Who needs LCDVF or Zacuto viewfinder? 2x magnification poorman's viewfinder... I think this solution is better ( abstractedly from price) because it's not as deep as LCDVF and all screen area is visible (contrary Zacuto). And 2x magnification is good enough. Eye piece isn't probably as comfortable as commercial visors, but also good enough and for free. + no glueing of magnetic ring on screen, etc. Video made by RAW Panasonic FZ-18 and slowmotioned Sanyo FH1 (add vignette effect).
