Hi all, Guys, I (almost) did it. I tagged all 4500 pictures from my Philippines trip in April/May with the names of the species photographed. Almost: four pictures of two species are missing 🥴. 1) I found this critter while diving in Bohol, looks a bit like an orang utan crab and a hairy shrimp had a really good time together. If I recall correctly, this little guy was about 2cm (plus minus a lot? 🙈). I managed to take three pictures (photographically I'm not really happy with the perspective, but hope they allow identification) before he decided to hide. 2) Some kind of box crab maybe? All pictures taken with Sony 90mm / A7IV, Backscatter MF1+OS1. No editing done. If higher resolution would help, let me know and I'll upload it somewhere at 100% res and link it. All help in identifying those little crabs is highly appreciated! 🙏🙏🙏 Best, Fabian

Hi all, I'm getting a bit bored with most local lakes, so I started looking into the small streams around here. I struggle a bit with water clarity, although from outside it looks gin clear, underwater it's rarely more than 1.5-2m. Does anyone have some inspiration for this kind of photography? Appreciate all links, Instagram accounts and so on! Thanks, Fabian

Asking @Gudge might help? 🙂

Would be amazing if we could get something like this as well for other port sizes (e.g.140mm, 230mm) 😇

Guys, stop it... my bank account can't take this anymore!

Kudos to @ErikaNydaria, thank you for the domeport. Can absolutely recommend her as a seller!

Looking forward to some test shots! 😉

Sure, here you go. For those that not read the entire thread but only this post: open link, right click on image, open image in new tab -> zoom to 100% https://www.directupload.eu/file/u/80408/pras4rij_jpg.htm ISO 400, F8, 1/60s, 15mm (taken in shallow water but with little ambient light). Port setup as suggested by Nauticam in the port chart for the 140mm. Picture is edited in Capture One, but sharpness is only increased minimal. For comparison, the pike should be a similar distance as the sponges (if I remember correctly, but not sure with the thousands of pics on my drive, I could be wrong) No, I didn't, and as the 1.4x is shorter, it would require a different extension. I'd be happy to make test shots underwater with both setups, but it would require me a different extension (N120 20mm) and the 1.4x TC. If someone has both and is living somewhere in Baden-Württemberg (or willing to dive there 😄) , we can maybe arrange a day to take some proper test shots.

For a 100% crop: open the links, right click on image, select "open image in new tab" and then you should be able to see it in full resolution.

I'm happy with the results (still processing images from my last trip, but looked at a few to judge), just quickly exported 4 semi-processed images. There where not many situations that required the 30mm end (rarley shy animals), but hope this helps to get an impression of the quality: 16mm, F18, ISO100, 1/250s: https://www.directupload.eu/file/u/80408/yubehf35_jpg.htm 16mm, F13, ISO200, 1/100s: https://www.directupload.eu/file/u/80408/mq74kc3y_jpg.htm 30mm, F14, ISO100, 1/160s: https://www.directupload.eu/file/u/80408/yazmhih2_jpg.htm 16mm, F16, ISO100, 1/250s: https://www.directupload.eu/file/u/80408/wnzdo499_jpg.htm My conclusion: Sharpness is fine for me. Yes, the Canon 8-15mm without the TC is a bit sharper. I only see it at 100% zoom on a 4k screen, so what... Corners are also fine for me. In some images they are really mushy, but as this is only in some, I suspect this to be mainly due to DOF. One thing to mention is the light, so despite using similar appertures, I need to increase the ISO a bit compared to shooting without the TC. The increased zoom range (16-30mm) is definatly worth it, considering the price (< 1000€ additionally to the rest of the setup). In case someone needs some numbers to judge, I did a quick FOV caluclation (might not be perfect, just used the equations I found online), ignoring extension tube effects: Focal length FOV vertical FOV horizontal FOV diagonal 30 46 70 85 16 88 137 170 15 94 147 180 8 180 180 180

Nauticam Sony A6500 housing (NA17417) with 2 third party powerbanks and USB cable for use in the housing (to combat the A6500's power hunger), Nauticam M16 vacuum valve II (NA25625) installed, also included is the travel bag for the housing and a few spares. Asking price: 1400€ (2674€ new + batteries, which I can't remember exactly how much they cost, so in total probably just over 2700€) or best offer. Remark: In the pictures the N85 Macro Port 40 (NA36228) is still mounted but is already sold! Condition: very good, we can have a video call where I show you the details. Shipping is no problem (I'm based in southern Germany). Payment via PayPal, PayPal with buyer protection (if the buyer pays the fees), cash on collection, bank transfer. Private sale, no warranty or return.

Not exactly what @boduoguo asked, but this might be of some help:

Great pictures! I really like the background of the pipefish, gives it an artistic/abstract touch.

Yes, considering what I've spent, I'm happy. Quality is good enough for me, although it is a bit better without TC, and the versatility is greatly improved. Plus, I can use this TC topside as my longer lenses are Sonys.
