There is major camera companies are well known but accessories have variable choice. GVM is one of company makes accessory for video shooting.
This is slider I purchased for my shooting.
It comes with case. That is one thing good for this accessory.
When you do not have carrying case or protection for accessory. You need to pay extra to get accessory for accessory.
When you open it, it has Styrofoam to protect and fit in it.
It is easy to put it back and take out.
It comes with cables for all the camera available in the market.
You can connect the camera with slider more option to operate.
Head are very stable and sturdy.
I used Red Komodo 6K with built that I have.
It holds everything without problems.
It comes with two batteries and two charger.
Slider takes two battery to operate but you can use with one battery to operate.
It is very nice slider to use it. However, one thing that I dislike was it does not have manual slide. I have to force to use as manual it works but it could be damage on the motors so I won't recommended.
