70-300mm zoom
This is one of the longest lenses available and extends to 30cm so the zoom can go very far. It can capture scenes from far away in detail. However, the quality isn't at clear as other lenses due to this far-reaching zoom feature but it still produces a good quality image.
50mm
As a lense, this is the highest quality that you can get at up-close photos as the zoom feature doesn't hinder the focus of the camera. By no need to adjust for zoom, the overall quality improves and it produces high-quality portrait photos.
50-135mm zoom
Finally, this lens is the most common lens that comes with a camera. The zoom is average and the quality is as good as you can get with a basic camera lens. Also, it is very versatile and the features can be used in many ways to get the best picture you can.

Features of lenses
Aperture - Aperture is 'the opening in the lens.' When you hit the shutter release button of your camera a hole opens up that allows your cameras image sensor to catch a glimpse of the scene you're capturing. The aperture you set impacts the size of that hole. The larger the hole the more light that gets in - the smaller the hole the less light.
Zoom - When using zoom in photography it means to make the subject of a photograph appear closer than its actual distance (or subject distance) from the focal plane of a camera. Zooming is achieved either optically, using an arrangement of lenses to manipulate the light entering the camera, thus making the subject appear closer, or digitally by cropping an image to make the subject appear closer than it really is. In nearly all situations optical zoom is preferable to digital zoom as the latter will result in a reduction in the resolution of the image captured, and if used too heavily will cause an image to appear pixilated.
Focus - A lens is an optical device that consists of a curved material that allows light to pass through it. Depending on the design, a camera lens, either built into the camera or attached and interchangeable, consists of one or more elements that both diverge and converge light to focus it onto the photosensitive surface and re-assemble the light reflecting from the scene that has passed through the optics, resulting in an image.
