Just my own 2 pence on the Sony side. I've been using my A7C for about 5 years now in a Nauticam housing and YS-D1/D3 strobes. I went that route coming from an RX-100 in Ikelite housing, to keep the overall housing smaller. I basically have three combinations that seem to work, depending on the environment: 1) Most versatile: Kit 28-60mm lens, WWL-1B, and a CMC-1. I've captured Wire Coral goby, then 5 minutes later (attached pics) a porpoise pod, and it all fits in a single travel Pelican Air. 2) Macro: Sony 90mm with MF-2 strobe and OS-1 snoot. Recently added an MFO-3 which adds a sizable amount of versatility to the set-up. For travel, now I'm also stuffing photo gear into another backpack for Macro and WA. 3) WA: Trying to keep things compact, I have the Canon 8-15 with metabones adapter, with the Zen DP100. Good dome for close focus/WA, but I'm kind of thinking about a slightly larger dome like the Nauticam 140mm to improve the IQ on the Zen's softer edges. Anyway, just another opinion. Jim

I'd be taking the MFO-1 along and try it on the trip as well. It doesn't take up much room, so why not. Try them both side by side and see what works best for you. Stick it in a pocket and swap it on the adapter as wanted. If you still want to get rid of MFO-1, let me know. Shooting with a Sony 90nn FF and looking to pick one up.

I suppose most didn't catch Matthew's comment, but I'd also be interested in how other color-deficient folks handle that defect. I also have a bit of red-green deficiency but rarely have someone tell me my colors are out of whack.

Thanks Dave, that's what I was looking for and aligns with my thoughts as well! Where'd you find the sea spider?

Thanks Chris, cropping has generally been the practice so far and looking at the general utility. Here in Seattle and our Pacific Northwest, we have our share of the macro critters but there may be more utility in the MFO-1 on a regular basis.

Looking to add to the equipment collection and considering either the SMC-3 or MFO-1 (already have the MFO-3!). I know they are designed for different uses, but from your own experience, is one or the other more useful. For macro, I have the Sony 90mm (on A7C) and have CMC-1 and 2 for use with the kit 28-60mm lens (and they work great), but at times getting a little more magnification on the 90mm without a TC would be nice. Otherwise, having extra depth of field and less hunting on the lens make the MFO-1 a good option. Couldn't find a good thread for both of these lens, so I'm just looking for opinions.

Aren't the softer edges expected with the 140mm? I shoot a Zen DP100 with the Canon 8-15 (Nauticam NA-A7C + N100 ->N120 converter (no extension)) and run into the same, It's just the limitation of the dome size, thus the advantages of the larger domes. Can that be minimized with extensions?

I have two bayonet caddies on the camera rig, one on a float and one on a separate stub arm and can swap lens in a couple seconds. Thought about the pocket solution, but with dry gloves, it just doesn't work.

Not the first blackwater dive in Kona, but the first time using the new MFO-3/ Sony 90mm on A7C and MF-2 strobe. Seas were running 5-6' on the way off-shore, but diving was pretty calm. I always find it interesting that there's can be variation in the various critters from dive to dive.

Kind of depends on what you're doing. If mostly snoot, then attach, if mostly macro and occasional snoot, I store it and attach as necessary. I had a large Marelux snoot that barely fit in a large drysuit pocket, but the Backscatter OS-1 easily clips off with a small bolt snap to the camera tray.

Backscatter OS-1 Snoot caddy uploaded to Sketchfab: https://skfb.ly/pDRKG. I've added some splines on the Mini-Flash end which match nicely with the features on the MF, it's a snug fit, but it doesn't rotate around the MF.

I currently have a small bolt snap on the OS-1, but thought a mount clip would potentially work as mine is usually off by default. The example on Printables has the aperture slides; nice touch. Always takes about 3 to 4 iterations to get these things right, if not more!

Has anyone made a caddy clip for the Backscatter Mini Flashes to OS-1? If not, looks like I'm off to another project.

Adding to the MFO-3 posts, I had a chance to try the lens with my A7C and 90mm macro in our wonderful Puget Sound Seattle water yesterday AM. The rock fish pics are with the MFO-3 and without, from about the same distance from the fish. The Sea Angel was just flapping in the water column and is about a centimeter in length, so approximates a lot of the Hawaiian blackwater critters. For blackwater, I think this provides a very nice solution from what I'm seeing. Storing the lens is a little more difficult than the smaller CNC diopters and I usually use the bayonet mount. I can see why a flip holder is going to work out a better! There was also negligible weighting issues with that lens being so far out in front. Only one dive so far, but this looks like a great lens. .

Do you use the nauticam with that setup or would those lenses fit with the ikelite? Because the 28-60 does seem to fit a lot of criteria in that case. Yes, I'm using the Nauticam NA-7AC housing.
