In Topic: Best option to backup and view RAW pictures while travelling?

I bring a new card for each day. I see you do video. My friend brings a portable hard drive for each trip and backs up to that from his laptop.

In Topic: Effect on focus distance of being underwater

11 March 2018 - 09:19 PM

As mentioned in that link, the index of refraction of water is 1.33, vs 1 for air.

Your lens will not be as strong due to this and will thus have longer working distance.

In Topic: Cuba Diving and Tipping Recommendations

Tipped about 15%. I think 10% is fair just about anywhere.

Everything in Cuba seemed more expensive than I had anticipated.

In Topic: How to fix a broken Sea & Sea Fiber cable?

07 January 2018 - 06:41 PM

Thanks Bill for this tip, but I afraid I will damage the plug and then I'll really be "up the creek with no paddle" as they say.
 

 
 
Also thanks to the other Bill, I will definitely get some of these for future emergencies, but as I live in Curacao, getting specialist parts is a real bummer, so for now I have to come up with a temporary solution. 
 

 
So for now I managed to find some plastic tubing which is a really tight fit over the fiber cable. I cut both ends of the fiber with a very sharp cutter, and then cut a small length of the tubing put a small incision in both ends and using WD40 as a lubricant pushed both fibers into the tubing until they met, finally I used super glue to seal both ends of the tubing. I've tested on the surface and it seems to work OK, tomorrow I will take it in the water and keep my fingers crossed that it keeps working!
 
Thanks again,

I used duct tape. Worked for about 3 months until I got around to buying a new cable.

In Topic: Panasonic macro 45mm

07 January 2018 - 06:30 PM

The 12-40mm will do 1:3 magnification and the 30mm macros will both do 1:1.  I checked on the 60mm macro and in air with the switch activated the frame width captured is 140mm, too narrow for me, so I leave at full range.   I'm looking at the 30mm because a weedy sea dragon is about 200-250mm long, way too long for the 60mm macro.
 
I have thought about whether you could add a wet wide lens to a 60mm macro port to shoot the  occasional large subject, it's hard to find any specific information online.


Shooting a leafy is not macro photography. I would probably use my 7-14 if I were to go back. Or I would house the 12-35
