Sigma 85 1.4 and teleconverter?
Is there a 1.4 or 1.5 teleconverter that I can use with my Sigma 85 1.4 and Canon 50D that will allow the lens to opperate "properly" (i know that it will lose light, but i would like for all the other features, such as the autofocus and the aperature to still work automatically). Thanks!
My Kenko 1.4x works on my Sigma 85 1.4, but interestingly enough doesn't seem to report its existence. It still shows as 85mm f/1.4, rather than 119mm and whatever one stop down from f/1.4 is (f/1.8?). Slows down AF, but overall works fine (although not quite as well as it works on my 70-200 f/4 IS). Haven't taken any keeper shots with the combo, so nothing I can share - sorry! --Erik
