So far I'm not too concerned about DOF, maybe I'm missing something? I've been shooting macro on my camera almost exclusively, and want a short DOF, am thinking the diopter should not be an issue.. Bigger issue is getting natural light through the lens.. my slave strobe is so strong it whiteouts a photo, and the in-camera flash does not work on the super macro setting.. Well, it does (somehow finally figured it out) but does not illuminate the subject. You can see it on this octopus photo, I didn't use the diopter. The far eyeball got the flash, not the near one.

Jenny, you are getting some really nice creature shots...and with super macro, there are a few new issues.....Sandra has been doing a lot of super macro with a 100 mm lens and a 7x diopter....and also with a 10 x diopter....She actually prefers the 7x because you lose so much depth of field with the 10x, than a Nudibranch can be sharp for it's whole body unless it is almost exactly perpendicular to you with the 10 x...where as with the 7 x, she can have the eyes sharply in focus, all the way to the rear end, even if it is facing her.....To do this, it takes a really powerful diffused light, and a tiny little aperture to shoot through--like F32.
There are many ways to add light to your images....and if there is a nasty hot spot from a powerful light source, you can use some do it yourself diffusing--even wax paper taped over the light can help alot. In other words, you "could" PUT DOWN several flashlights each with a few layers of wax paper on them...and this should allow you to get to a lower f stop...and then get the entire creature entirely in focus.
On a related note, when Sandra is shooting a nudibranch at night....if I come along with my huge dual video lights and look at what she is shooting with my lights--she ends up pissed at me later, because the ambient light is increased so much by my lights, that it seriously alters the settings she would need to use ( she shoots manual, so for her to "use" my lights, she would have to adjust specifically for them).
I know some times a photographer wants a fish face in focus, and everything else soft....but I don't like this for all shots...I lean towards the whole animal in sharp focus, and the background as getting soft.....
