telephoto for Pro70

James13707 · Jan 21, 2000

Is there a telephoto lens for the Pro70 that I can use for nature photography?

Thanks for any responses.

James,

I use the Kenko 2X teleconverter with my Pro 70. It's not a great solution due to vignetting and loss of image sharpness (a shame to compromise the excellent optics of the Pro 70). Here's a link to three shots taken with the teleconverter -- they've been cropped to get rid of the vignetting, sharpened, resized, and compressed:

The Kenko teleconverter is available for $39 from http://www.ckcpower.com and from cameraworld.com

Will also note that I used a circular polorizing filter with all three photos -- not sure I like the unevenness that gives to the color of the sky

Are there any converters to ive higher magnification, 4 X For example....

CKC Power has a Kenko 3X teleconverter, but they do not specifically recommend it for the Canon Pro 70. As bad as the vignetting is with the Kenko 2X, I believe it would have to be much worse with a 3X.

Also, Tom at CKC Power might test the Kenko 3X with the Pro 70 if you ask.

I emailed with Tom and asked about the Pro70, he said he will be working on having another lens made that will work with it.
