How does benq's scanwit 2720/2740/2750 compare to epson 4870/4180/canon 9950f?

Hi

My epson 2480 real resolution is clearly under 1200dpi. Scanning at
2400 dpi, downsampling to 1200 and zooming to 200% with acdsee gives
you the very same image, no detail is lost.

As i had in mind before getting the epson, i'll get a dedicated
filmscanner for 35mm. Nikon ls-50 is to expensive for me, regardless
how good it is. Minolta Dual Scan IV would be great, but a great deal
of my negs show damages and scratches drumscanned at only 1300 dpi.

My only feasable choice is BENQ 2750i (2700 dpi, ICE). How does this
somewhat dated model compare to modern, high end flatbeds (dmax, color
reproduction and of course, dpi). Any clues with regard to this
respect?

regards

Since it's a dedicated filmscanner I expect it to be better than either
of these flatbeds. Recently I compared my Canon 9950F with my Minolta
5400, and also with an 'emulated' 2700ppi scanner based on 5400ppi scans:

If you only need to scan 35mm I wouldn't go for one of the flatbeds.

I have experience with the Acer Scanwit 2720, which probably has the
same optics. I find that it is that it is very sharp, and others think
the same. Try searching for reviews of the Acer Scanwit.

Best wishes.

Hi

There's a very interesting and comprehensive review of the 2720 model,
with sample scans included.

However it's quite old, and it lacks any kind of comparison with other
scanners.

regards.
