Nikon D5100 vs D90: Which DSLR Wins in 2024?
Nikon D5100 and Nikon D90 are both crop-sensor DSLRs from 2011 and 2008, mixing up their names and specs is common because both are 12 MP bodies that accept F-mount glass and feel similar in hand.
Buyers confuse them because the D5100’s newer Expeed 2 chip and flip screen sound like upgrades, yet the D90’s twin control wheels and top LCD feel “more pro,” so newcomers assume the older model is better.
Key Differences
D5100 brings 1080p30 video, a 921k-dot swivel screen, and 4 fps burst; D90 offers 720p24, fixed 3″ screen, 4.5 fps, and an in-body AF motor for older lenses. D5100 wins ISO range (100–6400 vs 200–3200), while D90 has a larger pentaprism viewfinder and a top-panel status LCD.
Which One Should You Choose?
Need video, light weight, and a flip screen? Grab the D5100. Shoot stills with older D lenses and want direct dials? The D90 feels sturdier and cheaper used. In 2024, expect $150–$200 for either, so pick by lens collection and handling, not megapixels.
Examples and Daily Life
Vloggers mount the D5100 on a GorillaPod and flip the screen for selfie framing. Street shooters keep a 35 mm f/2 on the D90, ignoring video and using the top LCD to check settings without chimping. Both still deliver Instagram-worthy JPEGs straight out of camera.
Can I use my AF-D lenses on both bodies?
D90 autofocuses them natively; D5100 needs AF-S glass, so manual focus or adapter rings are required.
Which battery lasts longer for travel?
D90 uses the EN-EL3e (850 shots); D5100 uses the smaller EN-EL14 (660 shots). Pack two spares either way.
