samsung has abandoned many camera brands so far.
Rollei, Minolta & Pentax. samsung learned their skills and soon I had to leave them.
samsung does not know that camera (optics) requires a long time as well as technology.
Even if they know, there is not enough enthusiasm to take time and pursue a wonderful goal.
samsung just follow the benefits in front of eyes.
Of course, we must admit that the essence of being a corporation is the pursuit of profit, but Samsung lacks that much.
If someday the samsung owner will have a whim in his mind, he may be doing the camera business again, but that period will never be long.
