As well as being compared against other entry-level DSLRs, the Nikon D3100 is also often compared to mirrorless, pro DSLRs, waterproofs, travel zooms and super zooms. The Nikon D3100's top rivals come from Nikon (such as the D3200 and the D3300) and Canon (such as the EOS M100 and the EOS Rebel T5)

compared toEntry-level DSLR competitors

Generally, some of the advantages of the Nikon D3100 compared to other entry-level DSLR competitors include: it records higher quality movies (1080p @ 24fps vs 720p @ 24fps), has much less startup delay (400 ms vs 500 ms), can focus continuously while recording movies, is slightly smaller (prosumer size (124×97×74 mm) vs prosumer size (127×97×79 mm)) and is thinner (2.9" vs 3.1").
