Hi all,

I’m trying to better understand relative focal length. I shoot with a Nikon D500 (APS-C) and up until now have done mostly sports photography. I’m trying to get more into street photography but trying to understand what I’ll be shooting with based on the lenses that I currently own and I’m a little confused. Can you please confirm if my thinking here is correct.

Here are the lenses I currently own and (my assumption about the relative focal length with this crop sensor camera):

  • Nikon AF-S 70-200mm f/2.8E FL ED VR (105-300mm)
  • Nikon AF-S 50mm f/1.8G (75mm)
  • Nikon AF-S 35mm f/1.8G DX (35mm since it’s a “DX” lens)

Are my assumptions correct? If so, do I not have a true 50mm focal length lens for this camera body? I was looking to shoot with a 50mm to start out my street photography journey.

Thank you for the help.

    For understanding crop sensors I like this diagram. Seeing it this simplified makes it very clear what the difference is. The amount of light coming in is always the same. The only difference is the size of the sensor that sits at the focal plane is smaller
