<p>Consider a few things when you purchase a lens-</p>
<p>1. Bodies will come and go- wear out, become out-dated, etc. Lenses are a lifetime investment. Don't go cheap.</p>
<p>2. One lens won't do everything well. If anyone made an 11-300mm f2.8 lens, the image quality would likely suffer.</p>
<p>As I was accumulating my kit, I made a lot of mistakes- buying lenses because they were cheaper, all purpose, etc. Now that I have a closet full of gear, there are 2 lenses that I reach for all the time- 24-105 f4.0L, and the 70-200 f2.8ii. Both with IS. There are instances when I shoot field sports where I'd like something longer, there are times I will reach for the 85mm or 135mm primes for portraits, but If I could have only 2- those are the ones.</p>
<p>Good luck!</p>
