Pentax k 5 vs pentax k 7?
The K-5 is the newer of the two. It has a 16.3-megapixel APS-C sensor and came out in 2010, while the K-7 has 14.6 megapixels and dates from 2009. Both use the Pentax K mount, both have in-body stabilisation, and both take the same lenses, so your choice comes down to the body itself. My site doesn't list prices or other differences, so check those elsewhere.
Either body suits an everyday kit. For general use, the Pentax HD DA 16-85mm f/3.5-5.6 ED DC WR is a sensible all-rounder. For portraits, the Pentax HD D FA* 85mm f/1.4 ED SDM AW gives lovely background blur. For wide scenes, try the Pentax HD DA 15mm f/4 ED AL Limited.
See the full Pentax K-5 and Pentax K-7 pages for the complete lens lists.
