I can't agree more to the article. I have an EVF on the NEX-7 and find it tolerable for that size of camera, but I see the pixels, the colors are off, the contrast is too high and dynamic range too small, it blinds me at night and can't be seen in bright sunlight with glasses and I hate peaking. And when Sony made it clear that they will never bring an OVF to market again by unveiling the A99, I decided to change brands.
I think that Sony is losing many customers by making that move. Sure, they will win others, but they should have kept the option for their full frame cameras. The A900 OVF is great.
