  Focus free lens - Wikipedia, the free encyclopedia
A focus free lens is a photographic lens whose focal point is fixed at its hyperfocal distance.
Rather than having a method of determining the correct focusing distance and setting the lens to that focal point, a focus free lens relies on depth of field to produce acceptably sharp images.
Focus free lenses are used in the lowest end and cheapest cameras; disposable and low-end point and shoot.

 Eyepiece - Wikipedia, the free encyclopedia
An eyepiece is a type of lens that is attached to a variety of optical devices such as telescopes and microscopes.
They vary in their internal lens configuration, and different designs are sometimes more appropriate both for different types of viewing, and for different types of telescope.
Magnification is calculated by dividing the focal length of the telescope objective (the main lens or mirror) by the focal length of the eyepiece.

 Focus - free-definition   (Site not responding. Last check: 2007-09-11)
The focus, or focal point of a lens or parabolic mirror is the point onto which collimated light parallel to the axis is focused.
The focus of a hyperbolic mirror is either of two points such that light from one is reflected as if it came from the other.
Instead, the focus is the point from which a formerly collimated beam appears to be emanating from, after it travels through the lens or reflects from the mirror.

 Kodak's shortsighted DC210
In most situations, a camera that's "focus free" (or equipped with a lens that's "focus free") is incapable of taking photographs that are in focus.
Photos are only in focus when they're of things at or near a single distance decided by the manufacturer, a distance you have to deduce for yourself by trial and error.
If you focus a lens -- or if an autofocus camera focuses its lens -- at a certain point, some of what's both in front of and behind that point may also be in focus.

 Focus Free Camera: Any with an "good" lens?
I realize "focus free" is more or less an advertising ploy to make a cheap, highly limiting design sound impressive, but nevertheless I am wondering if anyone has such a camera which they recommend.
Otherwise, "focus free" means a simple lens and a small aperture and there won't be a lot to chose between cameras.
When a lens does not have to be made to accomodate a bunch of variables of focus and apurture, it's not that hard to make reasonably good, IMO - sorta like an extrapolation of the primes vs zooms concept.

This allows the user to control the point of focus by looking at specific parts of the image; an onboard sensor follows eye movement and the lens automatically changes focus as the eye moves to points within the frame.
When the landscape mode is selected, the camera's focus is fixed at infinity to capture distant subjects in sharp focus, ideal when taking pictures through windows.

If you love a lens but it's not "supposed" to be good, believe the pictures before reputation, published test results, or the status of the brand.
Interestingly, the only lens I've ever used that got much in the way of compliments from non-photographer viewers was a 40mm f/2 Rokkor-M. Finally--this is again apposite to the foregoing point--most viewers can't tell.
Mushy feelings of delight at the optical prowess of this or that lens squelching up from within ourselves is something we photographers pursue for ourselves and for other photographers.
