Can you combine these two?

Last updated: December 2024

This is the short answer:

Yes! This combination is compatible (but with no Autofocus)

The camera and lens you have chosen can be used together but you will only have manual focus.

Lack of Autofocus

The lens supports autofocus but neither the camera nor the lens has a built-in autofocus (AF) motor. You as a photographer will not have the possibility to use autofocus to obtain a sharp image. Focusing manually will then be the only way to obtain sharpness.

Focal Length

The Nikon camera has a sensor of type DX, a smaller version compared to a Full frame sensor, which means that your experienced Focal length will be multiplied by 1.5x.

This lens has focal length:
20 mm

Since Nikon D3000 does not have a Full Frame sensor the experienced focal length you will experience will be:
30 mm
