I have anA7rii but couldn't get it to work with gaffer tape. Ordered the light dims, hoping those work.

Opaque gaffer tape ? Heck, it's simpler 

to just go into the menu and shut off the 

auto-sensing, assigning either always 

EVF or always rear monitor. With gaffer 

tape thaz the same  result you will get,

depending whether you blind the LED 

or the sensor [or both] :-) To keep some 

degree of automatic switching you need 

to dim ... but not totally blind ... the auto 

switching device. IOW you desensitize 

it partially, but not fully disable it.

The auto EVF / LCD switching on my A7ii is unusable out of the box. The LCD switches off every time I try to use my camera at waist level.

I saw no change with the last firmware (4.00), so I decided to google the problem and I found this interesting thread.

Before ordering Lightdims, I decided to try a piece of a laser printer label. Covering the sensor for about 1.5 mm at left or at right gives decent results. Now the LCD switches off when the camera is at about 10 cm / 4 in from my waist. I don't use the camera much closer at waist level.

It's a shame that Sony doesn't provide a user-friendly solution for this shortcoming. A manual EVF / LCD switch on a custom key would be great.

Update: I had to service my A7ii under warranty for a shutter problem and since the repair I don't need to mask the sensor anymore to get a usable LCD/EVF auto-switching. It switches to EVF at approximately 10-12 cm from my body, like before with the partial mask. The a6000 I bought since my previous post shows approximately the same behaviour.

The parts replaced include the main board (SY-1049), a mount (DL-1003) and the shutter unit (AFE-3360).

But I still think the best solution would be a toggle switch on a custom key.

Peculiar that it went away after repairs. This is one of the most persistent snags in E-Mount cameras.
