Since we tested a Lanovia and have not yet had a Topaz available, we can't say more about the Topaz, but can sure remember the fabulous scans of the Fuji Lanovia. Scanning 40 35mm slides at once . Comparing a 3-D object scanned with a 1200 dpi scanner and the Fuji 5000 dpi scanner. The Fuji is large enough to scan an object up to 45 cm long. Here we show how this scanner handles a large 3-D object, a carved wooden effigy of a jaguar.
Scitex scanner costs less .
