Price drop: $100.00. Moving up to a Nauticam CMC-2 for my OM-1 kit, so this great starter lens needs a new home.

Oh, I see that now. I will consider it. Thank you.

The zippers are an excellent point. I had not thought about that. I think I am going to return the AO Cooler bag and get the Kraken Rinse Bag just for that reason. I appreciate that. However, from what I read, that bag will not hold water, and I want it to serve as a rinse tank.

Although I do understand Dave's point of view, I lean more in your direction. It's too easy for me to get distracted and leave my gear in a big rinse tank. I've done it at dive shops before. I'm probably better off keeping it as close to me as possible. I looked at the CineBags, but it's not available anymore, is it? The Kraken Rinse Bag looks similar. I went with the AO because it's significantly cheaper and I don't think I need all the pockets, etc. Now, I just need to decide on the logistics, keeping in mind I need to take care of my back while traveling. I might just stuff it full of clothes and then stuff the bag in a suitcase. I already have a spinner carry-on camera bag for the most critical camera gear.

Hi everyone, I’m heading out on my first liveaboard this August—the Nautilus Under Sea in the Sea of Cortez. While I know they have dedicated communal camera rinse tanks, I’m debating if I should still bring my own personal container. I bought a 36-can AO padded cooler to use as a dedicated rinse/protection station, but I’m hesitating because of the weight and bulk. For those with liveaboard experience: Is a personal rinse bag/cooler worth the luggage space, or are communal tanks generally safe enough for a mirrorless rig (OM-1 in an AOI housing)? Is there enough deck space for everyone to have their own "tank," or will I just be in the way? I'd love to hear your thoughts on whether to pack the AO cooler or switch to a lighter, more collapsible setup. Thanks!

Purchased new and sent to Backscatter last August for routine service. They replaced it with a brand‑new housing with upgraded hardware, so this unit is effectively new.

Asking $699. Located in Texas; can ship within the U.S. Additional close‑ups available on request.

Selling my Fantasea UCL‑05LF close‑up lens. This is a +6 diopter wet lens that adds noticeable magnification for macro subjects while maintaining comfortable working distance. Great for nudibranchs, small fish, and detail work without committing to full supermacro. Optics are clean with no scratches, haze, or coating marks. Threads are smooth and corrosion‑free. Used only lightly and always rinsed and dried properly. Includes front and rear caps. New retail is $180 — asking $120. Located in San Antonio, TX; shipping included for U.S. buyers. Local pickup available.

Hey, Dave, this looks really cool! I wish I could get something like that 😜.

I think it depends on the camera/flash trigger/strobe combination. For my OM-1, AOI housing, and Ato Chris, I spoke too soon, and too uninformed. Backscatter has confirmed to me that there is no disadvantage to leaving FP on at all times that RC is on. RC will simply perform as usual before the flash sync speed of 1/250, and as HSS above that. So, essentially, it does support Auto Super FP. I apologize for my ignorance.

As you suspect, for my gear combination (OM-1, AOI housing, Atom flashes), the flash output would be reduced if Super FP (OM name for HSS) is ON, but shutter speed is below flash sync speed of 1/250. Super FP should only be used at speeds above that, then. As I understand it, other cameras might support Auto FP where this would not be true.

Having finally gotten my OM-1, AOI UH-OM1II housing, and dual Atom Flash strobes, I can verify that HSS does, in fact, work in RC/SC mode. You just switch FP on in the camera, leave the strobes on SC, and you can increase shutter speed to your heart's content (or until full power isn't enough from the strobes, at which point they beep). This is true on a tabletop, not yet in the water, though.

Maybe I just made that less of an issue...

The advantage is ditching about 300g underwater. I'm hoping to use 5" arms for macro and having a hard time arranging enough floatation, whether with float arms or STIX floats.

Well, I shoot in clear, blue water (Caribbean). Also, the target light on my strobes (Backscatter Atom Flash) do have the same beam spread as the flash itself. That's why I thought I might not need the focus light for macro.

Thanks!

That's interesting.

That's exactly the setup I have.
