The 100-year-old Nikon, originally known as Japan Optical Industry Co., Ltd., has had the legendary classic model Nikon F, with NASA spacecraft in space, but also with photographers to all corners of the earth, its glory continues to this day, ranking second in the interchangeable-lens camera market, in 2016 set a world record of selling 100 million lenses.
 
As a single-lens reflex giant, Canon has a conservative attitude in the field of mirrorlessness, but it has still achieved good market results with its golden signboard, while Nikon's road to mirrorlessness can be described as very bumpy. Nikon is not slow, and in 2011 it released the 1 series of mirrorless systems, but this 1 series is too low, and now the M4/3 sensor, which is criticized as too small, is much larger than the 1 series, and cannot be compared with APS-C format and full frame. Now the 1 series mirrorless has long been completely discontinued, and no one cares about it.
 
After the discontinuation of the 1 series, Nikon had no mirrorless products on sale at all, and it was not until the fall of 2018 that Nikon and Canon tacitly released a new full-frame mirrorless product, announcing their entry into the professional mirrorless camera market. Nikon has come up with two new full-frame mirrorless products, Z6 and Z7, positioned similarly to Sony's A7M and A7R, one focusing on comprehensive performance and the other focusing on high image quality. Nikon's newly designed Z-mount is larger than both the full-frame Sony FE mount and Canon's RF mount, allowing for a more convenient and free design of large-aperture lenses, with a shorter flange pitch for better edge image quality, but the huge mount also makes the body look a little incongruous.
 
Z7 uses a 45.75 million pixel back-illuminated full-frame sensor, which is consistent with the specifications of its flagship SLR D850, and still uses the sensor provided by Sony, but it is more advanced than Sony's own A7R3 42.4 million pixel sensor, and it is not an exaggeration to call Z7 the best full-frame camera on the market. The Z7's focusing system is also extremely strong, with 493 composite focus points covering 90% of the sensor area, but the 5.5 fps focus tracking continuous shooting speed is far behind the Sony A7R3, especially the cache write bottleneck is low, and the continuous shooting will slow down quickly, which is not suitable for capturing moving objects, and it is the best use case for shooting still pictures, which can give full play to the advantages of Z7's high pixels.
 
The Z6 features a 24.5-million-pixel back-illuminated full-frame sensor, positioned equivalent to the Sony A7M3 or Canon EOS R. The Z6 achieves a maximum continuous shooting speed of 12 frames per second, but the focusing system is a bit lower than that of the Z7. Both the Z6 and Z7 support 4K-30P video shooting, and N-Log recording is also supported, which greatly improves video post-processing. It's worth mentioning that neither camera supports dual card slots, and doesn't support mainstream SD cards, but instead uses a very niche XQD card, which is relatively expensive.
 
Both the Z7 and Z6 have excellent product power, with DPReview named the Z7 the best high-end interchangeable-lens camera of 2018, and the Z6 also receiving several nominations. But when combined with the selling price, these two products are not worth buying at the moment. First of all, the Z6 body costs more than 17,000 yuan, which is thousands of yuan more expensive than direct competitors Sony A7M3 and Canon EOS R. And Z7The price is more than 25000 yuan,As the main high-pixel image quality machine,The price is much higher than that of Sony A7R3 of the same level,Close to the medium-format Fujifilm GFX-50R。 Second, Nikon's full-frame mirrorless system faces the same dilemma as Canon's shortage of lenses, and it needs to rely on the transfer of past SLR lenses to survive, which will bring certain inconvenience and performance losses. Unless you own a lot of Nikon SLR lenses, or if you have a huge discount on Nikon, it is not advisable to buy these two models too early.
