In Topic: Spot light vs snoot for macro

01 July 2017 - 07:57 AM

Hey, as the title states I'm looking into either making (I haven't found any ready made snoots for my archon w42r's) or get a spot light for those macro night dives where you want the black background. It would seem like a spot light would be easier to handle and also simpler to get going with, but the results are what matters.

Any input is appreciated. Cheers

Following as I am considering the same.

I will try with my Archon on spot light only to start, and possibly drop by a local hardware / plumbing store to see if any standard pipe reducers would fit.

A low tech, and cheap experiment which I did for my YSD1 strobe. Getting a snug fit so it does not wobble will be the biggest challenge. Surgical tubing as a gasket was my first solution.

Will post pics if I cobble something together.

Still testing the camera, no footage to share, just experience. Tried the 60mm with the cmc-1. I don't have the focus gear so I was relying on auto focus--which I'm not all that happy with. Part of it is because I'm learning the general focus distance of the lens and the cmc. But, in general the auto focus hunts a lot. Even when using the back button focus lock. 
I also tried the camera in AFC in tracking mode. Didn't really work. Right now my preference lies with the 12-50mm lens for flexibility. But, I'll give the 60mm more tries.
I still find myself hitting buttons and dials I don't want to with dry gloves on. I'm going to try a thinner liner and glove on my right hand to see if that helps. 
I have decided setting the ISO to auto is probably the way I'm going to go. One less thing to adjust.
Hope you're getting along fine with the new setup. Please chime in a share any discoveries or more efficient setups.
Oh, I did place an order for the smallHD501 and na-502 housing. I expect to put those into action this weekend on next week.

Agree with what you say about the 60mm. It is a great lens, but has a fairly steep learning curve as it is much more powerful than the 12-50mm set to 43mm Macro. To limit focus hunting I set the focal range on lens to 0mm to 19mm.

I have the focus gear so especially when focus peaking (and optical zoom) is active it's easy to achieve focus at the START of the shot.... Confirming focus on a small moving subject during the shot is more difficult as the focus peaking dissapears.

Cannot wait for my flash so I can try focus peaking with still photography.

For the 60mm I find that if you have a subject surrounded by other things it can confuse autofocus. Try pre-focusing on something at a similar distance and it helps get autofocus in the ball-park.

Have only got the camera back in the water one more time. A dusk dive with 12-40 lens. Works with the tripod but I suspect it will not be super stable in current due to the size of the dome.

Lots of particulate in water so tried the spot feature on my lights to minimize backscatter. Interesting effect and will definately experiment more.

Video has always been an after thought for me, so still getting used to keeping the subject firmly in the focal range.

Will try to post some more sample footage.

I did a test dive in the south San Juan Islands yesterday and here are some uncorrected video clips. I shot in manual at 1080/60p and custom white balanced against 2 solo 3000 lights.  Use the Olympus PRO fisheye lens and the conditions were good enough viz wise to work with wide angle--which I'll confess isn't my strong point. Setting details are in the video. I was mainly trying to work with wide angle closeups. I ended up with a fair amount of footage out of focus. In manual mode I'd half press the shutter button to lock focus and then start recording. For the next fisheye tests, I'm going to just leave the aperture wide open and see how focus to infinity works.
Comments and critiques are welcome. My macro port arrives tomorrow and I'll do some tests with it this week as I have better competency with macro.

Nice, how do you like the Olympus fisheye? Is it challenging to light such a wide field of view without burning the edges?

I've been wanting something wider than my Olympus 12-40mm f2.8 PRO and still on fence between the Oly fisheye and Oly 7-14mm so would live to hear pros and cons.

Tried macro with my GH5 today for first time using spare 10" & 12" arms on the tripod ball joints. The 60mm macro is a bit challenging and the CMC-2 would be best left until I dial in macro on its own.

Conditions were challenging to say the least. River silt, plankton and a couple curious seals kicking up the silty bottom....

Would prefer to experiment on settings using the 12-50mm as it isn't quite as tight as the 60mm. Still waiting for the replacement gear set from Nauticam which works with GH5.

My housing arrived today so I'll take it for a dive tomorrow. Although, I only have the fish eye port. Macro port comes in next week. And, the viz reports are about 3-5 feet. So, it will be a chunky mess, but good for developing muscle memory where the controls are located.

Good luck and have fun with it

White balance looks great.

I'm axious to get my GH5 into cold water this weekend (conditions permitting).

The settings choices the GH5 are almost overwhelming relative to my Canon SLR so it's interesting to see what has worked for you, particularly given I dive in similar conditions (Monterey). I would not normally consider auto ISO as an option for example.

Also, I had not encountered the shutter angle option (thanks stphnmartin).



Hi Brad,


I tried Auto ISO because like you I find the choices overwhelming.


Basically I wanted to keep things simple, set a shutter speed, try Manual White Balance, start at f8 and go from there. I thought the added adjustments to ISO would be too much on my first dive, and besides I was curious to see what the camera would chose in different conditions. The more open green water shots were 6400 and the mid range shots 2500 with close ups and jelly shots 640 to 1600. It's not great footage & I have not pixel peeped, but with all the particulate I did not notice much graininess to the footage. May be different at 4K and clear water / lots of colour.


Perhaps once it is edited to get rid of washed out whites etc it could look worse, but compared to how my EM5 performed at high ISO I am happy.


Will try to get out to some of my deeper. darker sites in the next few weeks and push the settings a bit to see how it performs.


Considering you can access ISO by pressing a lever then spinning a dial I will be trying full manual settings soon, but one thing at a time...


As for cold water, even with thin dry gloves with liners all the controls were easy to use.


Will update over the next few weeks as I continue experimenting. The more we share the more we learn...
