This is a Canon S3IS with lens adapter,,,,,,,,,,
all images hand held aux ltg plus flash and slave ,still trying to figure that lighting out.The image is a seal from a $1 bill

#1 image is +10 diopter

#2 image is +10 diopter and 10mm of tubes

#3image is +10 diopter and 17mm of tubes

Images are #3,2,1 top to bottom

I made the tubes by breaking the lens out of 3 filters leaving just the 52mm rings that I can stack.

I can't see any difference at all.I was right on top of the subject maybe 2 inches.I did a couple at about an inch but had heavy vignetting lack of light.Put the critical C & C on me.

In doing further reading I am nearly convinced that the use of tubes with a fixed lens and positioned between the camera lens and the object will not do anything for you.

Extension tubes and bellows are used to allow a lens to focus closer than it can do with its own focusing mechanism.

You need to put the tubes between the lens and the camera. Then you can focus closer as Jim said.

Hi Jim and Patti,the camera is a Canon S3is that has a fixed lens(non removable) so I was playing with different things.

BTW I am still dick ,I had to register an account for my wife to get in,something must have happened with my log in capabilities.

Dick, think the last image in the series is the sharpest. FYI, I agree with Patti and Jim but since you're using a fixed lens, you won't be able to do that. The Raynox adapters will work better. I was using a Lumix FZ50 with a Leica fixed lens in a similar fashion.
