Whoa, this new Olympus LS-100 Portable Audio recorder looks crazy. I believe it's a bit overkill for something like basic DSLR video work, but some people believe 'There's no such thing as Overkill'. Then again I don't really record Rock Concerts, so maybe something like this could come in handy for some shooters. BHPhotoVideo.com has this nice video review, and writes up a short article about the specs from the new Olympus LS-10 8-Track Portable Audio Recorder (found here). It certainly has a more modern look than the Zoom H4n. If it's something you find as a must have, it's already available for under $400 bucks (click here).
