Varavon shows it's latest Loupe EX Solo View Finder on a Canon 60D. The Loupe EX Supporter (metal bracket) was designed to work on swivel LCD cameras such as the GH2, 60D, T3i. Without the Supporter bracket, the new Loupe EX can be mounted on cameras using a metal frame at the tripod mount. The Supporter bracket is not yet available through B&H, but the Loupe EX Solo are already available (click here).
