Taking images with bokeh effect on background

Yesterday I went to local furniture store and took pictures of their abandoned furniture by the store. The object (sofa) turned out nicely but the background was busy. I tried setting aperture to 2.0 but it only allowed me to set it to 5.0 (the lowest) if camera is selected to AV (aperture value). My ISO was 100 since it was a sunny day.

I look at magazines and other photographers websites where an object is in good focus but rest of background is blurry. Is there a way to archive such effect without using a Macro lens and not to use photoshop (Gausian Blur)?

First of all, there is no such thing as a "bokeh effect". The term "bokeh" refers to the undefinable and unmeasurable aesthetic qualities of background blur in images. "Bokeh" is not a synonym for "background blur".

You'll need either or both of two things.

One tool is a lens which has a larger maximum aperture (lower numbered minimum f-stop) so that you can use the wider apertures.

The other thing you can do is to physically change the relative distances between the subject and the background. Getting the background further away will cause it to be more blurry if all else is equal.

maximum aperture is a feature of the lens, you need a different (and usually more expensive) lens to have a wider aperture and blow out the background further. Well, that's a simplification but just a simple answer to the question. It also depends on how close you are to your subject, how long of a lens you are using, how far away the background is from your object, how big the sensor is in your camera.

It sounds like it may not be possible to blow out the background and get the "bokeh effect" in your situation without a different lens or different setup.

Ok thanks everyone. I'll work on exploring my lens options and will read arm's link. Thanks!
