Ok great, move along now. I'm not sure why you're still here, you tried out some EVFs in their default settings in a store and didn't like them and complaining on the internet about it. It's the equivalent of someone going into a DLSR thread to complain that the OVF doesn't simulate exposure.I would like the EVF image to look the way the scene looks to my eye, because that's how I'm going to process the raw data in almost all cases.
For anyone else..... here's the useful information, if you're skeptical about EVF's make sure you're using the right settings that are a priority to you. That's the great thing about technology, you have more choices. If it's not good enough, don't buy it, it's not for you. You can replicate OVF, use exposure simulation, or a combination of them. Then there's myriad of other options not possible with an OVF.
If you don't like an EVF stay with your DSLR, they'll be around longer than you'll probably be alive and be fully capable of capturing great pictures.
