Tamron's 70-200mm zoom lens lets you do lots of different things with your shots, and is extremely versatile. The beauty of a zoom lens is that you have a variety of focal lengths in one lens. What this means is that you can save on room when travelling and also save on weight when heading out for a long walk. Here are some situations where a zoom lens will be useful:
Wildlife photography - For good wildlife photos, it's often necessary to get up close and personal to your subject. As you often can't get close to your subject a longer focal length is needed. A zoom lens such as the Tamron 70-200mm lets you do this with ease, and is more than capable of shooting fast so that you don't miss that all important shot. Zoom lenses become particularly useful in zoos when you could be moving from photographing elephants some distance away to close-ups of smaller animals in pet's corner.
Macro work - Just because the lens is a zoom, doesn't mean it can't be used to capture some great macro shots. The zoom lets you get up close to creatures that might be out of your reach for a close-up shot, like dragonflies hovering over water, for example. Also, using accessories like an extension tube will help you to focus in on subjects that are a little further out.
Creative - Zoom lenses give you plenty of room for creativity, whether it be using blur for abstracts or creating a sense of movement. You can also use this type of lens for zoom burst photography, where the lens is smoothly zoomed out or in during the exposure.
Landscape shots - A zoom lens might not be your first thought when heading out for some landscape photography, but they give you the chance to shoot the popular wider landscape as well as shots with longer focal lengths that focus on one aspect of the landscape. As mentioned above, it also means you can head out with just one lens rather than a bag full of kit. If you're a Tamron 70-200mm lens owner you'll know that it has a completely internal mechanism, meaning the lens doesn't rotate. This makes it ideal for using filters with, something that's important for landscape photography, as it means your grad won't end up at a crazy angle once you're all zoomed in and ready to shoot.
