  1. Sealing looks like a light foam-rubber rather than actual rubber gaskets...

     

    Does not sound half-assed to me. 10mm in 3 minutes is heaver rain than you would get in a hurricane.
    Well that's equal to 200mm per hour... which is less than the 1D series' 254mm per hour resistance. So I apologize for my bad math... it's about 3/4 ass implementation. :uwphotog:

    I don't think you can extrapolate out like that - I think there may be a reason they listed it as a water/3min rating. Seals may saturate to an extent after that point...


  2. Our good friends over at Jim Abernethy’s Scuba Adventures have just had a last-minute cancellation for a shark expedition this coming month. The Bahamas shark trip is well known here at Wetpixel, but has historically been expensive and hard to get on because of limited availability.

     

    There is a significant discount on this trip, and it is rare for a spot to be available at such a good deal. Trip dates are September 19-25, 2008, and price is USD $1989.00.

     

    If you are interested, contact JASA immediately!


  3. Finalists have been announced for the 2009 Raja Ampat Entrance Tag Design Contest, hosted at Wetpixel.com. Vote for your favorite image or design -- the winning image will appear on Raja Ampat's 2009 park tag!

     

    Last year's winning image, a pygmy seahorse with its tail wrapped around a gorgonian branch, was shot by Alex Mustard, who won a week-long dive trip to Raja Ampat in addition to having his image attached to every diver who visited the park in 2008. The winner of the 2009 tag contest will win a week at Raja Ampat's original eco-resort at Kri.

     

    Public voting ends at 11:59 PM, September 25, 2008 (Pacific time). Be sure to log in to Wetpixel before you vote for your favorite image. We'll be awarding a free 1-year subscription of Wetpixel Quarterly to a random voter, but you must be logged in to play!


  4. The commotion created by the divers and sharks did not go unnoticed - dungeness crab, shiner perch, ratfish, dogfish, and various flatfish all wanted a taste (literally!) of the action.

    The crabs seemed greediest, tearing away at the bait to no end. And when not eating, they took the time to attack their reflection in the dome port :bananashark:.

  5. It looks like Wolfgang clarified his remarks:

    The Canon transmitter can not be used in wireless mode.

    Due to the density of water - no matter if it is just two inch deep – wireless transmission quits working. The unit has to be used in wire-mode in order to work from the pool.

    The other big issue to be solved with Canon’s Mark 2 is the firewire signal that comes from the camera. Unfortunately fireware does not travel over more than approx. 1.2m of cable length. Therefore the unit that “translates” firewire into normal “LAN-language” has to stay close to the camera. In my underwater setup a 0.5m long custom-made waterproof firewire cable goes from the camera housing to the second housing that contains Canon’s WFTE-1 transmission unit. The transferred image data is then filed over the second cable - the red one in the picture – to the ftp server. Previously mentioned - it is a specially treated regular CAT-5-LAN cable. Therefore we can view, acquire and edit the images from underwater within seconds after they have been taken.

    I was wrong previously about him actually using the transmitter in wireless mode as intended, but it still seems like an over-complicated setup - I don't see why he can't use a Firewire-CAT5 repeater on each end and set the camera up in tethered mode with either Canon's software or similar (C1, etc). All the instant-view capability, no transmitter required (especially since the wireless nature of the transmitter is not utilized!).
