Chapter 3D: Zoom Lenses

Zoom lenses are most of the time worse than Prime lenses in terms of image quality. The really good ones are very expensive. On top of that, most of them will change variable aperture setting depending on the focal length. That's not good for filmmaking, unless you want a particular effect. For example, most kit lenses (the lens that will come with most consumer DSLR cameras) are 18-55mm F3.5-5.6. What this aperture setting means is that at its widest (18mm) the lens will have a maximum aperture of F3.5, and at its longest focal distance (55mm) it will have a maximum aperture of F5.6. In other words, the image will become darker the more you zoom in. The lenses I will be suggesting for you in this article, won't have variable aperture, which is great for filmmaking.

So, are they any good?

They are great in what they do best, change the focal length gradually. Slowly zooming in a shot can create a sense of intimacy with our objective. Check out this example from Stanley Kubrick's "The Shinning":

A fast zoom can give the audience a sense of surprise and shock. Check out this example from Quentin Tarantino's "Django Unchained":

Lens Suggestions

Legacy lenses (fancy word to say old) offer incredible bang for the buck! Most of them will have fixed aperture, which is great. Now I will share with you some of the cheapest zoom lenses that you can find online:
