I have finally had time to edit and upload my shots from our trip to San Benedicto, Socorro and Roca Partida Islands Mexico. As we headed out into the current at Roca Partida for a safety stop after encounters with 7 species of sharks, a school of yellow fin, being buzzed by Wahoo and Cobia, and three different Mantas, we thought we were finishing one of the best dives of our lives when out of the blue a humpback mum and her two month old calf swam by- then stopped to hang out. Safe to say that was the best dive of my life- what a dive site. Enjoy the shots.
Off to work on my Hawaii blackwater and volcano/lava shots. More to come...
I just bought a scubapro reg bag for $30. It has a shell and padding, plus a nifty sleeve for a roll-on handle. Perfect for packing in the middle of my clothes bag or slipped over the handle of my roller because security always wants to know what it is.
I think it comes down to what you are shooting. If always in open blue water, then the 180 is fine.
If shooting along a reef or macro/muck I find the 45 is the way to go. It lets me control my buoyancy and hover more effectively when close to the bottom (no I don't think it is ok for photographers to lay all over the reef/substrate to steady themselves for a shot!). You don't have to get behind the camera as aggressively to frame the shot.
I think the 45 is the best all around viewfinder. I shoot the D700 on a Hugy housing and the viewfinder does not interfere with the LCD.
