Extension Tube is a really fun and inexpensive accessory to
purchase. It extends give or extends your lenses ability to take
Macros. Depending on the focal length of the lens you attach it
to, and the distance between the object and the lens you will get
different magnification factors.
The photos above are
three examples of macro photos taken with the EF12, The two small
flower photos are actually the same type of flower. The image on
the left was shot with the EF12 attached to the 24-70mm zoom.
This gave an approximate 1:1 image. The 24-70 actually has close
focus (macro) capabilities on it's own and the EF12 was probably not
necessary in this situation, but it is always fun to use, just in case
you want further magnification.
The orange flower is an
example of this. This was also taken with the EF12 attached to
the 24-70mm zoom, but this time I was much closer to the flower and it
produced a 1:2 magnification of this flower. In actuality the
orange flower was about half the size as it appears in the photo above.
The small flower photo on the
right is the same type of flower as the one on left. This
time I used the EF12 in conjunction with the 16-24mm zoom. This
allowed me to get much closer to the flower and get a much greater
magnification as well. This image is a 1:4 magnification of the
flowers actual size.
You can also use the EF12 with
the 70-200mm zoom, but this gets quite cumbersome since that lens is
pretty large and heavy. Also, you don't get much magnification,
so I have found no reason to use this combination.
If you enjoy macro
photography, I highly recommend adding an extender to your
accessories. You can get other extenders that give you even
greater magnification. All the extender actually does is increase
the space between your lens and the camera body. It is actually
just a spacer. It contains no glass. The larger the space,
the greater the magnification. These accessories only run around
$70. I think they are the best value for the fun you get out of
I must add that all of my
images have gone through Photoshop. I
crop, sharpen, employ noise reduction techniques, adjust contrast,
saturation, and sometimes tone on most of my photos. Out of the
camera the images don't look as good, but in my opinion this is the
great benefit of the digital world. I believe that you should
take all of your favorite images and mess with them in Photoshop.
But remember, in photography your photos will only be as good as your
weakest piece of equipment. If I was shooting with a lesser
camera and with inexpensive lenses I would not have been able to
achieve the quality of photos shown above, even with the help of
