Is there a good replacement for Breezebrowser? They do not seem to update frequently enough to support the new camera systems (D300s). I mostly use Breezebrowser for my first view of the images, checking focus, and renumbering; never for conversions.
BBPro is dependent on Nikon/Canon (and others) releasing an SDK for the new cameras. Often the manufacturers aren't real fast at doing that. Chris Breeze is pretty good about getting a new version out within a couple of weeks of the SDK being released.
If it is just for use as a browser, why not just use Nikon ViewNX. It is all I use and have no need for anything else. Plus it is free and updates fairly frequently.
As far as I can tell the most recent SDK available from Canon is from May 2009 so that would mean no. It is interesting too that in that release, they dropped support for all consumer models starting with the 10D and earlier.
