A telephoto zoom lens is a beat of a beast, and that’s because it possesses a lot of power in terms of zooming in on a subject, but when would you need this type of lens. It’s certainly not the type you’ll use for studio portrait photography, but it could well be useful for wildlife photography, weddings, events and landscape photography.

If you’re the type of photographer who loves the documentary approach, then this leans could be ideal. You can then take photos from a distance, without disturbing the atmosphere, and it means you can come away with more natural shots.

You will notice that these lenses can cost a considerable sum, and you should take your time before you make any decision. It’s not the type of lens that you can hold back on either, yet they don’t tend to lose value over time.
