I currently shoot a 40D with a Tamron 17-50 (non vc) and I would like to move to a full frame camera within the next 3 months. I have been checking out the 6D as the first choice because of its great low light performance and price. I mostly shoot nightlife, weddings and models (you can check out my Flickr and my website for examples so you can see what I shoot.)
I also would like to know what lens should I get to replace the Tamron that will be around the same zoom range to go with the full frame 6D. I *was* looking at the Canon 17-40L but I would be losing the f2.8 capabilities and the extra 10mm.
Another reason I was looking closely at the 6D was because of the fact that it can shoot video as well and I would like for my first FF camera to be able to do so.
Is the 6D a good choice as my first move into full frame? And if so, what lenses should I get and again, keeping the Tamron 17-50mm range in mind.
Any and all advice is greatly appreciated. Thanks!
