    Because you said you did not know to this statement:

    "pointing directly at the sun is fine,

    but pointing directly at the sun is fine and looking at the viewfinder for long is not fine."

    So logically, since everyone already told you the former is fine, you were referring to the latter, namely " looking at the viewfinder for long is not fine". So my question was to you - would it not be logical not to stare though the viewfinder when your camera is pointing at the sun for too long too?

    i 'burnt' a 550D sensor before. but that was after shooting 3hours+ of videos continuosly ( i switched the overheating protection off).

    so your exposure has to be abt 3hrs

    Keep the sun out of the frame

    Keep the sun well out of the frame when shooting backlit subjects.
    Sunlight focused into the camera when the sun is in or close to the frame
    could cause a fire.

    My post was in relation to my 1st post. Say I was doing trial n error. Exposing for 20sec without a filter = grossly over exposed picture + possible burnt sensor? Same settings but with 10stop filter = over/under/perfectly exposed picture but no sensor burn.

    Apologies for not phrasing my qn properly.

    Other than that, no sensor damage from long exposure...

    If you bothered to read through all their posts, it would seem that only jace and iguana posted something in reference to "directly at the sun" While jace was unsure of his statement, iguana made a passing remark as to his lens being damaged with no harm to his sensor. that is post number "1'
    catchlights then kindly said that pointing the sensor directly at the sun would not be harmful. this would make his post number "2" i thus thanked him as this is a direct response to my statement.

    how is this everyone? "telling me" ?
    nitpicking on grammar and phrasing aside, it is of course not logical to stare through the viewfinder.

    Nope. That's just the usual statement by people who realized their oh-so-important issue was actually already discussed to death and is covered in their.manual, which they obviously failed to read.

    I shot many time lapse of sunrise sunset,
    time lapse , as in a few hundreds frames in one sequence, noting happen to my camera, btw my camera are check regular by Nikon Service Center, they didn't find anything unusual to my camera.


    anyway, this photographer should worry more about his eye sight than his camera from the way he shoots.

    Someone @ timescapes forum shot a video of a trance festival with laser lights and somehow got his d7000 sensor damaged.

    But that said I am not shying away doing long exposures under much less bizarre situations..

    There will be no damage either way. You will just get a really nice white picture.

    and they are totally worthless if the photographer is blind, or over concern about damaging them, or don't have any time to use them.
