Merlin
 

I own a Merlin and it is a nice piece of equipment. It works really well.
However, the perfect balance of the rig is absolutley vital and it is not that easy.
Also in order to make the most of it, you will really need to practice with it before going on a shoot, because it takes some time to get used to the rig. Lastly start doing some push-ups because unless you are using a really small camera, it is a major work out on your arm. I might be a whimp but after 10 minutes or so with a Z1U on it, I'm worn out.

Matthew,

I don't doubt that it is a handfull to hold for any length of time.
I have worked in feature films for many years and the steadicam operators have a very hard time if the shots go for alot of takes.
A very underrated job.

thanks,

David
