>From Jostein> >After also using it with many other lenses, I have found that AF with the TC is very accurate with f/2.8 (or better) lenses. Precision with eg. M-200/4 is ok, but no more than that. Lenses of apertures darker than f/4.5 will make the AF hunt in low light. AF is quite fast. Comparable to eg. FA50/1.4.
The converter works even when using a f/4.5 like the FA 4.5/300 if you are using it with a MZ-S. The MZ-S AF has a far better low light abiltiy than the Z1-p or MZ-5n, this cameras have a problem with this lens. Regards R�diger
