While nipping at the heels of its top level sibling, the D7000, this baby has a couple of advantages: a smaller size and arguably a less challenging user interface. It is in fact an excellent prosumer or enthusiast camera.
In the hand it’s a practical camera and, at a pinch, could be used single-handed, with the shutter button, mode dial and command wheel within mills of the forefinger and thumb. But you wouldn’t, would you …!
The review camera was supplied with the f3.5/18-55mm kit lens.
Nikon D5100 Features
The CMOS sensor has 16.2 megapixels and uses the Nikon DX format, which gives a 1.5x factor when compared to a 35 SLR.
The 7.5cm LCD screen is articulated in a horizontal sweep, can swing through an arc up to 90 degrees clockwise and up to 180 degrees counter-clockwise: I found this to be a big help when the D5100 was tripod-mounted. Its resolution is a high 921,000 pixels. Optical viewing is via a pentamirror.
Maximum image size is 4928×3264 pixels, from which you can make a 42x28cm print.
Video is at the top level of Full HD 1920×1080 at 24/25/30fps which can be captured with auto exposure and full auto focus but requiring you to press the shutter button half way to trigger the focus action.
As the lens handles the focusing chore I guess the performance is directly related the quality of the optic; the kit lens worked satisfactorily in my tests.
The onboard mic of course captures all the bumps and squeaks as AF does its tricks. And they are considerable. Plug in an external mike!
It is also advisable to use memory cards rated as class 6 or higher to avoid hiccups when recording.
If you try to shoot stills while recording a movie the latter action stops but you can later retrieve individual video frames as JPEGs.
ISO ratings run from ISO 100 to 6400 but you can lift this to ISO 25,600 by lifting the sensor gain. If you want to squeeze some extra lumens out of a tricky shot there is an HDR function that uses two exposures to maximise the capture of shadow and highlight details. This is selectable from the camera menu and presents some interesting options to the educated user: you can select an exposure differential between the images of up to three f stops. The function allows some smoothing of the paired images; this I presume is to better match the images if they are shot handheld … but serious HDR practitioners would obviously use a tripod! And HDR only works with JPEG images.
The special effects mode is a blast! Applicable to stills and movies, there is night vision, color sketch, mini effect, silhouette and more. How about night vision, captured at an ISO equivalent of up to ISO 102,400 — complete with tonnes of wild pixels! The great thing is that each has an enormous range of adjustment. Let’s wait for an answer from Olympus with its Art Filters … this one sure beats the pants off the latter!
It was only when the ISO setting reached 6400 that noise became noticeable, but not objectionably so.
This one is for the educated user; it would frustrate the beginner. Having said that, the D5100 is an aspirational camera: it will give legs to the ambitious photographer and give wings to ambitions to capture advanced imagery.
Quality: excellent, full bodied colour, razor sharpness. Top performer.
Why you would buy it: excellent articulated LCD screen; you want Full HD with auto focus shooting;
Why you wouldn’t: there is no dedicated ISO button.
A couple of points: I was not happy with the Live View button and the movie record buttons placed on the top surface near the mode dial. A very cluttered area with a total of nine controls in the vicinity.
