Varavon has released a new Multi Finder that is more compatible than their early versions which were very model specific. The new Multi Finder has more adjustments side to side, forward and back, as well as up and down to fit DSLRs from Canon and Nikon. The entire loupe can be removed to leave behind a sunshade, or remove the entire LCD Multi Finder with the quick release baseplate.
