How to determine a fast camera lens?
April 5th, 2010 | by admin |What makes a camera lens fast for sports photography? How do you determine what number on lens that tell you the speed of the shutter?
Hey,
Lenses don’t tell you which shutter speed you can use. They tell you its maximum, widest, aperture. On prime lenses, you will see like f/1.8, while on zoom lenses, you will see f/4-5.6. It might also say 1:1.8 or 1:4-5.6.
The smaller then f/* number, the faster your shutter speed can be. The faster the shutter speed, the more you can freeze your object. For sports, I use lenses that are f/4 or wider. You need at least 1/500 to freeze a fast person, like a football player.

first of all I am no expert in sport photography.
the lower the apertur number will give you the faster lens.
a sport lens will be typicaly a zoom lens and they tend to have a higher number.
long lenses and small number are very expensive.
the shutter speed will depend on how much light goes in, the more light the faster the shutter speed.
the wider the aperture, the higher the shutter speed.
the side effect of a wide aperture lens will be the area in focus, it can be very shallow (wide aperture) or very big (small aperture).
hope that helps

It’s not speed per se. The larger the maximum aperture of a lens and when used at that maximum aperture, the more light is allowed to enter the camera, the faster the shutter speed can be set, the shorter time the picture can be taken, the faster the speed of the whole process.
The shutter is part of the dSLR camera, not the lens. On the lens, look out for the f/value. The lower that number, the faster the lens. Normal lenses can have maximum apertures as big as f/1.2. For telephoto lenses, those that are ideal for sports, grab immediately if the number is lower than f/3.5.
