Thank you so much for the feedback!

 

Yeah, I know I will be losing length when I switch to full frame. But I am only shooting sports for a short period of time, and trying to concentrate more on portraiture, and nature. I probably will buy the 2x extender when I switch so it adds to the focal length. I guess that's the added advantage of having a crop sensor compared to FF;I think it's what, 112-480mm for the 70-300mm on an APS-C body? . But, with the lens lineup I have now I want to switch due to what I am doing later on :D

I've considered some of the other L telephotos but they are so heavy in terms of price and weight lol. I would love the 70-200mm f/2.8 L but that is over my budget at the moment!!

Talking with a friend of mine he suggested I take my body to a shop and test them out or rent from borrowlenses. I think I'll go test them out and go from there.
