I recently got into photography (a few months), I feel I am progressing quickly and have a firm grasp on camera settings, though I am working on experience.
I am getting close, but not quite able yet, to take pictures as good as my phone camera does - Pixel 2 (My phone takes pics in mid to low light of moving animals at ~50 iso, IDK if I can compete with that!)
My main purpose is to be able to take pictures of wildlife (mostly mammals) from a distance. After much reading I am worried that on my trip to Costa Rica, where I keep reading that the jungle canopy leads to necessarily high ISO levels, that my camera will not keep up.
I am currently using an inherited Canon T3i and am thinking of upgrading to a T7i for that reason (higher ISO tolerances), as well as the 16% increased resolution.
I plan on mostly using a 55-250 IS STM lens as well as my "nifty 50". I have a flash with a diffuser and a tripod. I read that spending the money on a lens is likely a better choice, but am wondering due to the low light conditions that in this case I would be better off upgrading the body. I am not too interested in the extra functions etc, just want good pictures that I am not going to regret.
Thanks for the advice!
