p.1 #1 · p.1 #1 · D810 w/ 4002.8..what am i seeing??


I was shooting the Golf Channels AM Tour in Scottsdale AZ this week and I came up with this odd, I dont know what to call it in "bokeh posterazation"...the background. Take special notice of the branches in the background. I have several other examples I thought I could almost see something different in the viewfinder something was a bit off. Earlier in the week I used one of my D3s's with the 400 and never saw anything like this. Any help would be appreciated. D810/iso100/f2.8/1/2500 with 400 2.8 vrii

Was your VR on or off. Sometimes VR can create some different bokeh, but this just seems odd in the picture above. It looks like the lens is stopped down but it isn't.

I'd suggest some controlled tests with your d3s vs the d810 to see if you can replicate it again.

I take it you are on a monopod?

Some images were on a monopod. I do handhold the 400 quite a bit but for the most these are on a monopod

Almost looks like heat wave diffraction

I know adobe just recently updated their programs to work with the D810. Make sure you are using the latest software to process your files. Another user had the same issue a few days ago and it was due to the raw conversion.

I tend to agree with heat wave diffraction. How far away were you and how hot was it?

I've had that happen in the past while shooting football,,,,,,, definately heat wave diffraction

I think I'm siding with DixonDuke and BenV. It just wasn't that hot out, however what does not make sense is that I noticed it thru the viewfinder at the time of capture, I could tell something was off and it looked off in the LCD when I chimped. ....so mabey it is heat diffraction. I'm testing more tomorrow morning and will report. Thx for the feedback !

shoot a similar shot with the same distances between you them and the background with the VR off. at the same aperture and speed.

I processed the RAW file with the new Camera Std v2 Beta and it changes the color gradation and smoothness but does nothing for the artifact looking stuff I am seeing in the background

FYI it doesn't need to be hot for it to occur - I see it a lot in winter actually. It only requires a temperature differential.

OK so if I go with the heat wave theory then why is it present with the D810/400 combo but not present on the D3s /70-200vr ii combo which I was shooting at the same time....are the heat waves more pronounced because of compression from the 400?

Most likely, yes.

I actually did a video on this problem a few weeks back. The video is aimed at nature photographers, but the idea is the same. Here's the link if you're interested:

Gents I stand corrected. After further investigation i see the same effect on images taken from the D3s/70/200 combo. The effect is not as pronounced as I believe the 400 makes it look worse because of the focal length and its compression on the background.
