Many people ask me a lot about how to obtain clear images in digital photography. Generally, I would respond that the lenses have a role to play in this. If you have invested in a good lens, it is more than likely that you will have clear photos. This applies to all sorts of venues including weddings, etc.

When I provide my opinion about an SLR camera being better than a ‘point and shoot’ camera its not because the large SLR looks the part of a professional. The SLR is better because of the range of control it gives a photographer. ‘Point and shoots’ typically do all the adjustments for you; hence the name ‘point and shoot’. You do nothing in the way of adjust the camera settings before taking a picture. An SLR, however, gives you more flexibility in controlling things such as exposure and shutter speeds. Having this much of control can help you achieve just the result you’re looking for. Coupled with a good lens, taking great pictures is only a few adjustments and a click away. Lets first understand what a lens does.
Fixed length lenses usually refer to lenses having a fixed focal length. This means that they focus only at one particular length and is typically equivalent to your average wide angle lens. The only way to make a subject appear bigger is to physically walk closer to the subject. The lens offers no flexibility to stand in one place and zoom in closer to a subject. When comparing a fixed length lens to a zoom lens, the differences are apparent. A fixed length lens is smaller and will have a larger maximum aperture. This large aperture is ideally suited for low light photography, such as indoor photography. Fixed length lenses offer clearer pictures than zoom lenses.
We discussed fixed length lenses along with zoom lenses above. What is a zoom lens? Its a lens that offers a few different focal lengths. The zoom lens is used to ‘fill the frame’ of a photograph by ‘zooming in’. This zooming in feature is excellent when you have difficulty in physically getting closer to your subject.
Different types of zoom lenses exist. By far, the best zoom lens is one that offers an optical zoom. The other type is a digital zoom. Pictures taken using digital zoom often have artifacts or ‘noise’ visible. This is because the final image is a cropped, larger version of the photo you take. It is not an accurate representation.
One other significant issue with zoom lenses is the fact that the more you zoom, the more dimly lit the subject will appear. This is because the lenses have much lower apertures and are not the most ideally suited for low-light photography.
On some rare occasions, you may be able to solve this problem by using a flash. However, since a flash is only effective a few meters away, heavily zoomed in subjects will not benefit from flash photography at all. Again, a popular question is ‘What lens should I buy’ and the answer largely depends on what you’re trying to achieve. If you’re just starting out, then it is better to get a lens with a better range of focal lengths.
As you grow more experienced, you will know what lens to pick for the job. Or if you don’t want to ‘beat around the bush’, there’s a quicker way to learn more affective techniques with Amy’s digital photography success guide.
