Nikon D750: Nikon... You've created a monster



I copy this articel from petapixel.com because i really amaze with Nikon D750, One thing that shock me is Nikon D750 still give an acceptable image even the picture force to take under 5 stops.

Extreme Sensor Test: 5 Stop Under Exposure 

While not a real world example (unless you have serious exposure issues!), below is a 5 stop under exposure at ISO 100. The same gear and settings as before, the Nikon 35/1.8G using 12bit Lossless Compressed RAW recording.


The above image, imported into Lightroom with the exposure pushed +5 stops, is below. Mind boggling detail recovery! The depth of detail in the dark shadow areas seems to defy logic, they are essentially black in the original image. Stunning.



The 5D3 version has consistent banding and a tartan-like chroma noise. Chroma noise is the type you don’t want, it’s very hard, if not impossible, to fix in post. Even in black and white it looks blotchy. Lower dynamic range is the reason the colours are poor; I couldn’t actually get the whites white without making the rest of the image look unnatural. There is also detail loss in the dark areas.

To save you scrolling I’ve placed the D750 version below again for quick comparison. I repeat, this is not a real world example, it’s simply testing the furthest reaches of the sensor. The Canon 5D3 is a very good camera and it has served many professionals very well indeed. It just shows how good that D750 sensor is, and it’s great to know that capability sits behind your RAW files.

Nikon D5500



The world's smallest, lightest, and slimmest digital SLR camera, and the first Nikon digital SLR camera to be equipped with a touch screen vari-angle monitor and built-in Wi-Fi® function



The D5500 is the world's smallest, lightest, and slimmest digital SLR camera, and the first Nikon digital SLR camera to be equipped with a touch screen vari-angle LCD monitor that supports intuitive touch operation as well as a built-in Wi-Fi® function. The D5500 offers superior image quality and rich reproduction capabilities for excellent detail with an effective pixel count of 24.2-million pixels, a Nikon DX-format CMOS sensor, and the EXPEED 4 image-processing engine.

Adoption of a monocoque structure made of a carbon-fiber composite material, and a completely new layout for the internal structure have achieved a smaller, lighter, and slimmer camera while preserving great strength and durability. In addition, the slimmer body makes for a deeper grip that provides a firmer, steadier hold as well as superior portability.

The D5500 supports a broad range of standard sensitivities, from ISO 100 to 25600, for superior image quality that is stable and reliable, even with shooting in dimly lit situations. What's more, Super Vivid, Pop, and Photo Illustration options have been added to Special Effects mode, one of the functions that supports the rich power of expression possible with the D5500 with selection and specification of a variety of effects with shooting, making photography even more fun.
