    The first two are at 4:1.

    I tried to clean the dust off better before shooting, but it was almost impossible. The strands of wire you're seeing are only about .001" in diameter.


    The set-up:
    (Just noticed - only one of the lights is on in these.)

    Just noticed that #2 looks like a plank of wood from far away... Kinda cool.

    Thanks guys.

    It's actually a macro coupler, not a reverse mount. It's a 70-200mm f/4L and 50mm f/1.4 mounted face to face.

    I shot these at f/5.6. I should have stopped down more, a lot more. I didn't want them to be soft so I kept it at 5.6.
    I was just looking at some older pictures with the same setup shot a f/32 - they're way sharper than these...
    I'll try again tomorrow. Wasn't expecting the DOF to be so microscopic at f/5.6 (f/32 doesn't buy you much more either, but every little bits helps).

    Used a blank DVD as the background on these.

    (5, 6, & 7 are 4:1)

    (almost the same as 5 - exposed 3 stops longer)

    These three are pretty similar to each other... I just couldn't decide which ones to post, so I'm posting the 3 best.

    This one (even though it is a failure) was pretty cool, I think.
    It's at 16.6:1. I didn't realize that the image would not fill the frame at that magnification...
    Every aspect (even getting it in the frame) of this shot was insanely difficult.
    I had it sitting on a stack of DVDs, adding or removing discs to focus. At this magnification, the thickness of one disc would throw it outside the focusing range - I had to shim the disc with sheets of paper to focus (getting it back in the frame after each sheet...). I do not have a focusing rail, now I understand how they could be a huge benefit.
    Shifting your weight on the floor makes the camera shake...
    Anyway, here it is... I guess I'm just posting it to prove that I tried...

    Just for reference - this thing is about 1mm square, maybe 1.5mm square. You can see how small it is in #3 & 4.



    EDIT
    Just a quick reference shot:

    I might try to combine 5 & 6. The board is exposed better on 6, but the gold parts are blown out.
