Best lens for Sony a6400?

[mattshell81]

Anyone have any advice for good which lenses would be best to get tank shots and closeup videos with my Sony a6400? Using the 16-50mm lens that came with mine currently and even straight on I have issues getting good focus on things further back in the tank. Looking for any and all advice so feel free to name budget and pricy options. Just want to hear what other people are using.

For my DSLR i use a 100mm macro and a tripod with a remote to take the picture. The key is just have no flow going on, and play around with the settings on the camera.

I have never had experience with a DSLR before so i taught myself with google.
