Canon EOS-D30 Review, Phil Askey, October 2000
Review based on a production EOS-D30, Firmware Version 1.00
Long awaited. Canon first revealed the EOS-D30
at PMA this year (with a "tentative launch of Fall 2000"),
they then later made it official
and published full specifications and we got our first hands on with the
D30, though at that stage Canon weren't comfortable enough with the image
quality to allow samples to be published. In August we published an exclusive
preview article with the first large set of samples available on the
web.
So why is the D30 so special? Lots of reasons, it's Canon's
first "home grown" digital SLR, built from the ground up to
be a digital SLR, their previous forays into the digital SLR world, the
EOS-D2000 and EOS-D6000 were joint ventures with Kodak (Canon bodies with
Kodak internals), these cameras are also known as the DCS520 and DCS560.
The D30 comes fully loaded, filled with features and
functionality you'd expect of a camera teetering on the edge of wearing
a "Pro" badge (and probably more deserving than some of those
that do), add to this the fact that Canon threw a curved ball by using
the first ever multi-megapixel CMOS sensor to be seen in a production
camera and you can see why the EOS-D30 is significant.
The other thing that makes the EOS-D30 special is that
it (like the Fujifilm S1 Pro) is helping to open up the "prosumer
digital SLR" market, the retail $3,000 may not be considered cheap,
but there are considerable numbers of non professionals who can afford
(and no doubt will buy) the EOS-D30.
What's the competition? Well, there's Nikon's D1, though
Canon have been careful to distance the D30 from the D1, the D1 was designed
as a professional tool, as such it's faster and better built than the
D30, but with it being "Nikons digital SLR" there are bound
to be comparisons. The other camera in the digital SLR market is Fujifilm's
S1 Pro, based on a Nikon F60 (N60) 35mm body featuring Fujifilm's 3.2
megapixel SuperCCD (generating a 6 megapixel image file) and Fujifilm's
own digital electronics in the "back".
For Canon EOS owners the D30 must surely be a very attractive
way into the digital realm, Canon have been very careful, they know that
many long term customers will buy D30's, and that's why although beta
cameras have been around for a while there's been a long delay for full
production units to appear. It's got to be just right.
CMOS you say?
The EOS-D30 features a 3 megapixel APS sized CMOS sensor
developed by Canon. Interesting? Indeed... When I had that news broken
to me I had to spend a few minutes soaking up just what the implications
are.
CMOS has for a long time been seen as the future of imager
devices, however until now they've been very low resolution, had poor
image quality and have been difficult to manufacture. Somehow Canon have
managed to produce a CMOS sensor which not only has the pixel count but
is big enough (APS sized) to be used practically in an SLR. Below is a
shot of the sensor (taken by setting a long exposure) and a scale diagram
of the effective imager sizes for different formats.

** Effective meaning pixels used to produce final image
As you can see by the data in this table the CMOS sensor
in the EOS-D30 is almost identical in size to the CCD found in the D1
(big by digital camera standards), pixel size is slightly smaller and
thus pixel count is higher.
Lenses
Obviously when you buy a digital SLR you've also got
to consider lenses (unless you already own a small armory of Canon kit
;) Canon are pushing their EF 24 - 85 mm (equiv. 3.8 x zoom) as the ideal
"startup" partner lens for the D30, because of the D30's focal
length multiplier this lens works out at 35 - 136 mm, a useful range of
focal lengths. However quite a few people are also considering the more
expensive "L" lenses. Canon were kind enough to loan me a good
range of lenses, two consumer lenses: 24 - 85 mm and 28 - 135 mm IS as
well as three professional "L" lenses: the 17 - 35 mm L, 28
- 70 mm L and 100 - 400 mm L IS (white!).
*IS lens has optical image stablisation
For the majority of image quality / resolution chart
samples I'll be using the EF 28 - 70 mm L, although there will be a comparison
of the resolution chart using different lenses.

Photographs of the camera
were taken with a Nikon D1, images which can be viewed at a larger
size have a small magnifying glass icon in the bottom right corner
of the image, clicking on the image will display a larger (normally
1024 x 768 or smaller if cropped) image in a new window.
