On the other hand, the Nikon Z 7II has powerful autofocus performance, enhanced by dual processors.

Build and Durability
The OM SYSTEM Olympus OM-1 Mark II is built to withstand challenging environments, boasting an IP53 weather-sealed design that ensures protection against dust and moisture, as well as freeze-proof capabilities down to -10℃.
