The 82nd PMA (Photo Marketing Association) International Trade Show is underway, in Orlando, FL. This show is huge for the photography community, and lots of big announcements generally happen there.

PC Magazine sent Cameras Lead Analyst Terry Sullivan. Check out his slideshow for pictures of the delectable-looking, tentatively named Pentax 645 medium-format digital SLR camera (pictured at left), shown here for the first time in the U.S.; Sony's underwater cameras and accessories, soaking in aquariums; Olympus booth reps throwing cameras on the floor; and other interesting displays. He'll be adding more captioned photos every day, so check back.
