Not sure if you can see the thumbnail in the video, but something about that slider doesn't look quite right. Oh yeah it's upside down! Vimeo member phoSumpro! shows a new way to use the Konova slider. Actually seems like a new way to use any camera slider. By mounting the slider upside down with the carrier Tripod, he's actually sliding the entire rail (not the carrier). I'll let the video explain why this was done, but that's one pretty cool trick. Sorry guys, but don't think this would work on a non Roller Bearing type slider. [Thanks phoSumpro!]
