Pentax K-x Competitors

As well as being compared against other entry-level DSLRs, the Pentax K-x is also often compared to mirrorless and pro DSLRs. The Pentax K-x's top rivals come from Pentax (such as the K-r and the K-5) and Nikon (such as the D3100 and the D5100)

Generally, some of the advantages of the Pentax K-x compared to other entry-level DSLR competitors include: it has slightly wider dynamic range (12.5 EV vs 11.5 EV), has better image stabilization (sensor shift vs none), records movies in 24p, has a marginally larger sensor (APS-C 23.6x15.8mm vs APS-C 22.3x14.9mm) and has in-camera HDR.

However, on average it is slightly more noisy at high ISO (811 ISO vs 1,162 ISO), records lower quality movies (720p @ 24fps vs 1080p @ 24fps), has a significantly smaller screen (2.7" vs 3.0"), has a significantly lower resolution screen (230k dots vs 920k dots) and takes slightly lower resolution photos (12.2 MP vs 16.1 MP).
