Matthew Brennan Posted February 12, 2008 Share Posted February 12, 2008 I have searched the archives here and can't nail down a thread on the differences between the AF and AF D 85mm f/1.8 Nikkors. Is the AF version just a matter of an optics coating difference only? Thanks in advance......... Link to comment Share on other sites More sharing options...
low light Posted February 12, 2008 Share Posted February 12, 2008 The AFD lens uses your cameras 3D matrix metering for flash and the AF dosen't. Link to comment Share on other sites More sharing options...
Matthew Brennan Posted February 12, 2008 Author Share Posted February 12, 2008 Thanks Anthony, so if I intend to use an 85mm f/1.8 Nikkor for available light exposures only, the AF version will suffice.....? Link to comment Share on other sites More sharing options...
low light Posted February 12, 2008 Share Posted February 12, 2008 I'm sure it'll be fine, I have the AFD version on my F100 and i've always had perfect exposures. I'm not sure if there's any optical difference between the two. Link to comment Share on other sites More sharing options...
Jerry_ Posted February 12, 2008 Share Posted February 12, 2008 The non-D AF 85mm f1.8 lens may, repeat may, be a couple of years older than the AFD version. Other than that and the D (for distance) factor noted above, the glass is the same in both lenses. Link to comment Share on other sites More sharing options...
pisq Posted February 12, 2008 Share Posted February 12, 2008 Ken Rockwell offers an explanation of the useful ness of D vs non-D (middle of page) on his site:<br><br>http://www.kenrockwell.com/nikon/7021056.htm<br><br> Optically they should be the same. He also reviews the 85mm f1.8D. Link to comment Share on other sites More sharing options...
mark_sirota1 Posted February 12, 2008 Share Posted February 12, 2008 3D metering is not only for flash (that's a remarkably common misunderstanding), but it's a pretty rare case where it makes any meaningful difference without flash. Near-field mid-toned subject in front of a bright overcast sky is one likely example. Link to comment Share on other sites More sharing options...
bruce_rubenstein___nyc Posted February 12, 2008 Share Posted February 12, 2008 The AF of the D versions is faster due to differences in gearing in the lenses. Link to comment Share on other sites More sharing options...
