Thoroughly enjoyed this. Absolutely gorgeous. Loved one of the edits the most, where the Nudi brings out its gills as also the beginning. Thanks for sharing. I wish i could learn to edit videos :-( :-(
A 100 mm is always a better choice as you get more space between the camera and subject. Also a shallower depth of field helps. Most subjects in Lembeh can be covered by this lens. A diopter is useful for getting some creative images and helps with the really teeny weeny ones. I normally carry one. That said the 100 mm is also good enough to cover most. Worse case a bit of cropping is always a possibility.
Mumbai, back in the early days we used to have Fiat cars with wipers that never really did the job in a heavy downpour. So we used to buy a filter less cigarette called charminar. You just have to take the tobacco and rub it on your windshield. No drops ! Just an even film of water that one could see through. I used this with good success. Even rubbing potatoes works. BUT hey in time i just reverted to plain old spit :-) (on my housing dome port - not the windshield
I have used the SMC and have got some really good images which are tac sharp. The really difficult part is using this with the Nauticam super multiplier added to the SMC. Here are some images that have been taken with both stacked together. I was quite pleased with the bokeh kind of result. BUT NOT easy to use.
I carry the housing(minus ports) and strobes in my laptop haversack. The camera's/lenses/video lights etc are in my lowepro hand carry cabin bag with rollers. The large dome, arms, 60mm and 100mm ports are in my checkin dive bag.
