Depends on your budget, but I am very pleased with this combo. I would also recommend buying it locally and not mail ordering it. It's worth having the peace of mind to be able to take it somewhere if there is a problem. Saving on tax really isn't worth it.
Definitely depends on your budget... Unless you have money to burn, the 5DII is a little overkil. Not to say it is not an amazing body, I LOVE mine! But I also love my 7D which can be had for substantially less and does just as good a job. And for most consumers or entry level shooters, the 60D is plenty for less than half the price of the 5dII.
As for buying locally. It is always nice to support your local camera store, BUT tax alone on the 5DII is over $200! How's this for peace of mind, Canon's repair center is in Irvine, CA. And they take care of you, especially if you walk in with a 5DII under warranty.
Anyway, Wayne...
Forget about the top down shots for now. A LOT of your shots are coming out blurry. Some seems to be motion blur but a lot looks like distortion from your photo box. If you insist on shooting from top down, make sure A. You have a quality photo box and you are shooting straight through and not at an angle. Shooting at an angle will distort your image as seen in a majority of your top down shots. B. Make sure your shutter speed is sufficient to stop motion from your hand and if possible the subject. Your 5DII is capable of producing some AMAZING shots at high ISO. Don't be afraid to shoot at 800 or higher and still come away with very useable images. This will allow you to up your shutter speed .
I suggest you concentrate on shooting on a tripod through the glass sides of your tank. Same rules apply, keep the lens perpendicular to the glass and make sure you are shooting STRAIGHT through the glass to avoid any distortion. You also need to turn your flow pumps off to avoid coral movement. This will allow you to shoot lower ISO, higher AV, and longer shutter speeds to increase DOF slightly so not just the tip of the coral is in focus. If you want to produce some amazing pictures, setup a photo tank. A small 5 gal tank with a black back and a nice light will suffice. This will also allow you to position the coral the way you want and even shoot top down with a tripod. The downfall obviously is the fact that you need to be able to take the coral out of the display, but most of the corals you shot look like they are easily transportable.
I hope that helps. Keep posting your progress.
