Viewing The Camera’s LCD — LCDVF Digital SLR Viewfinder
The LCDVF offers high quality optics and comes with a lanyard, cleaning cloth and neoprene case.
The LCDVF is available at B&H Photo here in the USA.
The LCDVF also comes with a stick-on frame to which the viewfinder can clip magnetically; this allows steady use for video or shooting in Live View mode without having to hold the viewfinder against the camera’s LCD.
I don’t use the mounting system; I hold the loupe against the LCD while focusing in Live View mode. Shooters using Live View mode for shooting and/or for video will absolutely want to mount the loupe using the supplied frame.
One drawback of the LCDVF is the lack of a diopter adjustment, so it might not be appropriate for users with uncorrected eyesight. However, I found that I could easily see the entire LCD screen on my Nikon or Canon DSLRs while wearing sunglasses, so eyeglass wearers should not have any difficulty.
Compared to Zacuto Z-Finder
The LCDVF is a bit smaller and lighter than the Zacuto Z-Finder, but the Zacuto Z-Finder offers even better optics with 3X magnification, and that 3X magnification is noticeably easier on the eyes than the 2X magnification of the LCDVF.
However, Zacuto has oriented their product line to video, and the mounting solutions can be awkward for still photographers using an L bracket on the camera.
In terms of price, the Zacuto Z-Finder is almost triple the price, so one has a clear decision there.
Compared to Hoodman Hoodloupe Professional
The Hoodman Hoodloupe Professional does offer a diopter control, but offers lower magnification and I can even see the interior of the loupe’s walls— not so great. In short, the LCD is much preferable for me over the Hoodloupe.
16:9 mask version
The LCDVF is the also available with a 16:9 mask (video oriented). This model has slightly higher 220% magnification.
