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
