With the D750, Nikon has consistently refined the concept of a semi-professional SLR camera with full-format sensor and brought it to the latest technology: compared to the Nikon D700 (test) of 2008, the camera is about 200 g lighter, with 24 megapixels twice the nominal resolution and Presents itself as a modern game partner in the digitally networked world with a built-in WLAN module.
Flash features
Compared to the Nikon D610 (test), the handgrip has been lengthened slightly for a reduced housing depth, which means a considerably improved haptics and ergonomics. The main focus of this application is on the camera's extensive flash functions, settings for optimizing the picture quality and the Nikon D750 live AF (test).
Flash light storage
In terms of flash technology, Nikon has always been one of the leading manufacturers, with both the functionality and the high reliability of the fill-in flash.
Integrated flash unit
The user-friendliness is also convincing: With the wheel at the front of the shutter release, the strobe light can be adjusted over a range from +1 to -3 EV while the flashing button is pressed. You can choose whether a general exposure compensation should only affect the background brightness or the flash fading (individual function e4).
Master control
For line exposures you have the choice: If only the main exposure is to be varied, only the flash or flash and main exposure in combination (individual function e6)?
Another way to correct the flashlight is flash light storage. You must first assign this function to a key (individual function f2-f4). Let's say you want to shoot a portrait against a dark background: you take the face into the center of the image and press the flash memory button - a flashing light is triggered, and an L ("lock") with flash symbol appears in the viewfinder. You can place the portrait outside the center of the image and flash with the stored values.
Multiple recordings are also possible because the values remain stored until you press the store button again, flip the flash, or turn the camera off. All of the above features refer to the built-in flash as well as a plug-in flash system.
The individual function "Integrated flash unit" (e3), on the other hand, only refers to the flash-out flash unit. You can use this in i-TTL mode for fill-in flash, in manual mode (power adjustable between 1/1 to 1/128), in stroboscope mode or as a master for wireless control of an external system flash.
If the SB-500, SB-400 or SB-300 flashes on the camera, the display changes to "External flash", with only the TTL and Manual options available (SB- Control). However, the SB-700 or SB-910 will remain the same, as they can be used to switch between different modes.
In the "master control", the built-in flash can control external system flash units into two groups by pre-flashes. For the groups, select the TTL mode in the normal case, TTL or the off mode (-) for the built-in flash. In the latter case, the flash unit will only emit headlights that can be seen in close-up pictures.
When activated, a flash correction can be set for the built-in flash unit in the range of +/- 3 EV steps. The same applies to flash groups A and B. If you want, you can operate the built-in flash like the external system flash units but also in manual mode.
The D750 Multi-CAM 3500 II Phase AF Module has 51 measurement fields, 15 of which are cross-sensors. It is possible to choose between the three AF modes AF-S (single-frame), AF-C (continuous) and AF-A (automatic switching to AF-C when an initially static subject moves) : Press the AF function button on the MF / AF switch on the front of the housing to switch to the rear dial.
If you rotate instead on the front dial, the AF range control can be varied. For AF-S, the selection is limited to automatic field measurement, single-field AF and group of measuring fields (5 points)
Autofocus settings
The 5-point measuring field grouping is a good alternative to the single-field measurement, the latter should be used primarily when one wants to measure a specific point - such as the eye with a portrait-closeup. All five fields are equally authorized for field grouping.
This is different for the dynamic measuring field control with 9, 21 or 51 measuring fields, which is only available with AF-C and AF-A. Here you can select the starting field of the measurement in the viewfinder using directional buttons. When tracking the camera, the AF system will focus on the selected main focus area and use the adjacent AF fields if the targeted object leaves the selected focus field at short notice.
5-point measuring field grouping
The adjacent fields for dynamic measurement can be selectively hidden or displayed (individual function a4). If you select the 3D tracking mode in the AF-C / AF-A modes, the camera tracks the targeted object and, if necessary, focuses on other AF fields, and you can track the fields in the viewfinder .
With manual measuring field selection you have the choice between 51 and 11 measuring fields (individual function a7). This applies to the individual field measurement as well as the dynamic variant with 9, 21 or 51 AF fields. It initially contradicts the fact that the number of measurement fields is limited to 11, in order to have 21 or 51 fields available. In fact, this setting is not actually the effective, but the directional buttons selectable fields in the viewfinder.
