This was taken with a 28-105 lens zoomed out to 105. I know she hates having her picture taken so while we were at the zoo I waited for her to get distracted and had my camera pre-zoomed on her head when she looked away and set it to aperture priority with the lens wide open and multiple shot mode.
The whole time I had to keep talking to her to keep her from getting suspicious then i made some stupid joke and waited for her to look over. As soon as her head turned i started shooting and got like 5 shots, this was the best one.
She told me she would kill me, but then relented when I showed her the shot.
