  1. https://interceptor121.com/2020/02/17/focussing-techniques-for-video-part-ii-auto-focus-settings/ Deep dive into settings and methods. Subscribe the blog and donate if this is useful
  2. I have seen the GX9 with WWL-1 CMC-1 and two Inon S2000 extremely compact set up
  3. I have used the 8.5 with tokina on a Nikon D7200 is very big and floaty nice for splits and not much else but it will work
  4. Yes this calculation appears correct however the 10mm extension is semifixed and goes with screws so once fitted you are pretty much done with it and it will be a permanent feature I would not use the 8.5" with the tokina unless you want to do split shots
  5. This thread should not transform itself into a full frame vs cropped discussion however if you are looking at high quality MFT it is pretty much the same as DSLR APSC in terms of bulk Full frame does need small aperture which in turn means more powerful strobes and larger domes. APSC and MFT are 1 1/3 to 2 stops less demanding this means smaller rigs and smaller strobes So can't just consider the housing you need to think about the port system and lighting Cropped sensor and MFT print well up to A3 unless you need more than that or you are after the best low light performance which usually is for top side you will trade the quality for less bulk
  6. Fundamentally you have 4 categories 1. Compact cameras 2. Small format APSC and MFT 3.Large MFT APSC DSLR 4. Full Frame While compact camera are significantly smaller and so are small MFT some large MFT bodies are very similar to APSC or even full frame However the glass weight differs both for the lens and the port If you use dome ports glass weights almost double than acrylic and size grows with sensor size There is a material weight and size difference once you pass step 3 for example a Sony A6xxx or a OMD EM5 are much smaller than a Nikon D500 or a Panasonic GH5 clam style housing. That becomes heavier and more expensive. Once you go in DLSR territory not only the ports get bigger but also the lenses some are in excess of 1 Kg
  7. The 34.7 mm is for the MFT metabones adapter that is smaller than the Sony emount Looking at the port chart the adapter is 50mm you can see it at last page Sent from my iPhone using Tapatalk
  8. If you need to zoom the lens it won't grip. This is the reason to use the adapter as is with the 50mm you can change anything else but that part can't unless you 3D print extensions to the zoom gear
  9. The way it works is that the part of the port system that hosts the metabones is what equalises the mount and then you can use the canon chart. If you don't use that adapter it is not possible to control the zoom on the tokina Adapter is 50mm flange difference is 44-18=26 this is covered by the metabone the other 24 mm is because lenses in DSLR bodies are more recessed than E-mount You must keep the first adapter as is and you can change the rest. in the case of tokina as the dome is one piece there is nothing you can change. if you wanted to use the 4.33 acrylic dome generic you need 20mm extension if I recall correctly And the reason you need the adapter is because the tokina does not fit in the N85
  10. Put the camera in the bathtub and find out yourself is what I do...
  11. The 12-35 is not a useful lens underwater as 35 is too short and f2.8 not needed Also those lenses do not take wet lenses as they extend too much during zoom I have a Panasonic 14-42MkII that I bought on ebay and I only use underwater You can get a more useful 12-60 lens that is more useful for video. For stills i have used it only once as it is too narrow only works for pictures of divers Sent from my iPhone using Tapatalk
  12. The focal range 12-40 is not as versatile. I am very pleased with the 12-60 of the leica and cheaper lumix version is slower but works fine underwater and would be a better buy if you wanted a classic zoom. 60mm means you can still take decent portraits of shy fish and they dont look tiny in the frame Sent from my iPhone using Tapatalk
  13. Avoid the last two options Fisheye will be distorted and you will need to get close but Mustard has shot the whole thistlegorm on a fisheye and nobody had a problem with it WWL-1 is a good option and has a bit less distortion you can zoom it as well if you have zero experience I would start with that IQ is not an issue as it will be much better than the olympus 7-14 that is bulky and will be heavily distorted in the corners
  14. The RX100 working distance increase as you zoom approaching one foot on land that becomes 40 cm in water so it will go back an forth the focus point and generally fail until you zoom out
