Not quite. The non-interpolated, optical resolution of the Epson
Perfection 3200 is 3200 x 6400.

"The Epson Perfection 3200 Photo is a good competitor in price and
scanning quality for film solutions. The resolution of 3200 dpi is
excessive until there is glass and focus adjustment is impossible. We
compared it with expensive professional scanner Nikon 8000, and this
single fact shows how high-grade this flastbed model is. Although it
has inferior resolution and no hardware realization of automatic film
defects removment, it is six times cheaper and remains a flatbed
solution. And its real resolution of 1800 - 2000 dpi is enough for
ordinary cameras and films."

Specification:

* Scanner type: Flatbed, color
* Photoelectric Device: Color CCD line sensor, 27200
* Scan area: 216 x 297 mm
* Scan resolution: 3200 dpi (basic mode), 6400 dpi with Micro Step
technology (subscanning)
* Scan speed: 14.3 ms/line at 3200 dpi, 4.6 ms/line at 600 dpi
* Color separation: RGB color filters on CCD converters
* File bit capacity: 8/16 bits

The ability to hand variable negative sizes is important to me, because
I have inherited a wide variety of negatives taken by my family over
the last 50 years. Even so, now that I have the Epson flatbed, maybe I
can focus more on 35mm film? But, wait! I might buy a MF or even a LF
camera, and I just found a place that will let me make my own
ViewMaster disks!
