This Canon 55-250mm IS II is one of Canon’s most popular lenses because it’s super sharp, focuses very close, has a perfect telephoto zoom range, has Image Stabilization for sharp hand-held photos in dim light, and is small, light and inexpensive. You can pay more to get a lens that works better while being rained-on or blasted in a sandstorm while being beaten around by a news photographer, or that works on expensive full-frame cameras, but even if you pay more for something like a 70-200mm f/4 L IS, you’ll have a bigger lens to carry around, it won’t be any sharper, and it won’t have as broad a zoom range! There are many reasons this 55-250 is among Canon’s best selling lenses. Canon calls this the Canon Zoom Lens EF-S 55-250mm f/4-5.6 IS II. EF: Electronic Focus. All modern Canon lenses focus with a motor in the lens. -S: Only works on newer, small (APS-C) DSLRs. IS: Image Stabilization, which means no tripod needed except at night. See Why IS Matters.
