Studio report: Nikon D5 has lowest base ISO dynamic range of any current FF Nikon DSLR
1 Exposure Latitude
When the Nikon D5 arrived in our office on Friday we immediately wanted to answer a few questions: How is the low light performance? How good is the autofocus? How is the Raw dynamic range? After running our Exposure Latitude and ISO Invariance tests we've found that while the D5's sensor is clearly optimised for low-light image making, it represents a rather surprising - and disappointing - step backwards in terms of low ISO dynamic range.
Let's take a closer look, starting with our Exposure Latitude test scene. There are two pages in this article, so don't miss page 2, where we'll look at ISO invariance.
In this test we look to see how tolerant of pushing exposure the D5's Raw files are. We've done this by exposing our scene with increasingly lower exposures, then pushed them back to the correct brightness using Adobe Camera Raw. Examining what happens in the shadows allows you to assess the exposure latitude (essentially the dynamic range) of the Raw files.
Because the changes in this test noise are primarily caused by shot noise and this is mainly determined by the amount of light the camera has had access to, the results are only directly comparable between cameras of the same sensor size. However, this will also be the case in real-world shooting if you're limited by what shutter speed you can keep steady, so this test gives you an idea of the amount of processing latitude different formats give.
Even at a modest 3 stop push, we see the D5 has already contributed a considerable amount of noise to its low ISO images compared to the 24MP D750. After a 5 stop push the gap widens, with the D750's 5 stop file looking more like the 3 stop file from the D5. In fact, the D5's performance closely resembles the performance seen from the, with just a bit more color noise showing in the 6D's file.
After very aggressive pushes, an interesting series of bands appears at the top and bottom of the image. We don't know what's causing this additional noise (which appears to be confined to specific read-out rows) but it's interesting to note.

Canon has announced its latest superzoom camera, the PowerShot SX70 HS. Compared to the SX60 that came before it, the SX70 has a longer lens, higher resolution EVF, 4K video capture and support for Canon's new CR3 Raw format.
Cosina has announced its eighth lens designed specifically for Sony's E-mount system. The Voigtlander 21mm F3.5 lens is due out October 2018.
Sony has taken the wraps off of its new 24mm F1.4 GM full-frame lens, which the company claims is the lightest in its class. Despite its fast aperture, the 24mm F1.4 is remarkably light, weighing just 445 grams (15.7 ounces). The lens will set you back $1400 when it ships next month.
In this episode of DPReview TV we take a look at Sony's brand new 24mm F1.4 GM lens, a desirable focal length for many photographers. How does it perform? Chris and Jordan give us their first impressions.
We've had a little time to shoot with Sony's new wide/fast prime, both close to home and on the water in San Francisco. Check out our initial sample images.
Fujifilm released a firmware upgrade for its X-T3 mirrorless camera that addresses issues with distortion compensation and the mechanical lock on SD cards.
The app's algorithms have been trained using using 200 million cropping data points from real photographers.
Thanks to a software update, the Loupedeck+ editing console can now be used for video editing.
British photographic engineer MTF Services is claiming the world’s first third-party lens adapters for the new Nikon Z system with a collection of four units designed to allow cinema lenses to be mounted on the mirrorless full frame bodies.
Think Tank Photo has updated its line of heavy-duty rain covers and introduced a new, compact version for emergency situations.
The X-T3 is our first opportunity to analyze what's likely to be Fujifilm's next generation image sensor. Take a look at how it performs next to the competition in our studio test scene.

Canon and Nikon finally entered the full-frame mirrorless market this summer with the brand-new RF and Z mounts. Now that we've had some time with the cameras, we wanted to revisit our earlier predictions and take stock.
The devices' camera specs look pretty much identical to last year's iPhone X but under the hood a number of important improvements have been made.
Blackmagic Design has announced the public beta of its new Blackmagic RAW video codec. The company says the new format combines the benefits of shooting Raw video with the ease of use and smaller file sizes usually associated with non-Raw video files.
