Even though photography is an ART, besides knowing your DSLR camera (and, sometimes, besides knowing your compact one, or, even, your smartphone) you might need some technical know-how. This tutorial has no aim other than to help the beginners. For deeper learning, please consult the Internet.
LESSON 4: LENSES
Our first question when we are buying a lens is: fixed lens or zoom? Let’s see some differences between them.
Generally, good zooms are more expensive than fixed lenses.
A fixed lens is more reliable than a zoom as all its components are fixed.
Fixed lenses have better light abilities and, therefore, take better images.
Range of the angle of view
The range of a zoom is larger.
Size and weight
Zooms are bigger and heavier.
With a couple of zooms, you can have a wide range of focal lengths.
Contrarily to the zoom, with a fixed lens you must go backward or forward to modify your composition (sometimes, you must change the lens). How many you need? Zooms, a couple. Fixed lenses, minimum three (but you can have 2 zooms and one fixed lens…).
