  1. I wanted to give an update to my boat scheduled for July 31st 2021 First of all there are procedures on my boat: · Guest agree to the use of disinfection (chlorine), this is needed as we must disinfect with bleach (e.g. on bags). · Guest present a printed PCR Test (same one used to enter Egypt) prior to boarding the liveaboard. · Temperature will be measured directly before guest are allowed on board and will continue on daily base. · Wearing a mask on board is requested, in closed areas of the salon it is mandatory except during meal time. · Air conditioning in public closed areas can increase the spread of the virus. We will not run the AC in salon if guest do not follow mandatory mask wearing. Instead doors and windows will be open all time to allow air circulation. · Air conditioning in cabin will be operated as usual, each cabin has an independent system. · Guest are recommended to bring their own deck towels; cabin towels are provided but must stay in cabin. · We have successfully implemented served buffet style on board; guest do not have to bring their own plates etc. · Water dispensers are cancelled as we consider them super spreaders, water will be served in bottles. · Guest have to bring sufficient amount of single use mask for their period of stay on board. · Gloves are not required for guests, we prefer regular hand washing. Hand sanitizer are provided in all public and private areas. · Briefings will be held outside whenever possible; we move as many of the activities to be outside. · Additional liabilities are required to be signed as request by Egyptian authorities: e.g. Declaration before/on flight PCR Testing prior to departure from Sharm El Sheikh (as of 14.02.2021) There is an official testing facility that issues a PCR Travel certificate in Sharm El Sheikh. The Pyramid Hospital (Governmental Hospital) offers the PCR test daily between 09:00 H (9 AM) and 17:00 H (5 PM). No appointment is needed. You need to bring original passport and flight ticket. Please take copy of all passport pages and entry stamp as well as flight ticket with you. PCR Test price is supported by Egyptian Authorities and is about 30 USD. The PCR Test result will be available within 24 hours, you have to bring your original passport and receive it in person, no email service is available. If the airline you are booked with or the country you depart to requires a negative PCR test, plan enough time to receive the PCR Test certificate. The second part is that currently boats run at 50% occupation. I originally booked a boat for 12 people but the agreement I have is that I will get a boat for 20 in case the limitation is in place I also had several cancellation last year. As the boat was already paid for and it is still running those ended up as write off of deposit and as such I still have 5 spaces price is unchanged at €1250 I also want to stress that being vaccinated does not matter to Egyptian authorities and even if it makes you safe there is still a risk one of the crew gets sick and the whole trip has issues so each guest has to check their own travel insurance arrangements finally right now you cannot travel to Egypt and any insurance is void from UK and each market has different view of what essential travel is
  2. Good article I do not fully agree on the size penalty of Olympus Pro model the EM1 housings are not very large at all Nauticam makes them bigger putting handles around them. Panasonic GH5 is big because the camera has a massive heat sink and is a video beast If photos are your only objective a Panasonic GX9 or olympus that is not EM1X is totally adequate as @Alex_Mustard said as long as 20 megapixels is enough. I also want to say that the average MFT user (without offending the category as I am one) is less capable underwater as usually is a guy that came from bottom not downgrading So for DSLR you can go down to APSC DLSR if you want to go mirrorless is MFT and there are smaller bodies
  3. Ah ok so it is the sigma 15mm fisheye which I do not consider as I have a canon 8-15mm
  4. Is this the 105mm the 60mm or both? I have a L mount full frame with Sigma MC21 and so far worked with all canon EF but there is an l-mount native 105mm so am suprised about focus motor is this an old lens?
  5. No he has a Z mirroless and the adapter does not support autofocus It is an issue of all mirrorless full frames and the reason not to buy one lol
  6. I guess he meant to use the nauticam viewfinder on the housing as a tool. Obviously there is no OVF and for macro is not such a good idea either as it would be pitch black most people switch to live view on dslr so they can see something
  7. As the port for your wide angle lens is the same take them all There is not a lot of macro in the red sea but 105mm will work fine for portraits as the water is clear. You don't need the 60mm Sharks would benefit from a wet lens if you cannot afford a WACP is there a fixed 28mm prime you can use with the WWL-1? Results are good You can use your 14-30mm at 18-20mm in shot in clear water with sharks as blurred edges will not be a major concern. This lens however will most likely be bad for reef shots where you will use your fisheye
  8. The nauticam MILC housing have their own viewfinder. In order to benefit from a good view is recommended to go for a camera that has an EVF with high resolution. This pretty much limits you to two models at present from Panasonic as Olympus only makes 2K viewfinder cameras. Panasonic G9 would probably be your best option for photos however it is relatively rare to find second hand housing but there are some great offers on the camera itself. The GH5 also has a high resolution viewfinder. Olympus cameras can be found cheap and the housing costs less and is smaller. EM1MKII is discounted heavily and will work fine however the EVF is average at 2160 dots vs 3680 of Panasonic Lens wise you have a choice of 30,45,60 mm depending on what you shoot plus additional wet lenses to get you closer I have written a lot about many thing for MFT on my blog http://interceptor121.com
  9. Just finished a short write up to cover and compare video, cine and log gamma https://interceptor121.com/2021/02/16/choosing-the-appropriate-gamma-for-your-video-project/ If your camera has all those options and you are confused this may be useful
  10. The fact that Sony performs noise reduction that generates problem is a fact I also said the average user may like that but I do not I am offering my opinion and as such you can disagree with it but you need to accept it I am afraid
