The subject of what lens is best for travel is often an issue of weight, efficiency, and even price, but all these will have to take a backseat once performance comes in.
What do I mean by this? If you love what a lens does so much, you begin to ignore the fact that it weighs a ton, or that you had to take out a loan plus two months’ worth of salary to get it.
This is not to say, though, that lenses are the end-all and be-all of taking pictures, and taking pictures for travel in particular. They are not. What they do, however, is help us all get the job done as efficiently as possible, depending on our style of shooting and our needs for that particular moment. They are great tools, but remember that they are just that—tools that need someone’s skill to put them to use. That’s where YOU come in.
