Shutter speed is important in controlling background exposure in flash photography. The flash controls lighting of the subject. Think of them as separate variables. Without a flash, this is different. Shutter speed is clearly important in stopping action, movement, stability. This is why you can shoot flash at slower shutter speeds, say 1/4th of a second, and the subject will be sharp but may exhibit signs of movement depending on how much ambient light there is. If you shot the same subject in complete darkness, that 1/4th of a second won't show movement in a frame because the flash stops all the action. High shutter speed sync is related to the camera's mechanical capabilities. Going beyond the camera's sync speed on the high end will likely create a dark band that didn't get exposed. Hope this helps!

Works fine for me.

It's nice seeing the animal peering from its shell! An excellent example.

Thanks for posting those photos @dhaas Good stuff, and I like the compact footprint. I'm waiting for a 1" sensor that focuses like a Sony, close up like an Olympus TG and has the battery life to dive all day.

Nicely done!

Thanks @DreiFish and @guavakal Well done!

From Phil: "I also use the 20-70 in the 180mm dome even though larger ports up to 250mm are recommended. This is overkill for me and I find the loss of sharpness in corners to be over hyped." I completely agree. If it's a technically perfect shitty photo, it's a shitty photo.

Welcome to Waterpixels. I think you will find that there is a learning curve to shooting underwater - all i good fun though.

Yes, there is a guy in California named Elie. See his Instagram page - Narcosis101. I've had a V serviced by him, and bought o rings and such. He can also pressure test your gear. I don't think he does RS gear though.

That's very frustrating and I feel your pain. I once had a lens get stuck on a flip holder after a dive, and I tried many of the suggestions above. I gave up and decided to make the lens/flip a dedicated unit. Then on the first dive back, I continued trying to loosen the lens - and voila! - it did. Maybe all those attempts with penetrating oil, strap wrenches, etc did the trick.

Nicely done!

My thoughts are said more expertly by @TimG , above. But the bottom line is know your audience and be ruthless in culling down to to the fewest images that tell your story. A portfolio, though, is an expression of what you consider your best work. A project or story is another thing. It's also good sometimes to involve other eyeballs to help shape your portfolio (for all the times your heart loves an image that means nothing to others).

Hi @StephanieW. I have both the Sony 90mm and the 50mm. The 50mm is pretty slow with early iterations of the A6xxx series, but I've used it with my current A7c and A6600, and it's pretty good once it locks on and tracks. Not great for quick grab shots, say a speedy fish swimming by or blackwater. It's a 75mm equivalent with the APS-c sensors. I use Nauticam N100 ports, the flat port 45 and a 30mm extension.

@ChrisH Wonderful images! Your model was spot on in every instance, and that one frame of the plane's lighted exhaust is fun!

Nice photo! And welcome to the forum.

It's nice to see a solution that isn't too expensive! Very good.

Hi Elvandar. Aloha from Hawaii and welcome to the forum.

Yes, that would be me. I’ll look for you.

Welcome aboard. Olympus is good stuff.

There’s too few of us to make a difference I suspect.

I would love to see a mass dive travel boycott to crush this rip off.

That whole trip sounds like an over-sold promotion. Very sad. You did make a couple of nice frames there, but I would be very unhappy riding around on a small boat all day without any promise of a time in the water with critters.

You might try finding used underwater gear here in the classifieds, or on ScubaBoard, and even on eBay. Facebook Marketplace may have some gear, depending on where you live.

I would trade my A7c system for the A6700 if I could. I have the WWL-1 and CMCs, so I'd be good to go. I would probably only regret it if I came into some money to buy a Nauticam Wide Angle Conversion Port or the new Fisheye C.P.

Re the Tamron 11-20, if a lens is not commonly used underwater, then it might be hard to find a zoom ring or you might have to 3D print one. The Sony 10-18 is more common, for example. I just follow the manufacturers like any good sheep. If you really get into underwater imaging, you'll be impressed by the machined aluminum housings made by a couple manufacturers. Very sexy stuff.
