I was playing with it just the other day. I was impressed by how far it it goes with just a few turns.  Lightweight, compact and might in reach the new Lumix 45-200 F4.0-5.6 Micro 4/3rds zoom lens from Panasonic is a beauty.  With its 90-400, 35mm standard equivalent focal length it really gets out there. When coupled with the Lumix G1 Panasonic Digital camera system the speed of focus is amazing, and since stabilization is built into the Panasonic digital SLR camera system, there is no extra charge for clear clean shake reduced images. This lens is a must have foe your Panasonic DMC-G1 and DMC-GH1 camera platforms, where else are you going to get a 400mm equivalent lens with stabilization and F5.6 gathering?

Remember that the micro 4/3rds system works with the recently announced Olympus micro 4/3rds camera and offers an adapter for the regular 4/3rds cameras so you can use this lens on the entire Olympus Digital Camera platform too.  Also remember that Roberts has the best prices on digital camera SD cards in Indianapolis, so stock up on Sandisk or Kingston SDHC cards while you are here.
