I am a novice photographer and have not the money nor the time to research and purchase multiple lenses. This lens really is an all in one outdoor lens. I love the zoom feature and have found that it can capture with great clarity things at a long distance. It is durable, easy to attach to the camera base, fairly lightweight and versatile. While it is an expensive lens it is cheaper than its Nikon and Canon comparables and was rated better than both brands by photography gurus that know more than me. I have been very happy with this lens except have found that its aperature is not wide enough for good low light indoor pictures. It does fine if there is enough light or if you are using a flash, but if you prefer natural lighting and are looking to take most of your pictures in an indoor setting I would suggest going with a lens that provides for larger aperatures (a 50mm or a 35mm to be exact) But, if you love landscape photography or have busy kids that love to be outside than this lens will fill most of your needs and will be worth the money.
