Not real keen about the native base ISO of 250 (expandable to 125) considering with Z8 you get 64 and 32 and with A7R V 100 and 50 ISO. The ability to shoot HSS with all strobes is an advantage but most UW flashes don't flash at speeds reaching anywhere near say 1/10,000th sec. I am sure that global shutter will be the way of the new world as manufactures move away from mechanical shutter to all electronic otherwise we will be stuck in the rut of 1/200th sync speeds on full frame which can not be corrected with HSS strobes.

RC is Olympus/OM TTL which is different from some other TTL systems. What is innovative is the wireless flash trigger, no cables or fiber optic.

Depending on the camera being used many viewfinders have -4 to +3 built into the viewfinder on top of any additional changes that can be made with accessory viewfinders like 45 degree and 180. Like many my age and younger I have had cataract surgery in both eyes. I use disposable contact lenses and find that they work great underwater. They of course don't work for all vision problems but are worth consideration for these who can wear them.

The last time (Mid-Nov) I had a conversation with the owner of the company about the Apollo line I was told that the Apollo 33"s would arrive first followed by the 44"s and then the Apollo 28. Merlux hopes to have strobes into the hands by late Dec early to mid January. With full release in the first quarter of 2024. Regarding strobes for travel thesis a different strokes for different folks kind of issue. I have friends that have traveled for years with strobes like the Ikelite DS-161, ONEUW, Retra, Scubalamp, Seacam and more. Many take backup strobes or smaller strobes like the Backscatter MF-1/2 and Inon S-220's. If size V. guide number is important the MF-2's, S-220's and the coming Apollo 28 will be great choices. The Marelux Apollo line all have the same core features, the 33 & 44 models will use 3 X 18650 batteries while the 28 will use two 18650's. The 28 and 44 models will have two parallel flash tubes and the 33 will have three tubes. The 28 will not include a focusing light. I will post more including how the wireless Lumilink works.

Could this question be moved to the strobe section for others to see.

I am pleased to have been added to the Marelux management team as the Senior Advisor. Happy to field any equipment questions.

The site looks very nice and user friendly (especially it you are coming from wetpixel) may want to move the Retra strobe thread into the strobe section to keep things balanced.

Hi Eric, Great to see you involved with this site.

Nice to be piped aboard and happy to see sponsorship from our Marelux and UWP teams.

My name is Phil Rudin and looking forward to exchanging ideas and information on Waterpixels.
