    Hey guys.

    Right now, when I'm on manual mode and I have the settings such that the exposure meter says the exposure is perfect (at 0). If i then go to increase the shutter speed to reduce the exposure, the LCD will show the scene getting darker and darker until the exposure meter hits -3.0, at which point the lcd doesn't get any darker even when the true exposure should be pitch black. Likewise for overexposure. The lcd will only brighting the scene until exposure meter reads +3.0, and then it doesn't get any brighter even when the true exposure is pretty much completely blown out. Is this the norm or is there a way to set the camera so that the lcd/evf reflects the true exposure?

    I came across this when i was trying to dial in exposure settings in manual mode to completely kill the ambient light in order to test something with flash. It's not a huge problem, but just wondering if theres a fix for it. thanks.

    I actually prefer live view boost. I can compose in any light, confirm focus and ensure the elements in the frame are right. I confirm exposure after the picture is taken in the EVF (no chimping).

    my live view boost setting is already at OFF, but still displaying what I described above.

    I haven't notice any difference also if I have the view boost on or off so it makes me wonder if it is a bug. As mentioned above, under or overexposing 3 stops will just get the blinking 3 and it won't get any brighter or darker.

    it's normal (and unrelated to live view boost)

    I rather like it set this way, and it makes sense to me to be able to get some idea of my subject framing even when operating outside these exposure levels.

    for what you are looking at you can just take a couple of test shots and review, even bracket and review, to establish the appropriate settings - I would have thought you would have to take a base refence shot anyway (which becomes your test!). Alternatively you can just use simple calculations based on an initial histogram to establish the settings required to send any scene all the way off the right, or left.

    IMO a slightly better implementation would retain the VF/screen as is but permit the histogram to fully reflect the actual settings ie if you want full black you just dial it down until everything has exited to the left on the histogram. Having said that it doesn't take much to calculate the necessary setting from the histogram at - or + 3 position.

    Yup. That's exactly what I've done. Just do a few test shots and review until i get what I'm after. Like i said, not really a big problem, but was just wondering if there was some settings that I missed out. But it's good to know it's working as intended.

    Thanks all for help!

    I was hoping this wasn't the answer. My Sony A7r and Leica T 701 are able to show a simulated exposure on screen / EVF. This is very very helpful when shooting in dark places where I won't be using flash. The sony even simulates what the exposure is when the flash is turned on. The Olympus reminds me of an more of an optical viewfinder. I do a lot of event photography (band, clubs, bars, performance,...) in which there is no time to take test pictures and the lighting conditions are are often changing. Because of the blazing speed of the Olympus I rather use it, but ultimately I need to accurate exposure.

    Go to settings and find the EVF menu, then go to EVF adjust, then toggle EVF auto luminance to OFF. The default setting is ON. When this feature is toggled on, the camera will try to adjust EVF luminance to match the actual scene, very much like what you would see with an OVF, and in some cases this can lead to exposure being way off from the image shown by the EVF. This had me confused for a while.

    When I had that problem on my EM-10 I had to do a factory reset. It did fix the problem.

    I came here with the exact same problem, I'd like a real WYSIWYG behaviour of EVF/LCD but seems impossible
    in my case I see a little variation on WB, when I look throught the viewfinder, just when I push the button, the camera shows me the preview of the shot just taken and it is a little different than the WB I see in live view
