I measured my Nauticam a6700 (N85) at 11.75mm from camera flange to housing flange. I’ve got a few ports/adapter handy to measure if the desire is there. Now I need to go figure out the optical center of the Zen DP170 (N120 mount), and I will measure the EP of various FL of my Sigma 10-18. Yes it’s all APS-C which is blasphemy to some, but at least the measurements will be available for someone who wants them.

I recently picked up the Sigma 10-18mm 2.8 and a Zen 170DP to use with my a6700. It is a replacement for my Rokinon 12mm f/2. The Sigma is a much sharper lens than the Rokinon, and while I don’t have a zoom gear, I’m used to a single FL when shooting wide angle anyway, so I just need to play with it in the pool to get everything dialed in. It also has a much shorter MFD (4.6”/11.6cm versus 7.48”/19cm) and a much larger max magnification at MFD (1:4/0.25x versus 1:11.11/0.09x). Once I get it in the water I will report back on the combo, though that probably won’t be until Feb for some dives out of Riviera Beach/Jupiter. Before then I have to stay local which means macro only given conditions in the Gulf of Mexico.

Unfortunately it seems like there wasn’t anything announced, at least as far as my internet searching goes. Which is too bad, because I really want to see what Inon is cooking up, given all the recent strobe releases. I really like my D200s but want something with more power, and was/am holding out for at least the announcement.

It's all good! That frogfish looks awesome. Was that video taken with the A7C?

@humu9679 thanks! I've yet to run across a frogfish, even with all the dives I've done in every season at BHB. Someday I'll find one!

It’s external focusing, so it extends quite significantly to get to 1:1. You’d need a very long flat port to let it get all the way to 1:1, and you’d very likely have a decent amount of vignetting on the low end of the magnification scale. Is also as long as the Sony 90mm before the focus extension (131.5mm vs 130.5mm). If we make a rough estimation from the photos of the extension length, say 45mm, that puts the 1:1 length at 176.5mm. With a MFD of 238mm, we have a working distance of 61.5mm (2.4”). That’s really close.

I took my new a6700 and Nauticam housing out for a few dives a couple of weekends ago. Pretty pleased with how these turned out. Ciliated false squilla (Pseudosquilla ciliata), working on its burrow, Blue Heron Bridge, Riviera Beach, FL Whitespeckled hermit crab (Paguristes puncticeps), Blue Heron Bridge, Riviera Beach, FL Spotted scorpionfish (Scorpaena plumieri), Blue Heron Bridge, Riviera Beach, FL Green Moray (Gymnothorax funebris), 4th Window, Riviera Beach, FL Honeycomb Cowfish (Acanthostracion polygonius), 4th Window, Riviera Beach, FL Balloonfish (Diodon holocanthus), 4th Window, Riviera Beach, FL

Not sure who else saw the announcement a month-ish ago, but Tamron has released a new 90mm macro lens (Tamron product page) for both Sony E and Nikon Z. It has fast AF, reviews of it have it coming in pretty darn sharp (at least on par with the Sony and the Sigma macro offerings), and an MSRP of $699. A few things to note: It's about 5mm shorter than the Sony 90mm at 126.5mm MFD/MOD is listed as 230mm, so you end up with about 4" of working distance before any distance lost to the port it's behind, compared to the 5.8" of the Sony. 12 blade aperture, minimum aperture of f/16 Weather-sealed barrel I'm considering picking up a copy to see how it compares to my adapter Canon 60mm. A few thoughts on that: The working distance at 1:1 are effectively the same between the Tamron and the Canon The fast/modern AF mechanism might be a worthwhile upgrade, even with the most recent firmware for my Metabones mk IV I would probably benefit from an increase in sharpness If anyone here has had or will have a chance to play with one, I'd love to hear your feedback.

The camera has been sold elsewhere, so all that is left is the housing and related components. Willing to entertain reasonable offers, figuring $500 for all of it including shipping CONUS, split shipping if elsewhere.

Price drop to $900 plus shipping costs.

Hey @TURTLE-Balage, I appreciate the offer! I decided to see if I could get it apart and fix it up myself (because I'm probably a bit nuts). That didn't turn out too well, as it looks (after the fact) that the hot shoe connector is soldered to the IC board, and I broke those solder points doing the dissection. I wouldn't feel right sending it in for repair now, because I definitely made it worse. I liked this trigger, so I went ahead and bought a new Smart 2 from Backscatter (it was delivered today), and am going through the setup now. Planning on taking it out in a couple weeks to put it through its paces.

