[Editor's note: The Canon Digital Rebel has been discontinued. There is
a review of the replacement, the
Canon Digital Rebel XT]
The Canon Digital Rebel, also known as the Canon EOS 300D, was introduced in
October 2003 and was the first digital SLR (DSLR) to break the $1000 barrier at
its introduction price of $899. In fact it's still the lowest price DSLR on the
market. It is also available as a kit with the EF-S 18-55/3.5-5.6 lens (more on
that later), and is still priced below $1000 ($999).
Though it's a Rebel, which is the designation for Canon's most basic, entry
level, cameras, it has many features you might only expect to find on more
advanced models, such as depth-of-field preview, white balance bracketing and
flash sync at 1/200.
The CMOS sensor is 22.7 x 15.1mm and can generate a 3072 x 2048 pixel image.
Since the sensor is smaller than a standard 35mm frame (36mm x 24mm), lenses will
have a narrower field of view when mounted on a Digital Rebel than when mounted
on a full frame 35mm camera. This gives rise the the 1.6x "cropping" or
"multiplying" factor, so a standard Canon 50mm lens when mounted on a Digital
rebel will give the same field of view as an 80mm lens (50 x 1.6 = 80) would on a
normal full frame film body.
There are 3 image sizes and a total of 7 image capture modes:
Large/Fine: Approx. 3.1MB (3072 x 2048)
Large/ Normal: Approx. 1.8MB (3072 x 2048)
Middle/Fine: Approx. 1.8MB (2048 x 1360)
Middle/Normal: Approx. 1.2MB (2048 x1360)
Small/Fine: Approx. 1.4MB (1536 x 1024)
Small/Normal: Approx. 0.9MB (1536 x 1024).
RAW: Approx. 7MB (3072 x 2048)
The Canon Digital Rebel is an SLR body, so there's no lens if that's what you
buy. However there is a kit which includes the EF-S 18-55/3.5-5.6 lens -
which is reviewed here in a separate
article. Basically this lens gives you similar coverage as a 28-90 lens on a
film SLR in terms of angle of view. It's a decent lens, better when not used wide
open, and is certainly very good value for only $100 when purchased with the
Digital Rebel body. Note that it is ONLY available as part of the kit, so if you
want one, buy the kit. If you buy the body, then decide you wish you had bought
the lens, you're out of luck if you want a new one. You'll have to search around
for someone selling a used one.
There are the usual Canon EOS exposure modes found on all film based consumer
EOS cameras, so if you've ever used a Rebel or Elan, these will be very familiar.
The "Creative Zone" modes allow more user control (for example you can select ISO
and one shot or continuous shooting). The "PIC" modes are designed to
automatically give the best choice of settings (metering mode, AF mode, shooting
mode, flash mode, ISO setting) without the user having to think much.
Creative zone modes:
Program AE (shiftable)
auto depth-of-field AE
Programmed image control modes ("PIC" modes)
E-TTL autoflash program AE
ISO settings and noise
The camera can be set from ISO 100 to 1600 in full stop steps (100, 200, 400,
800, 1600) in the "creative" modes. In the "PIC" modes ISO is set automatically
to ISO 100, 200 or 400, depending on the mode. For example in portrait mode, ISO
is always set to 100. In sports mode, ISO is always set to 400. In the other PIC
modes, the ISO setting depends on shooting conditions.
Because of the large sensor, and hence large pixel size, noise levels are much
lower than normally found on digicams with physically smaller sensors. Below are
100% crops from test images shot at each ISO setting. At ISO 100 and 200 noise is
pretty much invisible. At ISO 400 there is just a hint of noise. At ISO 800 noise
is visible and at ISO 1600 it's quite evident. However remember these are 100%
crops. The samples are 107 pixels square, so the full image would be 28x wider
and 19x taller. On my monitor (17", 1280x1024) they would represent sections from
something like a 20x30 print.
There are the usual preset modes, which are auto, daylight,
shade, overcast, tungsten bulb, fluorescent light, flash. There is also a custom
mode, where you take an image of a neutral tone card (white or gray) and then use
that as the color reference. In addition there is the ability to bracket WB in
steps of +/- 5, +/- 10 or +/- 15 Mireds over a sequence of 3 frames. A
Mired is a unit of color correction (it stands for
REciprocal Degree), but it's a pretty small
unit as you can see from the image sequence below.
