thanks Mako. I appreciate your help. In all pictures I focused on the area by the maroon bush by the building and thought I had focus lock. I will try again.

According to ViewNX2 and other EXIF viewers, focus was never locked in any of the pics. Check the AF/M switch on both lens and camera body. Cycle them to AF. Makes sure the lens is mounted properly, clicks in place, and the lens release button is not stuck...redo testing again. Good luck.

Mako, where do you see that focus was never locked in the viewers. I don't see that information when I look at the EXIF. Where do I look?

Simplest way..use viewNX2 and click on the "focus Point" box at the top right area so it turns yellow. If focus was locked and the green light was lit in the viewfinder at the time of capture...you will see a red box on the image showing what AF sensor was active. If no red box...no green light or lock.

Thanks. Yes, I have the red box.

That makes since. The re-size is causing that part of the EXIF to be dropped and why I can't confirm. Your red box confirms focus.

I retested and did get the green dot indicating focus was locked. I did as you suggested above and retested again at f8. The center is okay but the rest of the image is a mess still, especially on the left. I am getting rather frustrated.

Do you now get a red box in viewNX2 with the new pic? Have you tried with another lens? Do you get a red box with that lens? Me thinks there may be a lens contact issue. Defocus the lens so it is completely blurry (by turning the focus ring)...when you try to auto focus..does it move?

When looking at the RAW files in viewNX2, they all have the red box showing for the middle sensor, the one I thought I was using. This includes the RAW files of the jpegs I uploaded here. After defocusing the lens and trying to autofocus it does move.

Here is the latest test. f8 ISO 200, VR off, shutter 100. Jpeg but the RAW file showed the red box indicating focus was locked. Still the same issue.

It may be that the lens is out of calibration then. Set up a target like a flat newspaper on a wall. Something easy to focus on and flat to the sensor. The problem with using scenes like the one above is that the viewfinder focus system may not focus on what you think it is. 3D scenes can be a problem when testing focus. You need a large flat target like a brick wall. Use aperture priority and shoot wide open (smallest f number). Change ISO so that your faster than 1/200s shutter speed. Take a few shots (in good light if you can) then take a few using LiveView. Liveview will give perfect focus and if the Viewfinder shots are a bit blurry in comparison, then it's a lens calibration issue. That assumes all your other lens are OK.

Don't get frustrated, it takes a little time to sort it out.

Thanks Mako. I tried it but I don't see much difference between the two. Losing light now. I think I will have to send it in and try to get repair or new copy. I wish I would have used it more early on to know if there were issues right from the start. I don't do many landscapes and used my other lenses for portraits, closeups and telephoto nature stuff.

I doubt best buy will do anything. Will probably need to send it directly to nikon

actually, if under warranty, best buy will likely take it back, give you a new one and deal with the defective RMA. that is what you get for generally higher prices

Yes best buy will do that but i thought that was only during their return period. After that they typically make customers deal directly with manufacturers but worth a shot going to the store first.

The 18-55 kit lens is not worth using, IMO. It's just not sharp enough. You would be much better off with the Nikon 35mm f/1.8 prime for $200, and let your feet do the zooming.

Thanks BlueJakester. I have that lens and it is a great lens. Sometimes it is just not wide enough and no funds for high priced wide angle that I will not use often.

I am going to try Best Buy today. Otherwise will see about sending in to Nikon.

I can relate to the expense of lenses. Thus far I've been successful in having a 3 lens kit with my D5200. I have the Nikon 70-300 VR, 35 f/1.8 and a Sigma 10-20 wide angle. Surprisingly I use the Sigma much more than I had anticipated I would. The following two photos were taken with the Sigma and I'm very satisfied with the IQ for a $430 lens.

I added the vignetting to this image, that's not from the lens.

Update from today.

Since I didn't purchase the geek squad extra protection and it was purchased as a kit including camera and lens, Best Buy would only deal with it by sending all of it including the camera, lens, all the cables etc, etc, etc. I wasn't willing to send all of that since it seems to be only this lens and not the camera.

I asked a question of Nikon tech support  about what could be done about the issue, including a picture, and someone named Nicole J responded saying they recommend using a lower aperture and sent a link for landscape lenses. Geez, certainly no help there.

So I will be sending it in to Nikon repair and hope they address it. If not, I guess I will use the 35 for the little landscapes that I do until I can save for something for landscapes/walk about. I am considering refurbished nikon 18-105 or perhaps sigma 17-70. Money is tight right now so I am limited in what I can realistically afford.

I will wait to see what, if anything, Nikon does. I am doubtful that much will be done, but still hoping they can fix or replace, even if it is a refurbished one.

Your 18-55mm needs repair. It is quite a capable lens for its size, price and weight. There is not much of a difference between the 18-XX lenses as far as sharpness is concerned.

Here is a sample at f/9 on Nikon D5000 body.

Sharpening set to 1 in view nx. Color mode Dx1. No other processing.

Thanks vzlnc for validating that there is indeed something wrong. I will have it in the mail to Nikon tomorrow and see what they will do. I am hoping the warranty will cover.

Before you send it in, you really shout take some pics of a flat target (50x focal length away) at 1/200s and wide open aperture in good light. Use both Viewfinder and LiveView so you have comparison. Otherwise you will have no real ideal of what Nikon did or a good way to check their work and contest it if needed.

here are a few snapshots for you. Literally snapshots taken at the side of the road today. One is the 18-55, which gives you a comparison of the type of results I get with mine to compare with your version. The other is the 35mm f1.8G. Which is which? Hmmm.... You can decide if the 35mm blows out the 18-55 to the point that the 18-55 isn't even worth using.

edit:  just for the record, the only processing done to these was importing the RAW to LR4, click the box for lens correction, bump sharpening from 25 to 40, set noise reduction to 30.  Both photos got the same treatment, in other words, the 18-55 wasn't "helped" by adding contrast or sharpening or saturation, etc...

If the 18-55 is a lost cause, you can either try to sell it as-is on Craiglist or eBay, or take it to the shooting range and do experiments on how well it holds up to abuse

Exactly. The 18-55 is excellent. I have taken many sharp shots with it. The OP's lens is apparently defective.

Which is which? My guess is the first shot is the 35mm 1.8.

definitely better than my defective lens.

they are indeed very close...and I think it would serve my landscape shot needs...if I can get Nikon to repair or replace.
