The F/4L IS II USM lens from canon in the P190port and Reflex Housing from Aquatech is phenomenal to say the least. The canon 5D Mark IV is a total game changer. Life just got amazing! The magic triangle of photography came together perfectly today. Totally loving this lens! I definitely like the zoom gears on the Aquatech more than the CMT housings. I use the reflex housing for the 5D and the Elite II for the 7D.