Under normal outdoor conditions, the auto WB setting does a good
job, but indoors under difficult lighting (e.g. tungsten) it's not so good. The
custom mode always does the best job, but takes a little time to setup since you
first have to shoot an image of a neutral card, then use the menu system to
select that image for the custom WB reference.
Note though that you might not always want an image fully
corrected to standard "daylight" color balance. Here's an example of Auto and
Cloudy WB taken on a fully overcast day. The shot on the top left was taken using
Auto WB, the shot on the top right using the Cloudy WB setting, the shot on the
bottom left was taken using custom WB based on a shot of a sheet of white paper
as the reference and the shot on the bottom right was taken using Auto WB, but
later color corrected in PhotoShop.
I think the Auto WB shots gives a better impression of what the
scene looked like from a subjective viewpoint, though the Cloudy WB shot maybe
has more "accurate" colors based on what it would look like under
"standard" illumination conditions (i.e. sunny daylight). The custom WB probably
does even better at producing "standard" colors, but it's pretty close to the
Cloudy shot (with a touch less magenta). Just to show that all this isn't really
that important, the bottom right shot is the top left shot after a slight color
tweak in PhotoShop and is, I think, the best of the four! Personally I don't
expect the camera to fully optimize colors to what *I* will like best. I expect
to work on all my images. Some newcomers to digital though expect 100% perfect
shots right out of the camera every time. Realistically, they will be
disappointed quite often.
Here is a neutral (gray) target shot under illumination from a
100W tungsten bulb. You can clearly see that neither auto WB nor Tungsten WB do a
particularly great job, but the custom setting is very good. In passing I'll note
that the 10D shows similar performance, so this isn't just a Digital Rebel
In general if you want "standard illumination" colors rather than
effects, it's probably better to use the preset modes rather than leaving the
camera in auto WB all the time, especially when shooting indoors, but if you want
precise color, use the custom WB mode. Note that if you shoot in the RAW mode
rather than JPEG, you can adjust the white balance after you have taken the shot
when you convert the RAW file to a TIFF or JPEG. This gives you the most
There are 4 focus modes, One-Shot AF, Predictive AI Servo AF, AI Focus AF
(automatically selects One-Shot AF or AI Servo AF selected according to shooting
mode), Manual Focusing (MF). However these modes are not user selectable. The
camera chooses the AF mode depending on the shooting mode. For example in the
creative modes, AI Focus is used. This means that if the subject is static, One
Shot AF is chosen, but if the subject under the active AF zone(s) starts to move
towards or away from the camera, the focus mode will switch to AI Servo AF and
focus will attempt to track the subject as it moves. One shot AF is used in most
of the PIC modes, but in the Sports mode AI Servo is used.
The camera normally operates in a 35 zone evaluative metering mode in all
modes except for manual.. Partial metering is available only in conjunction with
the exposure lock button and when in M, Av, Tv or P creative modes. There is no
indication of the partial metering area (9% of full screen) on the viewfinder
screen. In the manual mode, default metering is centerweighted, but exposure lock
activates partial metering. There does not appear to be any way to decouple
exposure lock and partial metering. If you want partial metering you have to have
exposure lock. If you want exposure lock, you have to have partial metering. In
the PIC modes, metering is always 35 zone evaluative.
The viewfinder image is rather small (0.8x) and has 95% coverage. The relative
small image size is probably a consequence of using a pentamirror system rather
than a pentaprism. Though a pentamirror is lighter and cheaper than a pentaprism,
it also loses more light and so to compensate for this and to brighten the image,
the image has to be made smaller. There is a built in adjustable (-3 to +1
diopter) dioptric correction. The eyepoint is 21mm. Coupled with the smaller
screen size this means you can see the whole screen of you wear glasses, but you
do have to have your glasses pressed against the rubber eyepiece cup to do
There is a rear mounted 1.8" LCD screen for image display, with 118,00
displayed pixels. It gives 100% coverage of the image and there are 5 levels of
brightness. Like all DSLRs, the LCD screen can only be use to view images after
they have been taken. Unlike digicams, there is no "live" display of images. This
is impossible in DSLRs since there is a mirror between the lens and sensor and a
mechanical shutter, so no light reaches the sensor until an exposure is made.
