gone bad on a secondary tripod, and it's great for that purpose. Keep in mind that it doesn't come with the bowl stem that connects it to your tripod legs.

This K&F Concept BV40 fluid head is impressively made and performs beautifully. It’s solid, stable, and delivers smooth, controlled motion for both panning and tilting, making it ideal for video work or heavier camera setups.
What stands out
Silky-smooth movement: The fluid mechanism provides steady, professional-grade motion for precise panning and tilting.
Excellent build quality: Made with sturdy materials and precise engineering that inspire confidence.
Thoughtful use of plastics: Some components are composite rather than metal, but this helps keep the overall weight manageable without sacrificing durability or performance.
Strong load capacity: Easily supports up to 17.6 lbs (8 kg), suitable for full-frame cameras with telephoto lenses.
Full range of motion: Offers 360° pan and -75° to +90° tilt range for versatile shooting angles.
Final thoughts
This is a well-designed, professional-quality fluid head that balances strength, smooth operation, and portability exceptionally well. A great choice for anyone wanting reliable, stable motion control without excessive bulk or cost.

This tripod head should only be used for panoramas so that the shots are a bit more precise.
Unfortunately, it wasn't until I unpacked it that it was only suitable for 3/8 stands.
Perhaps this should have been mentioned clearly.
As a result, there has been no test with a stand yet, but I took a close look at the product and tried it out a bit before the new stand arrived.
As soon as I unpacked and tackled the tripod head, I was really surprised because I did not expect such massive and high-quality production.
I expected good quality but not such premium quality.
The quality in particular clearly overwhelmed me.
This is really a solid piece of metal without a cavity, the K&F logo particularly beautifully stands out.
Everything is very nice to touch and nothing wobbles, you really have something in your hand here.
The angle adjustment is very smooth, there can be no jerky movements at all.
I am already looking forward to being able to install the tripod head soon and putting it to the test properly.
I am delighted and absolutely convinced. Great quality product!

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!

This is yet another quality product from K&F Concept, currently listed on Amazon at £79.99. The overall design and build quality live up to the brand’s reputation, making this a solid option for photographers and videographers looking for a reliable fluid head.
The mount is designed to fit tripods with a 3/8-inch screw mount. Unfortunately, an adapter to convert from the more common 1/4-inch thread to 3/8-inch is not included in the package. This omission is a little disappointing and is the main reason for my one-star deduction, as it means some users may need to purchase an additional part before they can use the fluid head.
That aside, the performance of the unit is excellent. The fluid head is well-engineered, offering smooth, controlled, and well-balanced panning, which makes it particularly effective for video work or tracking subjects in motion. Movements feel steady and precise, without the stickiness or uneven drag that can sometimes be an issue with lower-quality heads.
The inclusion of a quick-release plate is another practical benefit. It allows for fast, secure camera attachment and removal, meaning you can switch between handheld and tripod use quickly and confidently without compromising stability.
Overall, aside from the missing adapter, this is a very capable and well-built piece of kit that represents good value for money at its current price.
