joie_puckett Posted October 11, 2002 Share Posted October 11, 2002 Hello, I have this brand new 50mm 1.4 af-d lens [bought from adorama-usa model] [made in china] that is giving me weird lens flare in an otherwise normal shot. overcast day, no sun, shot at 1/1250sec at 1.4. look at the weird halos on the hats. I am not sure whether or not to return the lens. I have heard that there are cheaply made 50mm nikon lenses out there, thanks. joie puckett<div></div> Link to comment Share on other sites More sharing options...
gannet___ Posted October 11, 2002 Share Posted October 11, 2002 Is that on a print? Neg? Slide? Be sure it's not a processing/printing issue first. If it's not, then send it back. But it looks to me like it probably is. Link to comment Share on other sites More sharing options...
steven_j Posted October 11, 2002 Share Posted October 11, 2002 It looks like the lens was slightly fogged. Did you go from air conditioning to a hot, muggy outside. There may be haze inside the lens, too. Is this the only image that it happened on? Link to comment Share on other sites More sharing options...
jim_gifford Posted October 11, 2002 Share Posted October 11, 2002 It isn't the lens, it's the guys, just exuding that healthy glow of hard work and purity of spirit. Well, okay, maybe it IS the lens. But a fault in a lens should be consistent, so I'd say try another roll or two (promptly) before asking Adorama to replace it. Link to comment Share on other sites More sharing options...
joie_puckett Posted October 11, 2002 Author Share Posted October 11, 2002 Thanks so much for the response guys. I can give you more information. I live at the beach and we have no air conditioning, so the environment isn't a factor. It was a normal day in Long Beach, CA... no extra-normal humidity, etc..... Also, the shot was taken with a D1X and uploaded directly... -joie Link to comment Share on other sites More sharing options...
sorin Posted October 11, 2002 Share Posted October 11, 2002 I own the Non-D version of the lens and I've never been impressed with the performance of the lens wide open. By contrast, my Nikkor 80-200 2.8 behaves beautiful wide open. I though my sample was bad but apparently it's not. The lens behaves MUCH better at around f2.

craig_bridge Posted October 11, 2002 Share Posted October 11, 2002 D1X Whoa! Don't blame the lens! You've probably got pixel bleed / Jpeg migration. You need to keep the highlights from going way off scale. If you still have the image in a form you can put it back into the camera, scroll over to the blinking blown highlights view. The affected areas should be adjacent to some major blinking if I'm correct. Link to comment Share on other sites More sharing options...
charles_miller Posted October 11, 2002 Share Posted October 11, 2002 Judging from the depth of field, I don' think you were shooting the lens wide open, and my non-D 50mm f1.4 AF never did anything remotely like that. Right now, my best guess is also "pixel bleed". Link to comment Share on other sites More sharing options...
david_kelly1 Posted October 12, 2002 Share Posted October 12, 2002 Darn these guys' technical smarts! I knew what you had was was optically impossible and was hoping that this would turn out to be a case of "Inappropriately Touched By An Angel"............

Especially from guyswith the same lens who've never had the problem.<p>The D1X has no problem whatsoever with pixel bleed or jpeg migration. The ghosting is there in the NEF file format [RAW file that the cameracreates with no compression whatsoever]. The information on the shotis also recorded and the f/stop was indeed 1.4. The shutter speedwas high enough to stop the motion of the worker's heads, so I have ruledout motion blur...<p>The camera does NOT do this with other lenses.

I say 'whites' because it softens on white areas of the images.<p><b>I'm thinking this lens is just not sharp.

pete_su Posted October 12, 2002 Share Posted October 12, 2002 i have this lens. it doesn't do this. well, it did do it once, but that was because the UV filter i had on the lens needed to be cleaned. Link to comment Share on other sites More sharing options...
charles_miller Posted October 12, 2002 Share Posted October 12, 2002 "The camera does NOT do this with other lenses. I have only had this happen with this new lens". Well, then of course you don't want to keep that lens. Either that particular lens is defective, or else that model has compatiblity problems unique to your digital camera.

ed_alban Posted October 13, 2002 Share Posted October 13, 2002 Shine a bright light through the lens, aperture ring set at f/1.4, from one end then the other. I once had to return a brand-new Nikon lens that had "streaks" (maybe polishing marks) and an obvious internal overall haze, despite flawless front and rear elements. The exchanged lens was much much better. Link to comment Share on other sites More sharing options...
george_dreimanis Posted October 16, 2002 Share Posted October 16, 2002 looking at the images I can see that the workmen are slightly out of focus. This adds to any lens deficiencies especially when you have such high contrast variations from the hat to the background. Link to comment Share on other sites More sharing options...
michael_devoue Posted November 10, 2002 Share Posted November 10, 2002 I think george nailed it. If it bothers you that much, get another (maybe used USA)example and test under very controlled conditions. Link to comment Share on other sites More sharing options...
