I want to get a lens for coral "colony" pictures, not really for macro, just good quality say 2-6" colonies with good DOF.
I have a Canon 6D that I use and want to get into capturing my tank.
I see that anywhere really around 70-105mm are suggested often here. Namely 24-70mm or the 18-250 sigma. There are some really cheap used options available on B&H that I am completely ignorant on that look too good to be true so what are the potential downsides to say getting an EF 75-300mm f4-5.6 or EF 80-200 f/4.5-5.6 II for $65 over one of these more expensive options? I want to use it for more than the tank also.
Thanks!

I know you might be asking what the heck am I being cheap having a 6D but it was a gift. I mainly shoot astro so all I know really is small focal and very large f/. I feel like there is some sort of trade off that I'm not grasping with some that are ex. ~25-105mm, ~18-200+mm, 70-300mm. Even though they cover the same focal lengths surely you cant get that kind of range without sacrificing something.
