I was wondering If I should really buy a flash. When I think about it there is a couple times when I would really need one especially when shooting school activities. This is the flash I would be getting and its $350 (price of a new lense) http://www.bhphotovideo.com/bnh/con...005&is=REG&addedTroughType=categoryNavigation It has tons of features along with full swivle and a off camera terminal. I have been doing photography as a hobby hobby for about 1 year now and just got my sony a100. Currently got a sigma 125-400mm 4.5-5.6 and i also have the sony stock lense so I am set on glass for now. The flash would give me a lot of more options especially now cause I want to get into doing some outdoor portraits and some studio.
