I see more and more divers on S Florida boats with rebreathers. There are definite benefits, especially for us photographers. I appreciate how Dave also is clear about the prep and cleaning time required. The investment cost and training required is also important to factor in. If the steps are followed, rebreathers are safe and rewarding.

Yes, the 3rd column M3 Max 16/40c is what I am planning to buy, although not with 128GB / 8TB. It seems Thunderbolt 5 is a next gen advancement, but like clock speed between the M3 and M4, not a huge difference in real world application today.

Both tragic and scary. The only positive is there was no loss of life. As liveaboards continue to grow in popularity, hopefully a solution can be found to further protect them from fire.

Aside from the normal theoretical speed increase, Thunderbolt 5 seems to be the big advance for the M4s. Again, much of that is theoretical unless using dual 8K monitors and perhaps a few other minor options that may eventually become available.

Thanks for the feedback, Wolfgang. Any regrets making the switch to the HF-1s? I’m still not thrilled about the 21700 batteries or the heavier weight, but they seem to be the “best buy” among the strobes on the market today. The video light seems like it could add additional value for the occasional usage.

Congrats Dave!

Hi all, It’s about time to upgrade my computer. I currently have a 2020 16” MacBook Pro i9 that is fairly well loaded. I work primarily in Lightroom and Photoshop, but am considering adding Final Cut for some video. I use external SSDs for fast storage. It works well, but the new M processors are a leap forward, especially now at 3 or 4 generations later. I am considering a 16” MacBook Pro M3 Max (48GB, 14/40 core, 400 Gb/s bus speed) Thanks to the new M4s, the M3s have dropped in price. I’ve also found an Apple refurb Mac Studio M2 Ultra for the same price. No portability, but 800 Gb/s bus and 60 GPU cores vs 40. (More relevant for video) Here’s my question…Does anyone have an hard info on the new M4s compared to the M3 Max? I understand they’re literally only a few days old in the stores. I’ve been digging through YouTube, but all I have found has been pretty general in nature and just the overall specs. I know computers are always updating and we just have to jump on at some point, but as I don’t upgrade often and I’d like to try and get the best option I can. From what I’ve found so far, it doesn’t seem the M4s are noticeably faster in real work applications vs the M3 Max, but I could be missing something. Yes, the M4 does have Thunderbolt 5, vs TB 4 on the M3. And please, I am not interested in switching to a PC. I am bi-lingual in Mac and PC and have owned both. I will stick with Mac for now. Thanks in advance for any feedback you have on the great M3 / M4 question…. chip

I see both sides of the question. Currently, I am still using AAs for my Z-330s. I do like the idea of additional power standardized, quality Li-ons can produce, especially for more demanding hybrid options like the HF-1. I do have concerns about the number of cheap Li-ons that are not as stable. Yes, there are lower quality versions of everything, but there is a real risk with cheap Li-ons, especially on liveaboards and other dive boats. I’m sure solutions will be made, but it is still a bit of the Wild West for users that don’t invest in the quality, safer batteries. As with all technology, power demands continue to increase and Li-on is the direction at this point. Just my 2 cents…. (or now $14 factoring for inflation)

Nicely done; welcome back!

I'm in a similar situation and agree. If they're holding a solid charge, keep using them.

Wow - that is an incredible point! As a warm water diver, I never would have thought of such an issue. My biggest challenge is keep humidity from fogging up the lens. Just a little different. 😂 Thanks @Brandon Cole for the insight!

Here are some leaked images of the new toys…. https://www.sonyalpharumors.com/first-leaked-images-of-the-new-sony-a1ii-and-28-70mm-f-2-0-lens/?fbclid=IwY2xjawGSSn1leHRuA2FlbQIxMAABHRFF6VYmpNXtawrj65MJmVrux4tVKJVzTJLokN20tG7tNYczz7zYDO5AWQ_aem_zpuwWaN-iDD-l-tlhON84Q

Hi @Floris Bennema, Really good question. Great news that you haven’t had an issue. The WWL is a terrific design. And yes, it is mounted with the bayonet mount. The only thing to watch is because there is a thin layer of water between the flat port and WWL, it is possible to either get tiny air bubbles or even a pice of sand when entering. The camera’s autofocus can lock on to it, rather than the subject. In my experience it is rare, but it has happened. That’s why it’s strongly recommended to burp the lens once you’re stable in the water. This is normally not at all an issue. The only snag is if that rare occurrence happens when you most need it *not* to happen. That’s why some prefer a dry port to eliminate the possibility. With that said, the WWL is a terrific option and one I enjoy using, especially for lightweight travel.