The Canon Digital Rebel displays a comprehensive set of data, including an
optional histogram in both shooting and playback modes. Displayable data includes
date, time, shutter speed, exposure compenstaion, ISO, metering mode, shooting
mode, image size and quality, number of frames shot and image # being displayed.
An example is shown below
The quality of the LCD image is excellent - much better than it appears in the
image above. For some reason it's camera shy and doesn't reproduce well!
On replay images can be displayed one at a time of in groups of 9. It takes
about 5 seconds to display the 9 frame index page (1.6MB files). The image can be
magnifed up to 10x to check focus.
Many of the standard Canon EOS SLR accessories fit the Digital
Rebel, from remote releases, through extension tubes to external Speedlites.
Examples of typical accessories purchased for the Digital Rebel are:
Battery grip BG-E1 (holds two batteries, doubles shooting time)
Semi-hard case EH-16L (holds camera plus 18-55 lens)
AC Adapter CA-PS400
Remote Controller RC-1
Remote Switch RS-60E3
The Canon Digital Rebel has a built in flash with a guide number of 13 (ISO
100, meters) and an angle of coverage the same as an 18mm lens mounted on the
Digital Rebel. The approximate maxium range of the flash is given in the
There is a red eye reduction light (white) which can be user selected. The
Digital Rebel takes any of the Current Canon Speedlites which attach via the
hotshoe. The Digital Rebel supports E-TTL flash capability and the built in flash
is E-TTL (this means there is a preflash used for metering before the main flash
fires). There is no PC socket for external flash connection.
There is no flash exposure compensation available on the Digital Rebel body.
To get flash exposure compensation you have to use an external Speedlite with
that function built in (e.g. 550EX).
In the indoor flash tests I tried, exposure and color balance were pretty
good. I'm not a big flash shooter myself, but I was happy with the results I
Timing measurements were performed by imaging the sweep second hand of a
running analog stopwatch. Measurements were repeated several times in order to
average out errors. Errors are estimated to be smaller than +/- 0.1 seconds.
From the camera in the "Off" condition to the first exposure takes a minimum
of 3.5s. This is with the lens in manual focus mode. The time will be longer if
the lens has to first achieve focus, so a realistic estimate of camera-on to
first-expose time would be 4 seconds.
In continuous shooting mode the frame rate was measured at 2.5 frames per
second for a maximum of 4 shots, consistent with Canon's specification for the
Digital Rebel. Using several "normal" speed CF cards (Viking 512MB, Simple
Technology 64MB) the Digital Rebel took 14 seconds to fully write 4
Large-fine JPEG frames shot at ISO 100 (average file size 1650 Kbytes). However
you don't need to wait for all 4 files to finish writing before you can shoot
For example, in continuous mode, if the shutter is held down, the first 4
frames shot at a frame rate of about 2.5 fps, the next 8 frames shot at 1 fps and
from there on the frame rate dropped to 1 frame every 4.5 seconds. This latter
rate is consistent with the write time for a file (measured at 4.5 seconds in the
paragraph above). Clearly the Rebel has various shooting and writing buffers.
When they are all filled, the frame rate depends on the time to fully write a
file. These rates will certainly be somewhat influenced by the speed of the CF
card used. A faster CF card won't change the maximum shooting rate of 2.5 fps,
but it will probably speed up the reduced shooting rates which are ultimately
limited by the rate at which files can be written to the CF card.
If you want fire off 4 shot bursts at 2.5 fps, you can fire the first burst
starting at 0 seconds, the second burst starting at 5 seconds, the 3rd burst
starting at 10 seconds, the 4th burst starting at at 24 seconds and the 5th burst
starting at 42 seconds . Again you see the effect of the buffers filling up.
The Canon Digital Rebel uses the Canon BP-511 battery which is common to a
number of Canon DSLRs and Powershot series digicams. They are easy to find both
as Canon OEM products or generic copies. A line voltage powered charger for one
battery is supplied with the camera.
Canon claim around 600 shots per charge if the flash isn't used, or about 400
shots with the flash used 50% of the time for normal temperatures
(68°F/20°C). At low temperatures (32°F/0°C), this drops to 450
frames without flash, 350 frames with 50% flash usage.
