A normal lens is one which produces images corresponding to the normal viewing span of a human eye. Generally this focal length is taken as 35-50mm. So, photos taken at focal lengths beyond the range are termed to be wide or telephoto and hence the wide and telephoto lenses.
The 18-55 mm kit lens, despite popular disregard, is one the most versatile lenses out there and can be used for shooting landscapes to portraits with ease and still produce quite amazing results.
The photos above have been shot at 18mm and 55mm respectively from almost similar viewpoints.
Comparing the results against dedicated lenses for the same is not a fair game though. The dedicated lens, such as a 35mm or a 50mm F1.8/1.4 are meant to be high performance and have immense light gathering power, but they lack the versatility of a zoom.
The photo of Laxmi here shows why it is worth investing in a prime lens, despite whatever limitations it may have.
All said and done, a normal lens is not fit for shooting landscape while I would go about shooting portraits on a normal lens all day long happily! Tell me what do you think about the judgments in the comments.
