I currently have a T3 (1100d) and while it has served me well I am not overly happy with it. I have a trip to yellowstone next January and am hoping to be able to upgrade bodies by then. 75% of what I shoot is landscapes and if I can find them, the animals that go with the landscapes. What I am not happy with is the ISO performance, since most all animals are easier to find in the early morning late afternoon/evening hours. As soon as I start cranking up the ISO on the T3 the images get unusable real fast.
I also shoot at any airshow I can get to, but that is only 1-3 a year and for personal pleasure.
Otherwise I shoot family and friends in my home studio.
What body would you suggest?
