But doesn't that make sense? Reports are that a 1.4x produces acceptable IQ (it may be a little worse, but it is acceptable). Additionally, reports say that the IQ degradation of the 2x II is unacceptable. Therefore, you are not going to get much of an improvemnet on the 1.4X III since there was not that big of a hit on the IQ with the 1.4X II to begin with... so there was not as much room for improvement. But the oppisite is true of the 2X III, where the 2X II left a lot of room for improvement so it would be easier to see a difference if they brought the 2X III up to acceptable IQ.

I think there is always room for improvement, but with the supertele’s the 1.4x II does extremely well. I tend to overdue things, when I got the 1.4x III I set it up on the tripod and bench and tested it to death.

One of the things I didn't mention the 1.4X III is that my AF was off using it. Where my AF is dead on with the 1.4x II I would have needed to do an adjustment with the 1.4x III. Since I couldn't get improved IQ results with manual focus on the bench, I didn't see the point in keeping it. I will get the III once the supertele II's come out.
