Nikon D610 user manual

The Nikon D610 is classified as an advanced enthusiast-level camera rather than a professional-grade camera. It boasts several professional-level features and specifications, such as a full-frame sensor, robust build quality, and advanced image quality capabilities. However, it lacks some of the advanced features and ruggedness found in higher-tier professional cameras like the Nikon D5 or D850. Therefore, while the D610 is great for serious enthusiasts and entry-level professionals, it may not meet the specific demands of certain professional photographers in demanding environments or specialized fields.

No, the Nikon D610 is not in production anymore. It was officially discontinued by Nikon in 2020.

The Nikon D610 was released in October 2013, so as of 2021 it is around 8 years old.

On a Nikon camera, the P mode stands for Program mode, while the A mode stands for Aperture Priority mode.
Program mode (P) is a semi-automatic mode where the camera automatically selects both the aperture and shutter speed settings. However, the user still has the flexibility to make adjustments to various other settings like ISO, exposure compensation, white balance, etc.
Aperture Priority mode (A) allows the user to manually select the desired aperture value, while the camera automatically adjusts the corresponding shutter speed to maintain proper exposure. This mode is particularly useful when controlling the depth of field or when shooting in low-light situations.
In summary, the P mode provides more automation and ease of use, making it suitable for beginners or situations where you want the camera to make the majority of exposure decisions. On the other hand, the A mode grants the photographer more control over the aperture setting while still benefiting from the camera's automatic adjustments.