Battery life was atrocious on my A6400 before I switched to an external flash trigger. Once I did that I could eke out two dives on one charge. As for the bodies, I know with the SeaFrogs/Salted Line housings, they use the same one for a6000/a6100/a6300/a6400/a6500. The majority of the button placements are the same/similar enough, but the rub is the physical dimensions. The 6000 is noticeably thinner front to back than the rest of them (approx. 26mm vs 31mm, as measured on the orange line). SeaFrogs gets around this by using a kit that essentially "shims" some of the dials so they touch the body. I don't know if you'd have that flexibility with the Nauticam housing, especially since the change is dimensions is going the other way (thicker camera in a thinner housing).

I've seen this topic (Housing Flange Distance) but as you say most all of the discussion is around the FF bodies/housings. So once I get my things I would like to get some sort of searchable database going. Maybe if I have some success at getting data I can post an article/link here for all to use... Aha! That (the port ID) one of the things I'm hoping to compile into a convenient list, as I can't find anything of the sort on Nauticam's website proper. I went with a N85-N120 adapter just in case, so I'm good there! Glad to hear there are actually other APS-C Sony shooters in Nauticam here! As I've mentioned elsewhere, I've been using the a6400 in a Salted Line housing for a few years, and I've never been satisfied with the housing (neither build quality not ergonomics). I had seen this before and also balked at the price. I don't need access to the AF/MF switch, and if I have to get an N85-N120 adapter for my WA lens, it didn't make sense to me to get this instead of finding a macro port of the correct length. I've done the same. I've always hated having to crack open my housing to change batteries on a wet, rocking boat. It just makes me nervous.

I had (well have) an A7 IV, in addition to the a6400/Salted Line housing. After doing all the math it’s about $3k-4k cheaper for me to sell those bodies (and lenses I am not using anymore) and buy a full Nauticam kit for the a6700, including a new body. I’m able to sell my IV for $1550 to Keh, and my a6700 body only cost $1400 after taxes. I also already have the appropriate lenses for shooting APS-C, and don’t have FF equivalents, which means more $$$. But cost isn’t the only factor. The a6700 housing is a tad smaller and 1kg/2.2lbs lighter than the A7IV one, and the ergonomics of the SeaFrogs housings have left me unimpressed for the last 4 years.

I'm moving on to a new A6700-based setup, so it's time to part ways with this one. I've got a 1 year old Salted Line A6xxx housing. It's the Gen 3 version. I have the following available: A6xxx housing in white 8" acrylic dry dome with sunshade There are a few light scuffs, I've buffed them with Novus polish, and don't notice them on my images 6" acrylic dry dome with sunshade A few moderate scuffs. I haven't tried buffing these ones 4" acrylic dry dome Some deeper gouges. I haven't tried doing anything here, and don't shoot fisheye, so I don't know if they'd show or not Flat short port with 67mm threads 2x Standard flat ports 2x zoom gears for Sony E 16-50mm 2x zoom gears for Sony E 10-18mm Focus gear for Samyang 8mm F2.8 KitDive aluminum tray with 1" ball mounts VPS-100 vacuum valve kit Lots of o-rings, lubricant, and assorted spare parts Sony a6400 body includes one Sony NP-FW50 battery, AC-USB charging brick, and an off-brand battery charger SmallRig cage with wooden handle and detachable side L-bracket Sony 64GB SDXC V60 memory card Sony FE 28-70mm f/3.5-5.6 lens Also included is a Sony A6400 body and Sony E 28-70mm f/3.5-5.6 lens, along with a zoom gear for this lens I fashioned from the SeaFrogs focus gear intended for the Sigma 16mm. The body has a shutter count of approximately 16,500, has some minor wear on the top edges and on the bottom front edge. Includes all the accessories shown in the photo. Totaled up, this all would cost just shy of $2,600 new. It's been used, the domes aren't perfect, but it all works well. I'm asking $1,250 for the whole kit, plus actual shipping costs to you. Based on the quantity/size of the box needed, it would go UPS/FedEx, insured with signature confirmation. I'll accept PayPal G&S only (for both our protection), unless you happen to be in Pinellas County, FL, in which case I would be willing to meet up in person and take cash/Zelle. I'm happy to take more photos of any item you want to see more detail on, or answer any questions you may have. Thank you for taking the time to read this (quite long) post!