If you have set 11 fields, you have to press the directional key only four times to get from the left edge of the AF area to the right, while if it is set to 51 fields, it will be ten times.

The 11-point setting thus allows a faster selection of the AF field, the 51-point variant a more precise one. Another basic setting is the shutter priority, which can be set separately for AF-C (Individual function a1) and AF-S (Custom function a2).
If you are photographing JPEGs or RAW + JPEG in composite mode, you should be well aware of the image quality settings.
Point 1: the image styles ("Configure Picture Control" in the shooting menu). Seven presets are available: Standard, Neutral, Brilliant, Monochrome, Portrait, Landscape and Balanced. Recommendation: "standard" or the slightly softer "neutral".
Brilliant "often looks too bizarre," well-balanced ", rather fuzzy and intensive postprocessing - why not switch to RAW mode?" Portrait "also goes, but is quite close to" Neutral "and instead of" Landscape " You usually take "standard".
If you select an image style, you can use the right arrow key to enter the parameter menu, which contains no less than seven entries, such as focus, detail contrast, global contrast, brightness, color saturation and hue. Assignment scales are assigned to all entries. The D750 has a "detail contrast" (corresponds to the "clarity" control in Lightroom). The settings can either be adjusted in steps by using the left / right arrow keys, or in quarter steps by turning the front dial.
The seventh parameter is called "Quick Fit" and is available for all image styles except "Neutral" and "Balanced". Here, out of zero, two steps are possible in the direction of minus or plus. The snap-on adjustment extends to three parameters (sharpness, global contrast, color saturation) - between minus and plus, the result of the picture changes from discreet to striking. As a starting point for your own experiments, you should take the picture style "Standard".
In addition to the Picture Control settings, there are two other ways to influence the image dynamics to master high contrasts in the subject. One is called Active D-Lighting (ADL). In automatic mode, the camera adapts the effect to the subject, with the results being unpredictable. Better take one of the four available levels Moderate, Normal, Enhanced, or Extrastark. D-Lighting brightens the shadows and improves the light drawing. The best way to do this is to use an automatic ADL (individual function e6) that allows between three and five shots.
Another way to compensate for contrasts is the HDR function. The camera takes two exposures with different exposures and then combines the images according to your preference - the options are Moderate, Normal, Enhanced, Extra-strong and Auto. Especially in the case of "Moderate" and "Normal", the impression of a natural contrast balancing prevails, only from "intensified" does a clear HDR effect occur, and "Extastark" sometimes reverses tonal values with occupied lights Code>
The D750 used showed a clear tendency to over-exposure, not a single case with Nikon. In order not to have to permanently activate the exposure correction, another useful function of the camera was used: the fine adjustment of the exposure measurement (individual function b6). A pre-correction in the range of +1 to -1 LW can be set separately in six steps for the four exposure metering methods offered. If you want, you can combine this with the already mentioned parameter "Brightness" in the picture.
With its 24-megapixel CMOS, the D750 achieves a high resolution over 1800 LP / BH at ISO 100, which is only about 200 LP / BH up to ISO 6400. Also high dead-values up to ISO 3200 serve as proof of the good fine-drawing with a low tendency to artifacts. Noise is visible from ISO 1600 upwards, remains up to ISO 3200 but below 2.0. The dynamic range is not particularly high with 8 to 9 screens up to ISO 12 800, but very constant. As far as the just summarized results of the lab test in ColorFoto 12/14, with which the camera could secure a top position in the picture quality.
Despite the excellent internal signal processing that Nikons D750 has to offer, it is also worthwhile to switch to RAW mode, if one wants to emit the camera from the last quality reserves. The TIFFs obtained from RAW show the surface of the test motif (metal frog) and the wall structures with clearly improved fine-tuning. No disturbing edge elevations can be observed at light-dark interfaces. In addition, you are rewarded by more balanced contrasts.
The RAW advantage is already apparent at ISO 100 and remains present even at higher ISO settings. The extent to which differences are visible, however, also depends on the respective motif. Therefore, if possible, take RAW and JPEG in parallel to get a direct comparison.
