In Topic: Canon g16 settings

20 August 2015 - 06:36 AM

Take a look here: http://www.uwphotogr...rwater-settingsThat is mostly what I did with the G15.

 

I set up C1 for macro (including the lens zoom that gave the best magnification with some reasonable working distance, 13 cm or so as I recall). I setup up C2 for action wide-angle. 1/125s, fast f/stop, widest zoom setting, and auto-ISO

 

Do you have an external strobe? That would definitely change what you use for Macro.


In Topic: New Olympus lenses 7-14 and 8mm vs 9-18

Ps: a quick hack to improve corner sharpness in the 9-18 is to mount a +2 dry diopter, preferably achromatic, on the lens inside the dome. Canon makes one, and the price isn't too bad.

Typos are a feature, not a bug

Nice tip. Does this work inside the Zen dome or is there not enough room? 


In Topic: Olympus 60mm First time shooting - tips?

Can someone comment on the differences of shooting this lens behind the Zen dome and behind the flat port? I have both and the flat port is equipped with the Reefnet +5. But I have not shot the 60mm lens other than in a pool.

 

I would assume that since the dome increases the FOV of a wide angle by 1.33x, that it would do the same for the macro, reducing the maximum magnification. Am I wrong?

Well, like many apparently, I had an issue where I got the original o-ring outside of the channel and sliced it as I turned it down. I noticed right when I got in the water. AFTER that, I got this kit. I've not had a chance to test the 2nd o-ring, fortunately. 

 

I will say that it makes getting the battery cap on more difficult. It probably takes one turn out of the tightening, but it takes a lot more elbow grease to get the cap on and off because the compression of the o-ring is pushing the threads together.
