No, it doesn't. My camera is a tool and it does what I tell it to do. Your camera should do what you tell it to do too.
You need to provide your camera with the proper tools to get it to do what you need it to do for you.
The two things that will provide you with a sharper image are:
1. A tripod, preferably, a good tripod.
This is the most under rated piece of photography equipment there is. The single biggest difference between a "snapshot" and a "photograph" is the use of a tripod. You can lean on a tree, hold your breath, or glue the camera to your forehead, but none of this will improve your steadiness and the sharpness of your image like a tripod will. The rule of thumb is (please, no comments about the origins of "the rule of thumb") that your shutter speed should be at least equal to, if not faster than the focal length of your lens. If you are using a 100mm lens, then your shutter speed should be at least 1/125th of a second. If you are using a 200mm lens, then 1/250th of a second is the slowest acceptable shutter speed to hand hold your camera. Even at these speeds, a tripod will improve your image sharpness. A tripod will always improve your image sharpness, and there are circumstances where getting any kind of shot will be impossible without one.
"But I don't like lugging around a tripod."
So don't. Just understand that your images are not as sharp as they could be if you did, so don't be surprised when your shots are not as sharp as they could be, and you see sharper images elsewhere. Refusing to use a tripod is crippling your photo taking ability.
2. Good glass (lenses)
Imagine spending $1000 on a stereo system for your car or your home and hooking up $49 speakers to it. What's it going to sound like? It's going to sound like a $49 stereo system. Cheap speakers create cheap sound.
It's the same with cameras. Cheap lenses (including the cheap zoom "kit" lenses that come with most DSLR's) produce images with less sharpness, detail, and contrast, than their more expensive brethren.
Prime (fixed focal length) lenses have been the route to go, offering much better optics and apertures than the cheap zooms, but now, there are some very nice zoom lenses available that will give you excellent quality as well. There are too many options and systems available to make any specific recommendations, but do your homework. There is a reason why the Nikon 70-300 f4.5-5.6 can be had for $109 and the Nikon 18-200 3.5-5.6 ED IF AF-S DX VR is $679 and the Nikon 70-200 2.8 AF-S VR ED IF is $1,600. All lenses are not created equal.
I understand that everyone is not financially able to spend $1600 on a lens, but there are always many levels in between. There are a couple of very good third party lens manufacturers (Tamron and Sigma) that can also be options.
