If you like wildlife photography and especially bird photography then eventually you might need a gimbal on your tripod.
The gimbal makes it easy to follow the bird when it flies by you. It is easy to use, it rotates the way I want it to. I can easily follow fast moving objects with this gimbal.
I can recommend Beike-45. Why?
Because it is great! It is also good value for your money. It only cost 70 US dollars nowadays. Normally similar kind of gimbals cost around 300-450 US dollars. I bought mine in 2015 at Aliexpress from China, then it cost me 78 US dollars. I got it delivered in 3 weeks. So if you are planning to go somewhere for wildlife photography order it in time for it to be delivered before you go on a trip.
I used to always have this Gimbal ready on my tripod when I was going somewhere for bird photography and I knew I would be there for a while. It is not that heavy to carry. It weighs around 1 kilo. On the above picture I have a Canon 70D and Tamron 150-600mm attached to the Gimbal. I dont have to worry that it might tip over, it is very stable and it is easy to rotate.
When you use a gimbal make sure that you have the level meter on your camera. Usually it will look like a red/green line that gives you direction on which way to turn to make the camera straight.
