A few minutes with a lens calculator and the specs for the Sony 18-55 tells me that the max magnification of 0.32x is achieved with the lens set at 55mm and the distance from *image plane* to subject of 300mm. You will need slightly less magnification than that so I think the distance at 55mm will be somewhere between 300-350mm depending on the actual image area of the negative.

You might want to do a quick verification of my calculations before you spend too much time working on mounting both camera and film.

The location of the image plane should be marked on the top of your camera body with this symbol:'Φ' except that the vertical bar here should be parallel with the plane of the sensor. Good luck

I am with Chuck on this one, I dont care if a dedicated scanner could
do better. My only concern is what AG brought up: colors might be off.
I googled the film...:), but I also wanted to pick AG's brain, coz he
can tell me in three sentences more than the whole Net in ten years.
Now I got this idea...what if I used my enlarger? Just prop the camera
underneath with a lens straight up, stick the film holder with the
film in the slot, turn it on, and focus on the film? Then take the
picture.
Is there a reason why this wouldnt work, besides the fact that I have
to figure out the logistics of it as my camera and lens might be too
close, but I am sure I could figure out how to increase the distance
so I can focus on the film from underneath.

Sounds awkward to me, unless you make a mount to hold the camera solidly.

I've made a simple piece of wood that fits on my Meopa enlarger stand
with a 1/4-20 threaded rod sticking out, making a simple, adjustable
copy stand for distances greater than the Oly copy stand can achieve.
That and my cheap little 4x5" light box is what I would use for this
project. If the film holder doesn't lay flat, stick some wooden shims on
it.

I don't know anything about the color head in your enlarger . The little
box I have seems nicely daylight balanced after a couple of minutes warm
up. I used it behind the Oly bellows, slide copier and 80/4 Auto macro
lens for 35 mm film and got good color.
