Let's see, "an equivalent range of 27-270mm," just what does that mean? Well, imagine you're on a whirlwind tour of San Francisco. At the wide end of the range, you can fit almost all of your fancy hotel room in the picture, or take a shot of the Golden Gate bridge and Alcatraz together. The middle ranges will snag you that perfect portrait of your spouse enjoying the antics of the lazy seals on Pier 39, and at full zoom you can get a close-up of the seal ringleader — or a cool, compressed-perspective shot of the cable car coming over the top of the hill.
Now you know why, if you can only pack one lens, this 10-100mm f/4-5.6 lens is the perfect choice to document your travels, because it has the versatility to bring home every opportunity with clarity and impact. Vibration reduction helps even your long-zoom shots to be captured without the motion blur that results from shaky hands. And meticulously designed optical elements keep all your shots sharp and free of color fringing.
