Two Very Different Cameras
These cameras share a sensor format, but they were designed for different people. The Z50 targets enthusiasts who want a small, easy camera. The D500 was Nikon’s top DX body, aimed at working photographers who needed speed, durability and deep controls.
Main Differences
- Body type: The Z50 is mirrorless with an electronic viewfinder. The D500 is a DSLR with an optical viewfinder.
- Size and weight: The Z50 is much smaller and lighter.
- Build and controls: The D500 has a larger grip, more buttons and dials, and a tougher body, as the maker describes it.
- Autofocus for action: The D500 is known for a capable phase-detect focus system built for tracking sports and animals. The Z50 offers modern eye and subject detection on its own terms.
- Card slots: The D500 has two card slots, while the Z50 has one. Confirm slot types with Nikon.
- Lens mount: The Z50 uses Z mount. The D500 uses F mount, with a huge range of older lenses.
Choosing by Purpose
- Travel and daily carry: Choose the Z50. It fits in a small bag with a compact zoom.
- Sports and wildlife: Choose the D500 if you already own or can use F-mount telephoto lenses.
- Video: The Z50 is generally the more current choice for video features and live view focus.
- Battery life: An optical viewfinder camera often lasts longer per charge than a mirrorless one. Check the maker’s battery figures on their page.

Lenses and the Long Term
The D500 is part of an older system, but F-mount lenses are plentiful and well established. The Z50 is part of a growing system that Nikon is actively developing. If you want the freedom to move to full frame mirrorless later, the Z mount keeps those lenses useful. If you already have F lenses, the D500 or an adapter on a Z body might protect that investment.
FAQ
Can I use F-mount lenses on the Z50?
Yes, with Nikon’s mount adapter. Autofocus support varies by lens type, so check compatibility.
Which is better for birds?
The D500 is a known bird and sports body. The Z50 can work well with a suitable telephoto lens in good light.
The Short Version
Choose the Nikon Z50 for a small, modern camera for travel and everyday use. Choose the D500 for rugged build and action-focused shooting, especially with F-mount lenses. Match the body to your subjects.
