Ricoh (parent company of Pentax), just released a free downloadable plug-in that lets shooters who use the popular Pentax 645Z Medium-format camera tether directly into Lightroom (so, this post either made you jump for joy, or shrug your shoulders).
Here’s the link to download the plug-in (for Mac OS and Windows). Scroll down in the list a bit until you see the plug download (shown above).
Here’s a link to their press release with more details than you probably care about.
Hope that helps (well, it helped somebody). 🙂
