A bit of perspective -- I still own a large Nikon D70 DLSR with several lenses, SB28 flash,.... I find this camera to be too heavy for use on the boat
and traveling. I don't want to carry around an entire backpack of camera gear
that weighs 20+ lbs. Space is limited on our boat
too. When I was diving, I used to own a Nikonos III with external flash. For diving in S.Cal, I didn't have a lot of use for the Nikonos and I sold it a few years later.
Last season, all of our pictures were taken using our iPhones. They are OK, great for selfies, but not great for taking wildlife or landscape pictures. Easy, convenient, but not great. This season, I'd like a better options for taking pictures, wide angle/zoom, hopefully some underwater shots, and of course the boat shots against the rugged baja
Both the Olympus TG-6 and Nikon Coolpix W300 are similar "travel, waterproof, tough..." cameras. I preferred the configuration of the TG-6 (settings dial, zoom, exposure dial), along with the interchangeable lenses (2x zoom, fisheye). I'm not worried about the 15m (50') depth
rating - I'll be using while snorkeling or hiking. If I drop it in 50+ feet of water, I'm not freediving to get it! The waterproof seals
are similar -- rubber pads on each door, with a double-lock closing mechanism. From what I can tell, people have problems with the seals
if sand/dirt is lodged between the case and seal. Manuals
emphasize rinsing in fresh water (with door closed) after each U/W use.
FWIW, the Olympus manual is terrible. A print version of the manual is not included. You have to download the manual in PDF and view on your computer/tablet. There are 6 different settings (Auto, Scenery, Aperture Priority, Macro,....); however, different combinations of buttons and settings a available in the different modes. After spending way too much time reading and reading the manual, I figured out that in addition to the shooting settings, the Up/Down/Left/Right buttons open menus for mode, zoom, flash, exposure and sequential/timer. The trick is different selections are available in each of the shooting modes. Then there's a set of commands on the 'INFO' button and the 'DIAL' does different things depending on the mode. Then there's press and hold functions. I made a little cheat-sheet boiling down 166 pages so I can understand how to use this camera. Now need to start taking pictures.
I think the little, "tough" TG-6 will be good for our continued sailing adventure -- hope to get some good photos this time around.
Thanks again for the ongoing discussion on cameras and underwater photography!
