E = mc2

If E = mc2 is the energy of a photon, shouldn't wee need the mass of a photon to calculate this? This means photons have a mass, but only when they are moving and producing kinetic energy? But, they have no rest mass?

E=mc^2 is a formula used for matter. Photons do not have a mass, so the equation to calculate their energy is: E=(h*c)/lambda.
