telephoto for canon xh-a1

Ok, I've had a bunch of "salesman" try to sell me a telephoto for my XH-A1 so now I'm turning to those of you that really know. I'm currently filming wildlife for hunting videos and need to know which one will be the best for my application.

I know that 16X9 sells one for under 900 bucks that looks pretty good. I'd be careful of anything much cheaper than that.

Even using the more expensive teleconverter such as the one mentioned above will still degrade your image somewhat, particularly around the edges. Also chromatic abberation is increased substantially.

The stock lens is the 35mm equivalent of 650mm, which is pretty impressive and adequate for most applications.

I shoot some wildlife, and I'm very pleased with my
Century Pro Series HD 1.6X Tele-Converter 102mm.

I see no vignetting when zoomed in. When you
zoom out it's like looking into a train tunnel, so
know that you'll only be using it when zoomed in.

I find it's sharp enough for video.

Some thoughts: I recently started shooting video,
but I worked as a still photographer for print publication
for years. The required lens sharpness and pixel resolution
needed for high-quality printing (ink on paper) are greater
than the lens sharpness and resolution required for
display on a 1080i display.

I know this may be more detail than this post calls for, but
here's an example. For a four-inch high image printed on paper
to look sharp (glossy magazine, not newspaper rag), then
I'd want to start with 1200 pixels high (300 pixels per inch).
That four-inch high image in print rquires a greater resolution
than my Canon XH-A1 (1080i) can produce. I carry a 10+
megapixel still camera for still images, just because acceptable
still images cannot be made from the XH-A1 for my print purposes.

Yes, I know some newspapers are requiring their photographers
to shoot with HD video cameras (for web content), and video
frames are converted into still shots for print publication, but the
quaity in print is compromised. Oops, sorry, I'm off topic again.

Bottom line for video: I think the sharpness of the Century Pro
(and probably other high-quality video add-on lenses)
exceed the sharpness needed to look great on a HD display.
