Ok so I am going to be buying myself a new Canon Rebel T2i in the near future, I am looking at a few options of lens.
i will get the standard 18-55mm lens it comes with
what i am confused about .. is the telephoto zoom lens
there are alot of different 70-200mm lens that are different prices, and i have no idea what the differences are.
Canon - EF 70-200mm f/4L IS USM Telephoto Zoom Lens
Canon - EF 70-200mm f/2.8 USM Telephoto Zoom Lens
Canon - 70-300mm f/4-5.6 IS USM Telephoto Zoom Lens
Canon - 70-200mm f/4L USM Telephoto Zoom Lens
i believe the T2i supports EF lens .. but really what is the difference ?
I dont understand the f/4L or the f/2.8 means ?
Any help i would appreciate it
