Canon Ti1 + extension tube + nifty fifty + canon 77mm close up lens
Yup, I actually spent $3 on an absurd looking 52 to 77mm step-up filter adapter to see if this would work.
Extension tubes are awesome by the way. They are the best $14 you'll ever spend.
The close up lens, not so much. I still don't know if it makes a difference.
Regardless, this is what you can do with it.
It goes without saying you need a ton of light for this to work. I took several photos next to a window in full daylight, and the only one that turned out was this one - shooting directly into the screen no doubt helped that situation. Even at f/11 or so my DoF was about .1 mm, making it extremely difficult to use.
Still, it has potential.
