Ενα ενδιαφερον αρθρο για την αναγκαιοτητα ή μη της χρησιμοποιησης τριποδου γραμμενο απο τον Ken Rockwell με τον γνωστο απολαυστικο τροπο.
Εχω περασει σχεδον ολα τα κομματια του αρθρου εκτος απο καποιοες αναφορες του (ενδιαφερουσες) σε προηγουμενες δεκαετιες.

Many people still cling to the mystique of the tripod, even though tripods went out with film cameras.
Hang onto your tripod if you're shooting a real camera like a Hasselblad, Gandolfi, Linhof, Silvestri, Horseman, Tachihara, Gilde, Seitz, Sinar or even a Wisner, Wista or Mamiya, but toss it if you're shooting a popular digital SLR. Also hang on to your pod if you don't have IS or VR on your telephoto yet, and for very long time exposures.
Tripods are no longer required, and actually often degrade sharpness, because shutter speeds have climbed and IS and VR lenses reduced the need for slower speeds. The new factors which have buried the tripod over just the past couple of years are:
1.) IS and VR lenses eliminate blur caused by camera motion.
2.) Smaller-than-35mm-format sensors use shorter lenses, which have plenty of depth of field at larger apertures.
3.) Diffraction becomes more significant with smaller format sensors, making smaller apertures like f/16 off limits because diffraction makes images visibly softer with today's high-resolution cameras. Compact point-and-shoot cameras have much smaller sensors, and have no apertures smaller than f/8 for exactly this reason.
4.) Better lenses which are sharp wide open. We used to need to stop down a couple of stops for optimum sharpness.
5.) Today's digital SLRs' have spectacular quality at high ISOs, if you're in marginal light. Shoot at ISO 400, 800 and 1,600 on a DSLR and the results are as good as slow film used to be.
Sadly many people still look like idiots using tripods with digital cameras in daylight. These guys are throwbacks to the 1950s, or the early 2000s.
Most people associate tripods with professional photography because they were required for the first two centuries of photography. High school photo teachers have been scaring students with "use a tripod or your photos will be fuzzy" stories for decades. This was the case before digital.
I took a class from Susan Coppock in San Diego in the 1980s. She taught us that any time you set up a tripod in a national park, every tourist is going to stop and take pictures right next to you, even if you're in the middle of nowhere. They see a tripod and presume you are a professional photographer, and must therefore have discovered the one and only best place from which to make a picture.
If you love your tripod then don't let me poop in your ice cream; but if you're carrying it around to use with your Canon or Nikon DSLR because someone else told you it made sharper pictures, think again. I make more and better pictures when I'm not weighed down.

If you're shooting a digital SLR, forget the tripod. The tripod only gets in the way and encourages the misuse of smaller apertures which soften images.
Don't shoot at smaller than f/8 or f/11 unless you really need it. Unlike with film, digital sensors in 2007 have such high resolution that we easily can see the veiling effects of diffraction.
Half the time that someone sends me a soft image they can't figure out, it's because they were blindly shooting at f/22 on a tripod. f/22 in digital softens the image exactly like squinting your eyes.
I hated having to haul around a tripod and its crippling effects on letting me setup where I want.
Don't be a turkey: leave your tripod in your trunk until after dark. Only pull it out for moonscapes.
If the light is marginal, shoot several frames and pick the sharp one later. I shoot indoors and at night all the time without a tripod, and get more dynamic images because I'm free to move around and experiment.
Still Think Tripods Make Sharper Images?
Try it yourself. Make a shot from your 'pod at f/22. Then pick up your tool in your own bare hands and make some shots at f/8 or wider. Look for yourself. It's obvious.

*difraction :Diffraction is a loss of sharpness or resolution caused by photographing with small f/stops. The same softening effect happens when photographing through diffusion cloth or window screens.
