Re: true, but...

I've been reading through the thread in that link and looking at the examples. Its rather counter intuitive but it does seem that you get a wider field of view and better image quality WITH the 1.4 TC.

To quote one of the posters in that thread "The TC's front element is closer to the rear element of the 10-20 than a sensor would be, so it seems to be collecting more of the image circle than even visible on the FF+noTC example above, and magnifying it up to FF."

I recently bought the Sigma 10-20 4-5.6 and love it. I plan to move up to FF in a year or two and this discovery makes me even happier that I bought that lens!
