In addition to bumpers and sleeves already mentioned I do use reduction and macro rings, I find them very convenient when shooting super macro subjects.
I am very happy with my Kraken Hydra 1500+ WSR. It features both flood and spot mode and the battery has a built in USB-C port so you do not need a battery charger. I usually change batteries between dives but Kraken claim a burn time of 85 minutes at 100% in flood mode.
Hi all. I am Pietro from Italy. I have been diving for more than 20 years and int the last few years I discovered the Philippines which has become my favorite diving destination. No need to say I am very much into macro-photography. I am very happy with the current M 4/3 setup, an OM-1 in a Nauticam housing coupled with a 90 and 45mm macro lenses.
