I noticed an advertising supplement in the newspaper featuring Glazer's Camera's PhotoFest 2012 this weekend (June 8-9). They've got free seminars and demos all day Friday and Saturday including one entitled "Olympus Pen and OM-D User Tips" (presented by Olympus) and another called "Understanding the Benefits of Mirrorless Camera Photography" (presented by Panasonic). It says this is the third annual event, so I was wondering if any of you has attended this event previously. If so, did you get anything out of it? Are these types of seminars just glorified marketing pitches, or is there any substance? I may try to attend the PEN/OM-D seminar just because I'd like to see what the OM-D looks like and what it can do (since I've yet to find a shop that has it in stock). I'm not in the market for it, but I'm still curious, especially with all the hype it's getting in this forum.
