<p>So I've been using my canon t2i for the past 3 or so years (bought it used) but I'm looking to upgrade to full frame and I was wondering if the Canon 5D is an upgrade in anyway over the t2i or if i should just save up and buy a newer 5D or a 6D. I understand that the 5D is five years older than the t2i but I've heard that the original 5D is usable up to 1600 ISO and I refuse to push my t2i past 800 because at 1600 its completely unusable for what I need. I shoot mostly low light indoor events, and portraits.</p>
<p>Thanks for the advice!</p>
