A place to politely discuss the tools, technique and culture of photography.

This is not a good place to simply share cool photos/videos or promote your own work and projects, but rather a place to discuss photography as an art and post things that would be of interest to other photographers.

How big of a difference is f/4 and f/2.8 (alien.top)

I want to photograph a few sporting events locally.

2.8 is obviously a lot more expensive, but is it worth it?

70-200 lens

It’s twice the light. Useful for shutter speed and focus sensitivity. Focus speed and accuracy depend based on lenses in question. If you are shooting in daylight an f/4 will be plenty. At a well lit big event f/4 is plenty. As things get dark, fast action, and you are closer in(requiring higher shutter speeds to stop action of players) that’s where the f/2.8 may be needed. With digital, high speed ISOs are so good, that it often makes sense for the enthusiast to jump from 3200 to 6400 rather than spend another $1000 on a lens. If you are making a living with it as a primary lens, just buy the fast glass.
