This is part VI of a series of what glass you will need. Each part will discuss a certain lens type and its applications.
Tele zooms cover the range 70/5omm+. Candid shots, sports, wildlife are typical applications (adding a close-up lens makes most of them as well capable macros).
Almost all tele zooms are actually too short for wildlife. You need at minimum 300mm here + some feature like AF lock are handy.
It is fair to categorize in three groups
- Consumer tele
- Pro tele
- Long tele
