2X Teleconverter fora Digital Camera
Frank
(20D).
I have seen three which I have listed below. The price difference between
them is really significant. Opinions on any of them would be appreciated.
Quantaray-2X AF Teleconverter for EOS $79.95
Kenko 2X AF Teleplus MC7 Teleconverter for
Canon EOS $125.00
Kenko Pro 2X 300 Teleconverter Lens $239.95
My lens is a Canon EF 100-300mm f/4-5.6.
I assume the Pro 2X 300 is the best, but are the others worth having?
Thanks.

but it will be no faster than f/11 (2 stop loss in light), no more AF and
even on a tripod, you may be risking blur from the slightest motion. Putting
a 2x on a zoom such as your 100-300 will lead to soft pictures. I have found
that enlarging the image in a image editor such as Irfanview will produce
better results than a 2x on a consumer zoom.

Nikon 100-300 f5.6 lens. This combination is almost impossible to focus.
It is useless without a heavy tripod. When I used to one I owned then, the
tripod buckled at every joint. So, my advice is don't use any of the 2x
converters on your lens. But, if you must, buy the Canon.

>converters on your lens. But, if you must, buy the Canon.
The Canon converters won't mate with the lens he mentioned (Canon EF
100-300mm f/4-5.6), the front element of the converter protrudes about
half an inch so the only way to mount it is with a 12 mm extension tube
between converter and lens, meaning you lose focus at long distances.

Not to mention that you will loose auto-focus when you zoom as the
light level falls too low for the auto focus to work.
I have a Quantaray 2x and it's okay, but I haven't ever had a shot
from it that I really wanted to show off and the loss of light is a
horrible handicap.

excellent results as longs as you remember that your 400mm lens is now a
1280mm lens. Using such large magnification requires different techniques.
This even includes how much weight you place on your lens grip, the type of
tripod head (for instance I get better results when I use a standard 3 way
head as opposed to a ball head). I would suggest that you peruse some of
the shots at the Birds as Art Site and the shooter, Arthur Morris regularly
uses teleconvertors on large lenses. Yes, I loose auto focus but have no
problem with manual focus in most instance where I would wish to use the
lens with the converter. Quality wise, my good shots go to A4 no problems,
with or without the converter, my bad shots go to the trash bin. As a
budget solution its not a bad adjunct to your existing lens.

I'd buy the Kenko Pro 300 2x TC over the Canon, even if they were the
same price.