  11. I do not own this camera so I do not have direct experience with it but you do not need that you can see some design choices and how they pan out when you understand how a camera functions. Sony applies super strong noise reduction which tends to crush shadows and blacks in log mode. This comes from the fact gain is -10 dB under. It happens in all other modes but with less consequences. This also generates strong chroma noise in shadows so you need to make sure you exposure bright (which as side effect means destroying color accuracy) Probably their approach is to bake in a lot of processing to that the average user gets great results straight out of camera or something that looks like great results. I do not like this approach so I don't buy Sony lots of people are happy though with this I am not as it can't be disabled so I don't buy into Sony in general
  12. I did not say not to use V-LOG. What the article says is that the implementation is camera specific and in some cases does not present benefits especially for smaller sensors. Right now I have a GH5 and S5 from Panasonic and I am in discussion with Nauticam to see if they will make a housing for the S5 that I can use for ProRes RAW. Other than this specific constellation I am not planning any upgrade from the GH5 that meets all my current needs. There is nothing better on the market at that price point and with all the lenses I have
  13. The Nikon cameras have some issues in video and lack most of the exposure tools you will need. I recommend you consider something different unless you have already planned for an external monitor The Sola are daylight temperature around 5.5K typically as this is in the range of the camera auto white balance it is not essential to set it
  14. Some people do dynamic range tests on video there are some issues with the process but results are comparable The canon r5 has the same DR of the GH5 and likewise the R6 In essence the Panasonic Lumix S are the best cameras right now for video followed by Sony A7S3 that has some really bad quirks The rest of new digital consumer cameras are not better than the GH5 BMPCC ZCAM even better but worse ergonomics and no IBIS This is where we are right now if you want the best video orientated digital camera get Panasonic S1H the rest are far far away Sent from my iPhone using Tapatalk
  15. Water reduces sharpness and contrast So there is not much point optimising those factors in the camera The average underwater scene has less dynamic range than what a camera can capture today using a standard mode More important is to have codecs with a lot of bit depth 10 even 12 bits and as ‘RAW’ as possible as many tones are squashed in a very flat image This is why sony or canon cameras without 10 bit 422 video will always be crap compared to the GH5 Now finally there are some 10 bits implementations and also prores raw and blackmagic has 12 bits so there is much more choice Sent from my iPhone using Tapatalk
  16. Sharper on land doesn’t correspond to underwater Operating at constrained depth of field removes advantage of large formats. This is true on land and underwater. With regards to actual sharpness achievable in water there are no studies that I am aware but if people get great result with lenses like tokina which is absolutely horrid and soft it means sharpness drops considerably Wet lenses preserve sharpness so a wet lens and average zoom may be better than a great lens behind a dome Underwater photographers are not usually skilled on physics nor optics so they just look how a picture comes out there is very limited data available Sent from my iPhone using Tapatalk
  17. Allowing more light in always result in higher dynamic range and better performance. You gain at least 2 stops so you have equalised the land benefit of full frame When you operate traditional optics the full frame benefit is essentially zeroed Sent from my iPhone using Tapatalk
  18. The WACP allows you to shoot at wider aperture The cost is very high and the bulk even more so you need to consider that I see it an option for a resident professional guy but not for a hobbyist or someone travelling a lot Sent from my iPhone using Tapatalk
  19. The sigma 17-70 is on the port chart with the 8.5 acrylic port not sure why it would need checking for the extensions. The 180mm dome will work fine as the lens is narrow and is the same radius of others Canon 8-15mm works fine with the 140mm no need for bigger. 180 does not work. 230 is huge try all you can to avoid it
  20. If you use the lens as is 16-35is equivalent to 24-50. This is inadequate for underwater use. I would consider a Sigma 17-70mm it covers most reef shots and a Tokina 10-17mm fisheye zoom for wide work You need a minidome for the Tokina but the Sigma 17-70mm will require a large acrylic dome For macro canon 60mm or sigma 70mm As the camera is super35 you need to look for APSC crop lenses they are more suited to wide angle work and lighter
  21. If you can only record to card GH5 or s have a 400 mbps codec that is excellent Sent from my iPhone using Tapatalk
  22. Yes Alex Ribeiro I remember now I have the canon 8-15 myself is a great lens and its fisheye There are adapters for any of the cameras you mentioned As focal for macro on crop 60mm is enough you will need some form of stabiliser In terms of ergonomics the zcam needs a monitor but records ProRes raw I think also the new sony but I hate Sony ergonomics and would not recommend it Perhaps check what you prefer as output if you use resolve the bmpcc has a 12 bits codec too which is plentiful I would not discount the Panasonic GH5s the 8-15 works very well as fisheye zoom and is cost effective and portable as you can record on card while the other options require power and ssd drives In my experience underwater cropped format do better and those are all crop so it boils down to personal preference. I am surprised about issues with nauticam so perhaps look at the other two options and good luck! Sent from my iPhone using Tapatalk
  23. Most likely countries that are desperate to get tourists will be happy to get you in, there you will find none of your boat crew or resort to be vaccinated. On your return you may be forced to quarantine. It is a bit more complex than just thinking about you
  24. I have finally completed my dissection of Panasonic V-LOG. I have not analysed other formats but I suspect there are similar methods at play https://interceptor121.com/2021/02/07/the-truth-about-v-log/
  25. There is a guy in Indonesia that shoots the BMPCC6K and he is not overly impressed by the ergonomics. 16 for APSC is not that wide and will require a dome I can't recall his name right now when it comes back to me I will repost
