Teleconverters - Brands/Prices/Quality

I'm interested in a teleconverter to extend the range of my Canon FD 70-210/f4 on my Canon AE-1 Program. I've never used one before, but it seems like a relatively inexpensive way to add some focal length. Any advice on advantages/drawbacks, brands, types, etc?

<p>

Seems like the Canon made ones are pretty expensive. Anyone know much about the Tokina, Vivitar, or other brands?

Thanx for any and all advice.

Check out the camera and lens reviews on the classified page

I have the same FD 70-210 and also a Tokina 2x converter (don't know the model No. but it appears to be at least 3 elements/groups). I have not used the converter in 8-10 yrs, mostly because I was so dissatisfied with the image quality. I should caution you that this could be for any number of reasons other than quality of the Tokina:

<p>

1) I'm more than a little picky--I also can't abide by the resolution of the 70-210 when used in macro mode. If you are happy with your macro resolution you may also be happy with extender (and you're probably a little less anal than I).

<p>

2) I have a bad habit of shooting hand-held at FLs/speeds where I have no business doing so.

3) My tripod at the time was a flimsy piece of....

<p>

If we get some decent weather next weekend I will try a few shots w/ this combo and let you know what I find. In the meantime, you might want to consider an older FL lens. Both the 300 and 400 were introduced near the end of the FL run ('69 & 70 respectively) and are reputed to be pretty sharp. Plus, you lose one stop instead of two.
