50mm 1.4 af-d lens weirdness

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.

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...

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.

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.

<b>Photographer's comment #2</b><b></b>

<p>Wow, I really do appreciate the response.  Especially from guys

with 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 camera

creates with no compression whatsoever].  The information on the shot

is also recorded and the f/stop was indeed 1.4.  The shutter speed

was high enough to stop the motion of the worker's heads, so I have ruled

out motion blur...

<p>The camera does NOT do this with other lenses.  I have only had

this happen with this new lens.

<p>I am just looking to confirm that this lens ghosts on highlights/whites. 

I say 'whites' because it softens on white areas of the images.

<p><b>I'm thinking this lens is just not sharp.  Anyone else think

this as well, or have a contradictory story of a sharp 50mm 1.4 lens they

own?</b><b></b>

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.
