Popular Photography, in my opinion, is nothing more than one giant advertisement. I bought it a few years back, not knowing any better, and their equipment reviews look like they were written by the product manufacturer. In fact, some lines in the review looked like they were taken directly out of the product brochure!
I have been a subscriber to Outdoor Photographer for a few years, but I'm letting that subscription lapse. It's a good magazine with some EXCELLENT photos in it, but I can get faster, better, more accurate and (when it comes to product reviews) less biased information on the net.
