Competitor classes

compared toTravel zoom competitors

Generally, some of the advantages of the Pentax S4 compared to travel zoom competitors include: it has a slightly wider aperture (f/2.6 vs f/3.2), is much smaller (ultra compact (83×52×20 mm) vs compact (97×61×33 mm)), is thinner (0.8" vs 1.3"), is significantly lighter (115 g vs 178 g) and has a viewfinder (tunnel vs none).

However, on average it has a much narrower wide angle lens (35 mm vs 28 mm), has a much smaller screen (1.6" vs 2.7"), doesn't have image stabilization (none vs sensor shift), takes slightly lower resolution photos (4 MP vs 9.6 MP) and much lower maximum light sensitivity (200 ISO vs 6,400 ISO).
