I got a new (used ebay) Nikon 18-140 lens a couple of weeks ago, have not had time to take many pictures till this weekend. The few I have taken in good light were good, I don't think the lens is defective. My granddaughter was here this weekend, she is 99% of my pictures at this time. I took some pictures late Friday afternoon around 6:30-7pm, like many times in the past. Now sunset is hitting around 7:15 in south Alabama now so there is less sun than 2 weeks ago. The pictures on Friday look good in the camera view (D5600). took a few Saturday under shade of trees, they looked good also on the camera. this morning I took around 7:30am, plenty of sun light. These were in front of a storage building with lap siding that I have been taking pictures since she was born. I put one of the sticker / circles that have like  1 Month on the same place each month to show her growth, after we ran out of the ones purchased at the store I make them to continue making a monthly picture story. We are on Month 28 today. I said all that to explain that the ones this morning were in the same place that I have taken many many pictures from the same distance of about 10-12 feet from her. the first 18 months were with a Cool Pix LX100 and since then I have been using the new D5600 with the lens that came with it 18-55. So all the pictures had look good on the camera. I wait until she is gone Sunday afternoon to load them to my computer and see what I really got. I was very disappointed when I saw what I had. Again I don't feel the lens is defective, a few I took Friday after noon I had set the camera to "Scene" and "Sunset" and they looked much better. And some I took Saturday that was still set and thy looked ok also. I don't like to use that setting as it gives the picture a false fake look to me, but it does handle the lack of light. I am sure with time I will learn the settings that predefined setting is using and fine tune to a better liking.

So both lens are f/3.5-5.6 and to my understanding that is telling me when the lens is zoomed all the way out to the max that 5.6 is the f stop. So if I have the 18-140 on the camera and go to 140 it will allow less light and that light may in fact be less at that distance that where I am actually at. Even if I am incorrect about that, my question comes in about the pictures I took this morning at the same place I have each month from the same distance. I may have zoomed up closer just playing / testing the new lens but it could not have been much as it is only about 10-12 feet. A couple this morning were much better because I had left the "scene" setting on from the day before and it was "sunset" but when I change to
"P" they all have the grainy / blur that is caused by lack of light. I always take in "P" so I can hold the button and get 2-4 pictures. It is my understanding that in the "P" Program I have the option to make adjustments but the camera will still adjust if I don't. and with the original 18-55 lens that has worked pretty well.

 

What is the difference that is causing this with the new 18-140?

Vibration and Focus are both set to A / Auto

I know you have put a long explanation in but it would be better with some images showing the problem and including the Exif details, i have a feeling the main problem could be the exposure modes you are using, they both make decisions to get you a correctly exposed image, perhaps though not the settings idealy suited to your needs.

Mike is correct.  Examples along with the EXIF data (aperture, shutter speed, ISO) are very important and necessary for us to assist with issues like this.  Any photo editing tool I have seen provides the EXIF information to you.

mikew and Tbonz, thanks for your quick reply. As I look back at my post, wow, I did say a lot to ask a simple question and if you knew how slow I type... After asking last night, on the way to work this morning I remember the pictures I took a couple of weeks ago late in the afternoon had the same poor quality and thinking, "glad my new lens has not come in or I would have thought it was bad" . So I may have changed something on my camera that is causing this. I will get some pictures with the details to post for more info.

Did not get the pictures uploaded but did try a reset on the camera. My understanding is there is 3 places to do the reset and none do a total reset. The only way to do that is take the camera apart and remove a battery, I am not willing to do that. Figured I would try the simple hold the Menu and Info button at the same time for x amount of time. That changed some things but I could see others stayed the same. This weekend I took some pictures and did some with different setting to compare to. I did most in the P mode that I normally use. Connect and copy to pc, all the pictures look good, no grainy look like the 2 weekends before. It may have been the Reset or maybe it was just poor light those times.

I think it is good for now, if happens again I will get pictures to this post since it already had the detailed info.

Thanks to everyone for you Help!
