  1. I cannot say how the zuiko 9-18mm performs behind the 100 port, but we have the lens. My wife was using it first behind a flat port (also recommended as a solution by Olympus) and now is using it behind the Zen DP170 (170 mm) port. The IQ is no comparison, flat port @9mm is ugly... Wolfgang
  2. The major difference in weight/size is for wide angle. When using rectilinear WA lenses and a small sensor (MFT) a 180mm dome is o.k. with e.g. Pana 8-18mm, while for FF you will want at least 230mm dome, better one of the monstrous WACP's. Similar with Zoom fisheye lenses: I use the Canon 8-15mm with 1x adapter and 140mm dome on my MFT camera and it covers all my WA desires in very high quality. With FF sensor the same lens can be used with same dome and the rig would be very similar in size/weight, but the angle of view would be either circular fisheye or 180o diagonal fisheye, but nor narrower angles... For Macro I found out that, surprisingly and unexpectedly for me, there is also a hughe weight/size difference between MFT and FF. In addition to the Panasonic 45mm and Zuiko 60mm macros, I also use occasionally the Canon 100mm IS Macro lens with 0.71x or 1x adapter on MFT. While the Canon 100mm would be close to the Pana 45mm, when used on FF camera, this lens and the corresponding dome is a monster, when compared to the MFT lenses and the N85 port. The Canon on my MFT camera is the biggest rig version I have so far, even bigger and heavier than the WA configurations (With, e.g. a Canon R camera size/weight would be comparable at twice the angle of view. In case you are interested, I can make photos tomorrow, but I have to leave now towards Vienna)... I am squinting towards a FF system, because of the good low light abilities, sharpness, dynamic range and 14 bit resolution (postprocessing!), but the WA options scare me off, so far... Wolfgang
  3. Hi strandbygaard, Here a WeeFine (=Kraken) retailer from within EU (Vienna): https://www.unterwasserkamera.at/shop/catalog/en/product_info.php?info=p6960_weefine-wf057-3000-smart-fokus-lampe-mit-strobe-und-strobe-off-funktion.html I have the WeeFine 2300 Smartfocus lamp and it is enough as main light for day and night. Good for approx. 45' to 1h of diving and much longer, when switched to less power and 100% only when needed... Unless you are a cavediver, who needs strong light for many hours, you do not need accu canisters in these days... Wolfgang
  4. The optimum for UW are lenses with internal zooming, i.e. lenses that stay constant in length when zooming in and out (e.g. Panasonic 7-14mm; an example of exteranl zooming is e.g. Zuiko 9-18mm). I personally do not know about internal vs. external zoom for every lens. A table that shows which type of zoom for each lens and hwat length difference between the extremes, will be very useful, at least to me... Wolfgang
  5. Hi Spitfire, I had a similar situation in February 2019, when departing from Hurghada airport (Egypt). I had 16 AA Eneloops in boxes plus other accus in my photorucksack when the safety officer told me they needed to be in the check in lugagge and he has to confiscate them now (the check in lugagge was already on its way). I started to contradict and a long negotiation started. Inbetween he repeatedly was murmuring something like "bakschisch". Just because of the principle I did not give him a single cent (I would not have left without my accus and was ready to give the Austrian embassy a phonecall). At the end he gave up. In the meantime my wife (also with photorucksack) was checked by another safety officer, no issues with her accus, but he gave her a lengthy talk about the quality of Egyptian men and offered her the possibility to marry him (unfortunaly for him there was no demand)... => These IATA regulations are nice (and very lengthy as the 27 page long paper just on Li accus cited above) but of little help, since the personell usually does not know them. Even here in the Wetpixel forum our experts have different shools of thought how to carry accus along. I think it is advisable to carry three copies of the regulations of the specific airline along (these people have the habit to grasp them and not give them back), just to be on the safe side... Wolfgang
