Fuji xt30: viewfinder question: If I'm doing a long exposure and light thru the viewfinder may be an issue, by changing the mode to LCD only will that solve any viewfinder issues?

I don't understand why light through the viewfinder would have any effect on the ultimate picture (presumably exposure?) When you look at the viewfinder with the Fuji XT30, you are looking at a small version of the LCD on the back of the camera. There is no sensor in the viewfinder and light hitting the viewfinder would have no effect on the exposure sensor in the camera.
Perhaps I misunderstood your question, but as I understand it, there is no "viewfinder issue" with a long exposure.

Perhaps I misunderstood my own question. Researching long exposures in general, I found photographers say, cover up the eyepiece when doing a long exposure. Never occurred to me that mirrorless cameras might not have issues unlike SLR's. Is this correct?

That’s with DSLR’s that have an optical view finder. With mirrorless there’s no way for light to get through.

Great, thanks!

Yet another benefit in the long, long list of mirrorless superiority.

You are corrrect, now.

Information you received earlier was not correct. In most SLRs the raised mirror blocked light from the viewfinder and covering the eyepiece was not necessary. The exceptions were in cases of photography through microscopes or telescopes where the light path was split by a stationary prism, or pellicle, like the Canon Pellix, rather than a moving mirror.

With digital cameras the sensor area is dark. With digital SLRs the mirror covers any possible light from an optical viewfinder. With mirrorless cameras there are simply one, two, or more screens displaying the image, and only displaying it. Nothing is fed back to the sensor. electronic

Light will still come through the viewfinder using only he LCD. So, during long exposures make sure the shutter on your viewfinder is closed, or if you don't have a viewfinder shutter, put something over it to prevent light from coming through your viewfinder.
Good luck and keep on shooting until the end.

Wait a minute, I thought we established that mirrorless cameras were not effected by light entering the viewfinder. What gives?

There is no path for light getting through an EVF to the sensor.

I think that is the correct bottom line.

I think he didn’t realize you were shooting mirrorless.
