Summary: Very good but overpriced. I regret that Olympus has dispended with having a built-in viewfinder, which makes life so much easier in bright weather. The touch-screen is clever, but doesn't work in bright sunlight.
Summary: Much the best viewfinder I have ever used: clear, bright and sharp. It is a shame that this technology is not incorporated into the camera in place of the rear screen which is of little practical value on a bright day!
Summary: This piece of equipment was delivered promptly, and works exactly as it's supposed to on top of my E-P2 camera. The images you see are clear and bright, and are delivered prompt to the viewfinder by the camera.
Summary: Why do Olympus and other camera manufacturers not put viewfinders on their cameras as standard? This is great, especially in sunshine. The camera now feels like the SLR substitute I thought I had bought.
Summary: This EVF is the same as the one Leica will sell you at double the price for their X2 and M240 cameras. EVF technology is changing rapidly so it makes sense not to invest heavily. This one works well, adjustable dioptre, tilting eyepiece and it just slides into the camera hot shoe. Recommended.
Summary: I waited a long while before buying this as it is so expensive and I was hoping the price would come down (it didn't). I have it on an Olympus E-PL3 and have to say that having bought it it does do a good job. People have enthused over the image quality of the viewfinder.
