@ Lewis88, Good point. And in all fairness, not an unreasonable investment... if I didn't change my cameras every 50 to 60 dives. my bad on that score. But at least you can keep the ports, so maybe I should dive in. @'121, mmm, back to school... thanks!

As valid as all the above comments are, I am still using the VPS-100 system. And until I have a better system, I replace the plug with due care - but bumps happen and do worry me. I have done 45 dives with the '100 so far so lucky. The pump is absolute crap, a silly joke compared to the cheap and available alternates out there so that is the first thing to change. Mine might be an exception but it takes 45 pumps to evacuate - I lose count using a dome. A SeaLife generic pump takes 5 or 6 pumps. And my battery died after 5 uses, so carry spares.

Thanks, I may go that route ... the two are both around the same price here in Toronto, between 200 to 300 CDN so once I understand the hardware, I can go get one. I understand the Sigma allows for firmware upgrades - for what, I have no clue, so maybe that would be a better bet.

Oh, OK then - I was under the assumption that when movement and focus is an issue you just set at infinity-1 and with a 7 or 8mm all will be in focus - but I have no experience yet - here to get up to speed. I was refereing to the Samyang the fits the small 4" domes in the 'frog housings so I figured Nauti would have an option.

I am kicking around the options for fisheyes and it is looking like I will be needing a Canon to Sony E adapter for my Sony a6400 (maybe upgrading to a6700 but unlikely to FF). I am fuddled with the various Metabones models. There is the Series 5(V) as well as the 'Ultra' as well as previous generations, but is there a difference or 'best choice' for underwater use? I will probably end up with a Tokina or Canon Wide FE zoom but I doubt I will be zooming much and would probably be happy with a Prime. I will be putting it a a Salted Line with 6" dome. Thanks for any help. Simon

The Tokina seems to be a legend in the price point, but there seem to be a number of fixed focals FE's at or around 10mm that might not require converters for Sony use. Why are these mostly never mentioned?

Encouraging idea. Here in Toronto we passed a ban on Shark Fin Soup - it was overturned for being culturally racist. 🙄

Great, thanks for sharing! quite liked the soft backgrounds in many of the sequences.

Wow, you sure got friendly with that octopus on that Cozumel 6-2019 dive! Great shots!

There seem to be a lot of comments, claims and criticisms regarding various strobe/snoot assemblies which are all good fun but don't always tally with my observations. I am wondering if there are any testing standards or best practices for reviewing these packages - that ideally one might be able to replicate to confirm some level of accuracy. I think I am reasonably aware of the myriad of variables that come up but it would help me understand the real 'illumination based' / lighting through-put advantages of one system compared to another - in actual numbers - leaving ergonomics and cost benefits to the talking heads. Has this been done or listed somewhere?, as I have looked about and have not found anything. This sort of data would be very persuasive (for me at least) to meaningfully consider my possible snoot futures. Simon

Hi there, my name is Simon, I was introduced to this site from WetPixel (polyroly) and signed up as I always like new viewpoints. I am from the snowy north but only (so far) dive in the sunny south - so no dry suit experience yet. We have just over 300 dives, recreational depth and mostly land based but also on a couple of liveaboards. I try to keep my kit small due to travel baggage limits and I am always trying to make my kit smaller - it gets bigger. I am using a Sony a6400 and a SaltedLine housing mostly using the 90 Macro, with a single Z330 and a self designed and printed Snoot that incorporates both Optical and Fiber interfaces. DIY is a sickness. Underwater, I love finding small worlds and so I love Macro - also why I love photographing mushrooms and lichens on our forest walks. I am drawn to the inconspicuous subjects. Microscopic dioramas cause me to smile.
