tom_luongo1 Posted January 17, 2008 Share Posted January 17, 2008 I'm noticing a some purple halos on out-of-focus edges in the foreground and green on out-of-focus edges in the background. I'm pretty sure this normal for the 85/1.4 wide open (based on the Photozone review) But it seems like an undesirable quality for such an expensive piece of glass. I really like the build of this lens but I'm pretty sure that I'm going to send it back. Does anyone else have specific experience using the 1.4?<div></div> Link to comment Share on other sites More sharing options...
tom_luongo1 Posted January 17, 2008 Author Share Posted January 17, 2008 Another image. Link to comment Share on other sites More sharing options...
marke_gilbert Posted January 17, 2008 Share Posted January 17, 2008 Normal, mine does it as well, although Ive never seen it quite to this quite to this degree. Link to comment Share on other sites More sharing options...
tom_luongo1 Posted January 17, 2008 Author Share Posted January 17, 2008 Thanks Marke. These are fairly tight crops. On the full-frame image, the purple-green isn't obvious on If I return it, I'll likely get the 1.8 There is an earlier discussion comparing the two here - http://www.photo.net/bboard/q-and-a-fetch-msg?msg_id=005Y11 Could you tell me if the focus scale window in your copy has any looseness to it?<div></div> Link to comment Share on other sites More sharing options...
leicaglow Posted January 17, 2008 Share Posted January 17, 2008 I was recently told by a moderator that it's because of the sensitivity of the camera sensor. Mine, in particular, is a D200. You didn't mention which camera you have. Link to comment Share on other sites More sharing options...
ellis_vener_photography Posted January 17, 2008 Share Posted January 17, 2008 looks like chromatic fringing. Both Lightroom and Adobe Camera Raw 4.x have tools to take care of this but you have to shoot raw. Link to comment Share on other sites More sharing options...
eric_arnold Posted January 17, 2008 Share Posted January 17, 2008 whoa, look at that bokeh! that's why it costs $1k. Link to comment Share on other sites More sharing options...
tom_luongo1 Posted January 17, 2008 Author Share Posted January 17, 2008 Yes, it looks like chromatic fringing. But notice that it surrounds the character 'a' as well as filling the interior of the same character. Chromatic fringing would be to one side or the other of an edge but not both.

walterh Posted January 17, 2008 Share Posted January 17, 2008 "whoa, look at that bokeh! that's why it costs $1k." Exactly why you need several lenses - keep the f1.4 and ADD the f1.8 ^^. Another possibility would be to get the 105 f2.0 DC. You get fewer problems but get the nice bokeh. Link to comment Share on other sites More sharing options...
juanjo_viagran Posted January 17, 2008 Share Posted January 17, 2008 double the motion for the 105mm 2D DC lens.. WHAT A AWESOME LENS, I had it and now have the 85mm 1.4D but IMO the 105 2D DC is unbeatable, even w/o touching the DC. Link to comment Share on other sites More sharing options...
briany Posted January 17, 2008 Share Posted January 17, 2008 Ellis, that's the second time recently I've seen you say that ACR can correct longitudinal chromatic aberration. It can't, as lens designer Brian Caldwell points out here: http://www.photo.net/bboard/q-and-a-fetch-msg?msg_id=00NGVm Tom - lateral chromatic aberration would cause red/green on opposite sides of a contrasty object - basic red and greeen don't get magnified the same amount, so you don't see it in the middle of time image, but you notice it at the edges. Solution - shrink either the red or green image to make them the same size - easily done in software. Stopping down the lens has no effect (aperture has no effect on magnification). This image has longitudinal chromatic aberration - same colors don't get focused to the same point. So you get the problem in out of focus areas, across the image -- here red in front of focus, green behind point of focus. Much tougher to correct in software. But you can help alleviate by stopping down the lens (smaller apertures make depth of field greater). I'm not an optics guy.

marke_gilbert Posted January 17, 2008 Share Posted January 17, 2008 Yep scale window is slightly loose. Link to comment Share on other sites More sharing options...
frank_skomial Posted January 17, 2008 Share Posted January 17, 2008 I was trying hard to achieve result similar to your "aiwa" picture with my 85/1.4 AF Nikkor lens, and was not able to get your color deviated image on D200. I do not think this is the lens propertly in general ?, it could be more specific to your lens specimen and the CMOS sensor? Possibly your lens was subject of a "heat shock" ? or abuse ? Did you get the lens used or new ? Link to comment Share on other sites More sharing options...
tom_luongo1 Posted January 17, 2008 Author Share Posted January 17, 2008 <p>Frank, were you shooting at f1.4? Needs to be a high contrast subject. In my case, I was shooting near the minimum focus distance too. I'd be interested in seeing your result. <p> New lens from a reputable New York store. Better than average symmetry on the aperture blades when stopped all the way down. <p> The <u><a href="http://www.photozone.de/Reviews/Nikkor%20/%20Nikon%20Lens%20Tests/220-nikkor-af-85mm-f14d-review--test-report?start=2">85mm f1.4 review at photozone.de</a></u> has two sample photos that show similar fringing. See the statue photos. <p> I used it for some portraits earlier tonight but just got back and haven't looked in detail at the results yet. <p> Brian, thanks for the links. I'm aware that the effect goes away at smaller f-stops. But other than a brighter viewfinder, that would eliminate the advantage of an f1.4 lens. <p> Link to comment Share on other sites More sharing options...
bmm Posted January 18, 2008 Share Posted January 18, 2008 Juanjo - interest in your comparison between the 105mm and its 135mm sister. Are you an equal fan of both lenses? Link to comment Share on other sites More sharing options...
