Nikon's first high-resolution Z-mount mirrorless — 45.7MP with 493-point hybrid AF and 5-axis IBIS.
The Nikon Z7 was released in September 2018 as the flagship of Nikon's Z-mount mirrorless launch, providing a 45.7MP BSI CMOS sensor with 493 phase-detection AF points covering approximately 90% of the frame. 5-axis IBIS provides approximately 5 stops of compensation. 4K/30fps records with a 1.08x crop. At approximately 675g with battery and card it is substantially lighter than the D850 DSLR with comparable resolution. The single XQD card slot received criticism at launch.
The 45.7MP full-frame BSI CMOS sensor pairs with EXPEED 6. The 493 phase-detection AF points cover approximately 90% of the frame. Burst shooting runs at 9fps. 4K/30fps records with a 1.08x crop from the full sensor. 5-axis IBIS provides approximately 5 stops of compensation. Battery life approximately 330 shots using the EN-EL15b — notably low for a full-frame camera. Body weight approximately 675g with battery and card, single XQD card slot (CFexpress Type B added via firmware update).
The Z7's 45.7MP at 675g was a significant weight reduction versus the D850 (1005g) at comparable resolution, demonstrating the compact Z-mount body advantage. The ~330-shot battery life was the primary criticism at launch — the smaller body used a compact battery at meaningful cost to performance compared to contemporary DSLRs. The 5-axis IBIS provided full-sensor stabilisation not available in any comparable Nikon DSLR. The Z7 II (2020) improved battery life and added dual card slots.
On the used market the original Nikon Z7 is affordable as a 45.7MP mirrorless body. Condition checks: shutter count via EXIF, single XQD/CFexpress card slot contacts, IBIS operation, and EN-EL15b battery health — shared with the D750, D850, D610, and Z6/Z7 II. The Z7 II provides dual card slots and improved battery at a modest premium. Compatible with all Nikon Z-mount lenses; Nikon F lenses via the FTZ adapter.
