Choosing lenses can be confusing with so many things to take into consideration… Focal length, maximum aperture, weight, price, prime vs. zoom, etc. I’m going to try and break things down as best I can and hopefully give you a better understanding of all this so you can make a more informed decision on what to purchase.

What Do All Those Numbers Mean?
When looking at lenses, you’re going to see lots of different numbers. The first ones are going to be followed by mm. So, 24-70mm or 70-200mm or 16-35mm or whatever. This is the focal length. The smaller the number, the “wider” the lens, so these are called wide angle lenses. The bigger the number, the “longer” the lens, and these are called telephoto lenses once they’re 70mm or more. After these numbers, you’ll see some that start with f/. So, f/2.8, f/4, f/3.5-5.6, etc. This is the maximum f-stop or aperture (the terms are relatively interchangeable). The lower the number, the “faster” the lens, aka glass. The bigger the number, the “slower” the lens/glass. Let’s dig into these two sets of numbers a little deeper…
