Nikon D5100 Review
Image Quality
All of the sample images in this Review were taken using the 16.2 megapixel JPEG setting, which gives an average image size of around 6Mb.
The Nikon D5100 produced images of outstanding quality during the review period. The D5100 produces noise-free JPEG images at ISO 100-1600, with ISO 3200 also looking pretty good. ISO 6400 only shows a little noise, while the fastest settings of ISO 12800 and 25600 are quite a lot noisier and suffer from softening of fine detail and a loss of saturation, but the images are still perfectly usable for small prints and resizing for web use. The images were a little soft straight out of the D5100 at the default sharpening setting and ideally require some further sharpening in an application like Adobe Photoshop, or you can change the in-camera setting for JPEG files. The night photograph was excellent, with the maximum shutter speed of 30 seconds and bulb mode allowing you to capture plenty of light. Red-eye was not a common occurrence with the built-in flash, and when we did encounter it, it was very moderate and easily cured by setting the flash to red-eye reduction mode. Active D-lighting managed to squeeze most of the dynamic range captured by the sensor into the JPEGs the camera produced.
Noise
There are 9 ISO settings available on the Nikon D5100 and the ISO speed can be adjusted in 1/3 EV increments. Here are some 100% crops which show the noise levels for each ISO setting, with JPEG on the left and RAW on the right.
The Nikon D5100 also has ISO Sensitivity Auto Control, activated from the shooting menu. If set to On, the camera will automatically adjust the sensitivity if proper exposure cannot be achieved at the value chosen by the photographer. The user can put a limit on the maximum sensitivity selectable by the camera.

Sharpening
Here are two 100% crops which have been Saved as Web - Quality 50 in Photoshop. The right-hand image has had some sharpening applied in Photoshop. The out-of-the camera images are a soft at the default sharpening setting and benefit from some further sharpening in a program like Adobe Photoshop. You can also change the in-camera sharpening level to suit your tastes by changing the Picture Styles.

Flash
The pop-up flash on the D5100 has several settings including Auto, Fill-in flash, Red-eye Reduction, SlowSync, Red-eye Reduction with Slow Sync, Rear-curtain Sync and Off. The mode of operation can be TTL, Auto or Manual, and there is Flash Exposure Compensation (FEC) available as well. Note however that unlike the D90, the D5100 cannot control wirelessly slaved system flashes. These snaps of a white ceiling were taken at a distance of 1.5m using the kit zoom.

Night
The Nikon D5100 lets you dial in shutter speeds of up to 30 seconds and has a Bulb mode as well for exposure times of practically any length, which is very good news if you are seriously interested in night photography. There is an optional long-exposure noise reduction function that can be activated to filter out any hot pixels that may appear when extremely slow shutter speeds are used. Do note that this works by way of dark frame subtraction, which effectively doubles the exposure time. The shot below was taken using a shutter speed of 10 seconds, aperture of f/11 at the ISO 100 sensitivity setting. We've included a 100% crop for you to see what the quality is like.

Image Stabilisation
The Nikon D5100 does not offer body-integral image stabilisation, but the kit lens bundled with the camera features Vibration Reduction, Nikon's proprietary lens-based optical stabilisation system. This allows you to take sharp hand-held photos at slower shutter speeds than with lenses that lack this function. To illustrate this, I took two photos at both ends of the zoom, with VR turned on and off. At a shutter speed of 1/3 second - which is very slow for this focal length - the photo taken with VR was still commendably sharp, but the one without VR was decidedly blurred, as the 100% crops below clearly show.

Conclusion
The Nikon D5100 successfully bridges the gap between the beginner-friendly approach of the D3100 and the more complex D7000, with the latter's fantastic 16 megapixel sensor being the icing on the proverbial cake. The D5100 does have a few minor handling issues, most notably the positioning of the Live View switch and the secondary controls on the rear, and it could also be seen as being neither simple enough for complete beginners or feature-rich enough for more experienced users. All in all, though, the D5100 delivers excellent still and moving pictures with the minimum of fuss in a lightweight package and is a serious rival to the Canon EOS 600D and the Sony A55.
In addition to the excellent image sensor, the free-angle, tilting and folding LCD screen is the real highlight of the D5100, opening up lots of creative possibilities for both stills and video. Full 1080p HD footage is another fantastic feature on what is a relatively cheap DSLR, although full-time auto-focusing in Live View mode is still a painfully slow experience and not well-suited to fast-moving subjects. The new Effects modes can be used to add a creative flair to your images, although the inability to manually control the camera's key settings means that applying the effect during image playback is often the better route to take.
Tellingly, our biggest gripe about the D5100 isn't a very serious one, in that the illogical positioning of some of its controls, especially the Live View switch and the separate Movie Record button, probably won't stop the camera's target audience from enjoying it. The lack of a dedicated ISO button will definitely irk some users though, only being accessible via the reprogrammable Fn button, something that the previous D5000 suffered from and which should really have been fixed by now.
Ultimately the Nikon D5100 easily overcomes its few real weak points, offering a compelling mix of great image and movie quality, precise and quick auto-focusing, accurate metering and a fantastic LCD screen, all in a format that most users will find intutive and enjoyable to use. This is precisely what a DSLR that's competitively priced for the mass-market should deliver, and judged on that criteria, the Nikon D5100 is a very worthy winner of our Highly Recommended award.

Review Roundup
Reviews of the Nikon D5100 from around the web.
whatdigitalcamera.com »
The Nikon D5100 updates the D5000 model, but continues to sit alongside the D90 in the range - quashing rumours that this latter model was to be replaced. The D5100 straddles the beginner and mid-level consumer market, merging entry-level 'fun' features such as Effects modes along with an image sensor pulled directly from the D7000 and many other features adopted from the D3100. Can the D5100 successfully fit snugly into the gap between those two cameras? The What Digital Camera Nikon D5100 review takes a look...

The Nikon D5100 is a newly designed camera improving on the Full HD video of the D5000 and introducing a new horizontally swivelling 3inch screen, and a new more compact body, that is 10% smaller than the D5000. It also introduces a new "creative effects" mode with 6/7 new filters, as well as a built in "merge to HDR" function, much like the feature you may have used on a computer to merge two (or more) different exposures to create a "High Dynamic Range" photo.

The arrival of the D5100 appears to signal the completion of Nikons refresh of its non-pro DSLR lineup. Its feature set and pricing mean that it sits very comfortably between the beginner-friendly D3100 and the high-end D7000 - it's clearly aimed to attract the attention of enthusiast photographers without cannibalizing sales of is sister models. A camera maker can judge the success of its market positioning by seeing how many people are wondering 'which model is right for me?' on discussion forums - and we think a D3100/D5100/D7000 progression would minimize such doubts. The official line is that the D90 maintains its position in the range, but both its naming and overlap with other models suggest that its role is now more one of historical interest than future significance.
