Yes but the EX3 has that great viewfinder (which really makes it feel like a real movie camera) and you can brace it against your shoulder. The EX1 will destroy your wrist muscles or you back muscles if you wear one of these Indian bogus EX1 rigs. The EX1 also looks like a real professional camera on a professional set. Isn't that worth the extra 2000 Euros?
I think you meant the EX3 looks more pro.........
That said...... Only a true insecure amateur would be concerned about the "Size" of his camera and what other people think!
I once did a print ad for a major Ad Agency for a Major Hotel chain. Total cost of production was just over a hundred grand.
I shot it on a $9.00 plastic camera called a Holga. I had 10 of them cause they all shoot a little different. There on my $2000.00 Gitzo tripod sat a nine dollar plastic camera.
If your concerned about what your clients think about your camera.... Your in big trouble cause your thinking about the wrong thing !!!
