Following are some of the qualities of 18-55mm Kit Lens:
3. Macro: Since the minimum focus distance is very less (0.25 m) in this lens, it helps us to focus on objects just millimeters away from the lens. If used creatively, this enables us to get splendid macro shots without having to purchase a macro lens. I am not saying that 18-55mm lens can replace a macro lens, but it can serve the purpose in many scenarios. If mounted with a macro adaptor, the macro capability of this lens is further enhanced many fold times. The pics below illustrate this:
4. Sharp Picture Quality: Since the Kit lens has a small aperture (higher f-stop value), your picture will have a huge depth of field. This is a blessing for a beginner since the subject will not go out of focus as compared to the lenses with a large aperture which limits the depth of field to very low value thereby increasing the chance of blurring out the subject. Moreover, the Kit lens has image stabilization which acts as an icing on the cake.
5. Focal range: It is the special focal range (18mm to 55mm) of this Kit lens which covers almost all aspects of photography. Be it landscapes or be it portraits. This lens can do it all. The only place where it falls short is in nature (birds and animals) photography.
The final verdict is that 18-55mm Kit lens might not be as good a lens (technically) as many others in the market, but it will help you grow as a photographer. It is the restrictions this lens imposes on us which force us to grow creatively and become better a photographer and ultimately understanding the worth of an 18-55mm Kit lens, respecting it for what it is. It is like a dark horse which will win your heart in the end.
