Beginner question about wet optics and optical zoom
If I read this right, Gary, you want to be able to stand further back from your subject? So getting the same distance from your subject as oyu did with the 105mm If that's the case, you could perhaps add a 1.4 or 2.0 teleconverter (TC)? this would increase the magnification of your 18-45mm lens by either 1.4x or 2x. You'd lose a bit of sharpness but arguably not that much and a slight loss of light. You could increase the ISO a little to compensate or use a slightly slower shutter speed or open the aperture. So there are options. You'd also need an extension ring to house the width of the TC - 20mm for, say, the Kenko 1.4 TC which is popular underwater. Generally a diopter allows closer focussing rather than necessarily magnfication

new Retra strobe the Pro Max II
Thanks Oskar Can you just confirm the fit details for the bumpers and the neoprene jackets? Are they the same size as for the Pro Max 1?

Help Choosing Underwater Zoom: Tamron 17-50 vs Sony 20-70 vs Sony 16-35 PZ
That's always the case no matter how many or what lenses you have. It goes to the heart of what I often bang on about. You have to decide before you dive what you want to photograph and go equipped for that. That, to me, is where it does wrong with a mid-zoom: neither here nor there. It's not just the equipment but the mindset too. Go set up for macro and you hunt for macro subjects and their frames. Fisheye and you're hunting wide-angle, looking for sunballs etc; mid-zoom - errrr, heaven knows - bit of this, bit of that, a lot of nothing......

Help Choosing Underwater Zoom: Tamron 17-50 vs Sony 20-70 vs Sony 16-35 PZ
If you're looking for a bit more "reach" with the fisheye, does the Sigma 15mm work with a Kenko 1.4TC? Hmmmm, not sure but others will have view. I think it does. That'd be a cheap way of increasing your options. You'd only need the TC and a 20mm extension.

Help Choosing Underwater Zoom: Tamron 17-50 vs Sony 20-70 vs Sony 16-35 PZ
Hey dimi I use a fisheye for almost everything wide-angle. I had the Signa 15mm for my D800 and loved it. No, I wouldn’t go with the 20-70. If you want a topside zoom - which is a no-brainer - I’d go with the 28-200. Even better a 24-200 if you can. I got the Nikkor 24-200 topside and love it. It’d be perfect I’d think for topside Galapagos. Useless underwater!

UWTechnics Sony Trigger - strange request 🙂
i can't help with specific dimensions, but the spacers with my UWT board (for a Subal housing) can be no more than 3mm thick. They are not threaded and, as you say, they are just to help the board sit evenly on the housing and avoid contact between any of the board components/electronics and the housing. I think you could almost fabricate a couple from cardboard.

Retra Flash Pro Max II
Retra have announced the launch of the new Retra Flash Pro Max II, which they describe as their most advanced professional strobe to date. "Built on five generations of innovation and field-proven performance, the Pro Max II redefines what’s possible in underwater lighting—delivering Li-ion-level performance using safe and widely available NiMh batteries." "With an impressive 190Ws of flash power, the Pro Max II produces 65% more actual light output compared to its predecessor—all while maintaining the same compact size and weight. This significant leap in brightness is achieved through a redesigned reflector, optimized power handling, and an improved triggering system that channels more energy into light rather than heat. Whether you're shooting fast-paced action or intricate macro scenes, you’ll appreciate the 25% faster recycle times and the ability to shoot up to 2000 flashes at 25% power using the 8×AA configuration. It even supports continuous shooting up to 60 frames per second on low power settings." Full details can be found here: Retra UWTRetra Flash Pro Max IIThe Retra Flash Pro Max II is our fifth-generation professional underwater strobe, engineered to push the boundaries of lighting performance.

Help Choosing Underwater Zoom: Tamron 17-50 vs Sony 20-70 vs Sony 16-35 PZ
Hey dimsak I'm sure you'll get lots of great advice on the qualities of each. I'd like to give you a different perspective: My experience has been that a fisheye and a macro are the essentials - anything else is marginal and I'm not convinced by the need for something mid-range. The fisheye covers the vast majority of wide-angle stuff unless you are determined to use a rectilinear lens. Then a macro lens covers the majority of the fish portrait and macro type images. You have the excellent Sigma 15mm; and are planning the macro. The only potential use for a mid-range, for me, is maybe pelagic that won't come close. But even then, really marginal use I've found it better to plan the dive setup for macro or fisheye and then search for subjects that fit that criteria. Mid-range is very much neither here nor there. My advice: save your cash.

new Retra strobe the Pro Max II
I know we've been over the ground before, but I find the Retras with, as necessary, the Booster work really well with AAs. Taking 32 AA batteries is no big deal when you consider just how much gear we are lugging around. And, worst comes to the worst with chargers, AAs are so easily obtainable. I agree with Oskar.

Changing viewfinder
Here's pic of the tool that works well for the Subal viewfinder. You can see the two pins that go into the two holes on the retaining ring. I'd imagine other viewfinders have a broadly similar arrangement.

new Retra strobe the Pro Max II
No, you're not missing anything. The USD price is the tax-free price that Retra charge. On the website it explains that import taxes and the like are not included in the price; and that for EU sales, VAT is added at checkout. God knows what the US duties/taxes might be. That seems to vary by the day. Or hour. I guess that will be charged by the US-based handling agent for the shipper: DHL usually for Retra, I think

Home Insurance or Travel Insurance for camera gear
Yeah, as Bill suggests, a lot depends on where you live. Home insurance can work and, for the UK, there is a specialist dive gear insurer - but rates are pricey. I'd suggest talking to your home insurer and get a clear steer on whether dive gear - and what elements of it - would be covered by a home policy or by an add-on policy or addition.

Changing viewfinder
Hi canislupus I use a Subal 45-degree viewfinder on a Subal housing with a D500. On that system there is a threaded ring which screws on to the viewfinder when it’s pushed into the housing. A pair of o-rings on the part of the viewfinder that pushes through the housing provides the water seal. It’s very simple but effective. I do remove the viewfinder for traveling as it’s otherwise an awkward shape in my Pelican case. It’s a 2-3 minute job to install or remove it using a very simple tool. Once you’ve done it once or twice, I’m sure you’ll be comfortable with the process.

Sure, it was the “automatic “ I was thinking of.

EV steps on camera and strobes
I can't say I've heard of a camera adjusting aperture in coordination with a flash EV setting other than, I guess if you use TTL and Auto settings. But would you really want to do that? I would have thought it simpler and more controllable just to use the aperture setting as part of the Manual exposure to mange DOF and then the strobe setting dial to increase or decrease power.

Looking for input on small strobe for a lightweight rig
John, for the relatively small difference in size compared to the whole setup, why not use just one Retra?
