Don, I have set up and used the ext tubes on the 50mm lens, I used all three to give a good close up. Both photos' were taken at F14, I thought I had set it at f16 but never mind its close.
The first photo the diffuser was set halfway down, Like in the photo with the 300mm lens so the lens was sticking out about 4". You can see how much light has been lost in the bottom half. The 2nd Photo I put it just so as the lens poked out about a 1/4" at the same f stop and it lit up the subject much better, it has still lost a little light underneath but not much.
Both photo are un-retouched, they are straight out of the camera only cropped.
I will carry on playing to see if I can get a more even lighting but I think if it done to much it will lose any modeling effect.
