You can contact Saga Dive, as they can mill one for either a Seacam or Subal type 4 to Nauticam N120. They did Seacam to N120 for me last year.

That whole setup was sold back in January.

I have just started using a Nauticam MFO-3 mounted with a flip adapter with a Nikon Z8 and Nikon Z 105mm f/2.8 VR S Macro Lens and found that it worked surprisingly well. The best testament to just how well it performed was during two blackwater dives of West Palm Beach, FL. Blackwater photography, as some of you know can be in creditably challenging. For me, the greatest test came when we found a small paper nautilus on the second night. Although the little sucker never stop moving except to rest on one diver’s fingertip, I came away with more than a five dozen tack sharp images with just a handful of throwaways where the focus didn’t nail. More I shoot with this lens, the more I like.

As I have listed earlier, the 21700 Li-Ion rechargeable batteries that I am using for my two new Retra Maxi Strobes is comprised of six 3.6V model Nitecores. Four consist of the NL2160HP models which boasts a capacity of 6000mAh at 21.6Wh, whereas the 2 Nitecore NL2153 models feature 5300mAh with a 19.08 Wh rating. In addition to them, the 21700’s provided with both my Dive Rite CX2 light and Kraken Sports Hydra 1800+WSR focus light are also 3.6V 5000mAh models with 18Wh rating. All feature a continuous 20A to 25A discharge current specifically designed for high-drain devices like powerful flashlights and flash systems. Based on that and what others like Chris Ross, Dave Hicks, and Backscatter have sited to use with Backscatter HF-1 and Retra’s Maxi pretty much boils down to 20A 3.6V 5000mAh model 21700 with 18Wh rating. The only question from there is why would you want or need with 21700 with a lower amperage for a HF-1?

That is very true TimG, provided you have the right credit score and willingness/funds to handle the membership fees. Most of my CC are made of metal, aluminum mostly, but not titanium. My income is not high enough to afford one yet.

Oh, the excess, excess baggage fees. I can detect the smell of a melting credit card all the way here.

Sea & Sea 77mm Internal Correction Lens has been Sold.

Dropping the price to $700.

The Retra Pro Max strobes have been purchased by John Melendez in WA. I still have the one Prime available.

This is a matched pair of Retra Pro Max I (not the Pro Max II models) underwater flash units with Booster Extended Battery Packs. The first-generation Pro Max models pack 140Ws of power providing fantastic lighting for both wide angle and macro photography. The feature that makes the Pro Max series a top-tier underwater flash, is Retra’s famed circler flash tube, redesigned battery compartment and backlit LCD display that shows you all the necessary information in one spot. The battery compartment allows the use of 4 AA Batteries with the standard battery door or double the number AA batteries from 4 to 8 via Retra’s Battery Booster. The Booster is a single piece battery door that allows 4 additional AA batteries to be placed internally in the flash to double the shooting the duration of the Flash unit. Among the list features – TTL and High-Speed Sync (HSS), the Pro Max include a built-in water leakage detection in the battery compartment. Like all Retra flashes, the Pro Max features Fiber Optic Connection and accepts all Retra series Reduction Rings / Beam restrictors and Wide-Angle Diffusers as well as Retra’s Light Shaping Devices with the Retra mount.

The Prime is Retra’s underwater flash featuring a complete, unbroken circular flash tube generating a full 130-degree beam spread without the aid of a detachable diffuser. The quality and consistency of the light for shooting wide-angle is ideal adding color temperature in the 4900° Kelvin range rendered a warmer white to the lighter color regions on subjects like sharks.
