Shooting with my T3i I'm satisified with the quality is produces, only thing holding me back is my lens. I can switch over to the T5i for the extra bit of features it has + it being new, and get a couple or few nice lenses and I'd be happy.
With the 6D there is only one lens that is suiteable for my liking. With Image Stabilization, constant aperature of F/2.8, with a bit of zoom.. that is the Tamrom 24-70. With this lens + body combo I'm already looking at about $3k. Also keeping in mind I do shoot videos so the IS is helpful.
For day time shooting a nice lens + T5i I know will get what I want. The only thing is lower light.
The only reason I'd really be buying the 6D for is because of the better low light ISO performance. Which is still a pretty big reason but just not sure if it's worth it. I can always get a lens with a wider aperature to compensate for the not as good ISO performance on T5i = shooting in lower ISO. whenever shooting in lower light.
Looking for some thoughts on this.
90% of my shooting is planned so I can always adjust, I'm just not sure how much better the 6D ISO performance is. If it is amazing, then I will have to consider the 6D in that case.. but then it limits me to 1 lens with my budget (for the time being), which is still ok with me. I also have a spare 50mm II
