Canon EOS 7D

Tamron 18-270MM lens
Camera is not fogging up from being outdoors; it's been inside the whole time. Live view finder works fine, but is turned off, I've tried the "adjustment wheel" beside the view finder; nothing changes. No children or food particles, battery is in place otherwise no pictures would be able to be taken.
Camera is not going into the dumpster at this point...

Google came up with a number of responses to your issue. Most mentioned the battery. Is your battery charge getting low?

I would be surprised if the battery is low enough to dim the viewfinder but has enough charge to take good pictures.

Interesting idea. Some types of humidity are very dark, especially if left over from a recent moonless night.


With a cold camera, bringing the viewfinder up to your eye is introducing a warm, moist environment that can be sufficient to cause the viewfinder to fog over. There is nothing exotic about it.

I went to use my camera for Christmas time, and when looking through the view finder, everything is dark and blurry. I've switched lenses, and the result is the same. The photos I take turn out ok, autofocus is working fine. I've tried turning the diopter with no luck. Would this be the focusing screen? Any suggestions is greatly appreciated!


Last month we spent few days in Charleston S.C. and I had the same problem early in the morning with temperatures of low 40s. I have a canon RP and I noticed when I used the P mode on the cool mornings the view finder was very blurry and will not allow the shutter to work, yet when I switch to Auto mode the camera worked fine. Hopping to post some photos from the Angel oak tree in the near future.

This online manual should help. Search for viewfinder to see the tips for this issue.

My Sony A6000 has a light sensor near the viewfinder. If the viewfinder menu setting is on auto if I back away from the viewfinder the sensor sees light and the view is blacked out and the LED monitor comes on.

At the menu you can also totally switch off the viewfinder! and only have access to operate the at the LED!

Turns out you were right but I am very surprised that it needs more battery power to keep the focusing screen on than to take pictures or even to power live view screen.

And since the problem makes it too dark to see, aim the camera toward the sunny sky at noon to adjust it.


Yup. That's why I said good light.

Maybe it is designed to give priority to taking pictures. This is better than a bright screen with no picture taking ability.

My camera has a fine tuning control for focusing what image appears in the view finder. It doesn't adjust the focus of the lens, it affects your own eye's focus through the view finder. Many times I have accidentally nudged that VF focus wheel (it's small, like a wide watch stem). Then everything I see thru the VF looks blurred, until I remember that I need to refocus.

How about if the camera is new can there be a protective film over the VF??

i assume you have the lens cover off and that you pressed the shutter or backbutton focus to get the camera to autofocus?

EVFs eat much more power than the back LCD. Taking pix takes very little power.