The Digital Rebel comes with software support for both the Mac and PC. Adobe
PhotoShop Elements II is provided, and it's a decent basic image editor.
Certainly enough to get the average user up and running. Canon also provide their
own software suite (Zoombrowser) for downloading images, browsing and cataloging
them and converting RAW files to TIFF (8 or 16bit) or JPEG files.
The Canon Digital Rebel is compatible with CP direct, Bubble Jet direct and
Pictbridge enabled printers, so you can print directly from the camera without
the need for a computer.
Unlike many "do it all" digicams, this is a Digital SLR and has the features
you'd expect to find on a film SLR. There's no movie mode, no voice recording or
sound mode, there's no "B&W", "Sepia tint" or other odd color modes. It
doesn't give a real time display of the image. It doesn't play MP3 files.
Basically it's a film SLR with a digital sensor replacing the film and this is
pretty much the case for all DSLRs from all manufacturers. It's serious equipment
for serious digital still photography.
Image quality is high. Better than anything you'll get from an "all in one"
digicam, mainly because of the larger sensor and, of course, the ability to pick
and chose lenses. In particular the low light/high ISO performance of the Digital
Rebel is much better than that of digicams using smaller pixles. In s few side by
side tests with an EOS 10D I could see no difference in image quality (though
note that the default settings for contrast, saturation and sharpness
are higher on the Digital Rebel then the 10D, so default JPEGs from the two
cameras may look different). Since the two cameras share the same sensor (and
presumably very similar electronics and software), this would be expected.
If you have the bandwidth, Canon have some
Digital Rebel images for download, and these are available as both JPEG or
TIFF files. Note that the TIFF files are 18MB each (there are 6 available), so if
you don't have a broadband connection go for the JPEGs ("only" 4.5MB each!).
You'll still have a long slow download of course, but it will give you a good
idea of the image quality that the Rebel is capable of.
What's good, what's not so good?
It's ahrd to find too many faults with the camera. If I had to find faults,
I'd say the viewfinder display is a bit small, but you quickly get used to that.
The auto white balance could also be better in some situations (e.g. indoor
shooting under tungsten light), but that's not a big deal for me or anyone who
expects to do some image optimization prior to printing. The lack of user control
over metering and AF modes can also be somewhat frustrating for more experienced
photographers who like total control, but it's something the novice DSLR user
might not really notice.The lack of flash expsoure compensation could be a
problem for heavy flash users who don't like the auto settings. These and other
differences from the EOS 10D are disccussed in more deatil in a seperate article
comparing the EOS 10D to the Digital
Rebel (EOS 300D)
What's not so good are really the things I'd like to see but which the Canon
Digital Rebel doesn't offer - but then if it did it would be $1500, not $900 and
it would be an EOS 10D not an EOS Digital Rebel! I don't much like the silver
body and under some lighting conditions it can be a bit hard to read the labels
on the controls (light blue text on a silver background isn't as clear as white
on black), but that's a pretty minor complaint.
The Canon Digital Rebel is an excellent camera at a remarkably low price given
the cost of other Digital SLRs. No doubt prices will drop further and cameras
will improve over the next few years, but right now the Digital Rebel sets a
price/performance standard that's hard to beat. It's clearly better and more
versatile than similarly priced non SLR digicams in the same price range, though
it may be slightly larger and you do have to buy lenses for it. However the
18-55mm kit lens is a very good performer, especially when stopped down a stop
from full aperture (
see separate lens
test on the EF-S 18-55/3.5-5.6) and if you're buying the Digital Rebel and
you don't have a wide-angle lens already (remember, 18mm on a Digital Rebel is
equivalent to 29mm on a full frame camera), I'd recommend getting the kit with
this lens included for only $100 more than the body itself.
Photographers with no investment in Canon lenses or who already have an
investment in Nikon lenses will probably look at the new Nikon D70 DSLR ($999 or
$1299 with an 18-70 "kit" lens). It's certainly looks like a nice camera, but
this isn't the time or place to address the "Canon vs. Nikon" issue! There's a
full review of the D70 here on photo.net. In
the rapidly evolving world of digital cameras it's probably true that whatever
you buy will be replaced by a better and/or cheaper model in about 12-18months.
Of course if you wait for it, you may wait forever because there will always be
something better yet another 12-18 months down the line!
