Make it paw-some
Mirrorless cameras like those from the Z series will do a great job of photographing felines in their natural state. As playful cats can be rather unpredictable when they are active, the burst mode or continuous shooting mode will come handy here and you can choose the best shots from the series. The mirrorless system also includes the handy Animal-Detection Autofocus. The camera will automatically detect and focus on the cat's eyes or face, depending on the distance, making it easier to ensure you capture your shot in sharpness. Additionally, the intuitive subject-tracking autofocus also captures the cute kitty’s movements as it crawls or climbs.
Once you see that the cat is relaxed and lounging, you can switch to the manual function to experiment with the best settings to capture them in their element. This is also a good time to use the zoom function to get details of the cat, such as its paws, nose or whiskers, when they are resting or asleep. A mid-range zoom lens between 50mm and 120mm would suffice and you can also toggle between wide or narrow apertures, depending on whether you’re taking the face or body of the cat. The NIKKOR Z DX 18-140mm f/3.5-6.3 VR or NIKKOR Z 24-120mm f/4 S would be good options for achieving such shots of your pets.
