This stabilizer really very suitable for an SLR -in my case a gun 650D-. The finish is impeccable for all parts. The accompanying CD is a very good guide: Chinese and English (read the second file) the video is quite explicit by it même.Une times the setting methodology assimilated excellent stabilization is obtained from (!) unit. It will just re-adjust the balance when changing lenses. Product recommend with excellent price / quality ratio. The only regret lies in -vis- fastening system under the unit which requires redo the settings when disassembly.
