HEY EVERYBODY... I just got my first camera!!!... I got a Nikon D60 with the standard 18-55 kit lens. I'm poor but love taking pictures and want to expand my equipment list =). What must have lens do you guys use and can't live without. I am thinking maybe a 12-24mm might be my next lens and then a 55-200mm. Of course it probably won't be a nikon lens, more likely tamron , sigma, etc.. whatever I can afford =)... oh yeah..I'm probably into taking portraits and close-up.. thats why I'm choosing a wideangle lens. Any kind of info, brand, other type of lens is greatful while we are on the subject.. what must have filters should i get!!!!!!!
