As Stephen Fox has pointed out in another thread elsewhere recently, tele-converters should only really be used with very, very good quality lenses. I know that if I use my t/con with my cheap Sigma 135-400 I get awful results. The two Tamron superzooms that Trinity is considering are very much convenience, consumer lenses (as Robski has already pointed out). I certainly wouldn't consider using a t/con with either of these lenses. If you need more reach later, there's plenty of 75-300 models that would do better than an 18-200 with a t/con attached.
Just my two penneth.
