The more or less standard way to photograph something up close. Use a medium tele, in this case a 135mm and shoot wide open (lowest f/stop number” for that beautiful bokeh or blurred background. It’s also a good idea to experiment with 2 or 3 different f/stops for different effects.
This is the way most people like to do their close-up photography.
I however, have a different solution, for a more different and “wilder look”.
I use the Nikon Fisheye for a lot of my closeup imaging. I set the f/stop at f/2.8 for maximum bokeh.
The flowers are starting to bloom, so now is a good time to stock up on lenses. Don’t be shy about using Nikon’s Fisheye. It rocks!
