Hello,
I would like to purchase the 70-200mm for my 7D. I am using this for videography mostly but I am on a serious budget. Of course, the best bang for my buck would be to find the lowest price, most recent manufactured, used f4 copy. These usually go for around $500. The only thing is, $500 is alot to spend and I dont want to wish I had a 2.8. Though I cant afford it. Any suggestions? Anyone else use the 70-200 f4 for videography? I also feel as though I would only be able to use this lens outside or in a well-lit area.... The 7D doesnt do well with low light like the 5D from what I have researched. And I follow a strict rule of never using more than 800 ISO for video....
Thanks in advance!
