They never actually existed....

\"Point and shoot...\" was only the first part of the sentence. The whole sentence really said: \"Point and shoot and get really crappy results which put you off taking pictures forever\".

The other ludicrous term was \'focus free\' as though that was a good thing!!!

This term was never applied to \'autofocus\' cameras which are great, but was used to describe crappy \'point and shoot\' cameras that were incapable of being focussed in the first place.

How the ad men changed a deficit into a supposed \'bonus is one of the greatest con tricks in history. It\'s a bit like a car being \'engine free\' or a job being \'salary free\':bouncy:

actually, it\'s one of those \"work-free\" jobs I\'ve been looking for... :D

I guess \"point and shoot\" only applies to guns now... :rolleyes:

@MT only use point & shoot with guns you are familiar with and are sure of your target. We like the term \"gun control\" that means hitting what you are aiming at.

@Avelorn, the f- numer has to do with the size of the iris opening behind the lens. The higher the number, then smaller the opening and the greater the depth of field. If you camera has a sweet spot for the f-number, it may be due to a defect in the lens or the iris or that the high f- stop is not being compensated by a longer shutter time. It may also be that with the high f- stop that the shutter times are too long for you to remain still with the camera - thus the need for a tripod. Hope this helps.

(I am not a professional photographer, and I do not play one on television.)

Yes.. I know :) I justed mixed the size and number up in my head. I don\'t think I have an aperature \"sweet spot\" on my camera.. I only have two aperature modes. 2.8 and 5.6.

\"The sharpness your lens is capable of achieving varies widely as the aperture size changes. If the aperture is too wide, the lens is most subject to loss of sharpness from lens aberrations. If the aperture is too narrow, sharpness will be lost due to light diffraction. Each lens has a \"sweet spot\": a middle point in the aperture size range where it is least affected by aberrations on the wide end and diffraction on the small end. This range varies by lens model, but is generally somewhere around f/5.6 and f/8. By placing your aperture within the f/5.6-8 range, you will have the potential for achieving sharpeness far beyond what is possible at such apertures as f/1.4 or f/32.\" (www.photo.net)

There is also optimal distance to the object where the lens focuses best.. etc.

EDIT*
I don\'t know if that\'s equally true with macro photography though, as spacemunkie said. But I\'m guessing, the cheaper camera, the more important it is.

However.. I think it\'s more or less confusing to discuss the higher ends of photography. So I leave it at that. I haven\'t observed the differences with my camera.. but I will no doubt experiment where it takes the sharpest pictures.. and leave the theory to someone who knows it. :)

All the best, Sven
