The Nikon Z7 II has two EXPEED 6 processors, which improves the buffer, autofocus, and continuous shooting speed features. Burst Shooting The native ISO range of the Nikon Z7 II is impressively wide, from ISO 64 to ISO 25600 (32-102,400 expanded), somethings that's also true of the Z6 II, which runs from ISO 100 to ISO 51200 (50-204,800 expanded). Decided to check where Z7 stands as compared to the claimed buffer. A photographer with the Z7 II … The Z7 II offers an extra stop at the lower end and the Z6 II an extra stop at the higher end. The additional processing power of the extra chip also sees the Z7 II able to clear its buffer much faster than the Z7, with Nikon claiming it to have up to 3.3x the buffer capacity (shooting 12-bit lossless compressed raw files to a CFexpress card). It is a pleasure to carry around and shoot with, and when coupled with Nikon’s new Z lenses, it can produce stunning images with very high levels of detail that the Nikon F simply cannot match. Combining the advantages of a lightweight mirrorless design, a revolutionary new full-frame lens mount and matched lenses, a Nikon designed 45.7MP image sensor and seamless integration with Nikon’s DSLR system—including the Nikkor lenses you love—the Z 7 is a camera unlike any before it. Another difference concerns the buffer depth. Although Nikon hasn’t given us any official data to go on, the lower resolution of the Z6 should help here as well. Using a card in the camera dropped the buffer number to 17 or 18 shots. The Z7 was able to shoot 17-20 shots at full frame rate before the buffer was full and the frame rate dropped to accommodate the write speed. "I greatly prefer operating the Nikon Z7 over the Sony A7R III. Nikon Z7 Buffer Depth - Holy Cow! In my view, the Nikon Z7 and Canon EOS R are already superior in ergonomic/haptic terms to any model Sony camera." The frame rate with the buffer full averaged up to 2.8 fps. An advantage of the lower megapixel count is that the Z6 can shoot up to 12fps, whereas the Z7 stops at a maximum of 9fps. While the Sony A7R IV will surely be improved, Sony is clueless about building cameras with the right ergonomics/haptics; that is a key strength of the Nikon Z7. The Z 7 brings that vision to life (and then some). Still, the Nikon Z5's dual UHS-II SD card slots is certainly a bonus considering Nikon's approach to the Z6 and Z7, and gives it an edge over the Canon … NIKON Z 7 + NIKKOR Z 24-70mm f/4 S @ 70mm, ISO 100, 1/2000, f/8.0 Still, despite all of its shortcomings, the Nikon Z7 is an impressive mirrorless camera. However, Nikon added quite a bit of horsepower in the second generation cameras with dual EXPEED 6 processors, in addition to significantly increasing camera buffer. The slowest card provided only 0.5fps with the buffer full. Nikon Z7 II vs Z7: Video 4 months ago 23 Today I was checking out Sony R IV and just tested its buffer depth, it came out to be a little less than advertised but it was in ball park. The second processor results in the Z7 II capturing 12-bit raw images at 10 frames per second, versus the 9fps offered by the Z7, and with a 3.3 times larger buffer (77 frames versus 23). Ergonomically, there are practically no differences between the first and the second-generation Z6 and Z7 cameras.
