  1. I will ask panasonic service centre if the hot shoe can be modified but I am not hopeful
  2. My point was that sometimes manufacturer specifications are lacking I am sure that not many people know that the 180mm glass dome and the 8.5" dome have the same curvature radius os 11 cm so although the 180mm is only 7" diameter for a 16-35 lens the sharpness is the same. The 230mm dome is 12 cm radius which is only 1cm wider than the 180mm so if you have a 16mm equivalent lens on cropped sensor the difference is minimal however if you have a wider lens the smaller dome will vignette you will need to push the lens in and this will create more issue than corner sharpness alone I have had long discussions with Nauticam to get the real specs of their domes and I am pretty confident I know exactly what is needed for what and this is not always related to the nominal size of the port
  3. Hi Pavel the 3 pin is implemented on new cameras that do not support a miniflash i.e. Panasonic G9 released after the GH5 Those are supported by Nauticam flash trigger
  4. That is what I thought. As we are at it Pavel can you please clarify the following: 1. Will the GH5 converter also be updated? 2. Is the GH5 converter also compatible with other MFT cameras that have 3 pins and do not supply power to the converter? Thank you
  5. My understanding is that HSS strobe pulses are much faster than shutter speed and it basically keeps going until told to stop so it will need an on and off trigger but could determine intensity on its own. If you have the right firmware you can probably test it. So far I have not found any compelling reason to get those retra this might be one if it works
  6. Unless is very dark at the surface ISO is around 200 400 max with those aperture and speed. Would rack up speed to 1/250
  7. The flash can only start after you release the shutter in terms of intensity my understanding is that the flash emits short bursts at a fixed power until the shutter closes. The intensity is considerably lower than a normal flash. When I shoot with HSS on land although the flash wants to be in TTL I can see that the effect of flash is irrelevant what makes the exposure is the other parameters So the solution from UWT and Retra may work but of course I need to test it as frankly I do not really trust most of what is out there in terms of validation
  8. Thank you Tinman this confirms what I thought. For MFT 2x crop factor a radius of 11 cm is sufficient and this is what the 8" has and I think sufficient for DX too. 5" I would not really go there No comment on full frame as that is not really my cup of tea
  9. I did not have any of the GHx and for video so can't comment. When I was in Tiger Beach I would say the camera would not do one hour continuous recording.
  10. Some settings suck the battery life. Continuous auto focus, Quick AF, and of course LCD brightness and power zoom lenses (I do not use power zoom) are a few culprits
  11. Yes but the land strobe needs to have the 'fire signal' so I guess it is pretty much identical Mine needs to be on TTL mode and this is software and there is no feature to be controlled by the strobe I guess it just fires full stop until it can
  12. I would expect both to be a cut of a 12 cm radius and be made of same thickness glass. either way you are unlikely to see any difference. The 9" white balance port is acrylic for what I recall and that may bother you depending on how the lens is prone to flare
  13. Can't put comments on the video Other than the image being a bit dark looks very sharp. A bit of slow mo here and there but generally all is in focus and sharp as it could be taking into account the suspended particles Close up shots very strong mid shots a bit weaker due to conditions and light/ color but seems a step forward
  14. So the HSS is performed by the strobe not by the converter then?
