Hi Odyssea! A warm welcome to Waterpixels. Great to have you with us. We hope you enjoy the forum. Best wishes Tim

The only thing, for me, to bear in mind with the 8-15 is that it hardly merits being considered as a zoom. It’s really two lenses: a 15mm FE; and an 8mm lens that produces a circular image. The later is interesting but has very limited use. There’s precious little useable zoom between the two. If you add a 1.4 TC it becomes much more interesting as a lens on FF. Used on an APS-C body it’s a great with or without a TC.

Hey guys, I just created my profile after lurking for a while. I was quite active in the other -now deceased- forum, as well as scubaboard. Glad to be here to learn and hopefully contribute. Cheers!

@monikatheplant I don't get here as often as I used to... And yes, I still have the AX700 Gates housing if you're interested. It has absolutely no problem with overheating. Probably have to get it out and take some pictures to post in the marketplace. Tom

When I eventually "retire" I plan to set up a small not-for-profit in the south east of Mindanao that will oeprate a small diving resort that has access to good shore diving, the profits from which will be used to help build emergency response capability and disaster resiliance in the area - there is virtually nothing of either there at the moment. A whole series of coastal communities where the nearest fire truck has a three hour response time to get there says "opportunity for improvement", and given the frequent floods, landslides and earthquakes I'm thinking that something like a skidsteer loader etc would be a useful addition for the communities, as would a stock of sandbags etc.

I would also probably use this camera mainly underwater, so I agree, that this extra lens means that underwater use was seriously considered and designed.

At least one person likes the Tamron 17-28: https://interceptor121.com/2024/04/13/tamron-17-28-f2-8-for-underwater-photography-review/

Hard to beat a 8-15 behind the 140mm dome like Dave Hicks uses. If there is a lens combo that works for Nikon FF he's probably tried it. Both those use cases want an AF lens.

There’s been discussion in the past about using these lenses and it’s worth doing a search. I do remember reading about issues with the 14-24. I’m sure you’re right that all three need probably 230-sized domes.

In addition to using professional system cameras like EOS 5D Mark IV etc., I have used and enjoyed different GoPro versions for many above-water excursions over the years. However, when it comes to underwater photography I am uncertain as to what photo quality, resolution and light sensitivity to expect. What are your experiences, and which GoPro versions could you recommend for those curious about using GoPro for UW?

Any Nikon ff z-shooters that have tried it and can share experiences?

Nice, the focus peaking shows it is sharper and the AF will work better with a sharper image - it should not be any better than the bare lens in air, but it shows the level of image degradation of a 60mm FF equiv macro lens through a flat port.

Dave, Are the 14-24 or 14-30 or 17-28 of much use underwater? I suspect that they all have the drawback of needing large dome ports.

That (replaceable) lenses is actually a good thing. It means that when they designed the underwater use was in mind and it wasn't just an afterthought. With Nauticam housing your lenses get replaced too although they are like built into the housing :-). This and low light performance differences made me to order one. And if it comes till next Friday I put it to test in Maldives :-)

SMC3 is basically new version of SMC1. Just bit more smaller and lightweight.

I think the red filter + ambient lights are the game changer here, right?

Cheers Phil, looks like I can cross a few off the list! To answer @Grantmac 's question - fullframe macro and CFWA - Nikon Z.

Greetings from OM Digital Solutions. We are contacting you to follow up on our phone conversation regarding the TG-7 underwater accessories. FD-1 (Flash Diffuser): Can be mounted, removed, and used underwater without any limitations. It is the ideal accessory for underwater macro lighting, effectively directing the built-in flash light. CLA-T01 (Adaptor Ring): Can be changed underwater without restrictions. It is suitable for attaching underwater filters or converter lenses (such as the FCON-T01 and FCON-T02 fisheye lenses). LG-1 (LED Light Guide): Not suitable for underwater use. Water fills the optical channel of the accessory, altering refraction and preventing the correct diffusion of the LED light. LB-T01 (Lens Barrier): Not recommended for use underwater. Water and small air bubbles become trapped in the rotating blade mechanism and in front of the lens's front element, impairing image quality and causing fog or spots in photographs.

I am using my 90mm with SMC1. Just got back from Lembeh. Would users recommend adding the SMC3 for super macro?

I'm just saying if we knew what housing, body and intended image projection we're dealing with it would drive the conversation into more productive directions.

The OP specifically ask about the Laowa 15mm for CFWA. If you are not aware this is a full frame lens. Nikonos lenses were also mentioned and they are full frame lenses. In addition for Nikonos lenses you need an adapter only made by Nauticam for sony full frame cameras. cameras. The images were taken with the AstrHori in a Marelux 140mm dome port which is simply a fact, this is a port that can also be used on Nauticam and several brands. If you would like to start a thread regarding unsupported M4/3 lenses I would be happy to help with that. Housing brand has little to do with camera/lens combos as most work in many different housings with proper extensions.

I suggest getting both! These are both really great lens setups. While there is some overlap in range they both have unique properties and use cases. With the 8-15 under a 140mm dome, there size is also fairly similar. The WWL-C with 24-50 is a great all around setup. Many divers would be happy with this as their only lens. It handles standard wide angle down to near-macro subjects. Very versatile and high quality. (don't consider the 24-50 without the WWL-C) It is also easy to shoot and master. The 8-15 fisheye and 140mm dome are possibly the highest quality image you can get in a wide angle. However it is more difficult to shoot and light your subjects effectively. It can shoot an entire Humpback Whale from 3 feet range, or a 3 inch fish from Zero inch ranges. Extremely wide to Close Focus Wide Angle small subjects. This is a more expensive lens and will take some learning, large strobes, and investment of time to master.
