What makes a photo really sharp? Anonymous
What makes a photograph sharp? Is it mostly the lens? And what causes so many pictures to be as unsharp as they are?

I must have been really lucky with my canon digital camera since most of my pictures turn quite sharp.
But when I browse the internet there are so many pictures that are really unsharp. Even in situations where it's important with sharp pictures. And some of those photographs are taken by pro/semi-pro photographers using cameras much more expensive than mine.

Often even small size pictures can be made really sharp and of good quality. But I see amazingly high numbers of very large size pictures that are unsharp and blurry, it's really confusing. The reason could of course be that there are many less experienced photographers on the internet. But why then does even my cheap camera take sharper pictures than most of what I see on the internet.

One exeption is magazines like national geography, their photographers always have really nice and sharp pictures.

I don't understand what your question is, at first I thought you meant to simply bring up a topic about DoF but this is clearly not the case. When viewing full-sized pictures through your internet browser, it is very likely that these will be, in a sense, blurry. However, this is the equivalent of holding a photo print an inch away from your eye. It is magnified. (Any photo would seem unsharp if magnified to an extreme degree.) If the same picture is resized to a reasonable scale, you will notice that it will usually become more sharp. Compare thumbnail vs. full sized picture even on 4chan when the photo is 1600x1200 or greater. Size of the photo and scope (resolution of the screen) is important when viewing a picture on the computer.

Another example can be illustrated with a digital camera's LCD. Sometimes when a picture is taken, it often looks clear on the LCD. However, a slight blur could not be noticed since the screen's resolution is so small. It only appears sharpt when it is not. Very slight movement of the subject or even shaky hands of the photographer can go unnoticed if only relying on the resized image on the camera's LCD.

Even cheap cameras will take pictures which have at least good focus somewhere in the picture, and if you use auto-focus the picture will often look good.

But if you look at pictures like the attached, it's very blurry and unfocused.
I was wondering why such pictures are so common?

Because people don't know how to use a camera.

Some photos are made unsharp with photoshop to give a warmer feeling like portraits, whereas others will have more sharpness like nature.

The better the lens, the sharper the picture. The less magnification, the better the picture. Working with single focal length lenses (non-zooms) and larger film sizes/higher res CCD's will always give you a better picture. Try comparing a zoom lens set at 50mms against a 50mm F1.4 lens, or a contact print from an 8x10 camera to an 8x10 enlargement from a 35mm transparency and you will immediately see the difference.
