Towards the end of 2010, it seemed like there would be an explosion of Electronic View finders. In the end only a handful have been popular such as the Cineroid EVF (starting $548), Zacuto EVF (starting $749), and the SmallHD DP4-EVF (starting $599).
Here's a cheaper 3.5" HDMI EVF you will probably be hearing more about from Seetec. The magnifying loupe attaches and detaches similar to the SmallHD DP4, but that's pretty much where all the similarities end. Kicapi Productions has a video demonstrating some of the features [Thanks Kicapi Productions].
So hopefully the video above answers any questions about the EVF as you begin hearing about it from other blogs and forums. It's definitely not as high quality or as full featured as the other brands, but it comes in at about half the price. Kicapi Productions has the Scope 3.5" EVF already available to Malaysian/Asian countries at https://www.kicapi.com.
For other buyers, the Seetec 3.5" HDMI LCD EVF can also be found via eBay (click here)
