Very well built slider and capable of carrying my GH5 fully loaded with cage/sound module and heavy lens configuration. However I still can’t achieve a useable smooth slide across the 40cm range. I can maybe get half of the range smooth. It seems that when the arm crosses over itself I get a different friction. I’ve experimented with the friction control and different weight loading but to no avail. It’s a very expensive piece of kit especially when it doesn’t do what it should. Dave

Quick an easy to use, smith movement, with heavy camera expect some vertical shift and use big tripod! Limited tripod use possible (bit wobbly) when wing ist locked.
