Three Lenses Every Photographer Should Own
1. General Purpose
A 24-70 mm f/2.8 is a great all purpose lens. It’s fairly fast, giving you greater control of the depth of field.
2. Macro Lens
A great macro lens is at least 50mm f/2.8. It beautifully captures close up details and can also be used as a portrait lens as well.
Typically a telephoto lens should be in the range of 70-200mm with at least a f/4. It gives you a great distance to work with and a shallow depth of field to ensure your subjects are in focus.
