I have the T3i and have been waiting around for something new to come out that is actually worth the upgrade. The 6D looks like it is the answer, I am preparing to get this camera in January, after the December release. With my T3i I've been using the Sigma 17-70 f/2.8-4 OS lense, which was a perfect zoom range for me.
With a crop body I assume the 17mm would be extremely wide angle?
what is a lense that gives me similar zoom range on the crop body?
I'd preferably want a lense with a lower aperature like a set f/2.8.
I was thinking about Sigma 24-70 f/2.8
Canon lenses are a bit pricey for me at the moment to justify paying those prices.
Canon 24-105 f/4 seems nice but aperature is not low enough as I was hoping.
I also shoot video so a lower aperature is pretty important.
I had a Canon 17-85 f/4 before and the F/4 aperature was not that great in low light in night.
