#383895 Panasonic GH-5 lens selection WWL1 or wide-angle

Posted by adamtaylor on 08 May 2017 - 05:09 AM

Personally I find the 12-40mm my preferred lens if conditions are reasonable for wide angle. And even when the top 20-30 feet are soupy and it dark down below it can still collect alot of light.

Not super wide, but when you find a reasonably small critter you can zoom in to 40mm and get some close ups, or fish portraits.

I find the 180mm dome a bit bulky, and it really changes the buouyancy characteristcis but if you like over-under shots it works well.

That being said I would prefer something wider....

#382918 Nauticam dealers now list part 17713 for NA-GH5

Posted by adamtaylor on 07 April 2017 - 12:28 PM

Yeah, I watched that video previously. It performs better, but still kinda flakey. I have a GH5 and am deciding if I'm going to keep or return it. I have just the 60mm lens to test with. Moving from a dedicated video camera to mirrorless is a big change. 

Stephen, if you do keep it and get the GH5 underwater in the Northwest please post comments.

My EM5 struggles with focus at times, especially with the 60mm in waters near Vancouver. Be interested to see how the GH5 compares.

There is alot of fresh water mixing near the surface at many of my regular sites. So I imagine any camera will struggle focusing through changing water densities...

It is a big financial commitment to purchase a GH5 and housing, even if my current lenses and ports are compatable. Seeing some real world results and reviews will be required before I make my decision.

#370303 Vancouver Aquarium Allegations

Posted by adamtaylor on 09 February 2016 - 11:01 AM

I will have to watch the video to comment on it's content, but have heard LOTS of chatter about it. From what I have heard the 'documentary' is very biased and some information has been used out of context.


Perhaps someone with more knowledge of the specifics can comment?


Having been involved in a number of Citizen Science and Marine Conservation initiatives with the Vancouver Aquarium I have nothing but respect for the individual researchers and the organization for it's efforts in those specific areas.


Before tarring the whole organization with the same brush consider both the source of the video, and the other initiatives the Vancouver Aquarium is part of (science, conservation, education, marine mammal rescue / rehabilitation etc)


I will reserve judgement on the whales in captivity part until I have time to watch the video.


This issue, and discussing support of the organization should be relevant to the Underwater Photography Community as they have a number science initiatives that local underwater photographers can and do contribute towards. Off the top of my head these include; Rockfish Surveys, Annual Lingcod Egg Mass survey, Sea Star Wasting Syndrome, Glass Sponge Reefs etc.


Input from their researchers and support from the organization has helped with numerous conservation issues over the years which are directly relevant to Scuba Divers and Underwater Photographers. Some of these include creation of Rockfish Conservation Areas, reintroduction of Black Rockfish to Howe Sound and Bottom Fishing Closures for Straight of Georgia Glass Sponge Reefs. Aquarium staff are working with other non-profit groups that I am involved with on two other glass sponge reef initiatives;


1) Proposed expansion of Halkett Bay Provincial Park to include glass sponge gardens and glass sponge reef (bioherm) all of which are within recreational scuba depths.


2) Expansion of Bottom Fishing Closures to include ALL known glass sponge reefs in Howe Sound (5 of which occur shallow enough for air diving which is unique in the world).

#358852 Olympus 7-14 mm f2.8 will not fit in Nauticam housings

Posted by adamtaylor on 14 March 2015 - 06:00 PM

I have the 180mm glass dome and extensions for my E-M5 Nauticam Housing and use with the 12-40 f2.8 lens

Works great, took a little getting used I the size, and attaching the lens to camera body inside the housing & THEN securing the port with extensions attached.

Considering the only other ports I had used were the flat port for 12-50 kit lens and the 4" mini-dome for the fisheye I will admit to being nervous about the slight movement of the multiple parts.

System has worked flawlessly since I got it

Love the lens, and the ability to get wide-angle images even with the low viz waters around Vancouver, British Columbia.

Zoom for the 12-40 is controlled by the knob on the housing. Had hoped that the focus knob on the adaptor port would be able to achieve manual focus, but have not figured a way to have both zoom and focus gears.

Will definately be having a close look at the Oly 7-14mm when released. The wider angle would be nice.
