My Nikkor Z 105mm has a reproduction ratio of 1:1 and from what I read the lens is therefore perfect for macro. I've read a lot about it, including here on DPReview, but I'd like to see it in front of me. So, does anyone have examples of macro photos where 1:1 is and where it isn't? Because I try to visualize it in order to understand properly the benefits of this for macro photography.

1:1 is when the image is exactly the dimensions of the sensor.

If you placed a US dime on an area that size, that's what you would see in the frame.

Any example of 1:1 with a full frame body would be the same. I think a US quarter fills the frame from top to bottom at 1:1 with full frame.

hmm, not sure thats right. if you focus on a dime @ 1:1 the dime will be the same size on both apc or ff sensors, but as the ff has a bigger sensor there will be more space around the edges

try this from allan wells Sensor Size and Magnification - correcting a common misunderstanding - YouTube
