I really do like a lot of the images on your website, I had looked at your FB page first. I like the wedding photo that is the banner on the website. Good color, exposure, and emotion in the photo. And the headshot Gerbles linked is very nice.
The 5D II or III are known for excellent low-light performance. I’ve heard the 7D is decent, but it’s not a full-frame body. I also have a T2i and it’s pretty terrible handling high ISO while the 5DII is great. I don’t regularly do weddings, and so I typically use my 70-200 f/2.8 lens for portraits, but I borrowed a 24-70 2.8 for a recent wedding, it’s necessary to have a wide-angle lens especially for those tight church altar shots.
