Nikon 180 f/2.8 ED-IF AF D vs. non-D

greenspun.com : LUSENET : Camera Equipment : One Thread

Anyone heard of any discrepancies in performance between the D and non-D version of this lens? I have a weird recollection of someone complaining that they had taken a great lens and diminished it with the D-version, but that might be my imagination

Thanks

There is someone who has done Nikon lens reviews, I think who goes by the name of Grumpy, who was upset about a percieved decrease in quality in the newer 80 to 200 2.8 D zooms from the earlier series, but I haven't heard anyone complaining about the newer 180 AFD being inferior to the earier version, as indeed they are identical optically. I posted on photo.net a while back that I had a non D 180mm that focused very slow, but I think this was do to the lubricant drying out and getting dusty.

Hi John, As far as I know, there is no optically difference between the AF-D, AF non-D and the MF. My Nikon book says, all have the same glass. And there shall be no difference with the AF speed between the AF-D and non-D. All version I know have the same motor. Regards, Ralf.

All AF models of the 180/2.8ED share the same optical formula, with 8 elements (of which one ED element) in 6 groups, and a close-focus distance of 1.5 meters. The manual-focus ED AIS model has 5 ungrouped lens elements and focusses down to 1.8 meters.

Just I had a look at Nikon Germany. Mark is right, my book seems to be wrong. The MF has 5 ungrouped elements. Sorry for the mistake, Ralf.

Thank you all for the input. It was very helpful. I probably was thinking of the Grumpy review of the different 80-200 versions.

Thanks
