Hello Ron,

You seem to get some very good IQ with the Sigma 2.0tc and the sigma prime. You have gotten me interested in the Sigma 2x for use with the Sigma 500/4.5. I had more or less written the 2.0tc off, because I felt the IQ would suffer too much, but I now am having very good results with the 1.4tc, and your samples leave me in doubt. Did you try the 2.0tc with the 500/4.5? Is that also as good? Would be wonderful to have 1500mm eq. as an option.
