For this outline I will talk
about 35mm film cameras and the equivalent in
digital cameras because they are the most popular in
our club. That’s not to say you can’t be a great
photographer using a different format.
Camera
Bodies
35mm single lens reflex film cameras have
a wide price range; they start around $300 and go to
about $2000. The $2000 camera is designed for the
professional. They will have a metal frame, weather
sealing and are extremely rugged. Some of the
consumer cameras will have metal frames and some are
all plastic. You may hear or read a term “Pro-sumer”
this is a camera somewhere between the Professional
and consumer cameras. Some of the consumer cameras
have as many features as the high-end cameras. The
bottom line is finding one that fits your budget and
is comfortable for you.
Digital cameras are not as simple
as film cameras. The technology is changing so fast,
it seems like a new model is introduced every other
week. Camera manufacturers have pretty much kept the
same basic controls that film cameras have had for
years. This has made the jump from a film camera to
a digital a little easier. The price range on
digital SLRs is much greater than film cameras: they
currently range in price from about $700 to $1500
for consumer cameras and they go to about $8000 for
a top-level professional camera. Like computers
these numbers will be reduced as manufacturing
techniques change and improve.
If you plan to purchase a film or
digital camera take your time and talk to other club
member.
Lenses
If you had to decide between spending
extra money on a film camera or a lens I would
recommend the lens. I don’t think this statement is
as true for digital cameras. If you reduce the film
camera to its basic function’s setting the lens
opening and opening and closing the shutter all
SLR’s (single lens reflex cameras) that are working
properly will do this. Digital cameras play a bigger
role in image quality than film cameras. Lens
quality is so important for film and digital
cameras, so before purchasing a lens ask other
photographers what they have and if they are happy.
Some lenses have plastic mounts (the part that mates
to the camera) and some have metal mounts. Obviously
the metal mount will last much longer than the
plastic, so it depends on how much you plan on
changing lenses. For lenses that have the focusing
motor built in there are some differences in speed.
If you plan on fast action photography you should
consider lens-focusing speed. As with most things
that we purchase you get what you pay for.
Inexpensive lenses will not give you as good an
image as professional grade lenses. Most
manufacturers make several different grade lenses to
fit your pocket book. Get the best you can afford.
It may not be obvious to you when you look at an
image you have taken with an inexpensive lens until
you compare it to the same image taken with a better
grade lens.
Should you buy a zoom or a fixed
focal length lens? Good quality zoom lenses today,
can be as good as fixed lenses. This was not always
true, but with computer aided design this has
changed. So I would recommend a zoom lens for the
versatility you get. There are a couple of things
you should consider when purchasing a zoom lens.
First when buying zooms do you want a fixed maximum
aperture or one that changes the maximum aperture
when the focal length is changed. The fixed maximum
aperture lens will be heavier, larger and usually
more expensive. Professional photographers prefer
the fixed maximum aperture for a couple of reasons
but for most of us the smaller lens (of good
quality) will do very nicely. If you plan to buy
more than one lens you may want to purchase (if
possible) lenses that take the same size filter.
This will be cost effective and keep your camera bag
a little lighter.
I’d like to talk about Macro
lenses there are three basic sizes that are most
commonly used by photographers. The focal length may
vary between manufacturers. They are 50mm, 100mm and
200mm. There is a little difference in weight
between the 50mm and the 100mm but a big difference
between the 100mm and 200mm. If you use the 50mm for
a butterfly you will have to get very close which
makes this lens difficult to use in the field. The
100mm is a good choice, the distance from the
subject is better and they are usually lighter and
less expensive than the 200mm. The 200mm can be very
useful in the field but they are heavy and costly.
Some lenses have a so-called macro mode built into
them but usually they do not focus as close as a
true macro. There is a less expensive way to do
close up work, by using a close up filter. These
filters will screw onto your lens and they come in
different magnifications and in some cases they will
come in sets of different magnifications. Like
lenses quality should be a strong consideration.
Using an extension tube is
another way of gaining magnification. An extension
tube is not a lens rather a tube with no glass that
fits between the camera and the lens you’re using.
They are labeled in millimeters (mm) and may come in
various sizes like 12mm, 25mm etc. these numbers may
vary by manufacturer. What they do is let you focus
closer to a subject than the lens you are using
will. This will effectively increase the
magnification. These are great tools; if you put one
on a telephoto lens they are great for photographing
small animals and other small subjects.
Tele-converters are another
useful tool. They typically come in two sizes, 1.4X
and 2X. What they do is change the focal length of
the lens you attach it to. If you attach a 1.4X
converter to a 300mm lens (multiply 1.4 x 300=420)
it will be a 420mm. If you attach a 2X converter to
a 300mm lens (2 x 300=600) it will be a 600mm. Like
all lenses the quality of the glass is important.
I’ve owned both from my camera manufacturer, which I
think, are good quality. I have been very happy with
the image quality of the 1.4, it is outstanding but
the 2X was not as good as I had hoped.
