Different Lenses for several Subjects

By Amos Navarro


There's a dizzying range of choices with regards to selecting lenses for SLR cameras. From wide angle to telephoto, zoom to prime lenses, fish eye, fast lenses, wide aperture lenses, the options seems to be impossible. It isn't truly. Just what boils down to is asking yourself a simple question: What do I want to shoot?

If you are just beginning in photography, then chances are you continue to be experimenting and finding out the things you prefer to shoot. You might shoot a few family portraits one day and landscapes from your holidays the next. However, you might have decided straight away that you just love taking pictures of wildlife and also this is all you want to do. In either case, the lenses needed to get the best out of these subjects differ greatly.

To match an expansive landscape image to your viewfinder, you would require a wide angle lens. Nevertheless, trying to have a portrait using the same lens would cause a tiny little person and not much else in the frame unless you are right in that person's face and smelling their breath. When seeking to take a picture of a wild bear from 100 or more meters away is just impossible (and you really don't want to get any closer to a wild bear). In a perfect world you'd probably get 3 different lenses for every of these subjects. However in a perfect world you'd also be a millionaire and be able to afford them all. Therefore, the option to take should be to decide the type of photography you're interested in and choose your lenses consequently.

Length: Zoom compared to Prime

You will find benefits to using both zoom lenses and prime (fixed or non zoom) lenses. Similarly, zoom lenses are versatile, and minimize the need for a whole bag filled with lenses that you must change and change again when you're out shooting. However, a high quality prime lens could be gold. Prime lenses, if they are well built, generally create a crisper, higher quality image, mainly because they've got fewer pieces of glass and moveable parts.

The other advantage of prime lenses is usually that because of this, they have an inclination to generally be "faster" than zoom lenses. Basically, which means that you should use slower shutter speeds as being the lens requires much less light to create a correct exposure. This is particularly useful if you need to take portraits using available light.
