Hello everyone,
"New" to the Wetpixel forums here, but I thought I would share my thoughts on my new Sony XR520V camera and the Light and Motion Bluefin housing.
My reference for comparison is the Sony VX2000/Amphibico setup I have been shooting since 2004. While the Amphibico is certainly the most efficient setup for the "bulky" VX2000 in my opinion, I wanted to move into the hi-def world and improve my "travel friendliness". The Light and Motion housing, LED 1000 lights, XR520 camera and accessories all fit in my roll aboard carry-on with room for my reg, mask, dive log, iPod, and other essential travel accessories with room to spare. And I no longer have to "look like my carry on doesn't weigh a lot" because it really doesn't. The Bluefin is 61/2 lbs. Mission accomplished!
As for the camera, I am very happy so far with its performance. Topside images are excellent; the only complaint I have is the "slow" autofocus. Underwater, the XR520 performs as well as the VX2000 with much less noise. My first dive was snorkeling at Pennekamp State Park at dusk (~6pm on 5/11/09) with two manatees feeding and stirring up the muck to a mere 2-3 foot vis. I then did two days of diving with Pennekamp (molassis reef, statue, etc) on bright sunny days in the afternoon and the color was every bit as good as the VX2000. I also did a lot of "snappers in the shade" testing and I am quite pleased with the results. Then I was off to Boynton Beach for a day of wrecks. On a cloudy morning, 4-5 foot waves, at 95 feet with red filter I was able to manually white balance (even on the "shade" side of the wreck). I was not able to manually white balance at the same location without the filter. The manual white balance on the L&M XR520 is a bit cumbersome (the Amphibico VX2000 is literally one-touch) , but I feel the manual white balance control is essential to producing an acceptable result (even the VX2000 auto white balance underwater was aweful). Two days later I was back in Chicago diving Lake Michigan wrecks, and was able to operate the housing with my DUI Dry Zip gloves without a problem (including white balancing). The LED 1000's are smooth and excellent for macro, but not enough for big wide andle shots.
With AVCHD format I have had to adjust my work flow (and buy more hard drives for storage!). Final Cut Pro 6.0.4 was not able to recognize the camera, so I had to import using iMovie '09 (which was actually very easy, and provided some additional editing ability up front). The Windows-only software provided by Sony is a little cumbersome (there's no "preview" slider as in iMovie) but manageable.
I am very happy with my choice and hope the L&M XR520V provides for years of "Hi-def in a carry on". If this is what you are looking for, I recommend this setup without reservation. I will be editing my Lake Michigan footage professionally to Blue Ray disc in the next month, so will have a chance to compare with published broadcast footage. I will provide feedback on the comparison. I also hope to put some of this initial footage on the web soon..
Hope this helps..
David
