Prescription Masks
There is a big push here in California to do "clear lens replacement" which is IOL surgery without cataracts. The big selling point is that you will never get cataracts (while true is a bit disingenuous since they take out the lens that could get cataracts). I just received today my new dive mask from Prescription Dive Masks in San Diego. Vision looks fine but will be out of the water for a couple more weeks so I won't get to test it soon. I got it from them at the Long Beach Scuba show, $400 which includes the mask. There was a company selling progressive lenses for masks, but they were like $700 and I am not sure that progressive masks make much sense. Bill

Macro gear with near unlimited budget
Well the new Canon 100 macro for the R5/6 is amazing. Jeff Laity has some awesome nudibranch shots from local SoCal waters with it. Bill

Diving with the Weefine 3000 CCW Ring Light
Don't tempt me. Working through the trip images now. BVA

Diving with the Weefine 3000 CCW Ring Light
It works fine for what it is. If it had 1 stop more power it would be awesome. Someone asked did I get it for free? and the answer is no I paid for it at Divervision. I think if you are shooting full frame it might not be as useful but to make a really compact system (no arms and only one handle) it is a good answer. Bill

Diving with the Weefine 3000 CCW Ring Light
I have long fascinated with shooting ring lights underwater starting with the Inon Quadflash, through the various Athena modifications to Sea and Sea strobe heads, continuing to the Saga fiber optic rings and now to the Weefine 3000. The Weefine 3000 is the latest version of the LED lights made by Kraken and Weefine. The Weefine 3000 CCW Weefine 3000 CCW Ring Light It's similar to the earlier 3000 lumen LED modules but has adjustable color temperature and a 3000-lumen burst (strobe) mode. It also has a super closeup mode that can shoot subjects as close as 25 mm (1 inch) from the strobe. It is powered by a protected, 26650, 5000 mAh Li battery. The battery can be charged via a built-in USB-C port. One very neat thing about the light is that it allows for a very small, compact system underwater. No arms necessary, just the camera/housing/port and a single fiber optic cable. The light is shown below on an AOI housing for the OM-1 camera. AOI housing for the OM-1 camera with the Weefine 3000 CCW Ring Light The ring light can attach to any port with a 67 mm thread and can be rotated for any angle once attached. One nice feature (or bug) is that when you are using the light in the strobe mode, it remains on at low power to act as a focus light. During the day it was not terribly necessary but worked fine at night, although you will also need some kind of dive light to find your way. My wife said it was very easy to find me in or small group, just look for the circular dive light. How well did it work? Better than I had anticipated. Years ago, I had the Kraken version of this light, and it was fine; this version with improved ergonomics (no multiple button pushes) worked great. Here is a nice little clown (Triopha catalinae) from a dive in local Southern California waters before the Raja/Triton Bay trip on the Wellenreng. This was shot at 1/160 sec, f/7.1, ISO 200 using the Olympus 30 macro lens on an OM-1 in an AOI housing. Certainly, enough light to illuminate the subject, I slightly reduced the shot exposure by 0.1 to increase the contrast a bit. For other local subjects, such as this anemone it also worked well. This one was shot at f/5.6, 1/160 sec and ISO 200. I shot with the light quite a bit on our trip to Raja/Triton Bay. Here is a nice little Goniobranchus coi, shot with the Panasonic 45 lens, f/6.3, 1/160 sec, ISO 400. I was very close; you can see the out of focus gills. I love Christmas tree worms, here is one from Triton Bay. Same lens, 1/250, f/7.1. Here is a crinoid shrimp, same settings. I shot a lot of tiny things, but also a bunch of anemone fish. Here is a Clarke in an orange anemone. f/14, 1/250, ISO 400. Overall, the light worked well for the things I was shooting, it of course is completely useless for anything more than 250 mm (10 inches) away. The color temperature is fine but shooting in raw lets me adjust as needed. A friend used the light as a video light for a TG7 with a 52 mm to 67 mm adapter and said that for most nudibranchs the light was much easier to use than independent lights on arms. I wish it had more power, a 6000-lumen burst mode for this type of light would be awesome, but the current version is adequate for micro 4/3 shooters and awesome for the smaller sensor cameras like the TG series.

My experience with the MFO-1
Is this what Alex reported? I thought he was saying he asked Nauticam for magnification just less than the SMC. Confused I am. Bill
-
My experience with the MFO-1
Well I tried it with every macro lens that I know about and it works in the sense that you get some more magnification but as for edge aberration improvement, it is not obvious to me. BVA
-
My experience with the MFO-1
I just shot the MFO against some ISO targets. As far as I can tell for micro 4/3 (30 macro Oly, 30 macro Pany, 45 macro, 60 macro and 90 macro, there is no obvious increase in edge quality. Perhaps it has great use only in FF cameras. I talked to the Backscatter guys at the Long Beach scuba show and they said of course it is only for FF. I wish they told me that BEFORE I paid them for it. Bill

Macro gear with near unlimited budget
A lot depends on what you want to do with the images. If you are wanting to make 3 ft by 6 ft prints then more pixels be more better. For 16x20 inch prints, or smaller or for sharing online then u4/3 gets you more than enough to work with. Video capabilities are beyond my understanding but both Olympus and Panasonic shoot with good enough resolution unless your unlimited budget includes an imax theater in your garage. We just finished the scuba show in Long Beach where OCUPS had a booth. I did all the prints for the booth at 12 x 16 inches on metallic paper. We had shots from Z9, R5, D500 micro 4/3 TG7 and even some iPhone shots. Hard to tell which cameras made which pics. Bill

Rubber bumper on the bottom of housing
It is always interesting to ask the manufacturer but remember they were the ones that glued it on unsuccessfully 😃 Bill

Rubber bumper on the bottom of housing
I agree with E6000 or I have used this for gluing all sorts of things to housings and other toys. Bill

My experience with the MFO-1
I have shot it with the Olympus 30, 45 (Leica), 60 and 90 macro lenses on an OM-1. The focus speed for the 45 was improved, the other lenses not so much, maybe a little. I have struggled to demonstrate the improvement in IQ away from the center of the frame with any of these lenses. Maybe the micro 4/3 system is less bothered by flat port aberrations than full frame systems. The small increase in magnification is clear but for me at least shooting really small stuff, not so useful. Bill

Snoot in 3D printing
I really like the idea of a variable diaphragm but am too busy to try to make one myself. Cheers BVA

Home Insurance or Travel Insurance for camera gear
Long ago the DAN camera insurance was inexpensive and covered all kinds of loss. Every time a new camera came out there were a ton of "my camera/housing fell overboard and was lost" claims. After a couple of years of this camera loss was no longer covered. The DAN insurance used to let you decide how much to cover an item for, but I haven't looked for quite a while. Bill

Home Insurance or Travel Insurance for camera gear
Depends a lot on your home insurance. Many folks have reported that their homeowner's insurance premiums have increased after they made a dive housing claim. We live in Los Angeles and it our homeowner's rates went up since the fires. We self insure by creating a small ($15K) investment account that we keep mostly liquid. Over the last 10 years and 1500+ dives with no major user errors, we are quite a bit ahead of the game but also recognize that we are quite lucky. Bill
