Regarding the Philippines airport restriction of no scuba equipment in carry on, it was unclear if this only meant regs or every piece of dive gear.
Are prescription masks, camera/housings, lenses, strobes, sola lights & dive computers still allowed in carry-on?
Taco, I would carry as much of your camera gear on as you can. It's not scuba equipment, it's just a nice protective case
Also your SOLA has lithium batteries. Best to take it in carry on, and also to set it up in travel mode, or at least, be 100% sure it's locked so it cannot turn on in flight.
For little things like dive computers, I have a travel vest, and all of our dive computers will fit in the pockets.
The way I look at it is, they don't want scuba in carry on because it's hefty and could be used as a weapon. But, any scuba gear aside from a prescription mask, is easily replaced or rented on site. Camera gear and expensive dive computers...I would be a little more than merely unhappy, to have lost in transit, or delayed...so as much as possible goes with my person, anything else goes in carry on, only backups for the backups, go in checked luggage. And if people ask, none of it is for scuba diving, it's for taking photos in the shower!
Carry‐On Luggage Restriction: Effective July 1, 2015
Philippines Office for Transportation Security has issued new rules that include ‘Scuba Diving Equipment’ (including regulators) on the list of blunt instruments that are not to be in carryon/cabin baggage on flights originating within the Philippines. Please ensure that all scuba equipment is secured within checked‐in baggage on all domestic flights and on all departing international flights.

Much may be subject to the interpretation of the agent you are dealing with at the moment.
If you want to risk carrying on your computers, that's up to you. It is their country & airline and your arguments could fall on deaf ears.
You should not have a problem with your general camera equipment i.e. camera, housing, strobes as long as you stay within the weight limit. I would put in checked luggage the metal arms, trays and such that they may con screwed as being used as a weapon. Any items with lithium batteries must be in your carry on or person and in individual cases for back up batteries. Make sure lights are in locked positions and terminals on strobes covered.
If you are still unsure, I recommended contacting the airline.
Later this evening, we will send out an additional PDF document we received showing what may & may not be hand carried. Here's also the link to the airline's page for additional info.
