J.D. Power and Associates have published their 2012 Digital Single-Lens Reflex Camera Online Buyer Report. Responses were collected via PowerReviews - a social commerce network recently acquired by Bazaarvoice - and reflect the attitudes of actual DSLR camera owners who used an e-commerce site to make their purchase. According to the report, Pentax ranks highest in online buyer satisfaction with a score of 899 (on a 1,000-point scale), followed closely by Nikon (891) and Canon (888). The average price paid for a digital SLR camera has increased from $937 in 2011 to $1,291 in 2012, reflecting a shift towards more prosumer-oriented and semi-professional cameras.
