I needed a slider for a small production that I was doing so I decided to look for one online...and there were a ton of choices. There were different types from different manufacturers. There's basically 2 types...the friction ones and the bearing ones.
Frictions camera sliders usually just use friction to move the camera plate from one side of the slider to the other. They have lubricated rails to make the camera plate slide easily. They are usually cheaper but the cheaper brands don't have the smoothest action. In video where every movement of the camera counts, this smoothness of motion has to be put into consideration to produce professional looking videos. So I was thinking friction based camera sliders are good for the value but I'd rather pay a bit more to get the smoothness that I want.
Bearing camera sliders use bearings to produce smooth, flawless motion from side to side. The camera plate usually just glides giving it an almost perfect motion. I looked for the best value in bearing camera sliders and I found the Varavon Slide Cam lite series. I decided to purchase one.
I purchased the Varavon Slide Cam Lite 800 which is the 32" version of the slider. The 24" version might be too short for me so I decided to get the next longer one. Varavon is a popular company that produces video equipment. From rigs to jibs and everything in between. I've read that the Varavon sliders have very good quality so I decided to just get one.
The slider came in a few days later and I was pretty happy about the package. The box included a bag for the slide, the slide itself with the adjustable legs, a lubricating device for the slide, a set of allen wrenches for the tension adjustment, and it came with a free focus adjuster for lenses.
The construction of the slide is very high quality. The screws, the mounts seem like they are machined to very strict tolerances. Everything just fits perfectly. It feels really sturdy too, I wouldn't try it but it seems like it can take the abuse of being carried around in the set or outdoors.
The slider action is VEEEERY smooth. This is why I never regretted spending a bit more dollars in getting this instead of a cheaper slider. The camera mount is very light to move around...although you can adjust the tension using the allen screws at the bottom of the camera mount. You can also tighten the stopper on the side of the camera mount to stabilize the mount while you attach a camera or a tripod head to it.
The bottom of the slider has 1/4 and 3/8 sized screw holes for tripod head plates so you can mount it either way. IT also has screw mounts on both sides for mounting vertically into a tripod, this also allows you to mount both sides on 2 separate tripods for more stability. I just purchased a heavy duty fluid head so I can just mount it from the center using a heavy duty tripod...remember you need a heavy duty tripod and head for you to mount it in the center...otherwise the head wouldn't be able to support the slide and move when the camera is on either one of the sides.
I have been using my Varavon Slide Cam Lite 800 for months now and I am pretty much very happy with it. This summer I am taking it to a few location shots so I can make the most out of it.
