G10 teleconverter on 70-300 lens for t2i?

[Goatalope]

Going through the random camera stuff I've acquired, I found a TC-DC58 1.5x teleconverter for a G-series camera. Can I just thread that on the end of a 70-300 ef lens and will it magnify it 1.5x? Or will it just look crappy? Super zoom on the cheap? [h=1][/h]

Nearly all 70-300mm lenses don't perform well with teleconverters - one or two might just make it with a 1.4/5 TC but not with great results. A teleconverter based around an end of lens attachment and for a different sensor and lens size might not give you much of a result and you may get vignetting problems (that is dark shadows in the corners).

Really the only way to know for sure is to try it- but I wouldn't hold out much hope (I'll be happy to be corrected if you can get some test shots).

I'll give it a try once I get the lens, teleconverter and body all in one place (I'm in transition right now). Thanks.
