No differences at all as summarized in the last post. With the Backscatter version you have the additional option of using their filters.

Don't mess with the shutter speed on Gopros

Yes, long story short, it's not a matter of fisheye or rectilinear lens but just a matter of actual FOV. The most critical camera movements are tilt and pan. Ciao

Welcome aboard Jim! Plenty of living critters here 😄

WB magics!

Welcome back Stephen!

I couldn't find anything. Better ask to Isotta.

Good question. I stick (almost) to rectilinear. In your shots the fisheye works because as Chris wrote, with the crop you are cutting most of the fisheye effect. Moreover the motion is parallel to the reef (trucking shot) and there are no subjects crossing the frame. The shape of the reef confuses or hides the horizon distortion. In documentaries it is used in just such cases: a bird's eye view of a reef where the particular perspective given by the fisheye communicates to the viewer the vastness and infinity with a frontal movement (dolly shot) as in your second case. The problems come when you have subjects crossing the frame or staying on the edges. The distortion introduced by the fisheye is not to say annoying but alienating. Imagine doing a rotation on yourself (panning shot) to follow a fish while keeping the bottom reef framed. The movement would look unnatural. In these cases it is more a matter of FOV and even extreme rectilinear lenses suffer from the same flaw. However, I have used the fisheye several times and don't mind it, knowing its characteristics you can exploit it. I still use the WWL-1B which has a slight distortion typical of fisheye. Often, on panning shots, I zoom in slightly to avoid the distortion. Once I forgot the dome for 7-14 at home and saved myself with an 8mm fisheye. Too bad they were all wreck dives. I won't tell you how the gun barrels came out! 😀 But it was that or nothing...

That type of booklet closure is subject to those problems. When you close the housing pay attention to the cleanliness of the o-ring and close very precisely checking that the o-ring is not pinched. Especially in the part near the hinge. When it is closed, spend a second of time checking that the o-ring is positioned correctly.

I hear clicks on the keyboards of the DIY forum already 😉

Do you have harmless animals in Australia? 😄

Nice video indeed and amazing dive spot! I hope to dive there soon.

Give us some feedback when arrives with some photos and of course some uw clips when you will use it 🙂

I think the suggestions given from the op are a good start. Regarding WB I'd go for "native" as @bghazzal suggested. Auto wb on Gopro is really unpredictable. Of course you are forced to do some color correction during edit but for uw work it's a must. You are in a PAL country so 50p is mandatory. With the AOI lens you don't have corners problem so wide FOV all the life. If you are filming in the Med you need a couple of good lights. Give a look at the YouTube channel of our member @jpiovano He has several good examples of Gopro in the Med and IIRC he is using an AOI lens. Maybe he can share his settings. Last but not the least: Gopros are tiny weightless cameras so a perfect trim is paramount and it's difficult to achieve. Often I see Gopro kit unmanageable underwater. Weight all unbalanced to the lights. With such a setup it's impossible to get steady shots.

Welcome to Waterpixels! R1! Great investment. Is there an housing already?

Welcome aboard!

I can confirm that the lens is heavy and wouldn't be safe on a flip.

Backscatter version works perfectly in 16:9 or 9:16. The op was experiencing vignetting using the full sensor readout 8:7. In this mode both Backscatter and AOI vignettes The Backscatter version gives you the option to use their filters.

Link to your post added. Could you link a printing file? Thanks a lot

Hi Ozzie, Welcome to the "other side"

Hello eLzUb Nice to have you onboard!

Hi Gmsalterego, Welcome to the forum. This is a section for member introductions at their first message. Let's tell us something about your passion first! Ciao

It depends... 60 and 30mm gives you the full macro experience 🙂 Oly 60mm is the "classic" M43 macro lens. Pana 30mm is a good lens but it gets the maximum magnification very close to the lens, then you have the port and optionally the CMC-1. I guess it would be a nightmare taking photos with that lens and the diopter. Maybe someone who use it can give you a more precise feedback. 12-60 is a versatile lens for medium and close shots. With the CMC-1 on a flip holder you could get the best of the two worlds in the same dive. But keep in mind that shooting with a diopter is not like shooting with a macro lens. Sometime I use the 14-42mm and CMC-2 I think the experience would similar but more extreme. For pure macro I use the Pana 45mm and optionally the CMC-2 but I miss other two hands and another camera with a WA lens in the same dive. Maybe in another life 😉 P.S It's a shame we don't have feedbacks from @Aquatica

Yes, basically with the Backscatter version you have two filter options. Backscatter slide in filters and in the future the "bghazzal ultimate gel filters" 😜

I have not found those models among their lights sold here in Italy. I think the acronyms change often. Yes, a good video light should not have sharp edges. Lumens on lights in this price range are a lottery so it's only worth a practical test comparing them to other lights we trust. The important thing is that they can illuminate the scene in WA footage with your gopro.
