Entry Level Digital SLR Buyer’s Guide 2005
If you
already have some SLR lenses that are of good quality
(total value over $500 and are less than 5 years old) for a specific camera
make then the decision is simple.
All of the
cameras that are suggested below have the following specifications:
- 6 Mega Pixels (unless noted
otherwise)
- Compact Flash card storage for
images. (Compact Flash memory cards are the fastest, cheapest and can hold
the largest number of images. They are larger than most other types of
memory which is good because most of the other types are so small that
they can easily get lost.)
- 1.5X to 1.6X lens factor (which
means that the a 35mm film negative is larger
than the digital image sensor that captures the image by 1.5 to 1.6 times)
- Proprietary rechargeable
batteries (This means in case of an emergency, you can not go to a grocery
store and get more batteries for your camera – an unfortunate thing)
- They all save images as JPEG,
RAW and RAW + JPEG. (JPEG can be viewed with any program but the image
quality is not the best that the camera can produce. RAW is the best image
that the camera can produce but it must be opened by special programs that
can read the RAW file for your camera. All cameras will ship with a RAW
file reader.)
- Built in flash
- Auto-focus
- Compatible with lenses for the
manufacture’s 35 mm SLR cameras
- Advanced light metering
- Automatic settings for shutter
speed, aperture and white balance
- All of these cameras are faster
than regular digital point and shoot cameras and nearly as fast as a low
end SLR
- All of them have excellent
image quality up to at least ISO 200
The Candidates
Canon Digital Rebel XT

8 Mega
pixels
Great
upgrade path with cameras ranging from under $1000 to $8000

Very small
and light weight camera
Excellent
image quality up to 1600 ISO
Con:
Pentax is
not as well supported and established as Nikon and Canon with a limited digital
SLR product line
Starting New:
There is
also a good argument for starting fresh without regard for existing lenses and
other accessories that you may have.
Lenses:
- Amateur digital cameras capture
the image on a digital image sensor that is smaller than a 35 mm film
negative. The advantage to this is that they can use smaller and lighter
lenses.
- The lenses that are made
specifically for digital cameras are designed to shine the light at nearly
90 degrees to the digital image sensor which is required for an optimal
image (this is not an important requirement for film).
- Digital lenses are designed to
minimized the reflection of light off the digital image sensor which is
much more reflective than film
Flash:
- Some manufactures (most notably
Nikon) have created new flash systems that are optimized for digital
photography so you may want to get a new flash anyways
- All of the cameras that I have
suggested have built in flashes that work very well
- Most amateurs spend little
money on a flash so it is best not to make a camera purchase decision
based on the flash that you have.
Nearly all
other accessories in your camera bag are either less than $50 or are universal
and can be used with any camera which means you should not make your purchase
decision based on them.
Suggested Cameras:
I would shy
away from Nikon. They have good cameras and great quality but they are behind
the technology curve in the entry level dSLR and most
armatures will not benefit from the things that make Nikon great. (This is
coming from someone who is a huge Nikon fan so it says a lot).
Canon Digital Rebel XT or Minolta 5D. At this point Canon makes the best digital SLRs
and they have little competition. The digital rebel is going to work for you
for a long time and any accessory that exists will be available for a Canon.
The only problem with it is that lenses for a Canon cost a few dollars more and
if you want vibration control you will need to get it on the lens which is
costly (See below for info on Vibration Control).
The camera
that I am suggesting to armatures at this point is the Minolta 5D because the
vibration control is built into the camera. The image is very good and it is
simple to use. The only problem with Minolta is that it is not a Nikon or
Canon. Not all accessories are made for Minolta and they have only been in the
DSL business for a year or so. Both are things that I would not worry about as
an amateur. If you think you will be moving on to bigger, better cameras in the
near future go with the Canons that have digital cameras in nearly every price
range.
Vibration Control – This technology has many
names and ways of solving the problem of camera shake. (Canon calls it IS,
Nikon calls it VR, Minolta
calls it AS). The basic idea is the same, find a way to eliminate the
hand/camera vibration of the photographer so the image does not come out
blurry. For example if you take a picture from a moving car the image may be
blurry because your hand shook. With vibration control, the lens or the camera
compensates for the vibration and the image is not blurry. It can let you take
photos without a tripod and does make you a better photographer because you
will have less blurry images. What it will not do is remove the blur of a
moving object. So if you take a photo of a moving car that is going really fast
the vibration control will not remove the blur because it is not caused by the
camera motion. This is a very cool piece of technology. Canon, Nikon and Sigma
have the vibration control built into the lenses that they sell. Minolta has it
built into the camera so it will work regardless of the lens that you have,
which makes it a lot cheaper.
My
suggestion would be to go with the Minolta 5D and the Tamron
Zoom 18-200mm f/3.5-6.3 XR
Di-II LD Aspherical (IF) Macro Lens Digital SLRs with a UV or skylight filter to protect the lens
(Given a lens factor of 1.5X the Tamron is equivalent
to a 28 mm – 300 mm lens on a film camera). Get a 1Gig
(x12 or higher) compact flash card and expect to pay about $100. I would
suggest you take a look at the camera at a store and decide if you want to buy
it there or on line at a place like www.bhphotovideo.com. A good
camera store will give you help and support that is well worth the extra price
that you will pay over an on-line retailer.
Other Options:
If the
reason you want a digital SLR is to have a fast digital
camera with great image quality and a good lens then you may find out that you
do not actually need an SLR for that. After all, most
people who own an SLR never change the lens or they
change the lens because their zoom lens does not have wide angel apx 28 mm or go up to a zoom 300 mm. If that describes you then you may want
to reconsider the idea of a digital SLR because they
are larger and heavier than the alternative and cost more.
Welcome to
the world of ZLR which are cameras that look like an SLR but have an integrated zoom lens that range between 28mm to 300mm zooms (35mm film equivalent). Most of these cameras can also
accept lens attachments to get a wider angel image or a larger zoom so in some
ways you can still get the benefits of an SLR without
some of the hassles.
Given that
this is an article about dSLR cameras I will not go
into too much detail but I suggest you take a look at the following ZLRs which may be exactly what you are looking for and
more.
Nikon Coolpix
8800 (Vibration control,
8 MP, 35-350 mm lens)
Fujifilm S9000 (9
MP, 28-300 mm lens, and image quality as good as film)
Minolta DiMAGE
A200 (8 MP, 28-200 mm lens,
vibration control)
