Summary: Very large and cumbersome scanner but works as advertised. Unlike combination scanners with a fixed light built into the upper lid this scanner has a linear motion upper light that can scan up to an 8 x 10 transparency. The price for this unit is extremely reasonable for all the advertised features. I purchased the unit to scan color transparencies, 4 x 5's mostly, and the results are superb.
Pros: Accurate Color, Good Bit Depth, Good Resolution, Legal size format, Scan large transparencies, Sturdy media holders
Summary: I purchased this Scanmaker i800 to replace or be an adjunct to my old UMAX Astra 2400S SCSI scanner primarily for scanning documents and making PDFs of them. I'm running it as a USB device, not as a firewire device. I may have had some unrealistic hopes about it being a great deal faster than my old scanner, but it's certainly not slow. Initially, I had some problems when using the i800 with Vuescan: I had some bad color registration problems.
Pros: Accurate Color, Easy Setup, Good Bit Depth, Good Resolution, Widely Compatible
Summary: I am a traditional photographer reluctantly going digital. I have 35 years worth of negatives and old photos that I printed early in my career. I had planned to make contact sheets but that was entirely too much trouble so I got a taste of a inexpensive negative scanner and found that I needed more pazazz so I bought the i800 and discovered a whole next generation of negative scanning.
Pros: Accurate Color, Easy Setup, Excellent Software, Good Bit Depth, Good Resolution, Widely Compatible
