I am looking to start a wedding photography business and would like to understand what the best length is for the lenses.
Weddings and Events in general are the time when zoom lenses shine. The Zoom is important because you want to be out of the way for the most part. The two lenses to have are 24-70 and 70-200 will cover your entire range. If you can afford it you don't want the kit grade but the pro grade. The kit grade is usually something like 3.5-5.6 meaning it will only get a 3.5 aperture at its widest focal length. A pro grade will have a constant aperture and usually larger (smaller number). Even a constant f4 is better than a variable aperture because when you're zooming in and out you can still lock in the f4 and just let the shutter speed change. An f2 of course is even better than an f4 for a few reasons all based on its ability to let in more light.
- More light means faster autofocus which is good when shooting events.
- More light means more depth of field options which allows a focal point to really separate from other elements.
- More light means you can do indoor weddings easier and on a lower ISO
