It should work in any hotshoe, however that battery compartment is probably too large for a m4/3 housing, you should get a CR2450 powered one.

Subscribed to the topic! Although I'd stick to manual mode with my gx80, because of its slow default sync speed.

I was briefly considering the swap to the a7rII from olympus, but adding up all factors, including my laziness I rather downscaled the camera towards the r100iv . If I am "finished" with the rx100iv, I'll most likely baptize my topside GX80 or its successor m43. I simply can't justify the added ~2kg weight and 2+k$ cost of a FF housing, I see the bulk and money costs better invested in strobes/lighting tech (I have 2 subtronic nova's waiting for optical conversion). True, this comes down to what am I shooting: mostly wide angle stuff, very little macro.

I came across a store review of the WWL-1 and an interesting piece of glass showed up there: the Dyron SWAL13. Has anyone tried this, and its narrower siblings on a m43 camera? First round I'd try it on my NA-RX100iv for 4k video shooting, as a cheap alternative to the WWL-1.

I feel what you mean:) I have normally 2 trips a year, a serious one alone and a light one with my family: on the latter I definitely don't bring my full setup. Also on the "serious" trip I do the first few diving days without any camera to enjoy the ride. I don't have any obligations to deliver, it is a hobby and it is 100% my decision how much time I assign for it. Pro's don't always dive with the camera, they often check the site first.

With the emerge of the WWL-1, I am leaning towards the wet-lenses. The wwl-1 specifically is not perfect (heavy and can't be selected rectilinear as the optically inferior inon h100), but I hope there will be serious development efforts here.

Unfortunately you're right . Otherwise I'd consider upgrading my na-rx100iv setup, but my GAS healed enough to dismiss a 6k$ investment (camera, housing, ports...).

I would also consider using a standard zoom and the WWL-1.

I see Unfortunately no one shared a picture on the housing:(. However, it's not too difficult to fit an LED, a small circuit and a coin battery with a little DIY.

In the GX80/85 housings it certainly does, question is if it can be pushed into an old GX7 housing

Everything can be "good enough". You won't need an IBIS providing 2sec exposures if the subject moves in <1/4sec. Unless you shoot chess pieces, there will be movement in the picture. Oly maxed out IBIS, Panny is very close with the current GX85, it's time to focus on other aspects, like c-AF, video codec, etc.

Olympus is a new player in the video field, they were lagging miles behind Panasonic - a setback, which is difficult to correct in a single move. PRO video is not just an Mbps and a resolution number, it is about pixel (over)sampling, sensor performance (rolling shutter, overheating), codec, clean 10bit HDMI out, video-friendly features like Log, Zebra, easy change of settings while shooting,

I just bought a GX80 (EU version of GX85/GX7mkII) for topside and tested: you can sync up to 1/320 with a manual flash (e.g an LED strobe trigger)! 1/250 is perfectly clear, 1/320 looses a roughly 5% band on the top of the image - no concern, if the target you want to light up is below in the "90% portion" of the image.

200 is the lowest native setting, however extending it to 80/100 brings native-like real advantage (=linear behavior) in noise and dynamic range. mk5 is not out yet, I am wondering if it is coming this year after the Kumamoto earthquake. To bring a real punch, they have to sort out the overheating issue (quite "burning", I had problems in the red sea this february, even in the all-metal nauticam case) and show some performance achievement. Former is easy, read a mod on dpreview that (voiding your warranty) you can DIY (I'll definitely do it before the "shooting season" around christmas). Latter is tricky, the RX100iv has a state-of-art sensor with full readout, I don't expect any meaningful upgrade in <2 years.

Nauticam's WWL-1 is your best bet for WA, just search around wetpixel (I don't have one yet but its on the list). For Macro you have multiple options, I personally use a ucl-165.
