Summary: Overall, I had a very positive experience with the Nikon D5100. The camera is capable of delivering excellent results both for digital stills and video. As can be seen from image comparisons against other older Nikon DSLRs, the sensor on the Nikon D5100 and D7000 DSLRs is truly remarkable.
Conclusion: The Nikon D5100 is a solid entry-level DSLR camera that assumes some knowledge of photography from its users. Its image quality is on par with that of cameras boasting higher resolutions. It also has expanded bracketing of shots, usually found on pricier models.
Pros: Terrific image quality, even in low light, Compact and lightweight, Swiveling LCD screen
Cons: Sluggish autofocus in Live View and Movie mode
Summary: The Nikon D5100 is an important step forward in the history of SLR cameras. Make available, in an entry-level price, features and qualities typical of more expensive models and semi-professional. Just think of the 16 mega pixel sensor and, above all, the high quality in the images it captures.
Pros: Image quality, features and specifications semiprofessional.
Cons: We would have preferred a greater customization of the buttons.
Excerpt: The new Nikon D5100 D-SLR is a compact and lightweight DX-format camera. The body is about two-thirds the size of a D300, recording on SD/SDHC/SDXC memory cards. The similarly compact kit lens, an 18-55mm VR, provides good balance, and, along with my Nikon SB-900 Speedlight, all fits neatly into a...
Conclusion: The Nikon D5100 is a digital SLR that offers plenty to satisfy the needs of buyers looking to get a big sensor interchangeable lens camera for a relatively affordable price (under a thousand bucks/Euros).
Pros: Excellent image quality with low noise and good image traits (sharpness could be improved using good lenses), Small size for an SLR with good ergonomics, Flexible rotating 3 inch high resolution LCD with very good legibility, Great (Above average) battery life, Excellent performance, great burst ...
Cons: Kit lenses produce photos on the soft side (Solution: get better lenses if you want better sharpness), Limited movie mode functions: No manual exposure control, no wind filter, slow AF, Poor autofocus performance in live view mode, Camera is a tad too reliant on menus (needs more function-assigne...
Summary: Conceptually, the Nikon D5100 absolutely fills up the gap in Nikon's line-up between the entry-level D3100 and the much more enthusiast-orientated D7000 - getting married to the ease-of-use of the former with the picture great company's latter.
Conclusion: The D5100 appears to be another strong addition to Nikon’s consumer DSLRs. It maintains the small size and light weight similar to the earlier D40, D60, D3000, D3100 and D5000, but its electronics are updated to a DX-format sensor that is the best among current Nikon DSLRs and a high-resolution LCD...
Summary: With a £780 launch price, the D5100’s basic kit lens option is pitched squarely at taking on the Canon EOS 600D . The two models are very similar in specification, with particular focus on each of the vari-angle screens and 1080p HD movie modes.
Pros: Good image quality, improved live view mode, responsive AF, impressive movie options
Cons: Non-customiseable Effects, no AF-point lock, no remote commander, no DoF preview
Conclusion: If you’re in the market for a new DSLR you can hardly wrong with the Nikon D5100. It takes solid photos and videos, offering the response shutterbugs demand as they move from point-and-shoots to “real” cameras. We weren’t too thrilled with the kit lens, however.
