Len Thanks for your reply. I am in a quandry about the D5100 and getting something smaller, if not much lighter. I looked at an Oly EM-5 in a store and was impressed by it's compact size. With a 14-42mm lens, it weighs only a little less than the D5100 with a 18-55 VR lens, but it is much smaller. It could easily fit in a fanny pack or a small belt bag. If I chose a fixed focal length lens, there are some pancake lenses that are even smaller. The Oly seems sturdy (at least as good as a V1), and it supposedly has better moisture protection and a metal body. The sensor seems plenty good enough from reviews I have seem, but it is not as good as the larger one in the D5100. I am somewhat reluctant to buy into a new system, and there surely will be a learning curve with it. But I while find the D5100 to be less intuitive than I thought, I suppose I can get it soon enough. The D5100 isn't to be a repacememt for my D300 or D90, but a supplement for those times when I don't want to lug around the heavier bodies, but I just want to have a lighter camera for casual use. I want a camera that has a viewfinder and doen't have the annoying shutter lag and fussy menus of my P&S cameras. On the other hand the lenses I would usually take with my D300 or D90 are large and heavy (18-200VR, 16-85VR, or 70-300VR, putting on the 18-55 VR doesn't save enough weight), and some of the 4/3 lenses that have equivalent FOVs are lighter and more compact. Another consideration is cost. The Oly with a 14-42mm lens is near twice the price of the D5100 body alone. Maybe I should just return the D5100 and wait and see what becomes available later.
