There are no second chances in wedding photography. Admittedly the formal shots can be retaken or rearranged but even then every wedding is run to a strict schedule so if you miss a valuable moment or two whilst messing around with lenses etc, it's gone forever... and you know exactly what shot the bride and groom are going to ask for in their album, don't you?

After this paragraph we could add.

"To be on the safe side do consider using 2 cameras, one fitted with a medium telephoto lens and the other with a wider angle lens.
This combination will allow you to cope with any situation without having to cope with rushed lens changes and loosing the opportunity of a once in a lifetime shot."