I’ll add in my experience with the WWL vs WACP-C. Short answer, image quality is really the same. The WACP-C is a dry port which eliminates the need to ‘burp’ the lens. This can be critical when doing a quick entries with subjects such as whales or dolphins that require immediate photo engagement. I personally would not use the WWL in this situation. And yes, a dome with a 180 degree FoV fisheye will allow, and require, a closer interaction with a large subject. The 130 degree FoV with the WACP is still pretty impressive. The new FCP, despite its hefty price, would be an ideal tool as it allows zooming from 175 degrees to ~60 degrees and is a dry port. Another option is the Laowa 10mm 2.8 lens. It will work in a 140 or 230 dome and has a 130 FoV. This would give you the f/2.8 and other wide aperture options, if desired. Fortunately quality noise reduction software adds an additional tool to compensate for higher ISOs. Have an amazing time, and share some images!

I agree. While relatively limited, I foresee a greater demand for delivered high quality video. With that said, the cost of entry for this level of video production is higher and requires a greater skill set. And no, that is not at all diminishing the skill, talent, and vision required to produce high quality still images. There is simply ‘more’ of everything required for quality video production.

Interesting that the new a1 will use the a9III body. I do like the a7rV flippy screen design will be included for landscape usage. The new 28-70 looks very interesting for portrait work, especially the lighter weight. Will either of these specifically help in uw work? Possibly the new focus capabilities on the a1 II could be a win, but at a high cost. This new body + a Nauticam housing comes in at around $12,500, plus tax.

Passing on something I learned. If you do go to a Z8, or other high res camera, the focus point becomes extremely critical. Hi res files show incredible detail, which is awesome! They also show if the focus is not exactly right. Low res sensors (~24MP +/- or less) are much more forgiving. It took me a couple of dives to really master this. Just something to file away if you do move in that direction. 😃

I’m not a Nikon photog, but I agree to stay with what you all ready have. Sony does not seem to be a logic choice unless you simply want to move to Sony. Here are options I would offer: - House your Z6ii and get the new appropriate lenses/ports (least expensive) - The Z8 is pretty amazing! Sell your Z6 and go all-in with the Z8. A refurb could be a good option. Z8 gives the a7RV stiff competition. - Unless you absolutely want 180 fisheye, either WWL or WACP-C is terrific and quite versatile. WWL-1B or WWL-C are lower cost, whereas WACP-C is a dry lens. All are the same IQ. Best of luck! Let us know what you get. chip

Directly from Edward… “- Image quality is far better than shooting through a flat port. - Literally no noticeable focus hunting as the MFO converts the focus range of the camera lens. - (for Nikon Z105mm macro) focus range converted to 125mm-1100mm. - Slightly increases magnification at MFD (Nikon Z105mm macro ~1.2X; Canon RF100mm macro ~1.6X).” A solid overview of what to expect.

I'll 2nd the Zeiss Touit 50. I use it with my a1. I think it is fantastic for a medium range and blackwater. I use it in FF mode and simply crop the vignette in post rather than using in APS-C mode.

Thank you so much @Edward Lai for the information, and bringing this new product to life. And thank you @Alex_Mustard for your vision. It does in fact appear to be a game changing approach with terrific results! As someone who has taken a significant interest in macro photography, I see quite a number of scenarios where this will prove to be a tool leading to greater success. I can’t wait to add it to my tool kit.

100% agreed!!

Agreed! In a FB comment I found by Alex Tattersall, it appears we may have it right. He’s claiming a focus range on a Sony 90 to be about 2cm - 1m, with improved sharpness. If correct, that would fantastic! That said, I’m waiting for the official confirmation and hands on testing.

I've done some checking around today and details remain thin at the moment. The only thing confirmed is it is a stand alone lens, not used in conjunction with the SMC/CMC, which is what I figured. If it can reduce the MFD for a normal macro lens (i.e. Sony 90 w/ 28cm MFD) and still have a substantially longer focus range than an SMC/CMC, that would be quite useful. There have been plenty of times I wanted to get closer to the subject, but the MFD would not allow the lens to focus, while at the same time not wanting the extra magnification and super shallow DoF of the SMC/CMC. This would also match up with the name "Mid-Range Focus Optimizer" in macro terms. Again, this is just me interpreting the verbiage, but I have no idea if this is actually what it does. Guess we'll know more in the next 30-60 days....
