Ultimately, it is image quality that makes a camera worth buying. For an SLR, image quality greatly depends on the lens. While color, noise, exposure and dynamic-range are properties of a camera, distortion, vignetting and chromatic aberrations are properties of the lens. Sharpness and contrast depend on the weakest link. That is, the camera cannot capture more details than the lens lets through. Conversely, it is quite possible for a lens to transmit more details than the sensor can capture.
Note that the 24 megapixels sensor of the D3300 is very demanding and requires a lens with an great resolving power. This means one of Nikon’s premium lenses instead of a typical kit-lens which should be avoided at all costs. The image-gallery was taken with the 18-55mm and one can easily see how inconsistent the sharpness. Small apertures are required to get anything remotely acceptable. In order to show the resolving power of the D3300, indoor ISO crops were taken with a Nikkor AF-S 24mm F/1.4G EDNikkor AF-S 24mm F/1.4G ED.
Image-quality is quite good with a suitable lens. The lack of anti-alias filter means it can capture finer details than previous models, now on-par with Nikon’s mid-range DSLRs. Sharpness also stays more consistent as ISO sensitivity is raised when Noise-Reduction is disengaged.
Noise levels are surprisingly low until ISO 400 and barely noticeable at ISO 800. By ISO 1600, a hint of color noise starts appears but considering a whopping 24 megapixels of resolution, this is unlikely to be visible in most common print sizes. As usual, noise increases steadily at each additional stop. Still, ISO 3200 and 6400 are very usable for mid-size prints. The ISO 12800 setting is a stretch but remains usable for small 4×6 prints and web use. The newly added ISO 25600 level is one step too far though.
The multi-segment metering of this DSLR has been improved over its predecessor. It does not overexpose so severely but it still happens more than average. Small-to-medium bright areas are often clipped, turning down EC is necessary in scenes with a little bright sky or strong highlights. It now shows up to 1 EV of over-exposure under typical conditions.
There are 6 Picture Control styles, each can be modified in terms of sharpness, contrast, brightness, saturation and hue. The Neutral setting provides the most realistic rendition but some colors are noticeably off. A Hue of -1 and Contrast of -1 produces more natural results while rendering more details in shadow areas. The Standard setting is much more punchy yet colors are way too red. Both Landscape and Vivid modes show over-the-top-colors not suitable to represent reality.
Sharpness is controllable in 10 steps. The default of 2 is rather soft, particularly for a camera without an anti-alias filter. Pushing it to 4 improves things considerably with introducing visible sharpening artifacts. Although anything more shows halos along edges.
The white-balance system performs well. Preset and custom white-balance are very accurate. Automatic white-balance is good but not perfect. In broad daylight, there is not much to complain about but it sometimes leaves a cast under artificial light at night. Most times, the cast is gentle and color-temperature is rarely significantly off. Custom white-balance works just as intended though.
The Nikon D3300 is impressive when it comes to speed, compared to other entry-level offerings. This is one of the areas where Nikon improved the most since the D3200. Operations are nearly instant. Shutter-lag is instant, followed by a very brief blackout. This camera does not have a focus motor, so it relies on lenses to perform AF. This means that focus speed can be extremely variable. Particularly with the supplied kit-lens, the D3300 AF is sluggish by modern standards. Switch that for an AF-S 24mm F/1.4G and it becomes much more reasonable.
Performance of the D3300 is characterized by the following measurements:
Power On: Instant. Excellent.
Power-Off to First-Shot: 1s. Superb.
Autofocus: ½ – 1s. Heavily depends on the lens. Good to slow. Focus confirmation is instant though.
Shutter-Lag: Nearly instant. Good.
Blackout: Very short. Really good.
Shot-to-Shot: 2/3s. Average.
Video Recording: ¾s to start, instant to stop. Average. Too bad for the slow start.
Power Off: Just under 1s, very good.
As shown above, this DSLR performs quite well. Shot-to-shot speed is unimpressive, despite sustaining 5 FPS in continuous drive mode. The D3300 lacks a video mode again and the sensor is therefore unprepared. It takes almost 1 second after pressing the Video-Record button for the camera to start recording.
The Nikon D3300 is Shooting-Priority which lets it return instantly to Capture mode from Playback by touching the shutter-release. The only time it takes longer is when shooting in Live-View. From there, exiting Playback takes just a little more time.
This entry-level DSLR has good throughput to the memory card yet a small internal buffer. It manages to shoot 6 RAW files before slowing down, while it can take up to 100 JPEG images. This gives it a whopping 20 seconds of full-speed continuous drive.
The new sensor of the D3300 uses much less power than its predecessor’s. This one reaches 700 shots-per-charge according to the CIPA standard which is good for a compact DSLR. Without using the built-in flash, more photographs can be taken without changing batteries.
