I am interested in getting a zoom lens for wildlife photography but unsure about what focal length would be ideal? I currently have a 55-250 mm f4.5-5.5 and iddon't feel as though I don't have enough zoom to capture the birds etc. On top of that trying to capture the split second movements of animals would you expect to need a f2.8 or faster or slower?
Any assistsnce would be much appreciated
