I am new to the NEX world or should i say mirrorless cameras and i recently bought a NEX6 kit, i really love it and i need to learn more about them. i want to expand my lenses but i don't know which to get- Sony lens are expensive and limited, so ai joined this forum to get some help. I do not know anything about other lenses and/or how they attach to the cam- if they need adapter and what adapter would it be. So my main focus or subject is my daughters, so i would really need a very fast lens, i wanna be able to have minimum focus distance of atleast a foot. Can you please recommend what you use and maybe where i can get them cheap? Thank you much for your responses.
