  1. I stand corrected I found an updated clarification by IATA that is actually quite surprising https://www.iata.org/whatwedo/cargo/dgr/Documents/passenger-lithium-battery.pdf While it says that you cannot carry spare batteries in checked in luggage under any circumstance but also includes the maximum limit for carry on For batteries in equipment the limit is 15 pieces of equipment (with the battery installed) so say you have a camera, mobile phone, computer, two video lights, and a portable battery pack for your phone: total 6 devices You can then take max 20 spares so in the case above you could take 6 camera batteries and 7 spare batteries per video light each and still be fine. More interestingly you can take your device in checked luggage, now you won't probably want to take a laptop or camera however for what concerns the video lights you could put them in checked luggage. Now the issue that you have is if you have the video lights checked in with no spares and the spares with you how do you demonstrate what are they the spare for? I was recently stopped during a trip and specifically they checked if the spares were matching the batteries So in practical use you need to take both the device and the spare with you and you can take total of 15 devices with battery in place plus 20 spare overall which seems plenty The limit of two spares is for >100 Wh packs
  2. @ChrisRoss is I believe correct in terms of cost weight it will not be light. With regards to the FOV as I wrote that post after realising myself what was going on with the WWL-1 we need to take into account that wet lenses or water contact optics are not directly comparable to a rectilinear lens First and foremost because any water contact optics is NOT rectilinear it will have extensive barrel distortion. So the competitor of such lens is a zoom fisheye however in the full frame camp this options has been missing. You can use a fisheye or a fisheye with a teleconverter no zooming. The reason why those lenses appear sharp in the corners is because the corners are compressed is like looking to a pincushion image and compressing it into the frame. So despite all claims from nauticam you can't really put a resolution chart in the corner and measure resolution because the chart is distorted, this may as well be acceptable depending on personal taste. I want to say though that for those who like genuine rectilinear sea and sea makes lens correctors that seem to work well with 16-35 mm lenses. This is probably the widest you want to go before you incur perspective distortion and make things better around two stops. The WACP fills a gap between your 15 mm fisheye and the 16-35 mm rectilinear working like a 10-25 mm fisheye but is not a replacement for a rectilinear lens. Looking at the WACP 2 on the 16-35mm it shows a fov of 128 degrees compared to the 108 degrees of the lens alone. I would no be suprised that the FOV improvement is almost all on the diagonal and the image does not look rectilinear anymore At the end the FOV on the diagonal matters little because the corners are compressed they look sharp or not there is nothing interesting there the subject is in the centre. Going back to split shots all the shots you see are done with a fisheye. I do not like them, actually the line of the horizon bent by the lens is plain ugly and when i show a split to a normal person they say there is something wrong with it So I started shooting them with a rectilinear lens however this means pretty much f/22 on a full frame unsure if this is practical!
  3. The rules are the same you can’t put stuff in the hold is clearly printed on any passenger aircraft conditions of carriage they will not risk a fire because you are a diver so take them in the cabin is the rule Once you are in the cabin you then follow the limitations of packing specifications Everybody knows it including manufacturers in fact when I did a trip with keldan owned equipment we discussed taking one or two spares that was the maximum and at the end I decided for one set of spares as they would charge quick enough for the next dive Sent from my iPhone using Tapatalk
  4. No you need to read it carefully Page 4 Prohibitions Lithium ion batteries All lithium ion cells and batteries shipped by themselves (UN 3480) are forbidden for transport as cargo on passenger aircraft. All packages prepared in accordance with Packing Instruction 965, Section IA, IB and II, must bear a Cargo Aircraft Only label, in addition to existing marks and/or labels. Packing instructions  M. Under Packing Instructions 966 and 969, it states that “The maximum number of batteries in each package must be the minimum number required to power the equipment, plus two spare sets. A “set” of cells or batteries is the number of individual cells or batteries that are required to power each piece of equipment”. If a package contains 4 power tools (each tool contains 1 lithium ion battery), can 2 extra lithium ion batteries be placed in the package for each piece of equipment for a total of 12 batteries? Yes, providing you do not exceed the maximum net quantity for the relevant section of the packing instruction and the chosen aircraft type. The 12 batteries reflect two spare sets (8) for each of the 4 power tools in the outer package plus one each to power the device (4). So it is pretty clear that 1. You can only have two spare sets including whats in the equipment 2. The weight limit is 5 kg NiMh batteries for strobes can be put in cargo and are not subject to these restrictions In practical terms nobody is going to weight the batteries as in most cases airlines have a weight limit on hand luggage But is very easy to count the batteries I also do not see any reason to carry more than 3 sets for each individual item Sent from my iPhone using Tapatalk
