The analogue again wins the battle to digital: photographing the solar eclipse with your digital camera can ruin it

With the solar eclipse just around the corner, thousands of photographers prepare their equipment to try to capture the best snapshot of the moment: a long-range telephoto lens, a low ISO and patience to get the shutter release pressed in just the right moment.

A priori seems simple and does not differ from photographing a sporting spectacle or simply taking a picture of the full moon, except for a small - though vital - detail: the radiation of the Sun during a solar eclipse is much greater than at other times and that , Coupled with the magnifying effect of the rays through the glass lens of the camera lens, can produce a powerful ray that destroys the sensor of our camera for life, if the proper filter is not used.

To check, the guys at Every Photo Store, an Iowa store, decided to check what happens if they took a solar photo with an unprotected camera: they used an old Canon Digital Rebel XT (also sold under the model 350D) and they put a Canon lens 400mm f2.8 IS LL, focused the sun, and observed what happened:

The result is obvious: the upa effect of the lenses, added to the effect also multiplier of the mirror of the camera, make the second appear smoke in the sensor, and that just a few minutes later, the sensor is practically ruined by Life, and therefore, that of the camera.

We made this video to warn people of the danger that has to use the camera pointing towards the sun without sunscreen. Both the trigger and the sensor were calcined in a matter of minutes.

This is just another battle won by analogue to digital photography: digital photography, always having the same sensor, causes any damage to it to affect the camera completely for life, in this case, leaving it unused at the moment . The same experiment, practiced with an analog camera, would have been solved with only one of the frames of the spool burned, leaving the remainder of the roll usable and, in the worst case, having to change the spool burned by another intact.
