Hi, I've had my new D5100 a couple of weeks now and I'm testing it out. Previously I owned a D3100 and had spectacular results. I knew my way around the camera and its settings, however all the shots I have taken with the D5100 with 18-55mm and 55-200mm lens have been really disappointing. Sometimes when out shooting I will get random blurred shots even though camera says all in focus, and many of the shots when viewed back on the PC lack focus and sharpness. Do you think it's possible I have a duff camera ? Any other ideas if I am doing something very wrong?

Can the blurring be fixed in Photoshop Elements 10? If so, please let me know how to fix.
Well, time to take more pictures! Thanks again.
I initially thought it was me as this is my first DSLR, until I took some shots with my trusted 8 Megapixel Panasonic Lumix DMC-FX55 Camera and noticed I was getting sharper pictures compared to the D5100 which is 18 Megapixels.
While researching the internet, I did everything you could do to rule out user error (ensuring camera mode was on auto, taking pictures on a tripod, using a delayed timer to rule out user shake).
I was also advised it might be a lens issue. The camera came with the standard kit lens 15-55mm, which I said was unacceptable as I'd paid over £400 for it, and was getting better pictures from a point and shoot camera which cost less than a third.
I finally persuaded the vendor (CURRYS) the camera was not fit for my purpose, and arranged an appointment to take the camera back to a store where there was a camera expert to inspect the camera.
I showed him the sample shots I'd taken, which apart from the pixel variation, showed the FX55 consistently produced sharper pictures.
He took a few shots and agreed he would have expected sharper pictures from such a DSLR. He also took picture on another D5100 he had on display, and it also produced the same blurry shots. He then took pictures on the Canon entry level 1100D, 600D and 650D, and the difference in sharpness compared to the Nikon D5100 was impressive.
He admitted he was shocked as he had over 30 years experience in using and selling cameras and would not have expected such a difference between the Nikon D5100, and the Canon 1100D (which he classified as an entry level DSLR), or the Canon 600D which he classified as being the equivalent of the Nikon D5100.
He agreed the camera was faulty, but was not sure if it was a batch issue as the one in store also produced blurry shots, or a QA issue, but they offered me an exchange so I paid the extra and went for the Canon 650D, which I'm very impressed with.
I'm posting this entry as it may help other people in a similar situation. I now have nothing but praise for CUURYS after nearly resigning myself to the fact that I may have to sell the camera and return to the latest model of my trusted FX55.
You have to use a minimum shutter speed which is equal to the focal length. For example, for 100mm focal length the shutter speed is a minimum of 1/100. On 145mm the shutter speed is a minimum of 1/145. On the D5100, which is an APS-C sized camera, you have to count with 1.5 multiplication factor. It means when you are on the focal length of 100mm it is equal to 150mm (100x1.5), so you have to use a minimum shutter speed of 1/150.
Or on 200mm focal length the minimum shutter speed is 1/300 (200x1.5=300). This will most likely guarantee sharp images if you shoot handheld.
The longer the focal length the more the camera will be sensitive to handshake. When you use your 55-200mm, you really have to pay attention to the shutter speed. To set desired shutter speeds, you have to raise the ISO when it is necessary. A tripod is also recommended.
Try the Shutter priority mode (S on mode dial) and see if my advice can help.
Happy shooting!
Edit: I see szlaszlo07 already touched on this in his excellent reply, my apologies.
Also, for those long range shots, watch your breathing. Take the shot on your natural pause (right after you exhale and right before you inhale). Let the air out, pause, shoot and breath back in. Just other ways to reduce movement in critical shots requiring you to be still.
Can you tell I traded my long rifles for lenses? :)

Note: The photos of the creek were done on a tripod.
As for VR, it needs to be disabled when you have the camera mounted to a tripod. Hope that helps and happy shooting! :)
As far as honing in on that single point focus, what focus settings would you suggest (focus mode, area mode)? Do you normally use the viewfinder or the display monitor to compose the shot?
For controlling depth of field, shoot in Aperture priority and go with an aperture above f/8 for landscapes.
I normally use the viewfinder, focus is a bit quicker than when using 'Live View' mode.
Happy shooting!
Aperture is what controls the depth of field (area in focus). Higher f-numbers will lengthen the depth of field so that more of the scene is in focus. However it has it's limitations, especially when you have a prominent foreground...in your case it's the weeds in front of the creek.
When you need everything from the foreground to the background to be in razor sharp focus, pro landscape photographers use a technique where by taking two shots (on a tripod) of the same scene.
The first shot is focused on the foreground elements and the second shot is focused on the background. You then blend the two images together in photoshop so that you're using the sharpest parts of both images.
If that sounds like too much work for you, then make sure your landscape shots don't include subjects directly in front of you, within say 10 feet of where you're standing.
Also, if you're using a tripod then I would make sure that VR is turned off, the ISO is set to 100 and you're utilizing the self-timer to keep your hands off the camera during the shot.
Hope that all makes sense and happy shooting! :)
