Histogram problems.

My EM-1 has just started playing up in a strange way, it seems that the EVF and Live View histogram is not being adjusted by any change in exposure compensation. If, in aperture priority, I move the exposure compensation to the extreme positive and negative ends it impacts the actual exposure i.e. the capture is close to black or white and the recorded histogram is correct but prior to capture the histogram is not affected by turning the wheel. If I reframe the histogram changes to reflect the new scene but not the compensation adjustment already in place. Have I set something weirdly or is this a fault. Can I do a complete factory reset and if so how? Has any body else experienced this?

Re: Histogram problems.

Just to add I have swapped the dial functions around without any affect.

Re: Histogram problems.

Panic over. Full reset seems to have cured it but lost all my settings😞

Re: Histogram problems.

Glad you've fixed it, Jim, but I've no idea what caused it in the first place.

Re: Histogram problems.

There's something rolling around in the vast space behind my brain cell that there's a viewfinder setting, maybe refresh rate ? , or boost ?, that has been found to cause this.

Re: Histogram problems.

I think it is boost that can cause it, I had a similar problem not long after I got the M! but need boost after for the Big Stopper & Live view.

Re: Histogram problems.

Thanks. I don't remember setting Live Boost but one of the joys and downsides of the EM-1 is the number of options you can change deliberately or accidently😁
