I went to see my mom last Saturday - brought the Steadicam Merlin that I'm still learning to use. There's less pendulum effect in this footage - maybe because I'm walking around slower than in my forest footage: vimeo.com/831855
This was shot in 25p (PAL) TV mode (1/25) and AWB. I think, I need to use a faster shutter speed for moving shots - maybe something like 1/100 instead. I think that would have given me less blurriness.
The Steadicam Merlin is not a toy that instantly makes any footage look like a million dollar production - you need to practice with it for some time before you get to know it well.
If you don't mind the price, I can highly recommend it for any advanced user. By advanced, I mean someone with a good portion of patience and someone who's not expecting it to be perfect right out of the box :)
