I've got the Sigma 1.4X and it works fine with my 80-200 (collar version). One thing to keep in mind, the 1.4X converters are usually a lot sharper than the 2X. ------------------------------ Date: Wed, 27 Jan 1999 20:21:36 +0200 From: Alexander <[EMAIL PROTECTED]> Subject: TC for 80-200 2.8? [v04.n219/12] Message: 12 Hello, I asked this before, but I am not sure If my email went through. Is there a TC (preferably 2X) that will work with the 802-- 2.8 ED collar version? Looking at different sites on the net, I cant seem to find a match that will work properly. Thank you.
