I don't have a $5 bill handy. If I give you a $3 and a $2.5, can you
make change?

Using a 105mm f/2.8 VR Nikkor:

Using a 90mm f/2.5 Tokina:

(A bit of an optical illusion on this one).

I'm tempted to take a shot of a $5 bill with a 4x5" camera and a 120mm
f/5.6 AM-Nikkor, but I'm not sure how the lab would react. Besides,
that's a lot of work for a boring subject.

Put an object across the bill first to make it unreproducible and it
shouldn't cause any Secret Service visits... maybe.

I'll say. I haven't shot a roll of 120 in 2009 yet. Here comes the
fall however.

For comparison, best we all use the same target...

Old enlarger lenses can give quite good results. Differences in the
two crops may be a slight difference in focus.
I did not reverse the Componon-S as it has almost a symetrical design.
I also tried with a EL-Nikkor 50/2.8 but got a little better results
with the Componon. This may also be caused by a slight difference in
focus. Results was very good with the EL-Nikkor also. I had a lot of
fun doing this test......

Yes I got great results with an 80mm f/5.6 El-Nikkor. It was not as good
reversed. Details in the recent 'Perfect Macro Technique' thread. I
could only get up to about 1.7:1 magnification without adding more
extension tubes to the bellows. The Spiratone 35mm f/3.5 bellows lens
took me to 5:1 magnification although not pixel-sharp. Supposedly that
is actually an enlarger lens.

Hard to compare

Take a photo of a mm scale/ruler and calculate the magnification against
the sensor size.

The approx. size of my image (the full frame....not the cropped) is about 10
x 15mm and I use a DX sensor (16 x 24mm).
So more than 1:1. For those 5:1, 10:1 etc magnification......it requires a
lot of pre-work....to get a stable setup etc.

I presume that $5 bill is made of paper. Here in New Zealand they are
printed on a plastic film with no texture. Otherwise I could give you
a Nikon 105 shot.

Cotton, actually. Can't find a US 5$ bill?

Not in this part of the world.

This was off of the last roll of 120 I shot. Unfortunately, the film
was apparently a bit old and color shift had set in, but that worked
to my advantage for this:

The Pentax 645n and 120mm f/4 make a fine macro combination _if_ your
support gear is up to the task. My copystand, alas, is not, so I have
to mount it "underneath" my tripod with all clumsiness inherent in
such a setup.

Weird colours indeed. Cool coin, though.

I was afraid you'd feel that way. That's why I didn't get the $3
gold coin out of the vault.

So here's a 100% crop done with a Nikkor 105mm VR, a Nikon 6T close-up
lens, and lit with the R1 Close-up Speedlight system (2 x SB-R200):

This shows more than a trace of CA/fringing, but I'm not about to edit
it out just to make my gear look better.
