All around lens, good for travel and landscapes.  Suitable for group photos as well.

My choice for most wide landscape.  This lens is sharp and provides the option of shooting wide or moving a little closer a subject and isolating distracting elements in a scene.  It's also great for travel when you are in a tight area, like city streets and have limited space to shoot buildings and architecture.

A great landscape lens and medium to long zoom.  Sharp in the corners.

Nice portrait lens that is affordable and performs well with shallow depth of field and bokeh.

Low cost and good performing lens in a classic focal range.  Light weight and works well on a gimble.
