1^st Post

I've had a 24-70 mm lens for a few years now, and obtained some stunning results with it on my D7000. Never thought I had an issue with the lens until I switched to a D800E.

On the D800E, I am really noticing some softening in the corners of the images, and to my eye this is more noticeable in the right side of the image than the other. The center of the images are always pretty much tack sharp, and the corner/edge softness is not really that noticeable until you zoom in at 100% on the images.

I am assuming that this was not noticed on the D7000 because those areas of the frame would have been cropped by the D7000's sensor.

The lens has already been sent back once to Nikon for cleaning and calibration..

My question is this. Is this fairly typical behavior for this lens? If I were to try different copies would I stand a chance of finding one that is sharp from corner to corner or is that something that is really just a golden unicorn when it comes to zooms?

G,
Have you read the Nikon technical tips on using the D800 series?
If not: get the PDF at any Nikon site.
After reading, consider the my opinion that any lens is a compromise, and probably none of them is perfect, alas.
Regards, Gilbert

Can't relay answer your question without the complete lens name eg. Nikon AF-S NIKKOR 24-70mm f/2.8G ED.
That lens goes for around 1600 $US and shouldn't be a problem. Older versions etc may not that good.

Also you are pixel peeping which is OK but with your camera "corner/edge softness is not really that noticeable until you zoom in at 100% on the images" is a thing to worry about if you are printing 40x60 inch prints and viewing them from a foot away;~).

You may want to check out DxO reviews for lenses that are recommended for your camera or byThom for a lot of info on all things Nikon. I purchased his book for my D600 and it was/is very helpful in setting up the camera and explaining how a setting effects the image etc, something the Nikon manual doesn't do very well.

Don't get any edge issues with my 24-70 on the D3. o.O

Maybe it's the camera, there were focus issues early in the launch with D800's, don't recall if the E series was also a problem.

I recall byThom having a discussion about this and a home test to see if there was an issue that required Nikon service.

Yes this was a problem with the Nikon D800 series so both versions were effected. It is fixed by a recalibration of the AF unit if I remember correctly.

thanks...camera was bought in decemeber of 2013 and already sent back to Nikon once to check for damage after a slight tumble...they did recalibrate it and replace the bayonet mount at that time..

it could just be that I am expecting things to be in focus that should not be?

I'll try posting some photos later to get feedback from the experts on this site.
