I have a SteadCamJr. This was made before the flip out screens were invented and before the cameras of today that weigh less then 4 lbs. I don't use the screen on the SCJr but I put batteries in it because it happens to be the right counter balance weight that I need. I can't use my wide angle lense because it is to heavy for the SCJr. (which bums me out). But I would think that the Merlin would be better designed then the Jr. I'm looking forward to getting one and hopefully I can use my wide angle. I don't like that the Merlin doesn't allow itself to be mountable to a tripod. A feature that I like when it is time to chase the bride out the door.
This industry sometimes forgets that there was a time in the not so distant past that the only time you got paid was when you woke up the next morning and went back to work. Earning royalties for something you did 20 years ago is only a recent phenomenon.
