help-bizarre happening with 1DX and canon 50mm/f1.2L
« on: September 03, 2012, 08:01:58 PM »
Hello all, first time caller, long time listener.  Looking at a couple of shots from yesterday, i noticed a very strange sensation on some shots taken with a 1dx and a canon 50mm f/1.2L.  I've never quite seen anything like this before.  color Ghosting around the gentleman with the flyer over his face and that rainbow line across the the back of the cameraman's head.  Both the lens and body are new.  Any insight would be greatly appreciated.

back of the head is at 100iso 50mm f/1.e 1/1600 sec
man on stoop is at  100 iso 50mm f/2.8 1/500 sec - the effect around his right arm is particularly baffling.

Both are exported as shot with not correction of any sort.

Not sure what that color ghosting is from, that is really strange.  but I can definitely tell you that the rainbow flare is from not using the hood, or from light hitting the side of the front element...

If you see the whole frame of the cameraman... you'll also see, nothing specular in that shot.  No evidence of sun coming thru onto anything, so I'm guessing.... its not a flare. 

Just doesn't look like flare either.  Have a look at the full frame of that image.... I dunno....(still considering things)

Do yu have the lens correction feature turned on for in the camera?  That ghosting looks like its over correcting chromatic aberration.  Either way, it shouldnt do that.

doesn't look like anything i've seen from a lens/filter/sun issue. looks like digital hijinks to me. I hate to say it, but if i was you i'd get in touch with whoever i bought that camera from and talk about getting a replacement.

Wow, that guys jacket and pants are covered with Moire. 
It looks like the anti-alising filter is missing.
I'd send it back for repair both lens and body.

Is the 50mm also new?  If not, I'd just exchange the camera.  If both are new, it would be worth figuring out which one is the culprit.  That moire is definitely excessive.  If I spend that much money on a camera, I would want one which works right out of the box and doesn't have to be sent in for repair right away...

If this is true, don't send it back. Sell it on eBay as the new Canon 1DxE for $1000 over the normal price!

I test the 1D X with my EF 50 f/1.2 L and get perfect results. Send it in for repair.

Anybody else notice the complete lack of EXIF data on the images?  Are they really from a 1D X.  I haven't seen anything come out of my 1D X looking like that and I too own a 50/1.2L...

I did notice the largest images posted are significantly smaller than the 1D X's s-raw-size of 2592x1728. I'm assuming resampling here, which probably caused the moire. Without knowing which software was used to what extent, can't say I'm suspecting the camera or the lens of the eerily discrete 'ghosting' area either.

And about the flare: that would be flare. If all flare would be controlled, we wouldn't have enough UFO sightings :)

That appears to be moire on the jacket. The slice looks like flare but not from the lens, perhaps this is a defective AA filter thats causing these problems.

Yes they are indeed from a 1dx.  For some reason the metadata is not transferring to flickr.  Just so there's no questions about the authenticity I'm posting a couple of screenshots from lightroom 4.1 with the metadata. 

I must admit I'm pretty shocked by this happening.  The 50 f/1.2 is not producing this effect on my other bodies.  It is a new lens, perhaps it is the combo of lens and body.  I did know going into the purchase that the lens did have a reputation for strange and often annoying "behavior" but these happenings are a little bit more than I expected. 

I suspect that the problem could be with a faulty anti-aliasing filter.  I'm going to attempt to return the body to the local dealer I bought it from 15 days ago.  Hopefully they'll take it.

I'm a little miffed with Canon's track record as of late.  Seems the last few bodies I've bought have had problems out of the box.  It's a real shame.