Tele-converters may not fit on all lenses for
example my 1.4 has a protrusion on the front which
will limit its use. If you plan to purchase a
teleconverter it maybe a good idea to match the lens
or lenses you have, in other words purchase one made
by the same manufacturer as your lenses.
There are other lenses that have
recently appeared on the market which are
specifically made for digital cameras with less than
full size sensors. These cameras have a sensor
smaller than 35mm film frame. These lenses will only
work on specific digital cameras and may not work on
a future camera you may purchase.
The last thing I’ll say about
lenses is try to have a hood that fits each lens. If
you use the wrong hood on a lens you may get
vignetting (dark corners). The hood will protect
against flare and protect the front of the lens.
Equipment/Tripods
One of the most
important pieces of equipment you can own is a
tripod. When choosing a tripod the most important
consideration is its sturdiness. Other
considerations are height, weight and how low will
it go. If you are using your tripod for long periods
of time the less bending you do to look through the
viewfinder the better your back will like it. A
tripod that is tall enough for you without the
center column extended is strongly recommended. Also
if you plan to carry your tripod long distances your
back may not like a heavy tripod although a heavy
tripod is typically sturdier. So you may need to
make some compromises. Another consideration is
whether the tripod can be adjusted to get down low
for close up work on the ground. When you use a
tripod you can slow the whole picture taking process
down, this allows you to study your image before you
release the shutter. For some subjects you may want
to check depth of field this takes time so using a
tripod helps this process. For all subjects you need
to look the entire frame over and make sure there is
nothing in it you don’t want. If you need a slow
shutter speed it’s easy with a tripod.
There are all types of heads for
tripods some are small and light some are large and
heavy. If you plan to use long heavy telephoto
lenses you should get a head that will accommodate
them. Quick connect ball heads are very popular but
can be expensive.
Other
Equipment
Other equipment I would recommend, are
spare batteries, lens cleaning equipment and a cable
release or remote switch. I think these three items
are a must. A gray card is helpful for exposures,
which I will talk about in another section.
Film and
Digital Media
There are many types of film out there,
but I’m only going to talk about slide film, as it
is the most popular at our club. Film is rated by
speed or sensitivity to light (ISO), the faster the
film the less light it needs to make a correct
exposure. The most commonly used slide film today is
ISO 100. It is about the slowest speed film now used
and slow film typically is the sharpest and can have
the most accurate colors (for a neutral film). There
are two basic types of film, neutral and saturated,
with some variations. Neutral films give accurate
colors while saturated films will enhance or
saturate some colors. Not all saturated films have
the same effect on the same colors. Film also comes
in consumer and professional versions. Professional
versions require refrigeration while consumer
versions do not. Professional film is at its optimum
at the time of manufacture and refrigeration will
hold it at there until use. Professional
photographers need large quantities of film that
have the same characteristics when they shoot the
same subject. Most of us could never tell the
difference between one batch of consumer film and
another. It’s not a bad idea to try different films
and the settle on one that fits your needs for most
subjects. You may want to keep some other films on
hand for special uses, like a fast film. If you keep
it in the refrigerator it will slow the aging
process and putting it in a freezer it will stop the
aging process. Just leave yourself enough time
before use for it to reach room temperature. Try to
keep your film out of extreme heat.
The digital equivalent to film is
the digital card used to store the images. In my
opinion compact flash is best in terms of ruggedness
and cost, so consider the type of media used to
store images when you purchase a digital camera.
Fortunately, prices for digital media have been
dropping rapidly over the past few years.
Filters
There are many filters on the market today
and there are several manufacturers. The two most
commonly used types are screw-on and rectangular
systems. The screw-on type is pretty
self-explanatory, the rectangular system usually
consists of a holder, which fits on the front of
your lens, and rectangular filters slide into the
holder.
When I first started in
photography it was widely accepted that you should
have a skylight or UV filter on the front of all
your lenses to protect the glass. Many professional
photographers have disagreed with this; they say it
is another thing to cause flare or other such
problems. I agree a good way to protect your lens is
by keeping your cap on except when shooting or by
leaving a substantial hood on the lens. The only
time I use a skylight filter is near the ocean when
there is a risk of salt spray getting on my lens.
There are lots of different
filters out there but the only one I think all
photographers should have is a polarizer. The first
thing you have to decide when purchasing a polarizer
is whether I need linear or circular polarizer. This
depends on your cameras meter; your manual should
tell you the answer to this question. There are
standard and warming polarizers; a warming polarizer
combines warming and polarizing filters. Thin
polarizers are available for use on wide-angle
lenses but may not be necessary with your lens. If
you plan to purchase a polarizer and have a
wide-angle lens check the filter on the lens before
you purchase it. You will be looking for dark
corners (vignetting); this will show up on your
image.
You will probably add several
filters to your bag. If you do keep in mind they go
in front of your lens so quality is important.