  6. I am not very familiar with compact cameras, but in autumn an a dive Safari I met an elderly but in good shape photographer, who had a small Panasonic MFT camera (I think it was GX7, GX8 or similar) in Nauticam housing with standard zoom lens and port. He used it together with a wet wideangle lens (probably he also has a wet diopter for macro), just like a compact camera setup is used. His setup was visibly smaller than the setup of another peer potographer on board, who was using a Sony RX100 in Nauticam housing. This way you could have a light setup, but with a better sensor. Over the water you could continue to use your interchangeable lenses... Wolfgang
  7. Hi Jörg and Tom, A little bit off topic, but related, so allow me to ask: How is the image quality when using 2x Teleconverter with 8-15mm fisheye? Very soft? I am interested to know since I think about switching to FF sensor, but the options for WA optics for FF are not overwhelming (the new Kenko 2x Pro HD is said to have very good optical quality)... Wolfgang
  8. I had a look at www.Nauticam.com and saw that the housing for EM5III is already available: https://www.nauticam.com/collections/olympus-mirrorless-housings/products/na-em5iii-housing-for-olympus-om-d-e-m5-iii-camera I must, however, say, that I am still not convinced about EM5III over EM1II: the housing comes without the handles and the shutter release lever is inferior and needs an upgrade to become comfortable ("pistol type") - then it costs similar to the NA-EM1II housing that has the handels already built in and also a very fine "shutter-lever"... There is, by the way, aEM1III soon to appear. Presumably it will have the same sensor but better processor (=faster AF) Wolfgang
  9. My 2 cents regarding the initial question of the tread (EM10III). I am not a camera technician, nor a UW camera salesperson, but I believe my view is firm advise: The EM5II (and also the already discontinued EM1I) represent the climax of the Oly cameras with 16 Mpix sensor. As this era is coming now to an end, one can find used camera bodies plus Nauticam housings (EM5II and EM1I) here in the classified section on a regular basis for between 600 - 1200 $ (often including vaccum valve, tray and trigger (tray and pistol type trigger are a versatile, almost mandatory required, addition for the EM5 and EM10 type housings, while the NA-EM1II housing has these features already - this explains the higher price)). This is the way to go. In case there is money itching in the pocket, much more will go away for lenses, ports, extensions etc... (and at a later stage, when the time and the bank balance are ripe, one just upgrades to a new camera body with housing). When you look in treads of general photographers, e.g. DPreview, the EM10III itself is not regarded as a real upgrade to the EM10II by many: it is more a step towards automatic mode "point and shoot" photographers and less customisable as EM10II - many were disappointed by EM10III (they expected a step more towards the EM5II). I would not go for such a camera plus housing both new for approx. 3000 $ (gut feeling calculation, when one adds tray, vacuum and pistol trigger)... Regarding AF performance of the Zuiko 60mm and Pana 45mm macros, I only can confirm what Massimo and Chris are saying: Zuiko 60mm is difficult to use (Pana 45mm works better) with CDAF. Both 60mm and 45mm macros work flawless with PDAF (al least with EM1II). With both 60mm and 45mm macros the manual focus ring is unusuable as too much turning is required for focusing. MF, however, would be very useful for macro but it is practically impossible with both of these lenses. (With the 0.71x and 1x adopted Canon 100mm IS macro, the manual focus ring works very well, as it is expected and from here I know that MF is very useful for macros. AF with this lens is difficult, at most comparable to the 60mm with CDAF (this is the price for using a non-native lens via third party adapter). I personally like this lens as it allows great magnification even without diopter (up to 1:2) at a reasonable working distance, but I would not recommend this lens to a newby (I am probably an eccentric, even most swashbucklers will not like this lens on a MFT camera) - I write this just to add information to the AF/macro part of this tread)... Wolfgang
  10. I designed extension collars for the Nauticam zoomgears for the Tokina 10-17mm and Canon 8-15mm fisheyes with and without the 1.4x Kenko teleconverter using "TinkerCad". This was required since the original zoomgears fit to the lenses adapted with the Metabones 0.71x speedbooster to MFT cameras (EM5II and EM1II in my case), but I use them with the Metabones 1x Smart adapter that is 6.6mm longer compared to the 0.71x booster (the range of angles of view is more useful for MFT sensor with 1x adaptor compared to the 0.71x speedbooster). I printed out with https://i.materialise.com. One zoomgear extension was approx. 15 Euro (with VAT) and delivery was 10 Euro. I think this within range as long as I let not print out hundreds of them... Wolfgang
