I am going on a trip shortly and I am bringing my Nikon v3 as backup to my Nikon d750. I was "fiddling" with my focus menu with the 10-100mm lens mounted. It has always, I felt, been a sharp lens but since the "fiddling" it seems to have gone to a softer focus. I think I must have altered something either in the camera or the interaction of the camera with this lens. This trip is taking me to Antarctica so I do not want to return with soft pictures. I am not sure if I am looking at and testing my photos more critically than before in anticipation of this trip and seeing what in fact was always there. Or if I made some sort of maladjustment.
If anyone has encountered a similar situation or has an advice, I would greatly appreciate it. Leaving on Tuesday.
Thank you

Kevin,
If in doubt, and you are out of time...rent a super lens for Antarctica. You will be glad you did.

Try fine tuning your lens. You can find a lot of information here. http://www.uglyhedgehog.com/search.jsp?q=fine+tuning+microadjustment&u=&s=0

Thanks for your input. I do have three varying lenses for the 750 and aa additional 70-300mm lens for the v3. The later lens seems unaffected on the v3. It is quite sharp still, so I suspect I might have adjusted the 10-100mm in some way and saved that setting. Although it is a mystery how. I will try the web site you recommend and refer back to my manual. If all else fails I will call Nikon on Monday.
Thanks

Well, if you messed with the settings why not using a simple 'reset'?????

It works wonders.

Very good idea. Dress warm.

I also vote for reset. It has magically made my cameras new again when I've found a way to program in totally incompatible settings.

Ok to start with reset but be aware reset doesn't reset everything. In particular I noted the other day in the manual that it does not reset exposure fine tuning on a D800. It may not reset lens fine tuning.

As always, read the fine manual (aka RTFM).

Whatever lens you use, take a look at these suggestions. I found this last night.
