All Activity

Not the first time on that reef either. I was on board the Eco Explorer out there in 2006 and had a fabulous week. It went aground the following week. I believe it never returned to service after the accident.

I use a 10 second time out with the A7riii to lower use, plus C3 to swap to back screen.

As others have said, I have set a button to toggle between the EVF and LCD, and you need to disable the autoswitch which is normally useful on land. In addition I have also set a button to disable the display at all, in an attempt to conserve some battery - this was a fairly useful trick on the A6xxxx, and is faster and less error-prone than the global power switch. But to be honest, on the A! I haven't seen that much battery savings with that trick and can comfortably keep the camera running for 3 dives with the EVF set to 30 fps. Higher fps = higher battery usage. Update to the latest firmware as well, the most recent versions seem to have improved overheating and battery consumption compared to the first versions.

Totally agree. There seems to be one every few weeks.

nice collections

In my view (finder), def a fisheye for whales, whale sharks, manta rays and friendly sharks (baited), reef-scapes, big aggregations of fish and perhaps wrecks. A WACP / WWL for manta rays and baited + chance encounters with sharks, reef-scapes and fish aggregations of fish / schools. Others might do it different. Rectilinear 16 mm, 105 degrees FoV. A little bit more wouldn't have hurt.

Yes! I took these images at Magdalena Bay last year snorkeling. The first humpback shot was taken from about 2-3 feet distance. I don't think this would have been possible with a rectilinear lens. If I did this again I would probably add a 1.4tc to the lens. You can still get the same width at 11mm but you have a bit more reach when things are further away.

Just need to order the old Kraken bulkhead. New one is perma attached like Nauticam and its M24 only. Looks like the isotta housing has three M16 holes. New and old Kraken side by side (old on left)

Great image!

So you'd take a fisheye for whales? I always thought it was better not to go too wide with large pelagics. I photographed orcas and whales in Norway with my 16–35mm, and that worked well. Sure, there were moments when it wasn't quite wide enough, but at the same time the animals were often farther away than expected. I don't really know how close they typically get in French Polynesia, though. I don't have a huge amount of experience shooting whales...

You are referring to the USB-C bulkhead? The Nauticam right angle plug only just fits through the special M16-M24 adapter, it has to be angled through, If you had a right angle USB plug you could see if you can squeeze it through the M16 on your housing, bearing in mind that . The Kraken bulkhead might be a safer bet as you plug the cable in from inside the housing and it doesn't need to go through the m16 hole.

Agree somewhat. Often numbers don't tell the whole story. Anyways, 11 degrees (107 on wwl/wacp) difference horizontally makes for quite some difference in many UW shooting situations inme and inmo. The "square" you have available to frame your image from a desired distance (less than 1.5 metres, preferably less) is quite a bit larger with a wacp/wwl, compared to a 16 mm rectilinear lens. Shooting style and preferences then vary of course and different shooters want different solutions. The WWL and WACP (full disclosure –– have not used WACP, so merely a qualified guess) have some mild barrel distortion, but not as much as a full-blown FE. Kind of like the Tokina on DX @ 16-17, perhaps a little less. Fisheye 180 degrees, trying to make use of the diagonal FoV.

Well, ??????? dived Siren fleet 2006 with their first own designed/built boat together wit the owner in Andaman Islands/India. Again several times later on differnt destinations, last time Tubbataha with P. Siren in 2023. Loved their concept in the beginning. But the company has changed a lot. I also missed one trip in Timor with them due to loss of the liveaboard short before departure. As far as I know they lost all of their original boats except Palau Siren (which has already run aground in the past). From my point of view too many accidents with liveaboards these days. May be more liveaboards----more accidents. I do liveaboards since 1992 but current I'm feeling a bit unwell booking next trip. Br Markus

Actually quoting diagonal fields of view is a bit misleading when comparing rectilinear lenses to barrel distorted wet optics as with barrel distortion the corners are stretched the most. It would be quite rare to place a subject like a whale, a shark or even a wreck along the diagonal axis, rather they are placed along the horizontal axis typically, so in my view comparing the horizontal fields gives a truer picture of the difference in subject size they can accommodate. The horizontal field of a 16mm rectilinear is 96 degrees, while a WWL at the widest is about 106 degrees in the horizontal axis, which is about a 13.5mm rectilinear lens horizontal field. so the horizontal field of view is only 10 degrees wider not 25 degrees wider. All that said I wouldn't take a bit dome down to shoot whales if i Could get similar fields from the smaller wet optics. A fisheye has a 144 degree horizontal field in comparison so is significantly wider.

Thanks Davide. I just do a simple MWB without any filters.

Just checking, are there any news on these?

Good editing and nice ambient light colors in Canon style. Did you also use a red filter or did you just do a simple MWB? ciao

Yeah that's a great point :)

I know nothing about the printer - a friend did 2 floats for me in your recommended filament material (dont want to say the wrong salt-water compatible type). One came out looking a bit squashed on one end and is a firm fit over the port; the other as you see is appropriate shape and is slightly loose on the port. Have yet to get either port float wet... Lembeh/ Bangka in July-Aug... I did use the MFO3 bumper on multiple dives in Maldives with no scratches on the glass to report!
