Условие

Two weeks ago, in the morning of November 14, 2012, a Total Solar Eclipse was observed in the North-East Australia. The photo (the whole size displayed) was taken by a Canon SX50 HS camera, which has $3000\times4000$ pixels CCD, and the distance between the centres of the adjacent pixels is $1.54\ \mathrm{\mu m}$ ($=1.54\cdot10^{-6}\ \mathrm{m}$). Calculate the focal distance of the camera’s objective used to get the image.
