When Fujifilm previewed the X100 at the 2010 Photokina, the big hype from Fujifilm was the hybrid viewfinder. The customer reaction was mainly to the large sensor and retro controls, though, with the hybrid viewfinder being considered a very nice addition to the retro touch. The press were the ones that got the most excited by the hybrid viewfinder, which was the one "new technology" that seemed different and interesting at the show.
Today, though, Fujifilm is finally getting a bit of news: the X-E1 is going to far outsell the X-Pro1. But it doesn't have that hybrid viewfinder that was all the craze from Photokina 2010 onward, so what gives? Ahhh, you mean people were buying the X cameras for something else than bracketing lines in an optical viewfinder? Doh!
