Image Quality

All of the sample images in this review were taken using the 20.9 megapixel Fine JPEG setting, which gives an average image size of around 13Mb.

Directly from the Nikon D7500, colours displayed in JPEG images are bright and satisfyingly saturated. Detail is also extremely well resolved at low ISOs, something which you can see by examining at 100%. When shooting at higher ISOs, you can see some examples of image smoothing from around ISO 6400 at normal printing sizes, or ISO 3200 if examining very closely. The overall impression of detail remains useable at A4 or below up to around ISO 12800, with the highest native settings of 25600 and 51200 best avoided unless you’re really struggling.

Like other cameras in Nikon’s range, the D7500 has expansion settings which can take up up to ISO 1,640,000. It’s fair to say that at this point, image quality is very degraded, and it’s possibly only those who intend to use the camera for surveillance purposes that would be interested in using these speeds.

When it comes to noise, JPEG images are impressively noise-free up to high ISOs of around ISO 6400. At the highest native settings of 25600 and 51200, there is noise visible even at normal printing sizes, so you’ll likely only want to use these settings at very small sizes. By examining corresponding raw files we can see that Nikon is applying a good degree of image smoothing to its JPEG files. While the resulting effect is generally natural and pleasing at low to mid-range ISOs, if you have photographed something particularly detailed you may want to apply your own noise reduction settings to get a better (or different) balance between detail and noise.

The all-purpose metering system is prone to slightly underexposing in some conditions, so you may find you need to bump up the exposure compensation to get a better balanced exposure. You can also activate D-Lighting in the camera’s main menu, which helps to bring out more details in shadows.

Automatic white balance copes pretty well with a range of different lighting conditions, but it errs ever so slightly towards warmer tones when shooting under artificial lights. That’s not to say the look is unpleasant, but if you’re after ultimate accuracy you might want to switch to a more appropriate white balance setting.

Noise

There are 15 ISO settings available on the Nikon D7500 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 D7500 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.

Flash

The pop-up flash on the D7500 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. These pictures of a white wall were taken at a distance of 1.5m.

Night

The Nikon D7500 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 30 seconds at ISO 100.
