The source has published updated and enhanced specifications of the mirrorless Nikon Z 6s and Z 7s cameras, preliminary information about which appeared earlier this week. According to him, the cameras that will be a development of Nikon Z 6s and Z 7s may be called Nikon Z 6II and Z 7II.
By inheriting the image sensor from their predecessors, the new cameras will also be similar in shape and size. The electronic viewfinder will also be preserved (it was previously stated that its resolution will be increased from 3.69 million dots to 5.76 million dots).
At the same time, the automatic focus system with face, eye and animal detection functions in the frame will be improved. The dual EXPEED processor will increase the frame rate when shooting video (in particular, 4K video can be shot at 60 fps), and in general, the functionality associated with video will be enhanced.
The cameras will receive more buffer memory, an improved user interface and a new Nikon EN-EL15c battery. There will be two slots for memory cards: CFexpress and SD (with support for XQD/CFX Type B and UHS-II). USB power is provided. It is claimed that the Nikon Z 6s camera will be the last Nikon camera with a 24 megapixel sensor.
After the release of the cameras, expected in October, will be released firmware update that improves their functionality. According to preliminary data, the new cameras will be more expensive than the current Z 6s and Z 7s, which can now be purchased for about $1800 and $2500, respectively.
