Typically a "fast" lens with a maximum aperture of f2.8 or better (1.8). But if you have time for a longer exposure or can accept the grain/noise of higher film speeds, the lens you have can do the job.
of course if you want to kibbitz there are the magical and mythical 1.0 lenses too

Does camera lenses have long or short focal points?
The short focal length of a camera lens is so that the image the lens forms is small and can be focused on a piece of light-sensitive film.
What does archetypal lens mean?
a type of literacy lens. pertains to connecting with Greek mythology. ex of other lenses. feminist , Marxist , historical.
What is the difference the type of lens used in camera and in human eye?
Aside from the obvious with respect to tissue versus glass, the camera lens is a compound lens made up from several lens elements each having different characteristics. Some of these elements converge light rays and some diverge them. Also, a lens element cannot precisely focus all the colors of light at the same point because they have different wave lengths. Thus lens design has to compensate for this as much as possible. Lens coatings must be employed to minimize diffraction, dispersion and glare. As for focus, the position of the elements relative to the film plane has to change with the change in distance from the subject. I am no eye expert, but I believe the eye lens is much simpler in that it is one bioconvex element. It focuses by changing shape through the affect of muscles acting upon it. Certain deficiencies such as astigmatism, are corrected with glasses or contact lenses. It also cannot precisely focus all light wavelengths. How we deal with that as humans is interesting reading, but is far too complicated and unrelated to deal with here.
Is a polarizing filter the same as a haze filter?
A haze filter, typically an 81A or 81B Wratten-type filter is used to cut down the amount of ultraviolet light entering the camera's optics. You can use this instead of a clear glass filter to protect the front element of your camera lens. There are two types of polarizing filters - linear and circular. Depending on your type of camera (film versus digital), you may need to use a circular polarizer to be able to see through the lens system. Polarizers cut down the amount of light entering the lens by acting like a set of Venetian blinds and letting light only come in as a single plane. There is more information on polarizing filters in the question In photography what does a polarizing filter do?
In photography what is a telephoto lens?
When being used in photography, a telephoto lens is used as a long focus lens. This means that the focal length of the lens is longer than the physical length. This type of lens is often used for photography of animals.
What type of lens structure is found in a light microscope?
convex lens
What type of lens does a light microscope use?
Concave
How does light refracts as it travels through a concave lens?
What type of image can a concave lens form
What happens when light travels through the lens of a telescope?
The light or image is focused at a different position relative to the real position of the emitting light. This is dependent on the type of lens.
A type of lens that magnifies an object?
convex converging apex... :P
Do Light Rays converge or diverge?
Light rays converge as well as diverge. it depends upon the type of lens or mirror you pass it through. A concave lens or a convex mirror diverges the light whereas a convex lens or a concave mirror converges the light rays!
To what type of microscope is magnifying hand lens most familiar?
the light microscope
Can biconcave lenses act as a convex lens?
yes but it has to be in contact with a special type of light
What type of lens can cause a beam of light to focus or come together?
Concave lenses
Who originally developed the Fresnel lens?
The Fresnel Lens was originally developed by French physicist Augustin-Jean Fresnel. It is a type of compact lens used to project light within a lighthouse.
What type of lens would be needed to correct myopia concave or convex?
It would be concave lens. This is because it diverges the light before it enters the eye.
What type of lens refracts and spreads out light?
All lenses refract. You are talking about a diverging lens, which is thinner near the centre than near the rim.
