If you’ve ever lugged a super telephoto zoom lens around, you know how heavy and bulky it can be. That’s the beauty of the this lens – it’s just over 4 and a half inches long collapsed and weighs only 15 ounces. Compare that to a typical SLR camera lens with a comparable 600mm equivalent lens, which weighs more than twice as much as an Olympus OM-D E-M10 and 75-300 together! 

Strongly lit scenes where you are practically shooting into the sun are always a challenge, but this lens has a secret weapon that ensures excellent results, even under such unfavorable conditions: Olympus’s advanced ZERO lens coating. ZERO, which stands for Zuiko Extra-low Reflection Optical coating, enables the lens to deliver tack-sharp image quality while reducing ghosting and lens flare when shooting against bright light, and provides increased durability, lessening the chances of damage to the lens surface 

One of this lens’s most interesting features is the unique-to-Olympus Movie & Still Compatible mechanism, or MSC. This technology provides amazingly fast, and nearly silent autofocus operation. You’ll really notice the benefit when you play back your HD video and the only thing you hear is the ambient background noise in the scene you were filming; what you won’t hear is the sound of the lens moving as it focuses or changes aperture. This lens is perfect for tracking action.
