My Nikon D90 is a valued gift and thus makes it not replaceable whether used or damaged.
I share with you the website below by blind photographers.

I think you might have a problem if you do something like a 4 hour exposure into the sun without using any ND filters.. The ND filters will cut out the light anyways.
You should probably care more about lasers:
Laser safety for cameras - International Laser Display Association
how many people taking up photography and quit within a year or two?
how many people keep shooting and shooting and shooting for 10-20 years?
how many people still pursuit photography despite of physical handicap?
so what is photography mean to you?
I don't know if my query is relevant in this thread.
This question popped up as I was reading this thread. I'm the minority who uses sony slts. Unlike DSLRs, they use their main sensor to capture the light and display a liveview. Likewise with mirrorless cameras.
Do they stand a higher chance of 'sensor burn'? Since the sensor is exposed to the sunlight all the time?
Actually I don't think sensor will get burnt that easily. However, at very long exposure, sensor will probably get heated up... and that will cause noise to occur...
Now, if you have light conditions that require an exposure of 5 minutes (e.g. night scene or by using ND filters) it means that after 5 minutes your sensor has collected the same amount of light (rays and photons) as compared to a picture on a bright sunny day in Auto Mode. Where should the sensor burning come from?
I was wondering if using a longer focal length (like supertelephoto) to fill up the entire frame with only the sun will cause the sensor the burn up. (although this doesn't make sense composition wise, but just for discussion sake)
It's akin to using a magnifying glass and concentrating all the energy on 1 spot. A simple magnifying glass can cause dry leaves to start burning in seconds, so would our lens do something similar? Especially longer lens.
As for exposure time and amount, mirrorless cameras have their sensors exposed to light all the time. Thus I think the time for proper exposure would not be relevant for mirrorless cameras. DSLRs have the light reflected away when not exposing, so they should not encounter sensor burn issues as easily.
If you are so worried about the sensor burning, everytime you point your camera in the direction of the sun, just cap it.
If you are not, just shoot.
I know I care more about having good light, doesn't matter whether the sun is in the picture or not. I do have sentimental feelings for my camera but at the end of the day it is the photographs that matter more than anything else.
Loads of people have shot into the sun since long time ago, you don't hear much about people complaining that their film caught fire, today you don't see many people reporting on sensor burn. Yes there are incidents but looking at the greater picture I'd say it's fair to conclude that the occurence is low and consequently the risk is low as well.
Let's get back to photography, this esoteric talk leads nowhere.
You can't even look into the viewfinder unless you want to get blind. So had to use live-view to compose the shot, the lens steps down to get the proper exposure for live-view. Actual exposure was ISO100 1/8000th f/16, just to get an idea. So the amount of light that actually reaches the sensor isn't that much as what your eyes perceive.
To keep the discussion going, aren't CMOS/CCD sensors inherently more reflective than film?
Perhaps I should not have responded to you at the beginning when you quoted me.
I see no point and is too much effort to reply to you when you question about whether is it still about reality and in this universe.
I continue to believe that when I shine a UV torchlight through a lens onto a $2 bill that the UV security features still shows up and that a plastic like safety goggles blocks more UV than a B+W filter.
I continue to believe that it is possible for the scenario in the camera's user guide. for the very FACT that it is possible to start a fire using a magnifying glass.
