I have always wanted to get this lens but the price was never right or I never had enough budget for it. A good buddy sold a K1 + DFA24-70mm F2.8 + Rokinon 14mm F2.8 to a colleague of mine who wanted to get the same camera as me.
She is thoroughly enjoying the camera and I asked it she wanted the Rokinon and if not to sell it to me and I got it from her today. The lens has never been used since the day my buddy bought it from B&H in the USA.
I was surprised of its small size as I thought an ultra wide lens would be big and heavy just like the Irix 15mm F2.4. It is also very light in spite of being made of metal.
I am going to enjoy this lens soon.
