D800 & strange bokeh
First portrait session with the D800 and take a look at the background: Natasha is sharp and in focus. Branches behind her camera right are what I would expect at f/5.6 (which is why I selected it). But take a look behind her camera left: What the heck? I've never seen that effect before. Other images from the session do not have this fault?/feature?  Camera: D800 Lens: AF-S VR-S Zoom-Nikkor 70-200mm f/2.8G ED Aperture Priority Focal Length: 116mm F/5.6 ISO 1800 Shutter: 1/125 Another from the session with 'normal' bokeh.  May 17 12 08:33 am Link That is really strange.. May 17 12 08:40 am Link Hmmm... this is scary. I think it is worth to send to Nikon for investigation. Is it possible there were some disturbances in the air creates this effect? May 17 12 08:49 am Link The strange bokeh of your first image was caused by VR-on mode. Nikon has said many times in the past that you should turn the VR OFF when shooting over 1/500s handheld. If you shoot under 1/500s, you should wait for VR to stabilize the image first before clicking the shutter button. May 17 12 08:55 am Link mshi wrote: I shot at 1/125. I am not a spray and pray shooter and have never seen this before. But it is a consideration. May 17 12 09:03 am Link Connor Photography wrote: I may just do the Nikon question thing.

Just passing through..at the time of your shot. Ignore it. lol May 17 12 09:08 am Link mshi wrote: Okay, IF it is a VR issue; why is only the background affected? It goes to just to the camera right side of her head but the hair is crisply focused. May 17 12 09:08 am Link I experienced a very similar, though not quite as pronounced, effect just once using a D700 with a 105 DC lens. It was also in a wooded area with trees behind the subject. I never did figure out what happened and I haven't had the issue since. May 17 12 09:14 am Link Creative Concept Studio wrote: the bits that are weird are in the near background. the normal or expected blur are in the far background. anything could be happening in between the subject (in focus) and the near and far backgrounds to cause differences. May 17 12 09:14 am Link I had similar issues with 70-200 VR I and I shoot with D3, mostly happened if you have branches & leaves as a background. What I do is adjusting/increasing the distance between the two by moving further away and I'm good to go ... Don't have a scientific explaination to it but I think, it's just a bad combo between the technical/pyhsyc of the lens with VR, F/stop and the given distance between background & model ... There are just too many things happened here ... you can't really blame the camera since the 'bad bokeh' effect did not occur on every image ... my 2 cents ...  May 17 12 09:27 am Link There is evidence in the posted image of the distortion on both sides of the image background. Since it is not a repeated effect then it is either something that glitched with the camera / computer on that one frame or it is something that was optically generated and the camera recorded it faithfully. Moire albeit a bit wierdly ? ( I realise this is not the D800E ).

May 17 12 09:31 am Link This is very strange... so the lens could be causing this? I have never seen this before. May 17 12 10:39 am Link Just for the record... I'm quite sure that fuzzy gray shit on the left side of the image is in the foreground... NOT the background. Background bokeh is on the right of the image... May 17 12 10:43 am Link I'll be very interested to know what Nikon's conclusion on this? May 17 12 10:51 am Link Select Models wrote: fuzzy shit is behind the model. how can it be in the foreground? its eclipsed by the model. if it were FG it would eclipse her instead. May 17 12 11:00 am Link AVD AlphaDuctions wrote: Wrong... see how the gray fuzzy shit is streaming thru a section of her hair... and also a line of it running vertically down her dress. Impossible for that to be in the background and accomplish that characteristic...

May 17 12 11:13 am Link It looks like it's in the foreground to me to, is it possible that there was a small twig bobbing in the wind? May 17 12 11:15 am Link Berghammer wrote: Yep... you saw that too huh... yeah... I think the OP is just trying to fuck with our heads... May 17 12 11:16 am Link Yeah, foreground movement on camera left. Looks pretty bizarre... May 17 12 11:31 am Link Do you have long hair? It looks like your locks may have fallen in front of the lens. May 17 12 11:33 am Link appears you were shooting pretty close to the model - and the foreground branches were *very* close? VR 1 version of the lens? If so I have seen that before, and it will occur very rarely and only with VR active I have shot over 1000 images of models in wooded themes with the D800 with no strange effects visible, including shooting *through* close leaves and branches.... May 17 12 11:47 am Link With its 36MP, it looks like the D800 is able to capture paranormal phenomena  May 17 12 12:00 pm Link If you look at it long enough it looks like blurry black birds. Recently I've been hearing something about angry birds. May 17 12 12:15 pm Link Sorry for the delay; I went back to the other images and found nothing until I dug up the discards - yup - it was a branch in front of the model. I don't ever do it and didn't think about it. Sorry for the confusion and thanks everyone for your help. May 17 12 12:18 pm Link Creative Concept Studio wrote: BINGO... where's my door prize?...

Looks like something in the foreground that is OOF rather than bokeh. may need to consider a possible lens issue before I'd sweat the camera. I see some OOF elements in front your model. Look around her hair on both sides of her body. Mostly camera left but I see a single "thing" camera right along her body. Maybe the aperture blades did something funky.

You just have some very high contrast texture in the back of the sun hitting the rough bark of the trees and at 5.6 you are not blurring it enough. VR does not affect bokeh in any significant manner.

. I think it is worth to send to Nikon for investigation.
