What causes this effect?

[heydn62]

What causes the ghosting in this photo? Particularly noticeable around the lower Oriole and the bright orange frame of the feeder. Shot with Nikon Z7 / Sigma 150-600 at 420mm - f8 / 1/1250. AutoISO at 12800. Handheld with Hood in use. The sun was low and out of the frame, up and to the left. Image is an edited JPEG from original RAW file and cropped to 2048 x1365. Ghosting was more prominent before editing.

Do you have a Clear UV filter attached? They will do this sometimes.

It took me several seconds to find what you were worried about - so to help me & others I have added a crop below ...

At first glance I thought that the 'blooming' might be an unwanted function of the high ISO ... but it's not that - as it's a distinct set of parallel images, seemingly as though there's been camera / subject movement. =but= at 1/1250s that should not be recorded

Stumps me ... over to others here

Improper use of VR? 1/1250 @ 250mm really doesn't need it.

Definitely movement.

Thanks for the replies. I did have VR on (OS on this lens - using setting 1). Maybe it would help to turn it off, but it was on the whole time I was shooting at this sight, and only a few photos had this effect - all shot at this same view. No filters on the lens.

I've been told that VR should not be used at higher shutter speeds, like faster than 1/500. Makes sense, because what it's for is stabilization of longer exposures.

 

[heydn62]

I usually leave it on because I often push down to slower shutter speeds when I need the light, and I've not noticed any poor performance at faster speeds before. I wish I had thought to turn it off when I noticed this happening so I could see if that was the difference.

Stabilization works differently on different cameras and lenses. The best approach is to turn it off when using a tripod, and if you are hand-held, turn it on for a few then turn it off for a few. A good practice for handheld in general is "change something and re-shoot".

Good advice. Thank you.
