for Bird Photography
The new digital cameras make bird photography easy and fun.
To see some recommended cameras for bird photography go to
the camera store.
For those switching from film to digital here are answers to a few
questions many will have.
What is the difference in lens focal length?
This is probably the most asked
question. Most modern digital SLR cameras use a sensor that is
approximately 22 × 15 mm. In 35 millimeter cameras the focal
plane is 24 X 36 mm. Because of the smaller sensor size you
loose some of the wide angle.
Any focal length lens from a 35 mm
camera is the same as a lens 1 and a half times that size for a digital
SLR camera. That means that a 50 millimeter lens for a 35 mm camera is the same as a
75 mm lens of a digital camera.
This is why many digital cameras these days will come with an 18 to 55
which would be about like a 28 mm to 80 mm zoom in a 35 millimeter camera.
Many people will ask if they can use their old 35mm lenses with
a digital SLR camera. The answer is that in some cameras if the mounts
are the same you will be able to shoot with the old lens, but you will not
have any metering ability because there will be no contacts.
Is there a difference in quality between
film and digital cameras?
In film you are concerned with grain size to
determine how detailed your picture is. While there is no
direct comparison, in digital photography you are concerned with the
number of pixels.
The more pixels or spots registered in your image the better quality of
image. A six mega pixel image will look good if it is printed at 16
To illustrate pixels; below is a high resolution picture of
a waxwing head along with 3 parts of it enlarged 400 times.
Each color square that you see in the enlargements is a
pixel. A lower resolution or pixel count would make each
pixel cover more area and definition in the picture is lost.
For bird photography I would recommend the highest mega pixel
camera you can afford. They do get pricey at the upper end. I
would also suggest at least a 300 mm telephoto. The camera I use now
is the Canon EOS 40D.
My most used lens is a 70 to 300 mm zoom. Here are some tips
on bird photography.
Many film photographers use the grain in film to get different effects
in their photography. While the look is not the same, a grainier
appearance can be achieved in a digital camera
with higher ISO settings.
