It could be. Hard to know how much color variation there is, but the Fishbase photo looks like more contrast between the light and dark bars.

Have you considered a 30mm macro? I had significantly better luck with things like turtles and bigger fish compared to the 60mm macro, but of course you give up working distance (and the ability to use diopters). I have a proper short port for the 30mm on order and will see if that lets me do acceptable macro (if not super-macro) on my next trip. I'm not sure it checks all your boxes, but it would be super compact and light (and potentially cheaper), compared to 60mm+MFO-3. I should mention that I have also used the 12-45 in a semi-dome port. It's not even a slightly scientific comparison, because I mainly shot with the 60mm, but of the the images I took on a recent 2 week trip, only one of the keepers was at the 45mm end. I did keep a couple "close focus wide angle" style shots at 18mm and wider [1]. I think it is possible I may get better at those, but the focus distance at 45mm is just too long for macro (at least if you are used to the 60mm).

Does anyone recognize this fish from Sogod Bay? I have the focal distance recorded as 0.2m on the Oly 60mm macro, so it must be fairly little. The shape looks a bit like a triplefin, but the shape dorsal fin isn't very clear to me. Alas, I don't have a picture from the side.

This is not exactly a wide zoom (12-45) but you can see some shots at 12mm in the AOI 4" semi-dome port at https://www.mu-43.com/threads/olympus-12-45mm-f-4-pro.107818/post-1795979 My impression is that this is a lot sharper than my old 12-50 in a flat port, but of course I could be biased. If you don't need to go very wide, this port is not too expensive (around USD300 when I bought it). I think the 9-18 is the only other wide-ish zoom AOI says is compatible. I had the impression the UWL-400A is designed for the smaller sensor TG5/6/7. Before you buy one, make sure it will work with a mu4/3 sensor.

Is there any important difference between the Q1RC and the Q1i other than support for the Sony TTL mode? If not maybe us humble OMDS users can get a deal on Q1RCs.

@Stig Consider one of the bodies supporting PDAF autofocus, OM5 or OM1. I don't know if it is just a different camera generation, but going from an EM-5-II to an OM-1 is a huge improvement in autofocus performance. AOI makes fairly affordable housings for the OM5 and OM1 also. I'm a happy recent adoptee of their OM1 housing. I think @bvanant has the same housing, and he actually knows how to use his 😅.

Bought a CMC-1 from @Brandon Cole and it looks exactly as advertised. Transaction was smooth, things happened when and how Brendan said they would. 👍 P.S. For those wondering about parcels crossing the US/Canada border, I got hit with sales tax (HST), but no duties or tariffs.

Thanks, I see it now. My screen is 2560x1440, but I only use full or half width (tiling window manager), and also use a fairly high enlargment (C-+) in the browser, so I probably see the "responsive design" before most people do.

Unless I have the browser full screened, the site switches into some (phone friendly?) one column mode and I can't find the "Mark Site Read" button anymore. Please feel free to embarrass me by pointing out where it is 😅

Sure the metering is the same, but Tv and Av will have the same problem with stobes in manual mode: the camera will assume things are very dark, and once the strobes fire things will (most likely) be overexposed.

I would think the former would not work, since the ISO will be set based on some kind metering, which will probably happen before the strobes fire? I think I used to do the latter fairly often when I had an sTTL setup. I can't claim the results were great, but there were many reasons for that (including me).

Does anyone have experience to report with Onderwaterhuis.NL Flip Adapters? I am in particular interested in [1] to mount a Nauticam CMC-1 and a weaker Inon diopter on. I am currently using a howshot swing adapter [2], but I'm thinking this will introduce more distance between the front of the port and the CMC-1 than is ideal. It's also only a single lens holder. Other suggestions that would work on the 120mm diameter Olympus flat port welcome. I think the AOI [3] is probably an option, although its more expensive.

Are you willing to ship to Canada? I'd pay reasonable difference in USPS shipping.

Basically the same bungee solution as mentioned above https://scubaboard.com/community/threads/harness-mount-for-shearwater-peregrine.644620/post-10253788 It works for me because I mostly keep that first strobe arm close to horizontal. So far I've done about 30 dives that way and no complaints.
