Gives the reach without breaking the bank

I find great peace wandering around the zoo observing the various animals. My 70-200 f2.8 L USM II has always served me well, but I've always wished for a bit more reach with my lense without breaking the bank for a larger telephoto of good quality, similar to the canon. Thankfully it is one of the supported lenses for the extender. Paired with my Canon R5, when I got to Big Cat Falls and saw the male was up and moving around. No cropping was necessary other than adjust to 8x10, because I preferred the formatting for the shot. Without the extender I would have needed to crop in for a similar shot. It definitely adds a bit more weight, free handing it waiting for the perfect moment can get a little challenging. As long as you know telephoto is where you plan on spending most of the time shooting, it was excellent.
