I finally got a new camera after. I upgraded from a Canon Rebel T5i to a Sony A7RIII. I picked up the Sony 90mm macro lens and just got my Avast Marine Porthole today. I tried out the porthole to take a couple of quick shots in auto. Not the best pictures but not bad for auto camera settings and no post editing. I had to shrink these images way down so they would upload. I can't wait to take some time to really get setup for some macro shots.
