Two unrelated questions -
With TCs, do the VR versions play better than the original AF-S and AF-S II?
What about the old AF screw drive? Anyone shoot with it?
Thanks.
The optical qualities have not changed Soci would imagine the iq to be similar. I shoot with the AFS II and with the TC 1.4 and 1.7 I can see almost no loss in AF speed and IQ.
You can't put the current AFS converters on the old "screw-drive" type af lens without filing down a part of the mount. After the modification, the AFS converters will transfer the data, but the af will not work. The "standard" 1.4x for the old-style screw-drive 300 f2.8 is the TC-14b. This was a great combo in its day, but the newer AFS through VR designs are sharper.
