It takes in just a tad more than what a normal lens would.

But getting up close to the work with a normal lens may not be the best way to get good close-ups.

They have special vaulting so as not to be in contact with the normal lens.

Their angle of view is smaller than that of a normal lens.

The Topcor is reputed to be one of the best normal lenses ever made.

Cannon offers this normal lens featuring tilt and shift movements.

Bokeh is now a normal lens design parameter for very high quality lenses.

But unlike a normal lens, the artificial one is adjusted only for distance vision and cannot change shape to focus on nearby images.

The less specific use is to mean a lens that has a longer focal length than a normal lens.

Some cameras' "wide angle" lens also are constructed optically like normal lenses.

It will also increase the divergence of any wave which is incident on it in exactly the same way as a normal lens does.

Future studies should address the possible functions of HSPB2 in normal lens.

A camera with rising front lets a normal lens be raised to include the top of the building without tilting the camera.

The normal lens, because it often has a wide aperture, is often used for street and documentary photography.

Typical normal lenses for various film formats for photography are:

But then Roger Newton doesn't use normal lenses.

The term normal lens can also be used as a synonym for rectilinear lens.

The design appears in other applications where a simple fast normal lens is required ( 53 diagonal) such as in projectors.

The cheapest portrait lenses are normal lenses (50mm), used on a cropped sensor.

These taken together produce an "h-stop" designation which approximates the corresponding f-stop of a normal lens.
