Lens speed
The largest lens opening (smallest f number) at which a lens can be set. A fast lens transmits more light and has a larger opening than a slow lens. Determined by the maximum aperture of the lens in relation to its focal length.

Lens Speed Test
I was at a photo trade show a few years ago looking for "deals" on cameras and lenses. I was looking for equipment to test for my web site and auctioning them afterwards. I found a Tamron 200-400mm f-5.6 in great condition for $280.
Lens Speed
Lens Speed is a semi-technical designation that rates or compares a lens' maximum f/stop value; i.e. a fast lens might have a maximum f/stop of f/1.4, conversely a slow lens might have a maximum f/stop of f/4.5.

Lens Speed
Versatility and lens speed are closely related. Once you have a plan of what you want to photograph and understand under what conditions you'll be doing so, you can then pick a lens with the speed to match those conditions.
LENS SPEED - The widest aperture at which a lens can be set. A lens with a fast speed has a very wide maximum aperture, such as ƒ/1.4, for example, and transmits more light than a lens with a slow lens speed, such as ƒ/8.
Lens Speed - determined by the amount of light your lens lets into your camera (measured by maximum f-stops)

Lens speed indicates how bright the image in the viewfinder will be. Lenses with larger maximum apertures provide a brighter viewfinder image but are not necessarily sharper or better than slower lenses.

Lens Speed
The largest aperture(smallest F-stop) at which a lens can be set. Fast lenses transmit more light and have larger openings than slow lenses. Determined by the maximum aperture in relation to focal length.
Lens Speed
The largest lens opening, e.g. f2 not f16. A fast lens transmits more light and has a larger opening than a slow lens.

the largest lens opening (smallest f-number) possible for a specific lens. (A fast lens transmits more light by way of a larger opening than a slow lens).

Lens speed:
Refers to the maximum aperture of a lens. A lens with a wide aperture is called "fast". e.g. a f/1.4 lens, accepting more light than a "slow" lens, e.g. a f/5.6 lens.

Lens speed is also a critical factor. The faster the lens, the faster the shutter speed you can use, which as the lens grows longer, this becomes even more important. This will be covered in the freezing action section in more depth.

The commenter above me is correct to say that the lens speed does make a difference. I often recommend the very same lens (s)he is using.
Prime lenses always have a faster wide open lens speed then an equivalent zoom. Prime lenses usually produce very good image quality wide open and are excellent one stop down from their widest aperture.

Adjusting the aperture or lens speed of your camera helps you focus on your subject in different ways.
Maximum Aperture or Lens Speed
The "maximum aperture" of a lens is also called its "lens speed". Aperture and shutterspeed are interrelated via exposure.
In addition to focal length, consider the lens speed and its focusing distance. The lens speed is determined by the f-stop setting. A faster lens will be heavier and more expensive.
To keep the camera so small, something had to give, and that would be lens speed and an eye-level viewfinder (electronic or otherwise). I would only use full telephoto in bright daylight since the small f/5.
Choosing the right lens is not easy as you will have to compromise between focal range, lens speed, size and weight, and of course (for most of us), the important factor price.
Lens Shutter A shutter located near or inside the lens optical system. Lens shutters are used mainly in compact cameras and in lenses for large-format cameras. Lens Speed The maximum aperture of a lens. See Fast Lens.
