Yes, the Maxi is bigger but not all that much. About 8mm more in diameter and 27mm longer. Honestly, I can imaging you would notice in active use. And there is no booster to bulk up the Maxi, where the Pro Max all be requires the booster for decent battery life. Yes, video light is optional and will save $200usd. It's a nice to have feature and the strobe has power to spare for the 5000 lumen light.

Consider the Retra Maxi strobe, not the Pro Max. It's brighter, faster, longer battery life, and include excellent video lights. I am not sure who the Pro Max is for, but it is not the best Retra anymore for most people.

The WWL-C is so good, that paying extra for a Nauticam system is well worth it. Some other brands might be adaptable, but the Nikon 24-50 / WWL-C combo is a killer.

If you like nikon lens options, consider a used Z8 or even the Z5-II. A used D850 system would be a great option. Still excellent but old enough for great discounts. I've not held a Z6, but perhaps it will grow on you. Generally the screens stay closed and one rarely touches them, for what it is worth.

You can use the Nikon port60 for the 60mm lens and add a 20mm extension to shoot the z105mm lens. Two lenses, one port. Both lenses are excellent and the performance on a Z8, Z5II, Z6III, etc are fantastic. Even the larger combo of the Nikon z105mm is MUCH smaller (shorter) than the Sony with a 100mm lens/port. Add an MFO3 to the Sony 100 and its seriously big unit.

Someone on Facebook / Alex Mustard group just asked a similar question. I'll share the same answer I posted there: The MFO-3 only exists because Sony doesn't have a decent lens in the 60mm range. Nikon has an excellent 60mm, so MFO-3 seems like a superfluous product for that system. Instead, using an MFO-1 and SMC-3 gives you a huge range paired with the native 60mm. I'd rather shoot a 60mm and use a diopter than use a 105mm and then "shorten" it with a hack like the MFO-3.

Another 8-15 +1.4tc shot that I really like from God's Pocket. A close-focus-wide-angle shot of a decorator crab on a sponge. Decorator crabs have a lot of personality and cover themselves is clever ways to match their environment. These crabs are specially tailoring their camouflage to incorporate parts of the sponges they are living on.

The FoV is pretty good. I really like the 15mm native field, and was hoping to get just a bit more reach for scenarios where that might be desirable. Sharks, etc where you might not get to point blank range. That is where the WWL-C excels with it's near-macro to wide angle range. The 1.4tc gives the 8-15mm a taste of that flexibility. I don't see a huge compromise in sharpness so far, but will take a few more days of images to decide.

Today I shot the Nikon 8-15 fisheye + 1.4tc (old kenko) behind a 140mm dome using a 3d printed 40mm port extension and custom zoom gear. I think it worked very well. The "full" field seems to be at 12mm. A few shots were at 11mm and have very slight clipping. Nikon Z8 with Retra Maxi strobes 12mm full field shots: 15mm "bonus 1.4x zoom" shot:

yes, that one. It was my very first 3d printed original design.

I made a preflash button blocker for Inon flashes. I made Retra Maxi knob replacements for the same reason. The knobs are the same shape and i wanted them to feel distinct.

I know that @Kiliii Yuyan is using this lens on a Nauticam housing. He may have some details about what port extension is working best.

Are you going to dive your printed port extension? I recently printed made a Nauticam n120 extension of 40mm and did a successful test dive to 106ft with it. I plan to shoot it this week with my 8-15+1.4tc.

The low tech solution would be to use so Sugru rubber putty to modify your knobs

Super. Lets see a photo of your rig with the shiny new fiber!
