  1. Renting out UW-Photo gear? You are tempting the gods... Maybe you know Bob Halstead? He wrote „NEVER LEND YOUR CAMERA GEAR TO ANYONE IN ANY CIRCUMSTANCES (This is the Gods’ absolute favourite, the gear is certain to stuff up)“ - and I think most forum members will fully agree. Here you can find the full essay: http://www.divebuddy.com/blog/11135/cant-take-joke-dont-take-up-underwater-photography/
  2. It could be helpful if you gave some more infos: Where do you dive most of the time - tropical/clear water or in areas with limited visibility? Only on holiday or every other weekend? (Analogy alert: I need a new car, which one could you recommend?) That said, ask three people and get four opinions... As troporobo said, the 12-50mm is a versatile lens - this is the first lens I would buy, together with the Nauticam port. Good for Macro, good for wide angle, If you are a "macro guy", the second lens would be the 60mm macro from Olympus (or maybe a 45/30mm macro if most of your dives are in murky waters). If you are more into wide angle, the Panasonic 7-14mm is a great lens, even for close-focus WA. And an acrylic port is "good enough" (unless you regularly publish in National Geographic). A fisheye lens is definitively not a good lens to start with - IMHO! Of course you could buy the the Oly "Pro"-line lenses, but do they give you a guarantee for better pics? Nope. A good way to spend the money you save with cheaper lenses is to join an UW-photo workshop. You come from a compact camera, your EM5 will give you much more options for better pics - but also much more options to screw things up... A workshop might be a good investment. The key factor for good pics is behind the camera. Best, Jock p.s.: Here in the forum there is an old thread about UW settings for the E-M5. Or look here: http://www.uwphotographyguide.com/olympus-omd-em5-best-underwater-settings
  3. If the "AmazonBasics Convertible Rolling Camera Backpack" weighs 4.25kg - what do you want to put inside? Camera-Gear? Have fun at the airport... I use an EastPak "Hatchet" which itself is very lightweight (780g). With all the gear that I do not want to check-in it is well above the airlines cabin luggage weight restrictions (economy class) - but it does not look heavy! Absolutely no problems up to now...
  4. Bob, are you still using your Olympus OM-D? I have an E-M5 and used to have exactly the same problems with inconsistent TTL exposure you describe. I was told the fiber optic cables could be the problem - I had cheap ones - and that was it! I bought one Sea&Sea and one Nauticam cable. No more problems since then. But still, as I wrote in an earlier post, IMHO background exposure in Macro with sync speeds of 1/125sec and below and small apertures is NOT dependent on sync speed. So you do not get a darker background (which was the „opener“ in this thread) when using 1/250s instead of 1/125s. The burning time of the strobe is shorter anyhow, so it does not matter what exposure time you set. Pavel probably knows if I am right or wrong. Regards Jock
  5. As I wrote before, a fisheye lens is another option.
  6. If you have a Pana Fisheye and the Nauticam 3.5" dome - take it with you!
  7. Thanks for the photos, Tom For me (without underwater testing, just by comparing the specs) the "want-to have" strobe would be the Seacam: small, beautiful design, 4.400K colour temperature, 130° coverage (GN8 metric / around GN25 imperial), accessories like diffusor, snoot available. When I changed from analog to digital I changed from Ikelite SS200 to Inon Z240. What I really missed was the circular flash tube from the Ikelite. For my personal taste the Ikelite gave a much more "pleasant" lighting; maybe because of the circular tube, maybe because of the colour temperature, or maybe bcause of a combination of both). The Seacam has this circular flash tube, the other two not. BUT: For the price of one 60D you can buy two Inons or Retras....
  8. I am not sure if the 30mm macro lens makes sense underwater. Macro lenses are optimized for - guess what - macro. But with the 30mm lens subject distance definintively will be too close when used in macro mode. As you mentioned, difficult/impossible lighting, and of course only for static subjects. Of course you can use the lens for subjects further away and have less water between the fish or whatever and your lens than with the 60mm lens - but why not use a zoom lens instead? Much more versatile. Jock
  9. Well, maybe because you have to be very brave to be a beta-tester??? If a few pre-production strobes work great on one or two dive trips that does not mean anything. See the problems Sea&Sea has, lots of complaints here in the forum. The Inon strobes are workhorses and over the years have proven to be reliable. Not a bad choice at all!
  10. Hi Marcus, if you have access to a 3D printer (or if such a printing service is available in Brazil) you can find and download a file for printing the Zoom Gear Panasonic 7-14mm on thingiverse.com. Should be cheaper than the Nauticam part. Greetings, Jock
  11. I have the Leak Sentinel (in a Nauticam Housing) and can absolutely recommend it. As Jack mentioned, it constantly monitors the vacuum, even if you switch it off in the evening and back on in the morning!
  12. Ha! Yesterday I disassembled an old non-functional FL2 myself and wanted to post photos and the very same question as well. Funny. Hope someone can help.
  13. The Z240s are workhorses. With a new strobe, be it Inon or Retra, you never know if there will be problems in the first productions. Sea&Sea seems to be infamous for that kind of trouble... Of course you can travel with your gear on Qantas - the question is if they will let you take it into the cabin! From what I have heard (! - never flew with them) they seem to be very strict with the weight of your carry-on bag.
  14. Maybe I need a new pair of glasses, but I cannot find any infos about the new vacuum pump on Miso's website; same for the price. Could someone help, please? Jock
