Good reef macro lens for Rebel EOS cameras?

and then control the aperture to achieve the look i want.

using a speedlight to shoot in water will let you control where you want the light and it'll give you more light so as a result you'll get a sharper image when shooting through the glass.

by controlling the light, you can achieve a completely black background like this

You have high speed sync available though.

My problem with using aperture to control the light is you lose the ability to control the dof.

How did you get the black background though?

Just had a thought, maybe some of you higher end photographers could post some of your shots with descriptions on the settings used, any special techniques, etc, so that others can work towards taking shots almost as great!!

The issue is not so much the settings, but the equipment necessary for such shots. Without off-camera strobes and a dedicated macro lens such shots are next to impossible to achieve. There's no magic setting that allows a little point & shoot or even an entry level SLR with a kit lens to achieve such shots. Add to this the consideration of paying for a full frame SLR body for the best low light performance possible. I'm just a novice photographer but I've learned that photography is a lot like reefing: you can't expect Bubble King results with a Seaclone.

That being said, coral macro shots are easier than fish simply because corals don't move around. Therefore, you can get away with less light, higher apertures and longer exposure times resulting in a greater depth of field. When shooting macro always use a good tripod, turn off all the other lights in the room and shoot directly at your subject perpendicular to the glass. Use shutter delay (or a remote trigger) and lock your mirror to prevent any camera movement whatsoever. Turn off all of your pumps and clean both sides of the glass scrupulously. You'll also need the patience of Job because you'll average in the neighbourhood of one "keeper" for every 50 or so rejects.

Here's some of my macro shots with the Canon 100mm 2.8 and some long exposures under actinics (the lens is also a wonderful portrait lens and not just limited to close up shots):

Thanks Franklin. I think there are still some things that can improve one's abilities with entry level gear, such as tricks over/under exposing, etc. Adam posted some nice pics with just an extension tube, which albeit is still a step or three below a good macro lens, but as with reefing, sometimes we can work around the requirement for high end gear to accomplish the same task. At least I hope so, since after all my reef purchases in the last month, there is no way I can afford a new lens

That would be great. We need help to get these great results

The problem is unless you have my lens and camera you will not be able to get my results with my settings.
The higher end the lens the less light it needs to get good results, same with the camera. So if you use my settings you could be 3-4 stops behind me, giving you dark dull images.

How did you get the black background though?

i use a 580EX ii fully zoomed in and bare blub on 1/64th power triggered wirelessly

i put the glass cover on the tank and put the light on the glass facing straight down (near the front of the tank)


when the fish swims directly under the light, i take the picture. a slight contrast boost in photoshop and the background is perfectly black

this one was taken the same way
