Yeah, my wife and a couple of others in the group that I travel to Roatan with routinely carry magnifying glasses underwater. I love that Arrow Blenny shot, but all of yours are really nice.

One other thing to consider is an external monitor. I exclusively shoot video, so that was essential for me, but it certainly makes it much, much easier to see what is or isn't in focus. It does add a lot of cost and complexity to your apparatus, though, and adds to the drag of the system while swimming. So, there are trade-offs, but for me, an external monitor helps immensely.

Lol, I can certainly understand that part. Whenever I clean up the dog hairs from my single Golden, it looks like I should be able knit a sweater from all the hair.

Thank you, I appreciate that - and sorry for the thread hijack.

I agree that this is likely to take a while to resolve. Also, I want to point out that Biorxiv is for preprints, that is, they have not gone through peer review yet, so be very cautious about anything published there. It could well be correct, but also might have errors in methodology or analysis, for example. I am not saying that it is wrong, but to read papers there with a higher than normal level of skepticism.

To those of us who are firefighters and EMTs (ie, first responders), DRT = Dead Right There

Congratulations, nice work! (BTW, as aside, DRT has an entirely different meaning to EMS first responders...).

Wonderful images, thanks for sharing. They are inspiring.

Having been to Cuba and having dived the Gardens there, I can tell you that the crocs move pretty quickly and follow focus is important. I was shooting video, so this may not apply to you. However, they do get close, so a shorter lens is probably good as TimG says. One meter or less is not uncommon. It is a very cool experience, have fun! I would love to go back someday.

Very nice, thanks for sharing. I will be in Roatan again in a couple of weeks, and can't wait.

I love that shot of the tunicates, beautiful color.

That must have been an amazing trip. Thanks for sharing.

Back in the dark ages, when I worked as a mechanic's assistant in a gas station at 16 years old, we would use Coke to clean the corrosion off auto battery terminals. The phosphoric acid in it works well for that, but then you need to flush it thoroughly with fresh water to remove all the sugar. I have used this trick multiple times since then.

Thanks, 'll be there in mid-February - hope you have great trips as well.

Very nice, I recognize some of those spots. You found more nudibranchs than I normally see, so I guess that I am going to have to look closer. We just bought our airline tickets for our next trip back to Roatan, and I can't wait.
