bokeh, aperture, focal length

I like to shoot, at times, basically portrait/macro style, photos with a lot of bokeh. The convention wisdom is use the largest aperture available. But we need to keep focal length in mind.

A few days I was taking what I call "a walk around" shoot. My camera settings were, M, Auto ISO 100-1600, f/5.3, 800s. I took a photo of a flower filling the frame focal length 112mm. A little later I took a photo of a garden rabbit. But the focal length was 18mm, f/3.5.

The bokeh on the flower was great but everything in the garden rabbit was all in focus, no bokeh.

So the convention is a faster lens would give a greater bokeh one needs to consider the focal length too. I am shooting with a Nikon D5500 using a  18-200mm Nikon lens.
