  1. I am a diving Medical + critical care Physician and Underwater photographer and would like to chime in on this topic. Firstly, please do not fall into the trap of news or facebook postings that are reflect the author's opinion. Only, peer reviewed Medical Journals should be referenced. In summary, based on multiple medical literature searches, there are multiple vaccines already out and others completing phase 3 trials. All of these trials did not look at asymptomatic (believed to be about 60% of all covid infections) so it is not known if the vaccines will prevent asymptomatic infections or if vaccinated people that are asymptomatic can transfer the disease and infect others. Until detailed studies are completed The ones that are out there are the following: Pfizer 2 injections with about 50% efficacy two weeks after the first injection, 3 weeks between injections and 95% efficacy 2 weeks after the second shot, this efficacy is against the original strain and the initial British strain, It has reduced efficacy against the Newer British, South African and Brazilian variants, efficacy against these strains are believed to be around 60% with the current vaccine.They are tweaking the vaccine in order to provide increased protection against the newer strains, a booster will be made available to those vaccinated with the original vaccine. Moderna 2 injections with about 30-50% efficacy two weeks after the first injection, 4 weeks between injections and 94% efficacy 2 weeks after the second shot, this efficacy is against the original strain and the initial British strain, It has markedly reduced efficacy against the Newer British, South African and Brazilian variants, efficacy against these strains are believed to be around 50% with the current vaccine. They are tweaking the vaccine in order to provide increased protection against the newer strains, a booster will be made available to those vaccinated with the original vaccine. Astra Zenica, 2 injections, better efficacy with longer than 4 weeks between injections with about 50% efficacy two weeks after the first injection, 4 weeks between injections and 95% efficacy 2 weeks after the second shot, this efficacy is against the original strain and the initial British strain, It has reduced efficacy against the Newer British, South African and Brazilian variants, efficacy against these strains are believed to be less than 60% with the current vaccine Johnson and Johnson, single injection, about 70% effective against the original strain, less than 50% effective against the new strains, not as yet approved by the CDC/FDA Novovax about 90% efficacy against all known strains of Covid-19 https://www.novavax.com/sites/default/files/2021-01/UK-SouthAfrica-Trial-Results--FINAL.pdf not as yet approved by CDC/FDA Testing: PCR Covid tests: about 10% false positive and about 10% false negative results depend on adequate sample Rapid testing: about 20% false positive and 20% false negative Hope this helps clear things up
  2. what are you asking for this?
  3. I also had an issue with my nauticam ttl underexposing, it worked perfectly on my d500 but when I switched it to the z7 if failed miserably. always massive underexposure. I contacted nauticam and was told it was an older model ttl converter and only the newer model would work on the z7, Have not tried the newer model as yet. Older model had switches newer one has a dial that is set specific to the strobes.
  4. Housing sold, no longer available
  5. Still available , relisted on ebay due to wrong photo as the main one (old listing showed the Bag not the housing) New listing Link https://www.ebay.com/itm/254110615575
  6. Listed this on Ebay for a 7 day listing, Looking for at least %1500 plus shipping, includes Vacuum valve, pump. soft Nauticam case. Has standard Nauticam fiberoptic strobe setup. https://www.ebay.com/itm/254106699353 Check the listing for photos.
  7. Now available online https://visa2egypt.gov.eg/eVisa/Home;jsessionid=kQwYHWs7qbfw46v-R_9EjOhjqb2Q_74s1dkY3utt.pp-ui-02?VISTK=O87F-CSM7-UL0I-JAIS-O94R-47R0-HA6D-VJTG-K2LG-1YF2-8SVI-HD78-0HEJ-KUQ7-SYOI-JWFA
  8. I have used my F-mount lenses with the ftz adapter on my z7 and have great IQ plus no auto fine tune was needed. Once they issue the new firmware that adds eye tracking, focus tracking should improve overall.
  9. Kenko recently announced a new series of HD teleconverters for both Canon and nikon designed for high resolution digital cameras, They claim they work with Nikon, Canon and Tokina lenses. Not sure about the 8-15 as they don't as yet list it on their site http://www.kenkoglobal.com/photo/lens_accessories/teleplus/kenko_teleplus_hd_pro_14x_dgx.html hope this helps
  10. PM sent, Undercurrent, Amos Nachoum, Aggressor staff 9Wayne, Anne, Andrew), Sri Lankan Government/Embassy, David Home,Annah Evington. Hope this helps clarify
  11. All Whale/Dolphin swimming permits were rescinded by the Government agencies for 2017 pending revision of the "rules". It is unclear if or when new permits for 2017 will be issued. I also had a trip scheduled in March of 2017 that I cancelled for this reason.