  5. TUI is the first company to resume direct flights from UK to Sharm El Sheikh in 2020 starting from February with a Wednesday and Sunday schedule and adding Thursday from May Easyjet has also secured slots and more will follow I have my boat running from Sharm 1-8 August 2020 so far only open to non UK citizens but now open to UK as well (though I would still recommend flying indirect through instanbul unless you want to be there a few days more...) https://interceptor121.com/2019/07/28/calling-out-to-all-image-makers-1st-interceptor121-liveaboard-red-sea-2020/ I am very excited that Sharm repopens as it is just the best of Red Sea and sailing from Hurghada to go North sucked! For sure in the near future other operator will shift back their boats from Hurghada
  6. I have no upload allowance on this post! Light room looks marginally worse than the corrected DxO has a bit more crop to it and the corners are worse The pull however is not the correction only is also perspective distortion that can’t be avoided and the primary reason why I no longer have a 7-14 mm lens. At 7mm is much worse I found I had it on my blog https://interceptor121.files.wordpress.com/2019/10/perspective409mm-f-8-20191012.jpg?w=1024 Sent from my iPhone using Tapatalk
  7. I posted already somewhere else here https://www.iata.org/whatwedo/cargo/dgr/Documents/lithium-battery-shipping-guidelines.pdf For non cargo you need to follow the rules for batteries packed with or in equipment you can’t carry batteries without equipment that only applies to cargos LiIon is forbidden in any airlines on regular non cargo shipments Sent from my iPhone using Tapatalk
  8. If you dont carry the camera or light technically you cant carry any spares on their own and clearly no packing in checked luggage of any li ion in any way Sent from my iPhone using Tapatalk
  9. The limit for batteries contained in equipment and packed with equipment is 5 kg per passenger with maximum two spares in addition to what is in the equipment So if you have a video light with a battery you can take two spares no more If you have a camera with a battery inside you can also only take two spares The total of your batteries in and out equipment is 5 Kg AA batteries for strobes and NiMh do not count and can go in check in In theory for your gopro you can only take two spares each and two inside so total 2x3=6 and 6 video lights In practical terms I have never seen this stuff put on a scale or a count of batteries but those are the rules
  10. Actually in stills the frame at 7mm is 85 degrees more than the wwl-1 and difficult to cover with strobes 8mm instead is great 95 width and 78 height the strobes cover it perfectly and perspective distortion is limited The wwl-1 narrower than 7mm is easier to cover with lights or strobes Sent from my iPhone using Tapatalk
  11. Example against a rectilinear object 100% correction 0% correction As you can see without correction the barrel distortion is visible
  12. As I wrote on the diagonal is 130 but horizontally has the same fov of the 7-14 All diagonal fisheye are like that so this is normal but majorities of people dont know For me what matters most is the horizontal axis This article I wrote has the table https://interceptor121.com/2019/05/12/nauticam-wwl-1the-best-wide-angle-lens-for-underwater-video-on-the-gh5-and-other-micro-four-thirds/ The 7-14 rectilinear lens has the same horizontal field of view and is actually wider vertically this is because fisheye like lenses compress the frame with barrel distortion. Now 7-14mm is not a useful focal length for me because perspective distortion is so accentuated that the shots look weird also on land more at close range in water Sent from my iPhone using Tapatalk
  13. Blue green whatever basically not good conditions to shoot without strobes and too deep... Which is the reason why haven’t bothered yet Sent from my iPhone using Tapatalk
  14. She is using raw images so this appears a mix of white balance and dehaze I guess the different shots get the appropriate level of correction you need So this could work when you are at depth where colors are still there but not replace flash anyway Blue scatters light and dehaze removes scatter but water also absorbs light both in terms of color and general intensity Looks very promising for ambient light shots at shallow depth for those that are not that good at post processing Still many shallow pictures once gone through current tool look pretty good and not as different as those results Sent from my iPhone using Tapatalk
