So I am buying what you guys are selling. I have recklessly ignored this recommendation to not shoot into the sun.
And you did well! Very nice image.
I know it sounds quite mundane but... Which lens, please? It seems very resistant to ghosting.
Why do all the manufacturers tell you not to? Is it because they are afraid you are going to fry your eyeball with a telephoto lens or something?
Frying your eyes through a ground glass seems much less probable to me than simply while staring at the sun with naked eyes, as the visual pain in the latter situation may tell you (once it's a tad too late) ; the ground glass should scatter much if not all of the energy.
Frying the sensor itself would involve a longish exposure, which is not compatible with our sensors' sensitivities : I'd say that the energy level necessary to fill (saturate) a pixel is a few orders of magnitude below the energy level that may fry it.
Frying the shutter seems much more probable, and one may well point that it's the only fact reported hereabove.

For me, the main reason is to avoid complaints about ghosting and flare.
Remember the the EPL2 "red dots" problem? Just ghosting (but way worse than usual, perhaps because it might have been created at the sensor).
