I just received a Konova K2 Slider (more info: tinyurl.com/bkg9lqm), so I grabbed my DLSR and headed down the Lower Rogue River Trail in Southern Oregon to give it a go. I have to say that I am very impressed with the slider. It is very smooth, attaches to a single tripod (or two if you need more stability) and was easy to hike with. The price tag is about as low as you are going to find for a slider with bearings, but it bring a lot of value to my videography. This slider allows me to get shots that I could have never pulled off without it. I still need a bit of practice with the slider, but I am pleased with the results of my first outing.
