Read the General ComparisonGeneralThe Nikon D5100 and Nikon D90 are digital SLRs from successive generations: the D90 from 2008 and the D5100 from 2011. The D5100 is the lighter and smaller body. It weighs 560 g against 703 g for the D90, a 143 g difference, and measures 128 x 97 x 79 mm against 132 x 103 x 77 mm. That weight saving matters most for travel and walking days. | ||

Read the Optics ComparisonOpticsThe D5100 is the stronger choice for heavy cropping, with 16.2 megapixels against 12.3 on the D90. That gives more room to crop a distant bird or a group shot down to one face. Its standard ISO range runs wider too, 100 to 6400 against 200 to 3200. Both use the Nikon F DX mount, so the same F-mount lenses fit either body. The D90 answers with a pentaprism viewfinder rather than the D5100's pentamirror, and a 4.5 fps burst rate against 4 fps. Neither body stabilises the sensor, so handheld work in dim light depends on a stabilised lens. | ||

Read the Video ComparisonVideoThe D5100 is the clear pick for video on a modern screen. Its maximum video resolution is Full HD and its frame rate reaches 30 fps, against Standard HD and 24 fps on the D90. That gives sharper output and smoother motion, and the D5100 also offers built-in timelapse, which the D90 lacks. File handling differs too. The D5100 records MPEG-4, MOV and H.264, while the D90 records MOV only, giving more options when importing clips into editing software. | ||

Read the Features ComparisonFeaturesThe D5100's flip-out screen is the standout control difference, letting you frame accurately with the camera held overhead at a parade or low to the ground for flower shots. The D90's fixed screen forces you to work at eye level or guess the composition in those positions. The rest of the controls and connectivity is a close match. Both offer a 3-inch LCD with live view plus built-in and external flash support. Neither includes GPS, wireless connectivity, Bluetooth, weather sealing or a touch screen, so geotagging and remote transfer need add-ons on either body. | ||
Builtin flash ⓘA built-in flash will often be positioned right above the lens. This will automatically pop up when you activate it. |

Read the Storage & battery ComparisonStorage and BatteryThe D5100 supports SDXC cards alongside SD and SDHC, while the D90 stops at SDHC, so the D5100 accepts the larger-capacity cards useful for a full day of Raw shooting. Both have a single card slot and neither charges over USB. Battery ratings differ sharply under their stated test conditions: the D5100's EN-EL14 carries a 2200-shot rating against 850 shots for the D90's EN-EL3e. Both batteries are charged in an external charger rather than in the camera. | ||

Read: Verdict
Verdict
For most buyers the D5100 is the better choice. Its 16.2 megapixels give more cropping freedom, and its standard ISO range reaches 6400 rather than 3200 for dim indoor work. Full HD video plus a flip screen covers family clips and awkward-angle stills.
Choose the D90 if you prefer its pentaprism viewfinder, or for short action bursts where its 4.5 fps rate helps. Otherwise the D5100's resolution, ISO flexibility, Full HD video, articulating screen and SDXC support make it the stronger purchase.
