What's the name / specification for a camera lens which gives fast shutter speed in low light conditions? - shutter speed low light
I know that the larger the aperture, the faster the shutter speed, but it is a technical term used for the purposes of this type? I want one that can be used in low light conditions are, but do not know exactly what to ask.
It is a tripod or a remote trigger, already!

Shutter Speed Low Light What's The Name / Specification For A Camera Lens Which Gives Fast Shutter Speed In Low Light Conditions?

Just looking for a goal of "fast".
This would be an opening with af/1.2 or f/1.4.
The f/1.2 is the fastest.
Of course there are spectacles called "ultra-fast", with openings as large as the fastest f/1.0...about, "" goal, which you can get.
The word "fast" in this context, not necessarily connected to the shutter speed, but the ability of the lens to capture light fast (fast) because of the large aperture (aperture), allowing more light on the film in a "fast" to a lower rate or slow opening, for example, the lens with an aperture of only f/2.0
In addition, some say that applies to the designation of "fast", the shutter speed, you can shutter speed as fast as possible because of the fact that you are able to unlock "the more general goal so that more light into the camera.
If you have a goal, and openness is more openness, f/2.8...this say would be considered a relatively "slow & quot; Lens (one with af/1/2 openness).
You can always tell how "fast" in search of a lens in front of the lens (on the rim of the glass itself) and should read the opening is wider lens on the target, for example, f/1.2, etc..
If you took a photo shop, approached the counter, and
She said the seller is looking for a lens of "fast" for Nikon (for example), knowing that he can see exactly the type of lens.

For more information:
The type of lens you describe could be one of the telescopic type (such as a 400 mm used) to take pictures over long distances.
A lens speed can be regarded as an objective "ordinary" of the camera and still be fast, because all the F / stop.
Although the glass or can even with a larger diameter on the capture of light, enabling faster. This should not be confused with a wide angle lens (28 mm or 35 mm, for example), which are far larger than the area of the lens (50mm or 58mm, for example)
For example, here is a picture of a fast F1.4 lens for Nikon:

(Note where it says: f/1.4 on the aperture ring)
The goal you (mini-telescope ASTRO) ...
is probably this:

which is classified as "super-telephoto" lens.
So if you can take in search of a lens, the pictures in low light, is not necessarily large and bulky, you are describing.
