It’s enough to mention here the Nikkor 18-200 mm VR or the Sigma 18-200 mm f/3.5-6.3 DC OS which, in the 18-55 mm range, fared definitely better than any 18-55 mm kit devices, still performing decently at longer focal lengths.
The OS system uses two sensors inside the lens to detect vertical and horizontal movement of the camera. It works by moving an optical image stabilizing lens group, to effectively compensate for camera shake. The lens design incorporates an inner focusing system, which prevents the front of the lens from rotating, thereby making it particularly suitable for use with circular polarizing filters and petal shaped lens hoods.
The Sigma 18-200mm f/3.5-6.3 DC OS (Optical Stabilizer) HSM Lens offers an "all-in-one" super-zoom lens solution, from wide-angle to long telephoto. DC lenses are exclusively designed for digital SLR cameras. The image circle (rear of lens) is sized to match the smaller dimensions used for the image sensor on digital cameras, It accepts smaller filters (62 mm vs. 72 mm) and can focus 7 cm closer.