  11. To my experience, PDAF works better than CDAF for UW use. Before I had PDAF, CDAF was very well sufficient. I became, however, spoiled by PDAF. I would say it is nice to have PDAF, especially when it does not cost a whole fortune in addition... I assume that EM10III has similar AF than EM5II: AF with Zuiko 60mm Macro and Pana 45mm Macro became substantially faster when I switched from CDAF (EM5II) to PDAF (EM1II). I described my experience lately in a post in DPreview generally about PDAF vs. CDAF, have a look in case you are interested. In short: CDAF (EM5II) works fine for S-AF, while PDAF (EM1II) works in addition also with C-AF+tracking: https://www.dpreview.com/forums/thread/4455081?page=6#forum-post-63497234 Note that the example photo was even taken with Canon 100mm IS Macro lens, adapted with 0.71x Metabones adaptor, so focal length was actually 71mm (AF generally works less good when using adapters). Here my post: "I can compare Olys EM5II (CDAF) with EM1II (PDAF) from my own experience: I take photos underwater. Especially for Macro Photography and fish portraits, where AF is difficult but very important, there is a clear difference. With wide angle the difference is not so dramatic, but exists also: I use only the smallest field in the center for focus. With C-AF+tracking, I can first focus on the eye of the fish (that is at this moment in the center of the frame), then I keep the C-AF+tracking active (I have separated this function from the shutter-button half pressed and assigned it to another button, so I can press it with my thumb) and move the frame until I have the frame I want and then release the shutter - the eye of the fish remains in focus all the time. Here an example photo, to demonstrate what I mean: View: original size With EM5II, that also has the same C-AF+tracking function, AF is, in my hands, too unreliable and I would too often loose the focus during framing, so I use just S-AF with EM5II. Also with EM5II I was happily taking fishportraits (I would not say CDAF has let me down), but with PDAF (EM1II) it is clearly easier. Since I am spoiled by it, I would not want to step back... Wolfgang"
  12. PDAF in EM5III and EM1II and the 20 Mpix sensors are clearly an improvement. The EM1III that is coming soon will have probably the same sensor. I do not see an advantage of EM5III over EM1II, to the contrary EM1II is slightly better. In case I would be someone who considers to upgrade from a 16 Mpix MFT sensor, I would pull the trigger now: From time to time used Nauticam EM1II housings are advertised here for approx. half the new price and the EM1II streetprice new is around 1000 Euro. No comparison with any other new MFT camera (with similar performance) and new housing... Wolfgang
  13. Hi, My wife and me have had similar problem: started with three YS-D2 (black) and had several issues (I reported here). Two repairs (one warranty exchange and one costing approx 250 Euro) and one complete loss... I have three Z330 now (no issues so far) and my wife uses the two remaining YS-D2. In case a YS-D2 fails again it will be replaced by Z330... Never again a Sea&Sea strobe! Wolfgang
  14. Hi pmk, I have the Zuiko 8mm fisheye (similar IQ with Zen DP170 or Nauticam 140mm) and the Pana 7-14mm (Zen DP170). Pana 7-14mm IQ is o.k., but 8mm fisheye is superb. Sharpness is generally better, also in the center. Almost no degradation of IQ (sharpness, CA) towards the edges with fisheye - performance of 7-14mm at the edges is poor... I guess the Pana 8mm fisheye gives similar results... Wolfgang
  15. When using two triple clamps (e.g.: https://www.nauticam.com/products/triple-clamp) on both balls of the housing (NA-EM1II in my case), which length and diameter are the optimum for a float buoyoncy arm (e.g.: https://www.nauticam.com/products/o70x200mm-carbon-fibre-aluminium-float-arm-buoyancy-370g-lifetime-warranty) that is attached crosswise to hold a wrist-computer? With such an arrangement, how do you fix a focus light? There is no dealer nearby where I live so I can not test out arrangement by myself, therefore the question... Thanks, Wolfgang
