p.1 #1 · D600 exposure varies between 2 shots same settings

No bracketing is not on. Same settings light does not change, focal length does not change and yet exposure differs by about 1 stop. Happens with different lens as well. Shooting raw. Any ideas what could cause this?

Different focus point? Matrix metering is heavily weighted to what's under the active AF point.

You're in M mode? Auto ISO off? No polarizer?

Are you shooting under fluorescent lighting? If you are, then the exposure will vary from shot to shot because of the cycling of the lights.

Try shooting a hockey game under that lighting and you'll have an exercise with frustration!

This is happening outside in normal daylight. No flash being used either.

Check if the aperture lever on the body is bent. You need to check it both from the front and the side.

Do you have dynamic highlight recovery or whatever that feature is called. Basically, it lifts the shadows on images and you can set it to automatic. Maybe that is doing it? Turn it off and see what happens.

The aperture lever look ok to me and I do not have any of the dynamic range, highlight stuff turned on. It may need a trip to Nikon.

How often is it happening and is it happening when you are shooting in bursts? This occasionally (rarely) happens to me while I am shooting wildlife on CH and I am firing off a burst of 3-5 frames, it also seems to underexpose in these instances versus overexposing.

Happens randomly and the camera is in single shot mode. It's not on CL or CH.

It would have been so easy if you had listed all the pertinent information in just one post.

This feels like playing detective, only just that you didn't share enough info from the beggining..

Anyhow, hope you get it sorted out

Thanks for you help. Didn't know what all the pertinent information was until persons started asking. Sorry to have bothered you.

Assuming there's nothing wrong with the sensor, the only way to get varying exposures in M from one shot to the next is if either the shutter or aperture mechanism is malfunctioning. Of the two the aperture is easier to verify. Shoot a scene with shallow DOF, where you'll be able to visually distinguish a stop difference of DOF. Take a sequence with the same shutter/aperture, using an aperture 1 stop away from wide-open. For two images with different exposures check to see if the DOF is different. If it is then the aperture lever is malfunctioning, otherwise it's the shutter.

Thanks snapsy. You may be onto something here as looking back on some of the photos the darker ones do seem a bit sharper which could be due to increased depth of field. Sending it off to Nikon next week.

One more thing to look at, if you're using spot metering, the tiniest of movement within the scene can cause a fluctuation in exposure.

Thanks Guari. I hope to figure this out today as after looking back at the last wedding it may be a lens issue instead.

Using matrix metering but even with spot meter the exposure would not change shooting in manual mode and not one of the auto modes. Auto ISO is also off.

p.1 #20 · D600 exposure varies between 2 shots same settings

Looks like the aperture lever on the 24-70 is the problem and not the camera. I was going from memory when I said different lenses. Another reminder not to trust my 40 odd year old memory lol.

The aperture lever on the 24-70 does not move freely and snap back into place like my other lens. Anything I can do about this or do I need to send to nikon?
