Midday sun and sensor A7ii

Hi every one .

Does anyone knows the dangers for the sensor by shooting in a sunny day at midday till the afternoon having in some shots the sun in the frame?

I do some times have the sun in the frame ,and i use legacy lenses

Here in Athens the sun is quite bright and hot in the summer.

I did read in some forums for burned or fried sensors by having the sun in the frame.

I just wanted to know how easy is to burn the sensor in these conditions? How long the sensor has to facing the direct sun?

how can i see if it s burned or any other kind of damage have occur ?

Thank you all

Hi @wil-1275 and welcome to the Community :slight_smile:

 

The amount of time needed to cause damage would depend on the aperture

and focal length of the lens you're using.

Theoretically damage would appear as dark areas in images or dead pixels, 

but it isn't a common problem.

 

Hope this helps :slight_smile:

Thank you  Jumpsuit

I use a 50mm and no more a aperture to f/11.

As i can see there ar no dead pixel or dark areas. How can i check it to be sure?

In that case what is the procedure to fix it?

In forums the showed pictures of sensors with white spots or melted parts. 

 

Thanx again

Hi again :slight_smile:

 

If a sensor suffers a burn then it requires replacing.

Shooting a narrow aperture lessens the risk in general but does focus more light waves at the sensor,

rather than in front or behind the focal plane.

The camera has a built in thermometer to try and protect it,

but if a small area of the sensor became hot then it's harder to detect.

 

It sounds as if your sensor is ok so far though :slight_smile:

I checked the sensor and everything seems fine. 

It looks like it should be , no white spots or anyting matte spots or anything unusual.

So i hope the sensor is ok

Didn t know about the thermometer , thats cool.
