Lens setup help needed

dirtyleo

I have a 28-135mm with and adaptor and have reversed a 50mm 1.8 on to it,along with a 25mmII tube,,,,,,,,,with these components what is the reccommended setting(starting point) to be used on each lens and what is the magnification with these components used?

This could be mounted either way 50 reversed or the 28-135 reversed would this be any different?

That 72 to 52 adaptor was a bear to find, ended up going via E bay and China,,,,,,,,,cheap enough tho ,shipping included $6.80.

Now lets see if it works taking pic's

Okay here's the deal,I could not achieve focus at all with the tube in place but was able to get clear focus with tube removed (with 50 reversed)from the line up on every possible setting on both lens.The working distance varied from 1 1/2 inch when at 28mm to 3/4 inch when at 135mm,pics tomorrow.

Focus point was at the approx center only of the 28-135 when it was reversed and mag was less.

This setup is looking more and more like a failure.
