Digital Home Thoughts: Panasonic LUMIX G VARIO 100-300mm F4.0-5.6 MEGA OIS Reviewed by PhotographyBLOG

"The Panasonic LUMIX G VARIO 100-300mm F4.0-5.6 MEGA O.I.S. is a new telephoto lens for the Micro Four Thirds system. With MTF bodies having a crop factor of 2x, it provides an effective focal range of 200-600mm in 35mm terms, yet only weighs just over 500g."

Need a little more reach for your Micro Four Thirds camera? The Panasonic 100-300/4-5.6 is it. I prefer it to the Olympus 75-300/4.8-6.7 for the price (US$550 vs US$900) and the extra half a stop at the long end. It might be a bit larger, but at these sizes I doubt they will make much a difference; the length and weight also means I recommend this for use with a Panasonic G or GH camera for the grip and viewfinder.
