Canon 9000F review Introduction

My work with the review proceeds and will be published at about 25th July 2010
For now I have some first scan teasers for you :0)
Enjoy/Stefan

  I will not spend my or your time on tech specs or "what's in the box" related info.
  You can get that from Canon directly [ Here ]
  But in short, Canon 9000F is a flat bed scanner with film scanning facility's.
  And this scanner uses a new LED light source for the film scan facility.

  I will not dig in to reflective (Paper) scanning as any scanner would
  be able to output high quality in this area, so I would once again waist
  your and my time by review reflective scanning quality.

Scanning slide film (what I rely care about)

Focusing on the focus.

Slide mount 1mm above the glass.

Slide mount lifted 2mm from the glass just  to be sure that up is the wrong way to go!

One half of the slide mount removed. This puts the film about 0.3mm closer to the glass. This was a small but noticeable improvement.  

My conclusion of the 4 images above
and the one to the left is that best
focus is found on or at a close
distance above the scanner glass bed.

This indicates a shallow depth of field
and I if you intend to scan mounted slide film I would suggest that you
try to get your slides mounted in thin 1.5mm or less mounts.

The film strip holder supplied with the
Canon 9000F holds the film at a distance of 0.9mm above the glass.
My feeling is that this to distant to
the glass. But this might just apply to
my 9000F unit for others it might be
just perfect. (Manufacturing tolerance!)

Above, Film laid directly on the
glass bed. Now this looks almost
identical to the previous scan*.
(*The one with the half slide mount removed)



Image to the right ->
Slide mounts comes in several
different shapes from 1mm to 3.5mm
in thickness.
From left to right: Kodak 1mm paper frame, Gepe 1.35mm Hinged glassless, Generic 1.5mm glassless,
Old homemade glass mount 2.5mm,
Gepe glassless for diy mounting 3mm,
Old Lifacolor 3mm glassed, Gepe 3mm glassed metal mask mount, and far right a generic glassed 3.2mm frame.

My tests have shown that the
1-1.5mm mounts would be ok while
the thicker ones will degrade the scan sharpness quite a bit.

 

Focus on the focus part 2

Part 2 of this test is the same images as above with the difference that they have
some sharpening applied (Same as for the Canon 8800 review Amount=400 Radius=2,1 And Threshold=0)

Film in normal position.
USM applied.

Slide mount lifted 1mm from the glass. USM now applied.
Now when th images are sharpened you can clearly se that this is worse than the default position. This also means that a thick slide mount wouldn't be the suitable for this scanner.

2mm above the glass, huuuu!

As above. One half of the slide mount removed. This puts the film about 0.3mm closer to the glass compared to the default 1.5mm slide mount. This was a small but noticeable improvement. Even more noticeable now when the USM is applied. 

When sharpening was applied it was even easier to se that the best place
to put the film is directly on or just a few tenth of a millimeter above the scanner glass bed.

Film laid directly on the glass bed as above. Now with USM applied this still looks almost identical to the previous scan*.   (*The one with the half slide mount removed)
