and the rokinons are $500 a piece, its a shame they are that expensive, bill gates will have fun with his $13000 1D-C and his $14000 prime set, which btw i guess now a "set" is only 3 lenses, sure that will do.
Rokinon however, does not offer a 50mm lens... and even if Bill Gates were still the richest man ever I don't see him having fun with an all manual set of lenses, not in this digital age where 64K is not enough!
They (Rokinon/Samyang/Bower) have a 50mm coming first half of 2013. Now all they need to release is a 100mm or 135mm lens (or both) and they will have pretty much all bases covered for the beginner shooter.
Sure they arent these lenses from Canon but they are crisp and clean and a good start compared to using std slr lenses.
